<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>FILES</h2>
<pre>
<i>/usr/sbin/privoxy</i>
<i>/etc/privoxy/config</i>
<i>/etc/privoxy/match-all.action</i>
<i>/etc/privoxy/default.action</i>
<i>/etc/privoxy/user.action</i>
<i>/etc/privoxy/default.filter</i>
<i>/etc/privoxy/user.filter</i>
<i>/etc/privoxy/trust</i>
<i>/etc/privoxy/templates/*</i>
<i>/var/log/privoxy/logfile</i>
</pre>
<p>Various other files should be included, but may vary depending on
platform and build configuration. Additional documentation should be
included in the local documentation directory. <a name="lbAI" id=
"lbAI"> </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=
"lbAJ"> </a></p>

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