As this is still a very early pre-release version, +and I'm neither much of an autoconf or make wizard, building +the patched junkbuster involves some manual work, that is +described below. Please also see the Request for Thoughts section, +as the whole point of this pre-release ist to collect ideas for +improvement and bug reports. + + +INSTALLATION: + + - Get and install pcre from + ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ + Version 3.1 or any later one will do. I recommend 3.4. + It *should* install on Win32 as well, but I haven't tried + that. Don't forget to run ldconfig afterwards. + + - Now you have two options: + + A) Install pcrs as a shared library: + pcrs.c and pcrs.h are included in the (patched) ijb subdirectory. + 1.) patch Makefile < Makefile.re_shared.diff + 2.) gcc -Wall -fPIC -c pcrs.c + 3.) gcc -shared -Wl,-soname,libpcrs.so.1 -o libpcrs.so.1.0.1 pcrs.o -lc -lpcre + If this worked OK, + 4.) copy libpcrs.so.1.0.1 to /usr/local/lib + 5.) ln -s /usr/local/lib/libpcrs.1.0.1 /usr/local/lib/libpcrs.so + 6.) ldconfig (Or whatever the equivalent on your platform might be) + 7.) cp pcrs.h /usr/local/include + + OR + + B) Incorporate pcrs into the junkbuster (much easier): + Smile and relax. You're done. + + - Edit the provided re_filterfile to suit your needs and place it + with the rest of junkbusters configfiles. + + - Now junkbuster should build with a simple 'make'. + Note: Setting debug = REF in jcc.c will enable debugging + for the re_filter. + + - Include a line "re_filterfile " in your junkbuster + config file, pointing at the re_filterfile + + - (Optional:) Include a line "re_filter_all" in the config + file. This will set the Policy to filter content from all sites. + Default is to filter only from sites that you wouldn't send a + cookie either. + + - Fire up junkbuster. + +HOW IT WORKS: + + Nah, not tonight anymore ;-) + +REQUEST FOR THOUGHTS: + + - The main decision is whether to filter on-the-fly or to buffer + up the whole document and then run the filter on it. I've built + both versions and currently prefer buffering. + + The advantage of on-the-fly-filtering is obviously that the + document begins to display before it's fully loaded. The big + disadvantage is that with arbitraty content altering in place, + you don't know the size that the document will have after + altering when the Content-Length Header is to be sent. Only + option is to chew it altogether. + + Apart from preserving the ability to generate a valid Content-Length + header (which the patch currently does not yet do), buffering up + the document has some advantages from the filtering point of view: + + - Reliability. Patterns in the document cannot be ripped apart + and are reliably found. (If you look at the document fragment-wise + while it's being transmitted, you miss any pattern that spans + a fragment border) This is especially bad for patterns that do + serious HTML reformatting, as fragments are typically in the order + of 1500 bytes each. + + - Flexibility: The re_filter gives you the choice whether you want + to replace only the pattern's first occurance or replace it globally. + This becomes meningless with fragments. (Solution possible, though.) + + As the filter only processes objects of MIME type text/*, which are typically + rather small compared to binary multimedia (sic) type data, I don't think + that the disadvantage of delayed display of the first bytes is really grave. + + What do you think? + + - Is the choice between a radical (filter all) and semi-smart (filter only when + also crunching cookies) flexible enough? Should I really introduce yet another + configfile for specifying the domains to filter content from? Would anyone use + that? + + - Should I use pcre as a shared library and work out a nice installation + automagic, or should the relevant functions be incorporated in re_filter.c? + + - Even if yes, do we really want an extension that relies on an external library + like pcre? + + - Any bugs, stupid parts in the code ? + + - Cool suggestions for the re_filterfile? (PLEASE!) + + - Should character set translation along the lines of Perl's 'tr' operator + be included? + + - Is the whole feature just pathetic? + +FEEDBACK: + + A whole lot of work has gone into this feature (the pcrs code was also + just written for this) and I'd really like to know if and how you like + it. Since I'm more of a perl than C programmer (and after doing so much + string manipulation in C I'm once again glad abaout that!), I'm sure there + is much to improve. Please send any suggestions/observations/hellos to + oes@paradis.rhein.de. I would also be very glad about any assistance for + a autoconf/make procedure for prcs. + +Well, have fun! +--Andreas + + +***************************************************************************** +* Copied from old README.cygwin * +***************************************************************************** + +Id: README.cygwin,v 1.2 2001/04/29 23:16:29 rodney Exp + + +What I did: I saw too many "personalities" in IJB; so I +ran the code through a couple of regexp's and then let XEmacs +reformat the whole shebang! The results is a uniform +looking code base; aka. as if 1 person created the whole +project. + +Why I did it: (1) it is easier to maintain (2) easier for +a new person to make changes/additions (3) it *looks* more +professional (4) IMHO, it is easier to read (this is very +much a personal preference). + +What I propose: A IJB standards list be included in the +distro and all source/patch checkins be checked for +compliance. We don't need to be an arse on this point, but +submitters should make a valiant attempt to support the +standards. + +Note: do not even try to diff my code with another code +base, you will be overwhelmed. After all, the regexps did a +good bit of changing and XEmacs reformatter did a great deal +more. + +One more note: these changes include conditional compilation for +un?x (namely Linux), cygwin (un?x like compile for WIN32), and +mingw32 (WIN32 like compilation w/o VC++). Right now, all seems +fully functional except cygwin. The cygwin compile will work, +but includes code to make it single threaded. I need to debug +the fork issues, but that will have to come later. + + +Specific changes to expect: + + +1: I've majorly reworked the Makefiles. The existing Makefile was +too *spaghetti* for me! For one, I eliminated the "-I." from the +include path (ugly). Use #include "" for local directory files +and #include <> for path found files (that's basic even to c). + + +2: In accordance with #1, I changed #include "windows.h" to +#include and #include to #include +"gnu_regex.h". + + +3: As part of my standards suggestions (to come later in this +file), I added a standard comment block to every function. There +were too many functions with *no* comment and about 20 different +styles to those that did. This is an example of the block I used: +/********************************************************************* + * + * Function : block_acl + * + * Description : Block this request? + * Decide yes or no based on ACL file. + * + * Parameters : + * 1 : src = Address the browser/user agent is requesting. + * 2 : dst = The proxy or gateway address this is going to. + * 3 : csp = Current client state (buffers, headers, etc...) + * + * Returns : 0 = FALSE (don't block) and 1 = TRUE (do block) + * + *********************************************************************/ + + +4: Some files prototyped like this: + void + func(param1) + int param1; + { + } +and other like this: + void func(int param1) + { + } +I made all look like the second. + + +5: Made: + if( to be if ( + while( to be while ( + switch( to be switch ( + etc ... +The former looks too much like a function call. + + +6: Put braces on their own line and aligned under the +reserved word: + if () { + } else { + } +to be: + if () + { + } + else + { + } +The same for while, do, etc... + + +7: Casted malloc in several places, e.g.: + p = malloc(n); +to be: + p = (char *)malloc(n); +This eliminates compiler warnings. + + +8: Applied the Perl regexp patch and made it fully conditionally +compiled (-DPCRS=TRUE). + + +9: It *appears* that if MINGW32 sees a "main" function, it will +try to link it and start with main (ala console mode). Since I +need MINGW32 to find WinMain instead, I conditionally changed +"main" to "_main" (for MINGW32 only!). + + +10: Changed popup.c to be killpopup.c. This was necessary to +clean up the Makefile. Since there was an ini type file called +"popup" and "popup.c", make got confused on target names. No +other ini file has a .c file with the same name, so I hope this +isn't a big deal. Plus, it fits its config variable +(kill_all_popups) much better. + + +11: Added: + /* + Local Variables: + tab-width: 3 + end: + */ +to all .c and .h files. I use 3 character tabs and this will make +the files display correctly in Emacs editors. This is just my +default setting. Perhaps I will filter all files via "expand +-t3", so not to pi$$ everyone off. Vi is capable of using 3 +character tabs, as I am sure VC++ would be. + + +12: Several places included regexp code with out "#ifdef REGEX" +which broke the ability to compile w/o regexp's. I fixed the code +and can compile w/o regexp (which I don't normally do, but now I +*can*). + + +13: In WinMain, changed: + pszLastTok = strchr(pszLastTok, ' '); +to be: + pszLastTok = strchr(pszLastTok+1, ' '); +The former causes an infinite loop with 2 or more parameters. + + +14: Added my own strdup for Cygwin, see jcc.c for why. + + +15: Added defines in the Makefile and this to jcc.h: + #define VERSION VERSION_MAJOR "." VERSION_MINOR "." VERSION_POINT +This makes "update the numbers also in jcc.h manually" unnecessary +(see your Makefile for this quote). + + +16: Split the "inifiles" target in Makefile into separate targets, +this way each file can be regenerated individually according to +the same implicit rule. + + +17: With the Makefile restructure, I can only provide for +Cygwin/gcc. Hopefully this is a bit cleaner and others can add +their compilers w/o re-spaghetting the file. I have provided +several makefiles as examples only, I do not intend for the +project to start maintaining multiple Makefiles. Perhaps some of +the platform specific Makefile code could be split out into +separate files and we could use the "include" directive to read in +the correct one. + +Better than this, let's get a configure.in guru on the project and +dynamically create the Makefiles! + + +18: In an effort to get this to market (you knew this was coming +eh?), I am going to put the standards suggestions in another file +and ship this one as is. But then, you can probably guess most of +the standards by the changes you see. + + +19: Added a really quick and dirty "install" target to the +Makefile. This needs to be cleaned up and proper directories put +in for each platform. + + +-- release 1 (obsoleted) -- + + +20: Incorporated the TOGGLE and webDAV support patches into my +Cygwin patch. I added conditional compilation to both features. +I changed "extern BOOL g_bToggleIJB;" to be of type "int". This +makes jcc.h independent of "windows.h". The inclusion of such +should not (and is not) necessary for compilation on all +platforms. Besides, BOOL is really only a char or an int anyway! + + +21: Added a new ini! I modified the usual un?x type config file +to M$ type ini file for a Perl regexp compile. This was necessary +to call EditFile on the Perl regexp config file. The new ini +filename is "sregexp.ini" (naturally). I then added menu items to +edit the popup.ini and sregexp.ini files. + + +22: I made "dot h" files for all the "dot c" files. I used this +command to do the *dirty* work: + grep -e "^[A-z]" *.c | sed -e "/=/d" -e "/^[^(]*$/d" \ + -e "/^extern/d" -e "/^static/d" -e "/;$/d" + +And I made each "dot h" file be immune to multiple inclusion via +conditional compilation. Ie. the "jcc.h" file will only include +itself if _JCC_H is undefined. + +After this was done, I compiled the project source by source and +let the compiler tell me what each file was dependent on. Once I +got all the objects to compile, I included the new dependencies in +the Makefiles. + +BTW, I intend to get the Makefile to be generated by a configure +script. Whether this is a GNU "configure.in" type file or a shell +script, I do not know. All I do know is that this is a must for a +"Go/No go" type decision. We cannot proceed with the philosophy +"leave it up to the user to get it to work". + + +23: I broke out the code to load the config file from main. I put +this code into a function called load_config. I made this routine +be called from a signal "HUP". This means we can restart +junkbusters from the command line or from the daemon script via +"restart" without actually killing it and restarting it. This is +common behavior to un?x daemons (see inetd for example). I fixed +the junkbusters.init script to take advantage of this. I intend +to make a M$ menu complement to this as soon as I can. + + +24: BTW, if you have not already noticed by my postings and/or +code, I have added patches and made them all conditionally +compiled. Ie. #ifdef TOGGLE, #ifdef WEBDAV, #ifdef PCRS, etc... +I think that all extensions to IJB should be submitted in this +way. Not only can you compile IJB to be as "tight" as you want, +it also gives the user a "smorgasbord" of options to +choose from. This is quite common in the free software world (you +need look no farther than emacs to see this) and provides maximum +flexibility. + + +25: As promised, I obsoleted the "ijbw32.ini" file. I was a bit +confused by the "close-behaviour=1" entry. It seems to me that it +duplicated the "close-button-minimizes=1" entry. And (by looking +at the code) it was unused. Anyway, I eliminated the "ijbw32.ini" +file and assimilated the settings into the config file. Bye Bye +"ijbw32.ini", hello "config" (aka. don't unnecessarily duplicate +files and/or data types). + + +26: Eliminated re_filter.c. This only defined +(un)load_re_filterfile and re_process_buffer. I moved +(un)load_re_filterfile to loaders.c and re_process_buffer to +filters.c. I also modified the Makefiles to reflect this. In the +doing, I modified the loader and unloader to use the "files" +variable and moved joblist to "re_filterfile_spec" struct. I +added "plist" to the client_state so that all Perl regexp code +could find the latest parsing of the re_filterfile ini. + +This is in keeping with the IJB data structures philosophies. + + +27: Eliminated acl.c. This (as pcre) only defined +(un)load_aclfile and block_acl. I moved (un)load_aclfile to +loaders.c and block_acl to filters.c. I also modified the +Makefiles to reflect this. + + +28: Since I created "dot h" files for all the "dot c" files, I +eliminated all the "extern ...variable;" and all the "extern +...function;" statements that I could find in the "dot c" files. +Instead, I included the proper "dot h" files to do this for us. + + +29: Corrected the "install" Makefile target for un?x. I will do +the same for WIN32 targets. + + +30: Note on the "TOGGLE" patch: since I made IJB fully restartable +via a NOHUP signal; I thought the TOGGLE patch should apply to +both un?x and WIN32. Thus, I eliminated the WIN32 dependencies in +that patch and added "toggle" to the config file. Now everything +works fine for either platform. Still to come is a restart menu +command in WIN32 (See: note 23). + + +31: Just a possible programmer note, we REALLY need a generic +linked list module. Since text lists, client states, filter +files, etc... implement list creation and destruction over and +over; I suggest a generic list that can handle *any* type of list +(ala template classes in C++). If this module included an +iterator (of sorts), we could eliminate the myriad of "for ( top=x; +NULL != x->next; x=x->next )" type statements that are all over +IJB. + +After all, this was taught in the basic "Intro to Data Types" +class (for all you CS majors). + + +32: Renamed all of the .INI files to be .TXT files. I did this +because the .INI files were NOT *really* ini files; which +potentially be confusing. I used the .TXT extension to make sure +that EditFile still worked. + + +33: Removed the "initialed comments", such as "/* swa */". This +leads to less readable code (because it becomes fragmented) and +retains the "multiple personality" syndrome. Comments such as +this can always be figured out from the versioning system. Also, +these comments really should be pooled in one place : the README +files. + + +34: Perhaps we should break with the current versioning tactic of +a "tail version" and start fresh. Perhaps a new major version +release is in order? Version = 3.0.0? + + +35: Added a "Accept-Encoding: gzip" cruncher. If a stream is +compressed via gzip (Netscape specific I think), then it cannot +be modified with Perl regexps. So I added this as an option in +the Makefiles. + + +36: As promised in one of my postings, I have make a +configure-esk script to generate the Makefiles. I would still +like to have a full blown configure.in compatible system, but this +will do in the meantime. Note: this configure script covers +linux, cygwin, and mingw32. At this point I do not have VC++ to +test any of my changes. But the configure script should be +flexible enough to handle this platform. + + +-- + +Please give any feedback to the ijb egroups and, if you feel you +need quicker contact, CC me at IwantToKeepAnon@yahoo.com + +Let me say once more, this has a *lot* of changes and may (aka +WILL) break a lot of existing patches. But I hope the "idea" will +catch on. Perhaps this could be made the baseline code base and +other patches added and standardized later. + +***************************************************************************** +* Date: 7 May 2001 * +* Version: ?? * +* Description: Changes for MS Visual C++ * +* Author: Jon Foster * +***************************************************************************** +(Based on Stromlund's version 0.20) + +I have made several changes to make this compile under VC++ 97, and add new +features. + +Code changes: + +1) If you disable IJB (using the TOGGLE patch) it now turns PCRS off. +2) "Missing function prototype" warnings have been corrected by adding + appropriate #include statements +3) The _DIST_URL define removed and hardcoded. There are hardcoded URLs all + over the place that need fixing - one more doesn't matter. We do really + need to come up with a long-term solution though. (Suggestion: Host a + redirector on the SourceForge web space. e.g + "http://ijbswa.sourceforge.net/redirect.php?ver=2.0.2-10&target=faq", + "http://ijbswa.sourceforge.net/redirect.php?ver=2.0.2-10&target=download", + etc. This allows us to move the pages around easily, and the SourceForge + space can be maintained by anyone who's interested, it's not tied to a + particular individual. This is similar to the approach taken by + Microsoft and Netscape in their browsers.) +4) New file ijbconfig.h is #included everywhere. This provides me with a + place to define VERSION, PCRS, etc. You can still define VERSION_xxx + on the command line, but the other defines are in the header file. + There were just too many #defines - so many that the VC++ 97 IDE + broke when I tried to define them on the command line. We probably + should fix the configure script so that it modifies this file. +5) Deleted empty file afxres.h - we needed to use the VC++ system header + file of that name. However, it's easier to just delete it and put + the relevent #defines in w32res.h. +6) New #define: NO_PROGRAM_NAME_DISPLAY uses "IJB" as the program name in + the log file instead of "H:\Documents and Settings\Administrator\My + Documents\Prog\VC\ijb2\Release\junkbuter.exe" or similar. The reason + for this should be obvious! +7) New #define: STATISTICS enables the statistics feature +8) Statistics is thread-safe, I think. However, loading up the + statistics page now counts as a blocked request. +9) New, shorter message if a setting in the config file is recognised + but unsupported by the current build. It doesn't have "WARNING:" in + front of it either. We may want to actually take this message out + and have it just silently ignore these entries. +10) New feature: #define SPLIT_PROXY_ARGS and the show-proxy-settings + page will split each file out to a seperate page. This is + because the files are quite big, and having to do 1 extra click to + get to them is no problem. This #define also disables the + suppress_blocklists feature (because I believe the original intent + of suppress_blocklists was similar?). It also saves memory by + reading the config files to generate the HTML on the fly, rather + than storing prepared HTML constantly in memory. +11) Marked global constants with "const" attribute. This has a + knock-on effect on pointers in function prototypes, so these have + also been marked const where needed. +12) Rewrote encode.c to have tables pre-initialized, so it can be + marked constant. Also split into 3 distinct functions so that + the tables (which are realy an implementation detail) are not + visible outside that file. +13) Changes to how files are reloaded when you reload the config + file. Previous method didn't free memory (or if you uncommented + the free() calls, it was not thread-safe.) It is now handled + automatically - files are reloaded whenever the filename to + read changes, or the file's timestamp changes. The code in + loaders.c which handles this test has been moved to a single + utility function. +14) killpopup changes: + * Only compiled if you #define KILLPOPUPS + * Call to filter_popups() moved from read_socket() to chat(). + * Writing 1 past end of buffer bug fixed. + * It was scanning the whole buffer even if only partially filled. + * Moved load/unload to loaders.c and changed file handling to + follow standard. +15) Auto-detect whether we want an image or HTML implemented for + Microsoft IE. :-) + There doesn't seem to be a way to tell with the latest build + of Mozilla. :-( +16) Image file code conditionally compiled. +17) Provided option (SPLIT_PROXY_ARGS) to split the show-proxy-args + page into a main page, and then a page for each config file. + This option will also save memory by loading the files when + required for display, rather than saving them in memory when + they are initially loaded. +18) Force page loading ("noijb.") patch applied. #define FORCE_LOAD + + +Packaging changes: + +1) PCRE 3.4 (less it's test and demo programs) is now included in the + pcre directory. It will be statically linked with Junkbuster. (On + win32, DLLs cause a lot of hassle - with a library this small it isn't + worth it. I don't know if it would be better to dynamically link under + UNIX?) +2) junkbustr.dsp and junkbustr.dsw VC++97 project and workspace files are + included. +3) win32build/junkbustr.exe Win32 binary is included. It should not require + any DLLs. It was compiled with all features supported. +4) All README.xyz files put together in this file. +5) Unused files (acl.c, pthread.c, ...) deleted. +6) My block & cookie files used (based on the Waldherr ones). + +Known bug: The Adobe Acrobat 4 plug-in fails when I try to view PDF files in +MSIE. Workaround: disable "web browser integration" in the Adobe Acrobat +settings. + +***************************************************************************** +* Date: 14 May 2001 (early morning) * +* Version: Reported as 2.9.0 * +* Description: Various updates * +* Author: Jon Foster * +***************************************************************************** + +1) Now use PCRE, not GNU REGEX. I have not yet had chance to check the + syntax of the block/image/cookie file to ensure that they match what + is expected - however they seem to work. +2) Replaced "configure" script with one generated by "autoconf". Also + use a header "config.h" (was ijbconfig.h in my previous release) for + the #defines. "config.h" is now generated with "autoheader" from + "acconfig.h" and "configure.in". (Note that to install you do not + need autoconf or autoheader - just run "./configure".) + To see command-line options, run "./configure --help". + This is my first ever autoconf script, so it has some rough edges + (how PCRE is handled is the roughest). +3) Error logging code replaced with new module errlog.c, based on the + one from JunkBusterMT (but with the threading code removed). +4) Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not + apply all of these, since I had already independently done conditional + popup file, conditional image file, and integration of popup code. +5*) ACL, Jar and trust files conditionally compiled. +6*) New source file headers. +7*) Various cosmetic changes. (But I have not consistently ordered the + config files - I think that's worthwhile, but it's 1am and I want to + get this released!) +8*) RCS tags on .h files. +9) RCS tags are const char[] rather than const char *. (Saves 4 bytes + per tag ;-) +10) VC++ project files renamed to vc_junkbuster.*. +11) show-proxy-args now shows status of all conditionals, not just REGEX +12) Various functions moved around. Most notably all the system-specific + sockets code which was spread between jcc.c, bind.c, and connect.c, + has been moved to "jbsockets.c". The non-system-specific code from + connect.c and socks4.c has been movet to "gateway.c". Also, the + config file loader and the global variables it writes to have been + moved to "loadcfg.c". (Maybe this should go into loaders.c?) + And candidate for the "worst filename ever" award is "miscutil.c", + which contains, well, miscellaneous utility functions like zalloc. + (Suggestions for a better name for this file are welcome!) +13) Loaders now use a common function to read a line and skip comments, + and this function also stores the proxy_args. +14) Added ./junkbuster --help (Not for Win32 GUI) +15) Added ./junkbuster --version (Not for Win32 GUI) +16) Win32 resources are now all marked as "U.S. English", rather than + being a mix of "U.S. English", "U.K. English" and "Irish English". +17) Version number changes to 2.9.0 + +Known bugs: +- See (1) above about blockfiles. +- Sending SIGHUP (under Red Hat Linux 7.1) causes a crash. v0.21A hangs + after a SIGHUP. This needs investigating, but pthreads support will + almost certainly help here, so it may not be worth investigating + immediately. +- Compiling with shared system pcre and pcreposix libraries is supported + via a switch to configure, but completely untested. + +Please note that there are now 2^14 == 16384 combinations of conditional +defines, and 4 major compilers (VC, Linux, mingw32, cygwin) for a total +of 65536 different builds. We cannot possibly test all of them! My +standard build is "everything on", and I've tested that on each compiler, +along with a few variants. You may uncover new bugs (probably compiler +errors) if you use an exotic combination of switches. + +***************************************************************************** +* Date: 14 May 2001 * +* Version: 2.9.1 * +* Description: Various updates * +* Author: Andreas S.

