+ <h2>NAME</h2>privoxy - Privacy Enhancing Proxy <a name="lbAC" id=
+ "lbAC"> </a>
+
+ <h2>SYNOPSIS</h2>
+
+ <p><b>privoxy</b> [<b>--chroot</b> ] [<b>--config-test</b> ] [<b>--help</b>
+ ] [<b>--no-daemon</b> ] [<b>--pidfile</b> <i>pidfile</i> ]
+ [<b>--pre-chroot-nslookup</b> <i>hostname</i> ] [<b>--user</b>
+ <i>user[.group]</i> ] [<b>--version</b> ] [<i>configfile</i> ]</p>
+
+ <p><a name="lbAD" id="lbAD"> </a></p>
+
+ <h2>OPTIONS</h2>
+
+ <p><b>Privoxy</b> may be invoked with the following command line
+ options:</p>
+
+ <dl compact>
+ <dt><b>--chroot</b></dt>
+
+ <dd>Before changing to the user ID given in the --user option, chroot to
+ that user's home directory, i.e. make the kernel pretend to the
+ <b>Privoxy</b> process that the directory tree starts there. If set up
+ carefully, this can limit the impact of possible vulnerabilities in
+ <b>Privoxy</b> to the files contained in that hierarchy.</dd>
+
+ <dt><b>--config-test</b></dt>
+
+ <dd>
+ Exit after loading the configuration files before binding to the listen
+ address. The exit code signals whether or not the configuration files
+ have been successfully loaded.
+
+ <p>If the exit code is 1, at least one of the configuration files is
+ invalid, if it is 0, all the configuration files have been successfully
+ loaded (but may still contain errors that can currently only be
+ detected at run time).</p>
+
+ <p>This option doesn't affect the log setting, combination with
+ "--no-daemon" is recommended if a configured log file shouldn't be
+ used.</p>
+ </dd>
+
+ <dt><b>--help</b></dt>
+
+ <dd>Print brief usage info and exit.</dd>
+
+ <dt><b>--no-daemon</b></dt>
+
+ <dd>Don't become a daemon, i.e. don't fork and become process group
+ leader, don't detach from controlling tty, and do all logging there.</dd>
+
+ <dt><b>--pidfile</b> <i>pidfile</i></dt>
+
+ <dd>On startup, write the process ID to <i>pidfile</i>. Delete the
+ <i>pidfile</i> on exit. Failure to create or delete the <i>pidfile</i> is
+ non-fatal. If no <b>--pidfile</b> option is given, no PID file will be
+ used.</dd>
+
+ <dt><b>--pre-chroot-nslookup</b> <i>hostname</i></dt>
+
+ <dd>Initialize the resolver library using <i>hostname</i> before
+ chroot'ing. On some systems this reduces the number of files that must be
+ copied into the chroot tree.</dd>
+
+ <dt><b>--user</b> <i>user[.group]</i></dt>
+
+ <dd>After (optionally) writing the PID file, assume the user ID of
+ <i>user</i> and the GID of <i>group</i>, or, if the optional <i>group</i>
+ was not given, the default group of <i>user</i>. Exit if the privileges
+ are not sufficient to do so.</dd>
+
+ <dt><b>--version</b></dt>
+
+ <dd>Print version info and exit.</dd>
+ </dl>
+
+ <p>If the <i>configfile</i> is not specified on the command line,
+ <b>Privoxy</b> will look for a file named <i>config</i> in the current
+ directory. If no <i>configfile</i> is found, <b>Privoxy</b> will fail to
+ start. <a name="lbAE" id="lbAE"> </a></p>
+
+ <h2>DESCRIPTION</h2>
+
+ <p>Privoxy is a non-caching web proxy with advanced filtering capabilities
+ for enhancing privacy, modifying web page data and HTTP headers,
+ controlling access, and removing ads and other obnoxious Internet junk.
+ Privoxy has a flexible configuration and can be customized to suit
+ individual needs and tastes. It has application for both stand-alone
+ systems and multi-user networks.</p>
+
+ <p>Privoxy is Free Software and licensed under the GNU GPLv2.</p>
+
+ <p>Privoxy is an associated project of Software in the Public Interest
+ (SPI).</p>
+
+ <p>Helping hands and donations are welcome:</p>

