83 2.2.4. Why can I change the configuration with a browser? Does that not
84 raise security issues?
86 What I don't understand, is how I can browser edit the config file as
87 a regular user, while the whole /etc/junkbuster hierarchy belongs to
88 the user "junkbuster", with only 644 perms.
90 When you use the browser-based editor, JunkBuster itself is writing to
91 the config files. Because JunkBuster is running as the user
92 "junkbuster", it can update the config files.
94 If you don't like this, setting "enable-edit-actions 0" in the config
95 file will disable the browser-based editor. If you're that paranoid,
96 you should also consider setting "enable-remote-toggle 0" to prevent
97 browser-based enabling/disabling of JunkBuster.
99 Note that normally only local users can connect to JunkBuster, so this
100 is not (normally) a security problem.

105 2.3.1. I noticed considerable delays in page requests compared to the old
108 Using the default filtering configuration, I noticed considerable
109 delays in page requests compared to the old IJB. Loading pages with
110 large contents seemed to take forever, then suddenly delivering all
113 The whole content must be loaded in order to filter, and nothing is is
114 sent to the browser during this time. The loading time does not really
115 change in real numbers, but the feeling is different, because most
116 browsers are able to start rendering incomplete content, giving the
117 user a feeling of "it works".
119 To modify the content of a page (i.e. make frames resizeable again,
120 etc.) and not just replace ads, the Internet Junkbuster needs to
121 download the entire page first, do its content magic and then send the

125 2.3.2. What is the "http://i.j.b/"?
127 Since JunkBuster sits between your web browser and the Internet, it
128 can be programmed to handle certain pages specially.
130 With recent versions of JunkBuster (version 2.9.x), you can get some
131 information about JunkBuster and change some settings by going to
132 http://i.j.b/ or, equivalently, http://ijbswa.sourceforge.net/config/
133 (Note that i.j.b is far easier to type but may not work in some
136 These pages are *not* forwarded to a server on the internet - instead
137 they are handled by a special web server which is built in to
140 If you are not running JunkBuster, then http://i.j.b/ will fail, and
141 http://ijbswa.sourceforge.net/config/ will return a web page telling
142 you you're not running JunkBuster.
144 If you have version 2.0.2, then the equivalent is
145 http://example.com/show-proxy-args (but you get far less information,
146 and you should really consider upgrading to 2.9.x).

149 2.3.3. I get the message 'Bad File Descriptor', why?
152 _________________________________________________________________
154 2.3.4. How do I chain Junkbuster with other proxies (e.g. squid)?
157 _________________________________________________________________
159 2.3.5. I would like to help you, what do I do?
161 Well, helping the team is always a good idea. We welcome new
162 developers, RPM gurus or documentation makers. Simply get an account
163 on sourceforge.net and mail your id to the developer mailing list.
164 Once we have added you to the team, you'll have write access to the
165 CVS repository, and we'll find a suitable task for you together.
166 _________________________________________________________________
168 2.3.6. Do you still maintain the blocklists?
170 No. The format of the blocklists has changed significantly in the
171 versions 2.9.x. Once we have released the new version, there will
172 again be blocklists that you can update automatically.
173 _________________________________________________________________
175 2.3.7. How can I submit new ads?
177 As of now, please discontinue to submit new ad blocking infos. Once we
178 have released the new version, there will again be a form on the
179 website, which you can use to contribute new ads.
180 _________________________________________________________________
182 2.3.8. How can I hide my IP address?
184 You cannot hide your IP address with Junkbuster.
185 _________________________________________________________________
187 2.3.9. What is the imagefile (simage.ini, etc.) for?
189 Anytime the Junkbuster determines (with the help of the blocklist)
190 that a URL contains an advertisement, it has to decide whether this
191 advertisement is an image or not. The Junkbuster uses the imagefile