+The Free Software Foundation +(FSF) +is a non-profit institution +that designed the GNU General Public License (GPL) to promote the +publication of free software. +The GPL is used by thousands of programmers +who want to give others the right to copy and modify +the source code of their programs. Millions of people benefit from this. +

+We use the GPL +to allow everyone to use, copy and modify the +Internet Junkbuster +as they wish. +Companies can use it for commercial purposes, +but they are not permitted to use it in products that they claim +as their property +without negotiating a separate agreement with us beforehand. +

+The GPL +can also be used +on documents written in human languages. +We give everyone permission to use everything on our web site under the GPL. +This means that you do not have to break copyright laws in order +to print a page or email a screen of the text to someone, for example. +Many sites do not permit you to do these things. +

+If you have a home page, +we recommend that you consider using the GPL to +allow others the right to copy and use all the documents you create for it. +If you just mark a page as copyright, they won't even +legally be able to print it. +If you don't state you are its copyright owner, +they could change it slightly and claim it as their own property. +By marking it with both copyright and GPL notices +you allow them to copy it but not to claim +anything derived from it as their own. +

+The GPL protects your +JUNKBUSTERS DECLARATION, +Spam Offer, +and all documents from us that you publish on your home page +or distribute to direct marketers by any other means. +By making your +DECLARATION +available to them under the GPL, you are +permitting them use to it, but never to claim it as their property, +even if they transform it. +

<Feedback>  +Preamble +

+

+The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. +

+When we speak of free software, +we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. +

+To protect your rights, +we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. +

+For example, +if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. +

+We protect your rights with two steps: +(1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. +

+Also, +for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. +

+Finally, +any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. +

+The precise terms and conditions +for copying, distribution and +modification follow. +

+ +

<Feedback>  +GNU General Public License: Terms and Conditions for Copying, Distribution and Modification +

+

+O. +This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, +translation +is included without limitation in +the term "modification".) Each licensee is addressed as "you". +

+Activities +other than copying, distribution and modification are not covered by this License; +they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +

+Whether that is true depends on what the Program does. +

    +
  1. +You may copy +and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. +

    +You may charge a fee +for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. +

