15 \fBPrivoxy\fR may be invoked with the following command line
19 Before changing to the user ID given in the \-\-user option, chroot to
20 that user's home directory, i.e. make the kernel pretend to the
21 \fBPrivoxy\fR process that the directory tree starts
22 there. If set up carefully, this can limit the impact of possible
23 vulnerabilities in \fBPrivoxy\fR to the files contained in
27 Exit after loading the configuration files before binding to
28 the listen address. The exit code signals whether or not the
29 configuration files have been successfully loaded.
31 If the exit code is 1, at least one of the configuration files
32 is invalid, if it is 0, all the configuration files have been
33 successfully loaded (but may still contain errors that can
34 currently only be detected at run time).
36 This option doesn't affect the log setting, combination with
37 "--no-daemon" is recommended if a configured log file shouldn't
41 Print brief usage info and exit.
44 Don't become a daemon, i.e. don't fork and become process group
45 leader, don't detach from controlling tty, and do all logging there.
47 \fB\-\-pidfile \fIpidfile\fB\fR
48 On startup, write the process ID to \fIpidfile\fR.
49 Delete the \fIpidfile\fR on exit.
50 Failure to create or delete the \fIpidfile\fR
51 is non-fatal. If no \fB\-\-pidfile\fR option is given, no PID file will be used.
53 \fB\-\-pre-chroot-nslookup \fIhostname\fB\fR
54 Initialize the resolver library using \fIhostname\fR
55 before chroot'ing. On some systems this reduces the number of files
56 that must be copied into the chroot tree.
58 \fB\-\-user \fIuser[.group]\fB\fR
59 After (optionally) writing the PID file, assume the user ID of
60 \fIuser\fR and the GID of
61 \fIgroup\fR, or, if the optional
62 \fIgroup\fR was not given, the default group of
63 \fIuser\fR. Exit if the privileges are not
67 Print version info and exit.
69 If the \fIconfigfile\fR is not specified on the command line,
70 \fBPrivoxy\fR will look for a file named
71 \fIconfig\fR in the current directory. If no
72 \fIconfigfile\fR is found, \fBPrivoxy\fR will
76 Privoxy is a non-caching web proxy with advanced filtering capabilities
77 for enhancing privacy, modifying web page data and HTTP headers, controlling
78 access, and removing ads and other obnoxious Internet junk. Privoxy has a
79 flexible configuration and can be customized to suit individual needs and tastes.
80 It has application for both stand-alone systems and multi-user networks.
82 Privoxy is Free Software and licensed under the GNU GPLv2.
84 Privoxy is an associated project of Software in the Public Interest (SPI).

93 .SH "INSTALLATION AND USAGE"
95 Browsers can either be individually configured to use
96 \fBPrivoxy\fR as a HTTP proxy (recommended),
97 or \fBPrivoxy\fR can be combined with a packet
98 filter to build an intercepting proxy
99 (see \fIconfig\fR). The default setting is for
100 localhost, on port 8118 (configurable in the main config file). To set the
101 HTTP proxy in Firefox, go through: \fBTools\fR;
102 \fBOptions\fR; \fBGeneral\fR;
103 \fBConnection Settings\fR;
104 \fBManual Proxy Configuration\fR.
106 For Internet Explorer, go through: \fBTools\fR;
107 \fBInternet Properties\fR; \fBConnections\fR;
110 The Secure (SSL) Proxy should also be set to the same values, otherwise
111 https: URLs will not be proxied. Note: \fBPrivoxy\fR can only
112 proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
113 HTTPS presents some limitations, and not all features will work with HTTPS
116 For other browsers, check the documentation.
119 \fBPrivoxy\fR can be configured with the various configuration
120 files. The default configuration files are: \fIconfig\fR,
121 \fIdefault.filter\fR, \fIdefault.action\fR and
122 \fIdefault.action\fR. \fIuser.action\fR should
123 be used for locally defined exceptions to the default rules in
124 \fImatch-all.action\fR and \fIdefault.action\fR,
125 and \fIuser.filter\fR for locally defined filters. These are
126 well commented. On Unix and Unix-like systems, these are located in
127 \fI/etc/privoxy/\fR by default.
129 \fBPrivoxy\fR uses the concept of \fBactions\fR
130 in order to manipulate the data stream between the browser and remote sites.
131 There are various actions available with specific functions for such things
132 as blocking web sites, managing cookies, etc. These actions can be invoked
133 individually or combined, and used against individual URLs, or groups of URLs
134 that can be defined using wildcards and regular expressions. The result is
135 that the user has greatly enhanced control and freedom.
137 The actions list (ad blocks, etc) can also be configured with your
138 web browser at http://config.privoxy.org/
139 (assuming the configuration allows it).
140 \fBPrivoxy's\fR configuration parameters can also be viewed at
141 the same page. In addition, \fBPrivoxy\fR can be toggled on/off.
142 This is an internal page, and does not require Internet access.
144 See the \fIUser Manual\fR for a detailed
145 explanation of installation, general usage, all configuration options, new
146 features and notes on upgrading.

162 Various other files should be included, but may vary depending on platform
163 and build configuration. Additional documentation should be included in the local
164 documentation directory.
167 \fBPrivoxy\fR terminates on the \fBSIGINT\fR
168 and \fBSIGTERM\fR signals. Log
169 rotation scripts may cause a re-opening of the logfile by sending a
170 \fBSIGHUP\fR to \fBPrivoxy\fR. Note that unlike
171 other daemons, \fBPrivoxy\fR does not need to be made aware of
172 config file changes by \fBSIGHUP\fR -- it will detect them
173 automatically. Signals other than the ones listed above aren't explicitly
174 handled and result in the default action defined by the operating system.

178 developers, for feature requests, reporting problems, and other questions.
