9 privoxy [--help ] [--version ] [--no-daemon ] [--pidfile pidfile ]
10 [--user user[.group] ] [--chroot ] [--pre-chroot-nslookup hostname ]
11 [configfile ]
12
15 Privoxy may be invoked with the following command line options:
16 --help Print brief usage info and exit.
18 --version
20 Print version info and exit.
21 --no-daemon
23 Don't become a daemon, i.e. don't fork and become process
24 group leader, don't detach from controlling tty, and do all log‐
25 ging there.
26 --pidfile pidfile
28 On startup, write the process ID to pidfile. Delete the pidfile
29 on exit. Failure to create or delete the pidfile is non-fatal.
30 If no --pidfile option is given, no PID file will be used.
31 --user user[.group]
33 After (optionally) writing the PID file, assume the user ID of
34 user and the GID of group, or, if the optional group was not
35 given, the default group of user. Exit if the privileges are not
36 sufficient to do so.
37 --chroot
39 Before changing to the user ID given in the --user option,
40 chroot to that user's home directory, i.e. make the kernel pre‐
41 tend to the Privoxy process that the directory tree starts
42 there. If set up carefully, this can limit the impact of possi‐
43 ble vulnerabilities in Privoxy to the files contained in that
44 hierarchy.
45 --pre-chroot-nslookup hostname
47 Initialize the resolver library using hostname before
48 chroot'ing. On some systems this reduces the number of files
49 that must be copied into the chroot tree.
50 If the configfile is not specified on the command line, Privoxy
52 will look for a file named config in the current directory. If no con‐
53 figfile is found, Privoxy will fail to start.
54
56 Privoxy is a non-caching web proxy with advanced filtering capabilities
57 for enhancing privacy, modifying web page data and HTTP headers, con‐
58 trolling access, and removing ads and other obnoxious Internet junk.
59 Privoxy has a flexible configuration and can be customized to suit
60 individual needs and tastes. It has application for both stand-alone
61 systems and multi-user networks.
62 Privoxy is Free Software and licensed under the GPL2.
64 Privoxy is an associated project of Software in the Public Interest
66 (SPI). Donations are welcome.
67
69 Browsers can either be individually configured to use Privoxy as a HTTP
70 proxy (recommended), or Privoxy can be combined with a packet filter to
71 build an intercepting proxy (see config). The default setting is for
72 localhost, on port 8118 (configurable in the main config file). To
73 set the HTTP proxy in Firefox, go through: Tools; Options; General;
74 Connection Settings; Manual Proxy Configuration.
75 For Internet Explorer, go through: Tools; Internet Properties; Connec‐
77 tions; LAN Settings.
78 The Secure (SSL) Proxy should also be set to the same values, otherwise
80 https: URLs will not be proxied. Note: Privoxy can only proxy HTTP and
81 HTTPS traffic. Do not try it with FTP or other protocols. HTTPS
82 presents some limitations, and not all features will work with HTTPS
83 connections.
84 For other browsers, check the documentation.
86
88 Privoxy can be configured with the various configuration files. The
89 default configuration files are: config, default.filter, default.action
90 and default.action. user.action should be used for locally defined
91 exceptions to the default rules in match-all.action and default.action,
92 and user.filter for locally defined filters. These are well commented.
93 On Unix and Unix-like systems, these are located in /etc/privoxy/ by
94 default.
95 Privoxy uses the concept of actions in order to manipulate the data
97 stream between the browser and remote sites. There are various actions
98 available with specific functions for such things as blocking web
99 sites, managing cookies, etc. These actions can be invoked individually
100 or combined, and used against individual URLs, or groups of URLs that
101 can be defined using wildcards and regular expressions. The result is
102 that the user has greatly enhanced control and freedom.
103 The actions list (ad blocks, etc) can also be configured with your web
105 browser at http://config.privoxy.org/ (assuming the configuration
106 allows it). Privoxy's configuration parameters can also be viewed at
107 the same page. In addition, Privoxy can be toggled on/off. This is an
108 internal page, and does not require Internet access.
109 See the User Manual for a detailed explanation of installation, general
111 usage, all configuration options, new features and notes on upgrading.

124 Various other files should be included, but may vary depending on plat‐
126 form and build configuration. Additional documentation should be
127 included in the local documentation directory.
128
130 Privoxy terminates on the SIGINT, SIGTERM and SIGABRT signals. Log
131 rotation scripts may cause a re-opening of the logfile by sending a
132 SIGHUP to Privoxy. Note that unlike other daemons, Privoxy does not
133 need to be made aware of config file changes by SIGHUP -- it will
134 detect them automatically.