  2. +You may modify +your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: +
      +
    1. +You must cause +the modified files to carry prominent notices +stating that you changed the files and the date of any change. +
    2. +You must +cause any work that you distribute or publish, that in +whole or in part contains or is derived from the Program or any +part thereof, to be licensed as a whole at no charge to all third +parties under the terms of this License. +
    3. +If the modified program +normally reads commands interactively +when run, you must cause it, when started running for such +interactive use in the most ordinary way, to print or display an +announcement including an appropriate copyright notice and a +notice that there is no warranty (or else, saying that you provide +a warranty) and that users may redistribute the program under +these conditions, and telling the user how to view a copy of this +License. (Exception: if the Program itself is interactive but +does not normally print such an announcement, your work based on +the Program is not required to print an announcement.) +
    +

    +These requirements +apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. +

    +Thus, +it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. +

    +In addition, +mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. +

  3. +You may copy +and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: +
      +
    1. +Accompany it +with the complete corresponding machine-readable +source code, which must be distributed under the terms of Sections +1 and 2 above on a medium customarily used for software interchange; or, +
    2. +Accompany it with a written offer, +valid for at least three +years, to give any third party, for a charge no more than your +cost of physically performing source distribution, a complete +machine-readable copy of the corresponding source code, to be +distributed under the terms of Sections 1 and 2 above on a medium +customarily used for software interchange; or, +
    3. +Accompany it +with the information you received as to the offer +to distribute corresponding source code. (This alternative is +allowed only for noncommercial distribution and only if you +received the program in object code or executable form with such +an offer, in accord with Subsection b above.) +
    +

    +The source code +for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. +

    +If distribution of executable or object code is made +by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. +

  4. +You may not copy, +modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. +
  5. +You are not required +to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. +
  6. +Each time you redistribute +the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. +
  7. +If, as a consequence of a court judgment +or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. +

    +If any portion +of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. +

    +It is not the purpose +of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. +

    +This section +is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. +

  8. +If the distribution +and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. +
  9. +The Free Software Foundation +may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. +
  10. +If you wish to incorporate parts +of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. +

    +NO WARRANTY +

  11. +BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, +THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. +
  12. +IN NO EVENT UNLESS REQUIRED +BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. +
+END OF TERMS AND CONDITIONS +

+ +

<Feedback>  +Appendix: How to Apply These Terms to Your New Programs +

+

+If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. +

+To do so, +attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. +

+<one line +to give the program's name and a brief idea of what it +does.> +Copyright (C) 19yy +<name of +author> +

+This program is free software; +you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. +

+This program +is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the +GNU General Public License for more details. +

+You should +have received a copy of the GNU General Public License +along with this program; if not, write to the Free Software +Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. +

+

+Also add +information on how to contact you by electronic and paper mail. +

+If the program is interactive, +make it output a short notice like this +when it starts in an interactive mode: +

+Gnomovision version 69, Copyright (C) 19yy name of author +Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. +This is free software, and you are welcome to redistribute it +under certain conditions; type `show c' for details. +
+

+The hypothetical +commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. +

+You should also get your employer +(if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: +

+Yoyodyne, Inc., hereby disclaims all copyright interest in the program +`Gnomovision' (which makes passes at compilers) written by James Hacker. + +<signature +of +Ty Coon>, +1 April 1989 +
+Ty Coon, President of Vice +
+

+This General Public License +does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. +

For a list of the questions on this page (without the answers), +see our +Table of Contents. +It also contains detailed pointers into our pages +on +cookies +and on busting +junk e-mail, +junk mail +and +telemarketing calls. + +

<Feedback>  +What is the Internet Junkbuster Proxy and what does it do for me? +

+

+The +Internet Junkbuster +Proxy +TM +is +free +privacy-enhancing software that can be run on your PC or by your +ISP +or company. +It blocks requests for +URLs +(typically banner ads) +that match its +blockfile. +It also deletes unauthorized +cookies +and other +unwanted identifying +header information +that is exchanged between web servers and browsers. +These headers are not normally accessible to users +(even though they may contain information that's important to your privacy), +but with the +Internet Junkbuster +you can see almost +anything you want +and control everything you're likely to need. +You +decide what's junk. +SM +Many people +publish +their blockfiles to help others get started. +

+ +

<Feedback>  +Is there a license fee / warranty / registration form / expiration? +

+

+No, none of these. +It's completely free of charge. +Junkbusters +offers you the software to copy, use, modify and distribute +as you wish, forever, at +no charge +under the +GNU General Public License. +

+It comes with +no warranty of any kind. +

+You don't have to register, +in fact we don't even provide a way to do so: +the practice of registering software is +usually just an +excuse +to send you solicitations and +sell your name +and information about your behavior. +You are welcome to obtain and use our software as anonymously you wish. +(Your +IP +address will naturally be +disclosed +when you download it, +so if you work for a web ad company +you might want to use a service such as the +lpwa.com +when you get it. +We +never +want to be given any information that you consider private or confidential.) +

+We are often asked why we give away a product that many +would happily pay for. +The answer is that we are determined to carry out our +mission: +to free the world from junk communications. +

+ +

<Feedback>  +Does it run on Windows? On a Mac? On the AOL browser? +

+

+For the latest information on availability, see the +Distribution Information +page. +We +don't +think it will ever run on +Windows 3.1. +But you don't need to have it running on your computer +if you get your +ISP +or Systems Administrator at +work +to run it. +

+ +

<Feedback>  +How can I get my ISP to run the Internet Junkbuster? +

+

+Try their sales or support department +(depending on whether you are already a customer). +You might send them email including the following +URL: +
+   http://www.junkbusters.com/ht/en/ijbfaq.html#isps +
+You could mention that many +other +ISPs +provide it, +and that you regard it as an important part of your decision on +where to buy Internet service. +

+ +

<Feedback>  +Who chooses the options that control what is blocked? +

+

+Whoever starts the +Internet Junkbuster +chooses the options and the blockfile. +If your +ISP +runs it for you, they have to make these decision +(though +some +may give you a choice of proxies, +and a way to suggest new +URLs +to block). +If you run it on your computer, +You +decide what's junk. +SM +

+ +

<Feedback>  +How do I download and run the program on my computer? +

+

+It depends on your platform. +If you are using Windows 95 or NT, +see our separate page on +installing under Windows. +If you have a C compiler and are using almost any flavor of +UNIX ® +you +download it, compile it, start it running, +and then +configure your browser. +Several precompiled packages are also available through links in our +distribution page, +which lists all available platforms. +

+If you are using a platform for which we have no current +availability, +you are welcome to port the code. +If you do this and you would like us to consider publishing your ported version, +please +tell us. +

+ +

<Feedback>  +How can I tell which blockfile and options are being used? +

+

+Just point your browser to +http://internet.junkbuster.com/cgi-bin/show-proxy-args +or to any +URL +ending in +show-proxy-args +(even if it doesn't exist). +It needn't exist because the +Internet Junkbuster 2.0 +intercepts the request, blocks it, +and returns in its place +information about itself. +Using the +URL +above is useful for checking that your browser really is +going through an +Internet Junkbuster, +because the +junkbuster.com +server returns a warning if the request actually gets to it. +Some people set the home page of their browser to such a +URL +to be sure that it is configured to use the proxy. +

+If you wish to check the header information +your proxy is actually sending, +a visit to +http://internet.junkbuster.com/cgi-bin/show-http-headers +will give you the more relevant ones first. +You might also like to turn the proxy +off +and compare the difference. (Don't forget to turn it back on again.) +

+ +

<Feedback>  +My browser started giving me ``server not responding'' messages +

+

+Once your browser is told to use a proxy such as the +Internet Junkbuster, +it thinks of it as its server for everything, +so this message means it can't talk to the proxy. +The +Internet Junkbuster +may not be running, +or you may have specified its proxy +address +incorrectly. +Check that the details you entered are correct. +If you have +telnet +you can try connecting to the appropriate port to see if the +Internet Junkbuster +is running. +If your +ISP +is running the +Internet Junkbuster, +you may want to check with them. +If you are running it yourself under +UNIX ®, +try looking at a +ps ax +to see if it is running. +The +port +specified in its options should be the same one as your +browser has configured. +

+ +

<Feedback>  +I've got this great idea for a new feature. Who do I tell? +

+

+We'd be very interested to hear it, but please bear a few things in mind. +

+

+ +

<Feedback>  +My question isn't listed here. Who do I ask for support? +

+

+If you find using our free product +harder than you're used to for consumer software, +there are many +commercial alternatives +that you could consider. +

+The answer to detailed technical questions may be answered in +manual page, +or in the source code. +Also double-check this page for an answer: +using the ``find'' feature on your browser for likely keywords may help. +Our site also has a +search +feature. +

+Many people post requests for help and responses on +Usenet. +

+If your +ISP +is providing +the +Internet Junkbuster +for you, +and your question is about how to use it, +check their web page before asking them. +

+Even though we don't offer the kind of +support you might expect if you paid a lot of money for a software product, +you can still ask us. +But before you do, please consider whether +you could ask someone closer to you. +And please be patient if we're slow to reply: we +never charge consumers +for our services, +so we have to subsidize consumers with revenue from companies, +and our resources are limited. +

+If your company or organization +would be interested in a maintenance contract +with phone and email support, +hard copy documentation and source code and pre-compiled binaries on tape +or disk, +please +ask us +for a quote. +

+

+Configuring your browser to talk to the Internet Junkbuster + +

+
+
+

<Feedback>  +What is the proxy address of the Internet Junkbuster? +

+

+If you set up +the +Internet Junkbuster +to run on the computer you browse from +(rather than your +ISP's server +or some networked computer at work), +the proxy will be on +localhost +(which is the special name used by every computer on the Internet to +refer to itself) +and +the port will be +8000 +(unless you have told the +Internet Junkbuster +to +run on a different port with the +listen-address +option). +So you when +configuring your browser's proxy settings +you typically enter the word +localhost +in the two boxes next to + +HTTP +and + +Secure, +and the number +8000 +in the two boxes labelled +to the right of those boxes. +

+If your +ISP +or company is running +the +Internet Junkbuster +for you, +they will tell you the address to use. +It will be the name of the computer it's running on +(or possibly its numeric IP address), +plus a port number. +Port 8000 is the default, so assume this number if it is not specified. +Sometimes a colon is used to glue them together, +as in +junkbuster.fictitous-pro-privacy-isp.net:8000 +but +with most browsers +you do not type the colon, +you enter the address and port number in separate boxes. +

+ +

<Feedback>  +How do I tell the browser where to find the Internet Junkbuster? +

+

+All current browsers can be told the address of a proxy to use. +You enter the same information in two fields in your browser's proxy +configuration screen (see list below): one for +HTTP, +and one for the Secure Protocol (assuming your browser supports +SSL). +If you find some information already entered for your proxy, +see the +next question. +Here are the menus you go through to get to the proxy configuration settings. +(We also recommend that you +disable Java, +which is a separate operation.) +Make notes on the changes you make so you know how to undo them! +You will need to know what you did +in case you wish to +discontinue +using the proxy. +

    +
  • +For +Netscape +2.01, 2.02 and 3.0 +[Graphic Illustration]: + +Options; + +Network Preferences; + +Proxies; + +Manual Proxy Configuration View ; +enter +proxy address details +under + +HTTP +and + +Security Proxy; +click on + +OK; +click on the next + +OK. +
    +With Netscape 2.0, +follow with + +Options, + +Save Options. +
    +With Netscape 4.X series, you first have to go through + +Edit/Preferences. +[Graphic Illustration] +Then in the frame on the left, +click on triangle pointing to the right towards the word + +Advanced; +it will switch to a triangle pointing down; +and the words + +Cache, + +Proxies +and + +Disk Space +appear. +Click on + +Proxies +and the frame on the right will +display a banner saying + +Proxies Configure proxies to access the Internet. +Click the radio button labeled + +Manual proxy configuration +then click the button labeled + +View; +enter +proxy address details +under + +HTTP +and + +Security Proxy; +click on + +OK; +click on the next + +OK. +
  • +For +Internet Explorer 3.0: + +View; + +Options; + +Connections; +tick + +Connect through proxy server +box; + +Settings; +enter +proxy address details + +HTTP +Box, with port number in the second box; +same with + +Secure; +click on + +OK. +
  • +For Internet Explorer 2.0: + +View; + +Options; + +Proxy; +enter +proxy address details +click on + +OK. +
  • +On NT for MS-IE: + +Control Panel; + +Internet; + +Advanced; + +Proxy. +
  • +For MS-IE 4.0: seems to be almost the same as for +3.0, + +View; + +Internet Options; + +Connections; +tick + +Connect through proxy server +box; + +Settings; +enter +proxy address details + +HTTP +Box, with port number in the second box; +same with + +Secure; +click on + +OK. +Note that 4.0 has + +Advanced +settings to allow +HTTP +1.1 through proxies; +these must be disabled because the proxy does not currently understand +HTTP +1.1. +Please +tell us +if you see any other differences. +
  • +For NCSA Mosaic for Windows: + +Options, + +Preferences, + +Proxy; +enter +proxy address details +under + +HTTP. +
  • +For +Opera: + +Preferences, + +Proxy servers; +check the box next to HTTP; +enter the server and port number in the box on the other side; +click on + +OK. +
  • +For +Lynx, +Mosaic/X, +Grail, +and +W3O +Arena, +you can specify the proxy via environment variables +before starting the application. +This will probably be done with something like either +
    +   setenv http_proxy http://localhost:8000/ +
    +or +
    +   http_proxy=http://junkbuster.fictitous-pro-privacy-isp.net:8000/ export http_proxy +
    +depending on your shell and where the +Internet Junkbuster +lives. +
+If your browser is not listed here, +or if you notice an error, please +tell us +the correct procedure. +