+
+ <h2>INSTALLATION AND USAGE</h2>
+
+ <p>Browsers can either be individually configured to use <b>Privoxy</b> as
+ a HTTP proxy (recommended), or <b>Privoxy</b> can be combined with a packet
+ filter to build an intercepting proxy (see <i>config</i>). The default
+ setting is for localhost, on port 8118 (configurable in the main config
+ file). To set the HTTP proxy in Firefox, go through: <b>Tools</b>;
+ <b>Options</b>; <b>General</b>; <b>Connection Settings</b>; <b>Manual Proxy
+ Configuration</b>.</p>
+
+ <p>For Internet Explorer, go through: <b>Tools</b>; <b>Internet
+ Properties</b>; <b>Connections</b>; <b>LAN Settings</b>.</p>
+
+ <p>The Secure (SSL) Proxy should also be set to the same values, otherwise
+ https: URLs will not be proxied. Note: <b>Privoxy</b> can only proxy HTTP
+ and HTTPS traffic. Do not try it with FTP or other protocols. HTTPS
+ presents some limitations, and not all features will work with HTTPS
+ connections.</p>
+
+ <p>For other browsers, check the documentation. <a name="lbAG" id=
+ "lbAG"> </a></p>
+
+ <h2>CONFIGURATION</h2>
+
+ <p><b>Privoxy</b> can be configured with the various configuration files.
+ The default configuration files are: <i>config</i>, <i>default.filter</i>,
+ <i>default.action</i> and <i>default.action</i>. <i>user.action</i> should
+ be used for locally defined exceptions to the default rules in
+ <i>match-all.action</i> and <i>default.action</i>, and <i>user.filter</i>
+ for locally defined filters. These are well commented. On Unix and
+ Unix-like systems, these are located in <i>/etc/privoxy/</i> by
+ default.</p>
+
+ <p><b>Privoxy</b> uses the concept of <b>actions</b> in order to manipulate
+ the data stream between the browser and remote sites. There are various
+ actions available with specific functions for such things as blocking web
+ sites, managing cookies, etc. These actions can be invoked individually or
+ combined, and used against individual URLs, or groups of URLs that can be
+ defined using wildcards and regular expressions. The result is that the
+ user has greatly enhanced control and freedom.</p>
+
+ <p>The actions list (ad blocks, etc) can also be configured with your web
+ browser at <a href=
+ "http://config.privoxy.org/">http://config.privoxy.org/</a> (assuming the
+ configuration allows it). <b>Privoxy's</b> configuration parameters can
+ also be viewed at the same page. In addition, <b>Privoxy</b> can be toggled
+ on/off. This is an internal page, and does not require Internet access.</p>
+
+ <p>See the <i>User Manual</i> for a detailed explanation of installation,
+ general usage, all configuration options, new features and notes on
+ upgrading. <a name="lbAH" id="lbAH"> </a></p>

+
+ <h2>SIGNALS</h2>
+
+ <p><b>Privoxy</b> terminates on the <b>SIGINT</b> and <b>SIGTERM</b>
+ signals. Log rotation scripts may cause a re-opening of the logfile by
+ sending a <b>SIGHUP</b> to <b>Privoxy</b>. Note that unlike other daemons,
+ <b>Privoxy</b> does not need to be made aware of config file changes by
+ <b>SIGHUP</b> -- it will detect them automatically. Signals other than the
+ ones listed above aren't explicitly handled and result in the default
+ action defined by the operating system. <a name="lbAJ" id=

+ feature requests, reporting problems, and other questions. <a name="lbAK"