+ +

<Feedback>  +What should I do if I find another proxy is already configured? +

+

+Some +ISPs +and companies require all Web traffic to go through their proxy. +In this case you would find your proxy configuration with values already set, +possibly under +Automatic Proxy Configuration +(in the case of +Netscape +and +MS-IE 3.0 +and above). +It's probably a firewall proxy between your company and the outside world, +or a +caching proxy +if you're using an +ISP. +

+What needs to be done in this case is to +use the +forwardfile +option +to tell the +Internet Junkbuster +the address of the other proxy. +Specify a different (unused) port number +with the +listen-address +option, +and configure your browser to +use that port. +If you haven't done this kind of thing before, +it's probably best to consult your systems administrator or +ISP +about it; +check their web page first. +

+ +

<Feedback>  +What if I want to stop using the Internet Junkbuster? +

+

+Just go through the same procedure you used to start your +browser using the +Internet Junkbuster, +but remove the details you put in +(or if there was something there before, restore it). +You may need to use + +Save Options +to make this change permanent. +On Netscape 3.0 you can go through + +Options; + +Network Preferences; + +Proxies +and click on + +No Proxy +to turn it off, and later click on + +Manual Proxy Configuration +if you want to start using it again. +(No need to enter the again details under + +View +as you did the +first time; +they should remain there unchanged.) +

+This stops your browser talking to the proxy; +shutting down the proxy +is a different matter. +

+ +

<Feedback>  +Automatic dialing isn't working any more. How do I fix it? +

+

+Some browsers (such as MSIE-4) can be configured to dial your +ISP +automatically when you click on a link, +but this feature gets disabled if you specify a proxy running on your +own computer +(with address +localhost +or +127.0.0.1) +because these addresses don't require dialing. +The +Internet Junkbuster +knows nothing about dialing, so it doesn't work. +To make automatic dialing work, +make up a name such as +junkbuster.ijb +and use that name in the proxy settings +instead of +localhost, +and then add the line +127.0.0.1 junkbuster.ijb +to the file +c:\windows\hosts +(if there already is a line beginning with +127.0.0.1 +just add +junkbuster.ijb +at the end of it.) +

+This should also work Netscape Communicator 4 on +machines where IE-4 has been installed. +

+
The next two sections assume you wish to compile the code +with your own C compiler. +If you just want to use the +.exe +file provided for Windows, +see the +Windows Installation page. + +

<Feedback>  +How do I compile the code under Unix? +

+

+If you are running Redhat +Linux +you may prefer to use the +rpm +instead of the following procedure. +

    +
  1. +First +download the tar file +(~286k) +and +uncompress and extract the files from it with this command +
    +   uncompress -c ijb20.tar.Z | tar xf - +

    +

  2. +If your operating system is from +Sun +or +HP +examine the +Makefile +and make any changes indicated inside. +
  3. +Run +
    +
    +   make +

    +

  4. +Copy the sample configuration file +(junkbstr.ini, +previously called +sconfig.txt +and other names in earlier releases) +to some convenient place such as +/usr/local/lib/junkbuster/configfile +or whatever you choose. +The sample file has all the options commented out. +You can remove the +# +character on any that you want, but it may be better to +leave this until to later. +Run it asynchronously: +
    +
    +   junkbuster configfile & +

    +If you are running a version earlier than 2.0 you can start it with +junkbuster & +

    +

  5. +Configure your browser (described +above). +
  6. +Verify that the +Internet Junkbuster +is working (described +above). +
  7. +Decide on the options you really want, +kill +the +process +and start it again. The most popular option is +blockfile +to block ads. +A sample blockfile is provided as an illustration, +but it doesn't really stop many ads. +More comprehensive ones are available +elsewhere. +
  8. +You'll probably want to add an entry to +/etc/rc.d/rc.local +or equivalent to start it at boot time. +(Any output you specify should be redirected to a file. +And don't forget the +& +at the end to run it asynchronously or your system will seize +up after the next reboot.) +
+

+ +

<Feedback>  +How do I compile the code under Windows? +

+

+A binary is currently being supplied with the source code, +but if you prefer to compile it yourself here is the likely procedure. +Most of these steps are repeated in our checklist for +installation under Windows. +

    +
  1. +First +click here to download the zip file +called +ijb20.zip +(~208k), +then uncompress and unpack the zip archive using a tool like +WinZip. +
  2. +Now the distribution (source and sample files) +will be in a folder +called +ijb20. +Go into that folder and then edit the Makefile for +your system, +removing the comment character +(#) +in the lines related to Win32. +Then type: +
    +   nmake +
    +This should create an executable called +junkbstr.exe. +For information on issues with various compilers, see the +Distribution Information +page. +
  3. +Run the executable with the command: +
    +   junkbstr +
    +The program will produce a message +indicating that it has started and is ready to serve. +

    +(Version 2.0.1 and above uses +the file +junkbstr.ini +as the config file +if it exists and no argument was given. If you have an earlier +version or if you want it to use a different config file, +simply specify that file as the argument.) +

  4. +Configure your browser (described +above). +
  5. +Check the proxy is working (described +below). +
  6. +To have the proxy start itself automatically +when you login to Win95, +drop the ``shortcut'' to the +junkbstr +executable into the StartUp folder: +
    +   C:\Windows\Start Menu\Programs\StartUp +
    +You might want to change the shortcut's +Properties->Shortcut +to +Run: Minimized. +If you specify the +hide-console +option then the +DOS +window will vanish after it starts. +

    +WinNT users can put it into their own +StartUp folders or the Administrator +can put it into the system's global StartUp folder. +For details on how to make this a service under NT +see our +Windows page. +

+

+ +

<Feedback>  +How do I check that the proxy is working? +

+

+Pick a page from somewhere (such as your bookmarks, or just one +that your browser was pointing to) +and + +Reload +it. +If you get a message along the lines of ``server not responding, +using cached copy instead,'' see the advice +above. +If the page reloads OK, check that your browser is actually +talking to the proxy by going to +http://internet.junkbuster.com/cgi-bin/show-proxy-args +or any +URL +ending in +show-proxy-args +(as described +below, +the proxy should intercept the request.) +When you see ``Internet Junkbuster Proxy Status,'' +you'll know it's working. +

+ +

<Feedback>  +How and why would I have this proxy chained with other proxies? +

+

+You may need the +forwarding +feature to ``daisy chain'' the +Internet Junkbuster +to another proxy, perhaps an +anonymizing +proxy to +conceal +your +IP +address, +or a +caching proxy +from your +ISP, +or a +firewall +proxy between your company and the outside world. +Version 2.0 +can be even configured to forward +selectively +according to the +URL +requested: +for example, connecting directly to trusted hosts, +but going through an anonymizing or firewall proxy for all other hosts. +

+Network administrators might use it to provide +transparent access to multiple networks without +modifying browser configurations. +Most browsers also provide a way of +specifying hosts that the browser +connects to directly, bypassing the proxy. Some provide a method for +Automatic Proxy Configuration. +A well written +Internet Junkbuster +configuration can be much more flexible and powerful. +

+An +ISP's +caching proxy +would typically be called something like +cache.your-isp.net:8080 +(as described on you +ISP's +web page); +you would put this information in your +forwardfile +as described in our manual. +Your browser would be configured to +the +Internet Junkbuster +for +HTTP +and Security Proxies as before, +but you probably want to tell it to use the caching proxy +for +FTP +and other protocols. +If your +ISP +is running +the +Internet Junkbuster +for you, +they have probably already decided whether to chain with a caching proxy. +

+ +

<Feedback>  +How does the Internet Junkbuster work with SOCKS gateways? +

+

+There is support for some +gateways +in +Version 1.4 +and above. +The gateway protocol used to be specified on the command line; +it is +now specified +in the same file as +forwarding. +Note that the browser's proxy configuration must +not +specify a +SOCKS +host; +it should specify the proxy as described +above. +

+ +

<Feedback>  +How do I configure it to be just a plain old proxy? +

+

+To get the proxy to do as little as possible (which means not deleting any +sensitive headers), place in your +configuration file the following three lines (each ending in a space +then a period) to stop it changing sensitive headers: +
+   referer . +
+   from . +
+   user-agent . +
+   cookiefile mycookiefile +
+The fourth line is also needed to specify a +cookiefile +that might be called +mycookiefile +containing a single line with a +* +character, to allow all cookies through. +

+ +

<Feedback>  +How do I shut down the proxy (to restart it)? +

+

+It depends on your platform. Under Windows, use + +Ctrl-Break +in the +DOS +window or +the old three-fingered salute of + +Ctrl-Alt-Delete +and select + +End Task. +Under +UNIX ® +you'll need to +kill +the +junkbuster +process. +If you don't know the process number to give to +kill, try this: +ps ax | grep junkbuster +

+Information for companies + +

+
+
+

<Feedback>  +What do advertising companies think of this kind of technology? +

+

+We've seen only a few public comments from the advertising industry on this, +other than +SEC filings. +First, the president of the Internet Advertising Bureau told +CNET +that he wasn't worried by banner blockers. +Second, after the Federal Trade Commission's +workshop +where we gave a live demonstration of our proxy before +many eminent representatives of the industry, +the +Direct Marketing Association +made the following +statement in the closing paragraphs +of their +summary comments +to the Commission. +

+Clever shareware developers have come up with products that +can obliterate cookies and advertisements for those consumers +who have these concerns. +The Internet is a market that is so democratic and flexible +that it is easy for companies and software +developers to respond to a perceived market need. +
+Their attitude seems to be that they would prefer that +people use technical solutions +to protect their privacy than have protections +imposed by legislation or government regulations. +So, do you perceive a market need? +Then here are some ways to flex your democratic muscles. +

+ +

<Feedback>  +Should we provide the Internet Junkbuster for our employees? +

+

+That depends. Try this quick three-point test. +

    +
  1. +Do you want to spend your communications budget +on bandwidth that wastes your employees' time by forcing them to wait +for a lot of annoying distractions while they're trying to +do their jobs? +
  2. +Do you want current and potential vendors +to know quantitative details about the +software and hardware platforms +that you have? +
  3. +Do you want your competitors to be able to +track +exactly which of your +employees are checking out their web sites? +
+If the answer to all three questions is yes, +then you probably don't have any need for this kind of product. +

+ +

<Feedback>  +Can our company get commercial support for the software? +

+

+Yes, +ask us +for a quote on a maintenance contract with your choice of +phone and email support, +hard copy documentation, +source code and pre-compiled binaries on tape or disk, +and email alerting of upgrades and issues. +We also offer consulting services to help set up ``stealth browsing'' +capabilities to help reduce the footprints left while doing competitive +analysis and other Web work where confidentiality is critical. +

+ +

<Feedback>  +I run an ISP. What issues should I consider before offering it? +

+

+Many +ISPs +who offer the proxy to their customers have told us that +most of their customers are +delighted with it +(although one reported that a customer complaint that without banner ads, +surfing was like reading a novel: we recommend making it optional). +Many +ISPs +like it because it reduces bandwidth requirements. +To help get you started, +here's a checklist we've developed from working with a few +ISPs. +You may think of more, +and we'd be interested if you're willing to +share them +with us. +

    +
  1. +If you get more than one request for +the +Internet Junkbuster +you may want to tell your customers on your News page that you +already +know about it and are assessing it. +
  2. +Try the software and +verify +that it performs satisfactorily. +
  3. +Determine whether your customers perceive the service as +valuable +(and therefore worth the time to set up). +We've had reports of many delighted customers. +
  4. +Assess the +level of +security +associated with the software. +If access is to be +restricted +(to just dial-in ports, for example) +how is this to be done? +
  5. +Consider +whether to expect any additional load on computing resources required, +and any change in use of bandwidth due to the blocking of large +GIFs. +
  6. +Choose the +options +you wish to provide. +
  7. +Decide whether you want +to offer a choice of configurations, such some of these four. +
      +
    1. +Banners +Blocked, +Wafer with +No-Cookie-Copyright +notice +
    2. +Cookies +not stopped +(cookiefile +with just a +* +in it), +User Agent +specified as +Lynx +
    3. +Cookies from browser +allowed, +permitting +registered services +
    4. +A proxy for +kids. +
    +If you run a +caching proxy, +decide whether the +Internet Junkbuster +will chain with it by default, +and whether to offer an alternate with no caching. +(Some +ISPs +don't, because they want to give customers an incentive to use caching +and save bandwidth.) +
  8. +Decide on a naming scheme for your +proxies. +If you're running only one +proxy on one machine, +the simplest way is to just use port 8000 on your main machine, +such as +our-isp.net. +But it would probably be safer to put an entry in your name server +and call it something like +junkbuster.our-isp.net. +If running several proxies, you could either use different ports +on the same machine, or if you have +the opportunity to distribute the load over +a few machines +you could +use different hostname aliases such as +banner.junkbuster.our-isp.net, +lynx.junkbuster.our-isp.net +and +oneway.junkbuster.our-isp.net +(corresponding to the examples in the previous point). +You may want to set up +Automatic Proxy Configuration. +
  9. +Prepare a page +explaining the +Internet Junkbuster +to your customers. +Here's are some examples from +Australia, +Germany, +Florida, +New York/New Jersey/Pennsylvania, +North Carolina, +Texas, +and +Utah. +You are welcome to copy and modify +material +from +Junkbusters +according to the +GPL. +You might want to set up a process to check this page periodically +and update it when it changes. +(A few links can probably serve as well as lot of copying however.) +A typical page would probably specify the following. +
    +
  10. +Invite a small number of technologically sophisticated +customers to beta-test the service. +
  11. +Announce general availability on your ``News'' page. +Tell us +if you would like to be included on a list of +ISPs +offering the +Internet Junkbuster. +
+

+ +

<Feedback>  +What's a Proxy Server Server and how can I make money as one? +

+

+Other organizations with web presence and some bandwidth to spare +can set up as +Proxy Server Servers + +(PS2s). +The idea here is to allow users to choose their proxy configuration, +and provide it to them on a semi-permanent basis. +Users would fill in a form specifying what options they want in +their proxy, +possibly even at a very high level, such as +``no ads'' +or ``no nudity.'' +This information is sent to a +CGI +script that +configures a proxy, starts it running, and returns its address and port number +(possibly along with configuration instructions for the browser +that the user specified.) +

+Users +could be charged +a subscription fee, +or the service could be thrown in free in the hope of +improving customer retention for some existing business +(which is what +ISPs +are doing). +It might be possible to make money by +inserting new ads in the holes left where others were blocked, +but the original owners might object. +PS2s +could differentiate themselves +by providing frequently updated and comprehensive +blocking of ads, or of offensive material based on their own grading system. +Some content providers might do it for the chance to be the +only company that the consumer permits to set cookies. +(Identification could even be done via cookies, +but this might not be popular with the kind of user who wants a proxy.) +PS2s +might sell specific or aggregate information about their +users' browsing habits, +so the agreement with users on whether they are permitted to do this +would be important to both sides. +

+If your organization +establishes a +Proxy Server Service +you would like publicized, +please +notify us. +

+Blocking + +

+
+
+

<Feedback>  +Where can I get an example blockfile that stops most ads? +

+

+The sample blockfile we provide blocks almost nothing, +and we do not publish blockfiles that stop almost all banner ads. +But others have; you can find them by +asking Altavista. +You can add any part of the new file to your old one +(probably called +sblock.ini +if you haven't changed the default name in the latest version) +or your just replace it completely. +You +probably +don't need to restart the proxy. +

+If you develop an interesting blocklist and publish it on the Web, +you might want to include the word ``junkbuster'' in it +and use the word ``blocklist'' in the file name given in the +URL +so that others can find it with the query given in the previous sentence. +

+ +

<Feedback>  +If I see an ad I wish I hadn't, how do I stop it? +

+

+If your +ISP +is running the +Internet Junkbuster, +they should have a policy on whether they accept suggestions from +their customers on what to block. Consult their web page. +

+If you are running +the +Internet Junkbuster +yourself, you have complete control over what gets through. +Just add a pattern to cover the offending +URL +to your blockfile. +Version 1.3 and later automatically rereads the blockfile when it changes, +but if you're running an earlier version you'll +have to +stop it +and restart it. +

+To choose a pattern you'll first need to find the +URL +of the ad you want cover. +

+Some people use the +debug +1 +option to display each +URL +in a window as the request is sent to the server. +It's then usually an easy task to pick the offending +URL +from the list of recent candidates. +

+Alternatively, +you can use + +View Document Info +(or + +View Document Source +if your browser doesn't have that). +The + +Info +feature has the advantage of showing you the full +URL +including the host name, +which may not be specified in the source: +there you might see something like +SRC="/ads/click_here_or_die.gif" +indicating only the +path. +(The host name is assumed to be the same as the one the page came from.) +

+But ads often +come from a different site, in which case you +might see something like +SRC="grabem.n.trackem.com/Ad/Infinitum/SpaceID=1666" +or longer. +If the company looks like a pure ad warehouse +(as in the last case), +you may want to place just its domain name in the blockfile, +which blocks all +URLs +from that site. +

+If the ad comes from a server +that you really want some content from, +you can include enough of the path +to avoid zapping stuff you might want. +In the first example above, +/ads/ +would seem to be enough. +If you don't include the domain name, +the pattern applies to all sites, +so you don't want such patterns +to be too general: +for example +/ad +would block +/admin/salaries/ +on your company's internal site. +

+To speed the blocking of images, some +UNIX ® +users create a +shell script called +Image: +containing a line such as +echo $1 | sed s/http:..// >> $HOME/lib/blockfile +that adds its argument to the user's blockfile. +Once an offending image has been be found using + +View Document Info +it's easy to cut-and-paste the line (or part of it) into a shell window. +The same script can be linked to a file called +Frame: +to dealing with framed documents, +and +junkbuster: +to accept the output of the +debug +option. +

+When compiled without the +regular expressions +option, the +Internet Junkbuster +uses only very simple (and fast) matching methods. +The pattern +/banners +will not stop +/images/banners/huge.gif +getting through: you would have to include the pattern +/images/banners +or something that matches in full from the left. +So you can get what you want here, +the matcher understands +POSIX +regular expressions: +you can use +/*.*/banners +to block +and any +URL +containing +/banners +(even in the middle of the path). +(In Versions 1.1 through 1.4 +they were an option at compile time; +from Version 2.0 they have become the default.) +Regular expressions give you +many more features +than this, +but if you're not already familiar with them you probably won't +need to know anything beyond the +/*.*/ +idiom. +If you do, a +man egrep +is probably a good starting point). +

+Don't forget the +/ +(slash) +at the beginning of the path. +If you leave it out the line will be interpreted as a domain name, +so +ad +would block all sites from Andorra +(since +.ad +is the two-letter +country code +for that principality). +

+For a detailed technical description +of how pattern matching is done, +see the +manual. +

+ +

<Feedback>  +How come this ad is still getting through anyway? +

+

+If the ad had been displayed before you included its +URL +in the blockfile, +it will probably be held in cache for some time, +so it will be displayed without the need for any request to the server. +Using the +debug +1 +option to show each +URL +as it is fetched is a good way to see exactly what is happening. +

+If new items seem to be getting through, +check that you are +really running +the proxy with the right blockfile in the options. +Check the blockfile for +exceptions. +

+Some sites may have different ways of inserting ads, +such as via +Java. +If you have ideas on how to block new kinds +of junk not currently covered, please +tell us. +

+ +

<Feedback>  +How do I stop it blocking a URL that I actually want? +

+

+You can change the patterns so they don't cover it, +or use a simple feature in Version 1.1 and later: a line beginning with a +~ +character means that a +URL +blocked by previous patterns that matches the rest of +the line is let through. +For example, +the pattern +/ad +would block +/addasite.html +but not if followed by +~/addasite +in the blockfile. +Or suppose you want to see everything that comes from +a site you like, even if it looks like an ad: simply put +~aSiteYouLike.com +at the +end +of the blockfile. +(Order is important, because the last matching line wins.) +

+As well as unblocking +pages that were unintentionally blocked, +this feature is useful for unblocking ads from a specific source. +This might be because you are interested in those particular ones, +or if you have an explicit agreement to accept certain ads, +such as those from a free web-based email provider. +

+ +

<Feedback>  +Can I block sites I don't want my children to see? +

+

+Yes, but remember that +children who are technically sophisticated enough +to use the browsers' proxy configuration options +could of course bypass any proxy. +This kind of technology can be used as a gentle barrier to remind +or guide the child, +but nobody should expect it to replace the parent's role +in setting and enforcing standards of online behavior for their children. +

+Some +ISPs +are starting to provide specialized proxies to protect children. +There are two basic approaches: the ``black list'' and the ``white list'' +approach. +The black list approach allows the child +to go anywhere not explicitly prohibited; the white list permits visits +only to sites explicitly designated as acceptable. +

+It's very easy for +anyone to +compile a white list from a page of ``recommended +kids sites'' and to configure an +Internet Junkbuster +to allow access to those sites only. +If you compile with the +regex +option, +you can place a +* +(asterisk) as the first line of the blockfile (which blocks everything), +and then list +exceptions +after that. +Be careful to make the exception sufficiently broad: +for example, using +~www.uexpress.com/ups/comics/ch/ +as the exception for +Calvin and Hobbes +would block some of the graphic elements on the page; +you would probably want a wider exception such as +~www.uexpress.com/ups/ +to permit them. +

+Version 2.0 has an experimental feature +to permit only sites mentioned in a nominated +trusted site. +This allows organizations to build lists of sites for kids to browse, +and the software automatically restricts access to those on the list. +

+Many filtering +products +actually scan for keywords in +the text of pages they retrieve +before presenting it, +but +the +Internet Junkbuster +does not do this. +Building a perfectly reliable black list system is hard, +because it's very difficult to state +in advance +exactly +what is obscene or unsuitable. +For more info see our +links +page. +

+ +

<Feedback>  +What do I see when a page or graphic is blocked by the proxy? +

+

+You usually see a broken image icon, +but it depends on several factors beyond the proxy's control. +If asked for a +URL +matching its blockfile, the proxy returns an +HTML +page containing a message identifying itself +(currently the two words ``Internet Junkbuster'') +with a status 202 (Accepted) instead of the usual 200 (OK). +(Versions 1.X returned an error 404: Forbidden, which caused +strange behavior in some cases.) +Status 202 is described in the +HTTP +RFC +as indicating that the request has been accepted but not completed, +and that it might complete successfully in the future +(in our case, if the blockfile were changed). +

+The broken image icon is most common +because the browser is usually expecting a graphic. +But if it was expecting text, or if the page happens to be using certain +HTML +extensions +such as +layer +and your browser is a late model from Microsoft, +you may see the words ``Internet Junkbuster'' displayed as a hot link. +

+Clicking on the link takes you to an explanation of +the pattern in the blockfile that caused the block, +so that you can edit the blockfile and go back and reload if you really +want to see what was blocked. The explanatory link is generated by +the proxy and is automatically intercepted based on its ending in +ij-blocked-url; +even though the site is specified as +http://internet.junkbuster.com +no request should actually made to that site. +If one is, it means that the proxy was been removed after it +generated the link. +

+To summarize: +the identifying link to the blocking explanation +is usually turned into a broken image icon, +but it may be displayed on a page alone, +or they may may be restricted to the particular frame, layer or graphic area +specified in the page containing them. +The proxy has no way of knowing the context in which a +URL +will be used and cannot control how the blocking message will be rendered. +

+ +

<Feedback>  +Why not replace blocked banners with something invisible? +

+

+Many users have suggested to us +that blocked banners should be replaced by a something like a +1x1 transparent +GIF +to make the page would look as if there was nothing ever there. +Apart from making it harder to catch unintended blocking, +this might also displease the owners of the page, +who could argue that such a change constitutes a copyright infringement. +We think that merely failing to allow an included graphic to be accessed +would probably not be considered an infringement: +after all this is what happens when a browser +is configured not to load images automatically. +However, we are +not +lawyers, +so anyone in doubt should take appropriate advice. +

+In a context where the copyright issue is resolved +satisfactorily, +a proxy could simply return a status 301 or 302 and +specify a replacement +URL +in a +Location +and/or +URI +header. +An alternative would be to use inline code to return a +1 x 1 clear +GIF. +We do not publish sample code for this, +and we have no way of stopping +others +who have. +

+ +

<Feedback>  +Why not block banners based on the dimensions of the image? +

+

+Many users have pointed out that most banner ads come in standard sizes, +so why not block all +GIFs +of those sizes? +This would theoretically be without fetching the object +because the dimensions are usually given in the +IMG +tag, +but it would require substantial changes in the code, +and we doubt whether it would be much more effective than a good block list. +

+ +

<Feedback>  +What about non-graphic advertising within the pages I want? +

+

+The +Internet Junkbuster +deliberately +does not provide a way of automatically editing the contents of a page, +to remove textual advertising or +to repair the holes left by blocked banners. +Other packages such as +WebFilter +do. +

+For the same reason, +it has no way of stopping a new browser +window being created, because this is done through the +target +attribute in the +<a> +and +<base> +elements, +not through headers. +Nor do we plan to add a feature to +paralyze animated +GIFs. +

+ +

<Feedback>  +Does it block ads on the broadcasting ``push'' systems? How about pop-up ads? +

+

+We haven't tried it but we expect it would probably +work on image ads on push channels. +See also +adchoice. +

+Disabling +Javascript +stops some pop-up ads. +One problem is that some advertisers throw open a new +browser window to frame the ad. The ad is easily blocked, +but the empty window remains. You can kill it easily, but this is a chore. +We don't see how to stop them other than editing the +HTML +from the parent window, which we +don't +like to do. +

+The +TBTF +newsletter warned subscribers to push information that +in IE4, +LOGTARGET +allows +servers to determine the +URLs +viewed at their site even if accessed from cache or through a proxy. +If you use this browser see our instructions on +how to disable +this. +

+If you find you have experience using the proxy with push, +or have any other advice about it, please +tell us. +

+Cookies + +

+
+
For background information on cookies see our +page describing their dangers. + +

<Feedback>  +Might some cookies still get through? How can I stop them? +

+

+Yes, you should expect the occasional cookie to make it through to your browser. +We know of at least three ways this can happen; +please +tell us +if you find any others. +One way is in secure documents, which are explained +below. +

+A +few +sites set cookies using a line such as +<META HTTP-EQUIV="Set-Cookie" CONTENT="flavor=chocolate"> +in the +HEAD +section of an +HTML +document. +Cookies can also be + +set and read +in +JavaScript. +To see if this is happening in a document, +view its source, look in the +head +for a section tagged +script language="JavaScript". +If it contains a reference to +document.cookie, +the page can manipulate your cookie file without sending any cookie headers. +The +Internet Junkbuster +does not tamper with these methods. +Fortunately they are rarely used at the moment. +If a cookie gets set, it should be stopped +by the proxy on its way back to the server when a page is requested, +but it can still be read in Javascript. +bu +

+To prevent cookies breaking through, +always +keep +cookie alerts +turned on in your browser, +and +disable +Java and Javascript. +Making the files +hard to write +may also help. +

+ +

<Feedback>  +Exactly how do cookies get created and stored anyway? +

+

+When a web site's server sends you a page it also sends +certain ``header information'' which your browser records but does not display. +One of these is a +Set-Cookie +header, which specifies the cookie information that the server wants your browser to record. +Similarly, when your browser requests a page it also sends headers, specifying +information such as the graphics formats it understands. +If a cookie has previously been set by a site that matches the +URL +it is about to request, +your browser adds a +Cookie +header quoting the previous information. +

+For more background information on how cookies +can damage your privacy, see our +page on cookies. +For highly detailed technical information see the +RFC. +The +Internet Junkbuster +will show you all headers you use the +debug +8 +option, +or you can get a sample from our +demonstration page. +

+ +

<Feedback>  +If cookies can't get through, will some things stop working for me? +

+

+Possibly. +Some personalized services including certain + +chat +rooms +require cookies. +Newspapers that require + +registration +or + +subscription +will not automatically recognize you if you don't send them the cookie they +assigned you. And there are a very small number of sites that do +strange things with cookies; they don't work for anyone that blocks +cookies by any means. +Some sites such as +Microsoft +explain that their content is so wonderfully compelling that +they will withhold it from you unless you submit to their +inserting cookies. +

+If you want such sites to be given your cookies, +you can use the +cookiefile +option provided you are running +Version 1.2 or later +yourself. +Simply include the domain name of those sites in the +cookiefile +specified by this option. +If it still doesn't work, +the problem may be in +other headers. +

+It's possible to let cookies out but not in, +which is enough to keep some sites happy, but not all of them: +one newspaper site seems to go into an endless frenzy +if deprived of fresh cookies. +A cookiefile containing +a single line consisting of the two characters +>* +(greater-than and star) permits server-bound cookies only. +The +* +is a +wildcard +that matches all domains. +

+If someone else is running the +Internet Junkbuster +for you and has a version +that + +passes server-bound cookies through, +you can try editing your browser's cookie +file to contain just the ones you want, +and restart your browser. +To subscribe to a new service like this +after you have started using the +Internet Junkbuster, +you can try the following: +tell your browser to +stop using +the +Internet Junkbuster, +fill out and submit your subscription details +(allowing that web site to set a cookie), +then +reconfigure your browser to use the +Internet Junkbuster +again +(and stop more cookies being sent). +This also requires the +cookiefile +option, +and its success depends on the Web site +not wanting to change your cookies at every session. +For this reason it does not work at some major newspaper sites, for example. +But you may prefer to +look at whether other sites provide the same +or better services without demanding the opportunity +to track your behavior. +The web is a buyer's market where most prices are zero: +very few people pay +for content with money, so why should you pay with your privacy? +

+ +

<Feedback>  +Can I control cookies on a per-site basis? +

+

+Yes, since version 1.2 the +Internet Junkbuster +has included advanced cookie management facilities. +Unless you specify otherwise, +cookies are discarded (``crumbled'') by the +Internet Junkbuster +whether they came from the server or the browser. +In Version 1.2 and later you can +use the +cookiefile +option +to specify when cookies are to be passed through intact. +It uses the same syntax and +matching +algorithm as the blockfile. +

+If the +URL +matches a pattern in the +cookiefile +then cookies are let through in both the browser's request for the +URL +and in the server's response. +One-way permissions can be +specified by starting the line with the +> +or +< +character. +For example, a cookiefile consisting of the four lines +
+   org +
+   >send-user-cookies.org +
+   <accept-server-cookies.org +
+   ~block-all-cookies.org +
+allows cookies to and from +.org +domains only, with the following exceptions: +

    +
  1. +Cookies sent from servers in the domain +send-user-cookies.org +are blocked on their way to the client, +but cookies sent by the browser to that domain are still be fed to them. +
  2. +The cookies of +accept-server-cookies.org +check in to the proxy and are passed through to the browser, +but when they come back to the proxy they never check out. +
  3. +All cookies to and from +block-all-cookies.org +are blocked. +
+

+If +the +junkbuster +was compiled with the regular expressions option +they may be used in paths. +Any logging to a +``cookie jar'' +is separate and not affected. +

+It's important to give hosts you want to be able +to set cookies sufficient breadth. For example, +instead of +www.yahoo.com +use +yahoo.com +because the company uses many different hosts ending in that domain. +

+ +

<Feedback>  +Can I make up my own fake cookies (wafers) to feed to servers? +

+

+Yes, +using the +wafer +option. +We coined the term +wafer +to describe cookies chosen by a user, +not the Web server. +Servers may not find wafers as tasty as the cookies +they make themselves. +But users may enjoy controlling servers' diets for various reasons, +such as the following. +

    +
  • +Users who consider cookies to +be an unwelcome intrusion and a waste +of their disk space can respond in kind. +By writing ``signature wafers'' they can +express their feelings about cookies, +in a place that the people +in charge of them are most likely to notice. +
  • +Sites running a proxy +that logs cookies to a file +(such as the +Internet Junkbuster +does with the +jarfile +option on) +may want to notify +servers that their cookies are being intercepted, +deleted or copied. +One possible reason for doing this is the uncertain copyright status +of cookie strings. +Nothing +here should be taken as legal advice: we are simply raising a question +for any interested parties to consider, +and make no representation that such measures are necessary or sufficient. +Concerned proxy sites might decide to send a wafer +(named ``NOTICE'' for example) +containing text along the lines of the following. +
    +

    +TO WHOM IT MAY CONCERN + +
    +
    +Do not send me any copyrighted information other than the +document that I am requesting or any of its necessary components. +
    +
    +In particular do not send me any cookies that +are subject to a claim of copyright by anybody. +Take notice that I refuse to be bound by any license condition +(copyright or otherwise) applying to any cookie. +     +

    +Any company that tries to argue in court that the proxy site +was breaching their copyright in the cookies would +be met with the defense that the proxy site gave that company +the opportunity to protect its copyright by simply +not sending cookies after receiving the notice. +

    +Cookies can be as long as four thousand characters, +so there's plenty of space for lawyerly verbosity, +but white space, commas, and semi-colons are +prohibited. +Spaces can be turned into underscores. +Alternatively, +a +URL +could be sent as the cookie value, +pointing to a document containing a notice, +perhaps with a suggestive value such as +
    +http://www.junkbusters.com/ht/en/ijbfaq.html#licenses_on_cookies_refused +
    +But including the notice directly would probably be preferable +because the addressee does not have to look it up. +

    +The +Internet Junkbuster 2.0 +currently sends a full notice as a +``vanilla wafer'' +if cookies are being logged to a cookie jar +and no other wafers have been specified. +It can be suppressed with the +suppress-vanilla-wafer +option, +which might be used in situations where there is an established understanding +between the proxy and all who serve it. +

+

+Junkbusters provides a +CGI +script that lets you +see +your wafers as they appear to servers. +

+Wafers confuse a few fragile servers. +If this troubles you, don't use this option. +

+Any wafers specified are sent to +all sites regardless of the cookiefile. +They are appended after any genuine cookies, +to maintain compliance with +RFC 2109 +in the event that a path was specified for a cookie. +The +RFC's provisions regarding the +$ +character +(such as the +Version +attribute) +are transparent +to the proxy; it simply quotes what was recited by the browser. +

+If you want to send wafers only to specific sites, +you could try putting them your browser's cookie file in a format +conforming to the Netscape +specification, +and then specify in the proxy's cookiefile that cookies are to be +sent to +but not accepted from those sites, so they can't overwrite the file. +This may work with Netscape but not all other browsers. +

+ +

<Feedback>  +Why would anyone want to save their cookies in a ``cookie jar?'' +

+

+We provided this capability just in case anyone wants it. +There are a few possible reasons. +

    +
  • +It's conceivable that +marketing companies might one day +buy +history files and cookie jars from consumers +in the same way that they currently pay them to fill out survey forms. +With this information they could +gather psychographic information, +see which competitors' sites the consumer has visited, +and discover what advertising is being targeted at them. +
  • +Some consumers might +employ semi-automated means of sorting through +their cookie jars, selecting which ones to place in their cookies +file for use by their browsers. +Their decisions could be based on payments offered, +privacy rating systems such as +TRUSTe +proposes, +or their own opinion of the company. +It could be done manually or with software. +
  • +Users may even start ``sharing'' cookies among themselves, +sending back cookies that servers generated for other visitors. +Servers that aren't expecting this possibility +will be misled about their visitors' identities. +Cookies could be shared among users on a single machine, +or across continents via +FTP +and anonymous remailers. +Privacy activists may promote +cookie disinformation campaigns +as a way to defend the public against abuse. +If a significant percentage of people send disinformative cookies, +user tracking via cookies may become less reliable and less used. +

+Anonymity + +

+
+
For details +on how your identity can be revealed while you surf, +see our page on +privacy. +Once you start using +the +Internet Junkbuster +you should find that much of the information +previously indicated on that page will no longer be provided. +If the +REMOTE HOST +indicating your IP address is too close for comfort, +see our suggestions +below +on how to +conceal +your IP address. +We also recommend that you +disable JavaScript +and +Java. + +

<Feedback>  +If I use the Internet Junkbuster, will my anonymity be guaranteed? +

+

+No. Your chances of remaining anonymous are improved, +but unless you are an expert on Internet security +it would be safest to assume that everything you do on the Web +can be attributed to you personally. +

+The +Internet Junkbuster +removes various information about you, +but it's still possible that web sites can find out who you are. +Here's one way this can happen. +

+A few browsers +disclose the user's email address +in certain situations, such as when transferring a file by +FTP. +The +Internet Junkbuster 2.0 +does not filter the +FTP +stream. +If you need this feature, or are concerned about the mail handler +of your browser disclosing your email address, +you might consider +products such as +NSClean. +

+Browsers downloaded as binaries +could use non-standard headers to give out any information +they can have access to: see the manufacturer's license agreement. +It's impossible to anticipate and prevent every breach of privacy that +might occur. +The professionally paranoid prefer browsers available as source code, +because anticipating their behavior is easier. +

+ +

<Feedback>  +Why should I trust my ISP or Junkbusters with my browsing data? +

+

+You shouldn't have to trust us, and you certainly don't have to. +We do not run the proxy as a service, +where we could observe your online behavior. +We provide source code so that everyone can see that the proxy isn't +doing anything sneaky. +

+You are already trusting your +ISP +not to look at an awful lot of information on what you do. +They probably post a +privacy policy +on their site to reassure you. +If they run a proxy for you, using it could actually +make it slightly easier for them to monitor you, +but we doubt that any sane +ISP +would try this, +because if it were discovered customers would desert them. +

+ +

<Feedback>  +What private information from server-bound headers is removed? +

+

+The +Internet Junkbuster +pounces on the following +HTTP +headers in requests to servers, +unless instructed otherwise in the options. +

    +
  • +The +FROM +header, +which a few browsers use to tell your email address to servers, +is dropped +unless the +from +option is set. +
  • +The +USER_AGENT +header +is changed to indicate that the browser is +currently Mozilla (Netscape) 3.01 Gold +with an unremarkable Macintosh configuration. +Misidentification helps resist certain +attacks. +If your browser and hardware happen to be accurately identified, +you might want to change the default. +(Earlier versions of the +Internet Junkbuster +indicated different details; +by altering them periodically we aim to hinder anyone trying to +infer +whether our proxy is present.) +If you don't like the idea +of incorrectly identifying your computer as a Mac, +set it accordingly. + +
  • +The +REFERER +header +(which indicates where the +URL +currently being requested was found) +is dropped. +A single static referer to replace all +real referers may be specified using the +referer +option. +Where no referer is provided by the browser, none is added; +the +add-header +option with arguments such as +-x 'Referer: http://me.me.me' +can be used to send a bogus referer with every request. +
+In +Version 1.4 +and later you can use the +-r @ +option to selectively disclose +REFERER +and +USER_AGENT +to only those sites you nominate. +

+Some browsers +send Referer and User-Agent information under different non-standard headers. +The +Internet Junkbuster 2.0 +stops +UA +headers, +but others may get through. +This information is also available via JavaScript, +so +disable disable +it. +Some search engines +encode the query you typed +in the +URL +that goes to advertisers to target a banner ad at you, +so you will need to block the ad as well as the referer header, +unless you want them (and anyone they might +buy data +from) +to know +everything you ever search for. +

+If you have JavaScript enabled (the default on +most browsers) servers can use it to obtain Referer and User Agent, +as well as your plug-ins. +We recommend +disabling +JavaScript and Java. +

+Currently no +HTTP +response headers (browser bound) +are removed, +not even the +Forwarded: +or +X-Forwarded-For: +headers. +Nor are any added, +unless requested. +We are considering a more flexible header management system for +a future version. +

+ +

<Feedback>  +Might some things break because header information is changed? +

+

+Possibly. If used with a browser less advanced than Netscape 3.0 or IE-3, +indicating an advanced browser +may encourage pages containing extensions that confuse your browser. +If this becomes a problem +upgrade your browser or +use the +user-agent +option to indicate an +older browser. +In +Version 1.4 +and later you can selectively reveal your real browser +to only those sites you nominate. +

+Because different browsers +use different encodings of Russian characters, +certain web servers convert pages on-the-fly according to the User Agent +header. Giving a User Agent with the wrong operating system or +browser manufacturer causes some Russian sites to be garbled; +Russian surfers should +change it +to something closer. +

+Some +page access counters +work by looking at the referer; +they may fail or break when deprived. +

+Some sites depend on getting a referer header, +such as +uclick.com, +which serves comic strips +for many newspaper sites, +including +Doonsbury +for the +Washington Post. +(If you click on that last link, you can then get to a page containing +the strip via the +same +URL +we've linked to under +Doonsbury, +but if you click on the +Doonsbury +link directly, it gives you an error message suggesting that you +use a browser that supports referers.) +In +Version 1.4 +and later you can use the +-r @ +option +and place a line like +>uclick.com +in your cookiefile. +Wired News +used to use referer to decide whether to add a navigation column to +the page, but they have changed that. +

+The weather maps of +Intellicast +have been blocked by their server when no referer or cookie is provided. +You can use the same countermeasure with a line such as +>208.194.150.32 +(or simply get your weather information +elsewhere). +

+Some software vendors, including +Intuit +use +USER_AGENT +to decide which versions of their products to display to you. +With the +default +you get Mac versions. +

+As a last resort if a site you need doesn't seem to be working, +the +proxy configuration +of many browsers allow you to specify + +No Proxy For +any hostname you want. +

+We had reports that on some versions of Netscape the +What's New +feature did not work with the proxy, +but we think we fixed this in Version 2.0.1. +

+ +

<Feedback>  +How is misidentifying my browser good for security and privacy? +

+

+Almost +every +major release of both leading browsers has contained +bugs that allow malicious servers to compromise your privacy and security. +Known bugs are quickly fixed, but millions of copies of the affected +software remain out there, and yours is probably one of them. +The +header +that normally identifies your browser tells such servers exactly which attacks +to use against you. +By misidentifying your browser you reduce the likelihood that they +will be able to mount a successful attack. +

+ +

<Feedback>  +Does the Internet Junkbuster conceal my IP address? +

+

+Web sites get the IP address of any proxy or browser they serve pages to. +If you run the proxy on your own computer the IP address disclosed +is the same as your browser would, unless you use the +forwardfile +option is used to chain to another proxy, +in which case servers only get the last IP address in the chain. +Chaining slightly slows browsing of course, but it improves anonymity. +

+One public proxy that you can +forward to is +lpwa.com +port 8000. +Read about its privacy-enhancing +features and the authentication procedures first, +and note that it blocks +referer +in almost all cases, +as well as some +other headers. +

+ +

<Feedback>  +How can I set the proxy to remember my LPWA password? +

+

+After you log in to +LPWA +it tells your browser to send a +Proxy-authorization +header with each request. +Whenever you shut down the browser and start again with a new browser, +you need to log in again. +If you are the only person using the +Internet Junkbuster +proxy, you can avoid repeated logins to +LPWA +by telling the +Internet Junkbuster +to send the information by placing a line such as +
+   add-header Proxy-authorization: Basic ZHVtbXk=. +
+in the configuration file. +The exact example above +does not work +because the code +ZHVtbXk=. +is a bogus one that +LPWA +would never generate; +follow the procedure below to generate a valid one. +

    +
  1. +Restart your +Internet Junkbuster +with +debug 8 +so you can see the +headers. +
  2. +Log in to +LPWA +and go to any other site. +
  3. +Find the +Proxy-authorization +header from the debug output and paste it +after the word +add-header +into the config file. +Also change the debug value back again. +
  4. +Shut down your browser, start it up again, and +restart the proxy. Test that it works. +
+This trick is convenient for sole users, but is not suitable when +more than one person uses the proxy, because they will all get the +same +LPWA +identity. +

+ +

<Feedback>  +Does the Internet Junkbuster thwart identification by identd? +

+

+We think so, +provided you are not the user running the +proxy. +If your computer (or your +ISP's) +is running the +identd +demon, +servers can ask it for the identity of the +user making the request at time you request a page from them. +But if you're going through a proxy, +they will identify the user name associated with the proxy, not you. +A visit to +http://ident.junkbusters.com +lets you see what's happening. +This test is (quite rightly) blocked by many +firewalls; +just interrupt the transfer if you get an abnormal wait after clicking. +Running other applications +may also expose you via +identd; +the proxy of course doesn't help then. +

+ +

<Feedback>  +Can web sites tell that I'm using the Internet Junkbuster? +

+

+With the default options the proxy doesn't announce itself. +Obvious indications such as +Keep-Alive +headers are +deleted, +but sites might notice that you can cancel cookies faster than +any human could possibly click on a mouse. +(If you want to provide a +plausible explanation for this, +change the User Agent header to a +cookie-free +or +cookie-crunching +browser). +

+But when certain options +are used they could figure out something's going on, +even if they're not pushing cookies. +If you use blocking +they can tell from their logs that the graphics in their pages +are not being requested selectively. +The +add-forwarded-header +option explicitly announces to the server that a proxy is present, +and +sending them +wafers +is of course a dead giveaway. +

+Security + +

+
+
+

<Feedback>  +What happens with Secure Documents (SSL, https:)? +

+

+If you enter a +``Secure Document Area,'' +cookies and other header information +such as User Agent and Referer +are sent encrypted, +so they cannot be filtered. +We recommend getting your browser to alert you when this happens. +(On Netscape: + +Options; + +Security; + +General; + +Show an alert before entering a secure document space.) +We also recommend adding the line +:443 +to the blockfile to stop all but sites specified in an exception +after that line from using SSL. +

+It may be possible to filter encrypted cookies +by combining the blocking proxy with a cryptographic proxy along +the lines of +SafePassage, +but we have not tried this. +

+ +

<Feedback>  +Will using this as my Security Proxy compromise security? +

+

+We're not security experts, but we don't think so. +The whole point of +SSL +is that the +contents of messages are + +encrypted +by the time +they leave the browser and the server. +Eavesdroppers (including proxies) can see where your messages are going +whether you are running a proxy or not, +but they only get to see the contents after they have been encrypted. +

+ +

<Feedback>  +Can I restrict use of the proxy to a set of nominated IP addresses? +

+

+Yes, we added an +access control +file in Version 2.0. +But before you use it please consider why you want to do it. +If the reason is security, +it probably means you need a firewall. +

+The +listen-address +option provides a way of binding the proxy to a single IP address/port. +The right way to do this is to choose a port inside your firewall, and +deny access to it to those outside the firewall. +The +Internet Junkbuster +is not a firewall proxy; +it should not be expected to solve security problems. +

+For background information on firewalls, +see +Yahoo +or a +magazine article +or these well-known books: +Firewalls and Internet Security: Repelling the Wily Hacker +by +William R. Cheswick +and +Steven M. Bellovin +or +Building Internet Firewalls +by +D. Brent Chapman +and +Elizabeth D. Zwicky. +There's + +free Linux software +available, +and a large number of +commercial +products and services. +For an excellent security overview, primer, and compendium reference, see +Practical Unix and Internet Security +by +Simson Garfinkel +and +Gene Spafford. +

+ +

<Feedback>  +Are there any security risks for ISPs or others who offer the proxy? +

+

+Yes. +As with any service offered over the Internet, +hackers can try to misuse it. +A well-run +ISP +will have professionals who are experienced at assessing and containing +these risks. +

+It's possible to set up your machine so +that other people can have access to your proxy, +but if you lack expertise in computer security +you probably shouldn't have your computer configured to offer +this or any other service to the outside world. +

+Hackers can attempt to gain access +to the machine by various attacks, +which we have tried to guard against but don't guarantee to thwart. +They can also use the ``anonymizing'' quality of proxies +to try to cover their tracks while hacking other computers. +For this reason we recommend preventing it being used +as an anonymous +telnet +by putting the pattern +:23 +in the blockfile (it's included as standard equipment). +(Actually the current implementation incidentally blocks telnet due to the +way headers are handled, but it's best not to rely on this.) +If you wish to block all ports except the default +HTTP +port 80, +you can put the lines +
+   : +
+   ~:80 +
+at the beginning of the blockfile, but be aware that some servers +run on non-default ports (e.g. 8080). You might also want to add the line +~:443 +to allow +SSL. +

+On +UNIX ® +systems it is neither necessary nor desirable for the proxy to run as root. +

+Versions 2.0.1 and below may be vulnerable to remote +exploitation of a memory buffer bug; for security reasons all users +are encouraged to +upgrade. +

+If you find any security holes in the code +please +tell us, +along with any suggestions you may have for fixing it. +However, we do not claim that we will be able to do so. +

+We distribute this code in the hope that people +will find it useful, but we provide +no warranty +for it, +and we are not responsible for anyone's use or misuse of it. +

+You may also want to check back periodically for updated versions of the code. +We do not +maintain a mailing list. +To get quick updates, bookmark our +Distribution Information +page. +

<Feedback>  +Description +

+

+junkbuster +is an instrumentable proxy that filters the +HTTP +stream between +web servers and browsers. +Its main purpose is to enhance privacy. +

+Versions before 2.0 used command-line options; +Versions from 2.0 onward use a configuration file. +The following descriptions of the options first give the older +command-line usage, then the new configfile line. +

+In Versions 2.0.1 upwards on Windows, +a start-up message is printed and the configuration is read from the file +junkbstr.ini +if it exists and no argument was given. +

+All files except the configfile +are checked for changes before each page is fetched, +so they may edited without restarting the proxy. +

Options +

+

-b blockfile
blockfile  blockfile
+Block +requests to +URLs +matching any pattern given in the lines of the +blockfile. +The +junkbuster +instead returns status 202, indicating that the request has been accepted +(though not completed), +and a +message identifying itself +(though the browser may +display only a broken image icon). +(Versions before 2.0 returned an error 403 (Forbidden).) +The syntax of a pattern is +[domain][:port][/path] +(the +http:// +or +https:// +protocol part is omitted). +To decide if a pattern matches a target, the domains are compared first, +then the paths. +

+To compare the domains, +the pattern domain and the target +domain specified in the +URL +are each broken into their components. +(Components are separated by the +. +(period) character.) +Next each of the target components +is compared with the corresponding pattern component: last with last, +next-to-last with next-to-last, and so on. +(This is called +right-anchored +matching.) +If all of the pattern components find their match in the target, +then the domains are considered a match. +Case is irrelevant when comparing domain components. +

+A successfully +matching pattern can be an anchored substring of a target, but +not vice versa. +Thus if a pattern doesn't specify a domain, +it matches all domains. +Furthermore, when comparing two components, +the components must either match in their entirety or up to a wildcard +* +(star character) in the pattern. The wildcard feature +implements only a "prefix" match capability ("abc*" vs. "abcdefg"), +not suffix matching ("*efg" vs. "abcdefg") or +infix matching ("abc*efg" vs. "abcdefg"). +The feature is restricted to the domain component; +it is unrelated to the optional +regular expression +feature in the path +(described below). +

+If a numeric port +is specified in the pattern domain, then the target port must +match as well. The default port in a target is port 80. +

+If the domain and port match, +then the target +URL +path is checked for +a match against the path in the pattern. +Paths are compared with a simple case-sensitive +left-anchored substring comparison. +Once again, the pattern can be an +anchored substring of the target, but not vice versa. +A path of +/ +(slash) would match all paths. Wildcards are not considered in +path comparisons. +

+For example, the target +URL +
+   the.yellow-brick-road.com/TinMan/has_no_brain +
+would be matched (and blocked) by the following patterns +
+   yellow-brick-road.com +
+and +
+   Yellow*.COM +
+and +
+   /TinM +
+but not +
+   follow.the.yellow-brick-road.com +
+or +
+   /tinman +
+

+Comments in a blockfile start with a +# +(hash) character and end at a new line. +Blank lines are also ignored. +

+Lines beginning with a +~ +(tilde) character are taken to be +exceptions: +a +URL +blocked by previous patterns that matches the rest of +the line is let through. (The last match wins.) +

+Patterns +may contain +POSIX +regular expressions +provided the +junkbuster +was compiled with this option +(the default in Version 2.0 on). +The idiom +/*.*/ad +can then be used +to match any +URL +containing +/ad +(such as +http://nomatterwhere.com/images/advert/g3487.gif +for example). +These expressions +don't work +in the domain part. +

+In version 1.3 and later +the blockfile and cookiefile are checked for changes before each request. +

-w NAME=VALUE
wafer  NAME=VALUE
+Specifies a pair to be sent as a cookie with every request +to the server. +(Such boring cookies are called +wafers.) +This option may be called more than once to generate multiple wafers. +The original +Netscape specification +prohibited +semi-colons, commas and white space; +these characters will be +URL-encoded +if used in wafers. + + +The Path and Domain attributes are not currently supported. +

+Enforce the cookie management policy specified in the +cookiefile. +If this option is not used all cookies are silently crunched, +so that users who never want cookies aren't bothered by browsers +asking whether each cookie should be accepted. +However, cookies can +still get through +via +JavaScript +and +SSL, +so alerts should be left on. +

+In Version 1.2 and later +this option must be followed by a +filename +containing instructions on which sites are allowed to +receive and set cookies. +By default cookies are dropped in both the browser's request +and the server's response, unless the +URL +requested matches an entry in the +cookiefile. +The matching algorithm is the same as for the blockfile. +A leading +> +character allows +server-bound +cookies only; +a +< +allows only browser-bound cookies; +a +~ +character stops cookies in +both directions. +Thus a cookiefile containing a single line with the two characters +>* +will pass on all cookies to servers but not give any new ones to the browser. +

-j jarfile
jarfile  jarfile
+All Set-cookie attempts by the server are +logged +to +jarfile. +If no wafer is specified, +one containing a +canned notice +(the +vanilla wafer) +is added as an alert to the server +unless the +suppress-vanilla-wafer + +option is invoked. +

-v
suppress-vanilla-wafer
+Suppress the vanilla wafer. +

-t from
from  from
+If the browser +discloses an email address +in the +FROM +header (most don't), +replace it with +from. +If +from +is set to +. +(the period character) +the +FROM +is passed to the server unchanged. +The default is to delete the +FROM +header. +

-r referer
referer  referer
+Whenever the browser discloses the +URL +that +led to +the current request, +replace it with +referer. +If +referer +is set to +. +(period) +the +URL +is passed to the server unchanged. +In +Version 1.4 +and later, if referer is set to +@ +(at) the +URL +is sent in cases where the cookiefile +specifies that a cookie would be sent. +(No way to send bogus referers selectively is provided.) +The default is to delete Referer. +

+Version 2.0 also accepts the spelling +referrer, +which most dictionaries consider correct. +

-u user-agent
user-agent  user-agent
+Information disclosed by the browser +about itself +is replaced with the value +user-agent. +If +user-agent +is set to +. +(period) +the +User-Agent +header is passed to the server unchanged, +along with any +UA +headers produced by +MS-IE +(which would otherwise be deleted). +In +Version 1.4 +and later, if +user-agent +is set to +@ +(at) these headers are sent unchanged in cases where the cookiefile +specifies that a cookie would be sent, +otherwise only default +User-Agent +header is sent. +That default +is Mozilla/3.0 (Netscape) +with an unremarkable +Macintosh +configuration. +If used with a browser less advanced than Mozilla/3.0 or IE-3, the default +may encourage pages containing extensions that confuse the browser. + +

-h [host][:port]
listen-address  [host][:port]
+If +host +is specified, +bind the +junkbuster +to that +IP +address. +If a +port +is specified, use it. +The default +port +is 8000; +the default host is +localhost. +Before Version 2.0.2, +the default was to bind to all +IP +addresses +(INADDR_ANY); +but this has been restricted to +localhost +to avoid unintended security breaches. +(To open the proxy to all, use the line +
+   listen-address :8000 +
+in the configuration file.) +

-f forward_host[:port]
forwardfile  forwardfile
+Version 1.X required all +HTTP +requests from the client to be forwarded to the same destination. +Version 2.0 takes its routing specification from a +forwardfile, +allowing selection of the proxy (a.k.a. forwarding host) and gateway +according to the +URL. +Here is a typical line. +
+
+*         lpwa.com:8000      .      .
+
+

+Each line contains four fields: +target, +forward_to, +via_gateway_type +and +gateway. +As usual, the +last +target +domain that matches the requested +URL +wins, +and the +* +character alone matches any domain. +The target domain need not be a fully qualified +hostname; it can be a general domain such as +com +or +co.uk +or even just a port number. +For example, because +LPWA +does not handle +SSL, +the line above will typically be followed by a line such as +
+

+:443  .      .      .
+
+to allow SSL transactions to proceed directly. +The cautious would also +add an entry in their blockfile to stop transactions +to port 443 for all but specified trusted sites. +

+If the winning +forward_to +field is +. +(the dot character) the proxy connects +directly to the server given in the +URL, +otherwise it forwards to the host and port number specified. +The default port is 8000. +The +via_gateway_type +and +gateway +fields also use a dot to indicate no gateway protocol. +The gateway protocols are explained +below. +

+The example line above in a forwardfile alone +would send everything through port 8000 at +lpwa.com +with no gateway protocol, +and is equivalent to the old +-f lpwa.com:8000 +with no +-g +option. +For more information see the example file provided with the distribution. +

+Configure with care: no loop detection is performed. +When setting up chains of proxies that might loop back, try adding +Squid. +

-g gw_protocol[:[gw_host][:gw_port]]
+Use +gw_protocol +as the gateway protocol. +This option was introduced in Version 1.4, +but was folded into the +forwardfile +option in Version 2.0. +The default is to use no gateway protocol; +this may be explicitly specified as +direct +on the command line +or the dot character in the forwardfile. +The +SOCKS4 +protocol may be specified as +socks +or +socks4. +The +SOCKS4A +protocol is specified as +socks4a. +The +SOCKS5 +protocol is not currently supported. +The default +SOCKS +gw_port +is 1080. +

+The user's browser should +not +be +configured +to use +SOCKS; +the proxy conducts the negotiations, not the browser. +

+The user identification capabilities of +SOCKS4 +are deliberately not used; +the user is always identified to the +SOCKS +server as +userid=anonymous. +If the server's policy is to reject requests from +anonymous, +the proxy will not work. +Use a +debug +value of 3 +to see the status returned by the server. +

-d N
debug  N
+Set debug mode. +The most common value is 1, +to +pinpoint +offensive +URLs, +so they can be added to the blockfile. +The value of +N +is a bitwise +logical-OR +of the following values: +
+1 = URLs (show each URL requested by the browser);
+2 = Connections (show each connection to or from the proxy);
+4 = I/O (log I/O errors);
+8 = Headers (as each header is scanned, show the header and what is done to it);
+16 = Log everything (including debugging traces and the contents of the pages).
+Multiple +debug +lines are permitted; they are logical OR-ed together. +

+Because most browsers send several requests in parallel +the debugging output may appear intermingled, so the +single-threaded +option is recommended when using +debug +with +N +greater than 1. + +

-y
add-forwarded-header
+Add +X-Forwarded-For +headers to the server-bound +HTTP +stream +indicating the client +IP +address +to the server, +in the new style of +Squid 1.1.4. +If you want the traditional +HTTP_FORWARDED +response header, add it manually with the +-x +option. + +

-x HeaderText
add-header  HeaderText
+Add the +HeaderText +verbatim to requests to the server. +Typical uses include +adding old-style forwarding notices such as +Forwarded: by http://pro-privacy-isp.net +and reinstating the +Proxy-Connection: Keep-Alive +header +(which the +junkbuster +deletes so as +not +to reveal its existence). +No checking is done for correctness or plausibility, +so it can be used to throw any old trash into the server-bound +HTTP +stream. +Please don't litter. + +

-s
single-threaded
+Doesn't +fork() +a separate process +(or create a separate thread) +to handle each connection. +Useful when debugging to keep the process single threaded. +

-l logfile
logfile  logfile
+Write all debugging data into +logfile. +The default +logfile +is the standard output. +


aclfile  aclfile
+Unless this option is used, the proxy talks to anyone who can connect to it, +and everyone who can has equal permissions on where they can go. +An access file allows restrictions to be placed on these two policies, +by distinguishing some +source +IP +addresses and/or +some +destination +addresses. +(If a +forwarder or a gateway +is being used, its address is considered the destination address, +not the ultimate +IP +address of the +URL +requested.) +

+Each line of the access file begins with +either the word +permit +or +deny +followed by source and (optionally) destination addresses +to be matched against those of the +HTTP +request. +The last matching line specifies the result: if it was a +deny +line or if no line matched, +the request will be refused. +

+A source or destination +can be specified as a single numeric +IP +address, +or with a hostname, provided that the host's name +can be resolved to a numeric address: this cannot be used to block all +.mil +domains for example, +because there is no single address associated with that domain name. +Either form may be followed by a slash and an integer +N, +specifying a subnet mask of +N +bits. +For example, +permit 207.153.200.72/24 +matches the entire Class-C subnet from +207.153.200.0 +through 207.153.200.255. +(A netmask of 255.255.255.0 corresponds to 24 bits of +ones in the netmask, as with +*_MASKLEN=24.) +A value of 16 would be used for a Class-B subnet. +A value of zero for +N +in the subnet mask length will cause any address to match; +this can be used to express a default rule. +For more information see the example file provided with the distribution. +

+If you like these access controls +you should probably have +firewall; +they are not intended to replace one. +


trustfile  trustfile
+This feature is experimental, has not been fully documented and is +very subject to change. +The goal is for parents to be able to choose a page or site whose +links they regard suitable for their +young children +and for the proxy to allow access only to sites mentioned there. +To do this the proxy examines the +referer +variable on each page request to check they resulted from +a click on the ``trusted referer'' site: if so the referred site +is added to a list of trusted sites, so that the child can +then move around that site. +There are several uncertainties in this scheme that experience may be +able to iron out; check back in the months ahead. +


trust_info_url  trust_info_url
+When access is denied due to lack of a trusted referer, this +URL +is displayed with a message pointing the user to it for further information. +


hide-console
+In the Windows version only, instructs the program +to disconnect from and hide the command console after starting. +

-a
+(Obsolete) Accept the server's +Set-cookie +headers, passing them through to the browser. +This option was removed in Version 1.2 +and replaced by an improvement to the +-c +option. +

<Feedback>  +Installation and Use +

+

+Browsers must be told where to find the +junkbuster +(e.g. +localhost +port 8000). +To set the +HTTP +proxy in Netscape 3.0, +go through: + +Options; + +Network Preferences; + +Proxies; + +Manual Proxy Configuration; + +View. +See the +FAQ +for other browsers. +The +Security Proxy +should also be set to the same values, +otherwise +shttp: +URLs +won't work. +

+Note the limitations +explained in the +FAQ. +

+ +

<Feedback>  +Checking Options +

+

+To allow users to +check +that a +junkbuster +is running and how it is configured, +it intercepts requests for any +URL +ending in +/show-proxy-args +and blocks it, +returning instead returns information on its +version number and +current configuration +including the contents of its blockfile. +To get an explicit warning that no +junkbuster +intervened if the proxy was not configured, +it's best to point it to a +URL +that does this, such as +http://internet.junkbuster.com/cgi-bin/show-proxy-args +on Junkbusters's website. +
