privoxy - Privacy Enhancing Proxy

<H2>SYNOPSIS</H2>
<P>
<B>privoxy</B> [<B>--help</B> ] [<B>--version</B> ] [<B>--no-daemon</B> ] [<B>--pidfile </B><I>pidfile</I><B></B> ] [<B>--user </B><I>user[.group]</I><B></B> ] [<B></B><I>configfile</I><B></B> ]<B> (UNIX)</B>
<P>
<P>
<B>privoxy.exe</B> [<B></B><I>configfile</I><B></B> ]<B> (Windows)</B>
<P>
<A NAME="lbAD"> </A>
<H2>OPTIONS</H2>
<P>
<B>Privoxy</B> may be invoked with the following command line
options:
<DL COMPACT>
<DT><B>--help</B><DD>
Print brief usage info and exit.
<DT><B>--version</B><DD>
Print version info and exit.
<DT><B>--no-daemon</B><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.
<DT><B>--pidfile </B><I>pidfile</I><B></B><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.
<DT><B>--user </B><I>user[.group]</I><B></B><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.
</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 (except on Win32 where
it will try <I>config.txt</I>). If no
<I>configfile</I> is found, <B>Privoxy</B> will
fail to start.
<A NAME="lbAE"> </A>
<H2>DESCRIPTION</H2>
<P>
<B>Privoxy</B> is a web proxy with advanced filtering
capabilities for protecting privacy, filtering web page content, managing
cookies, controlling access, and removing ads, banners, pop-ups and other
obnoxious Internet junk. <B>Privoxy</B> has a very
flexible configuration and can be customized to suit individual needs and
tastes. <B>Privoxy</B> has application for both
stand-alone systems and multi-user networks.
<P>
<B>Privoxy</B> is based on <B>Internet
Junkbuster</B> (tm).
<A NAME="lbAF"> </A>
<H2>INSTALLATION AND USAGE</H2>
<P>
Browsers must be individually configured to use <B>Privoxy</B> as
a HTTP proxy. The default setting is for localhost, on port 8118
(configurable in the main config file). To set the HTTP proxy in Netscape
and Mozilla, go through: <B>Edit</B>;
<B>Preferences</B>; <B>Advanced</B>;
<B>Proxies</B>; <B>Manual Proxy Configuration</B>;
<B>View</B>.
<P>
For Internet Explorer, go through: <B>Tools</B>;
<B>Internet Properties</B>; <B>Connections</B>;
<B>LAN Settings</B>.
<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.
<P>
For other browsers, check the documentation.
<A NAME="lbAG"> </A>
<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>, and
<I>default.action</I>. <I>user.action</I> should
be used for locally defined exceptions to the default rules of
<I>default.action</I> These are all well commented. On Unix
and Unix-like systems, these are located in
<I>/etc/privoxy/</I> by default. On Windows, OS/2 and AmigaOS,
these files are in the same directory as the <B>Privoxy</B>
executable.
<P>
The name and number of configuration files has changed from previous
versions. In fact, the configuration itself is changed and much more
sophisticated. See the user-manual for a complete
explanation of all configuration options and general usage, and notes for
upgrading from <B>Junkbuster</B> and earlier <B>Privoxy</B>
versions.
<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>
<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.
<A NAME="lbAH"> </A>
<H2>SAMPLE CONFIGURATION</H2>
<P>
A brief example of what a simple <I>default.action</I>
configuration might look like:
<P>
<PRE>
# Define a few useful custom aliases for later use
{{alias}}
# Useful aliases
+crunch-cookies = +crunch-incoming-cookies +crunch-outgoing-cookies
-crunch-cookies = -crunch-incoming-cookies -crunch-outgoing-cookies
+imageblock = +block +handle-as-image
# Fragile sites should have the minimum changes
fragile = -block -deanimate-gifs -fast-redirects -filter \
-hide-referer -prevent-cookies -kill-popups
## Turn some actions on ################################
{ \
-add-header \
-block \
+deanimate-gifs{last} \
-downgrade-http-version \
-fast-redirects \
+filter{html-annoyances} \
+filter{js-annoyances} \
+filter{content-cookies} \
+filter{webbugs} \
+filter{banners-by-size} \
+hide-forwarded-for-headers \
+hide-from-header{block} \
+hide-referrer{forge} \
-hide-user-agent \
-handle-as-image \
+set-image-blocker{pattern} \
-limit-connect \
+prevent-compression \
+session-cookies-only \
-crunch-cookies \
-kill-popups \
}
/ # '/' Matches *all* URL patterns
# Block, and treat these URL patterns as if they were 'images'.
# We would expect these to be ads.
{+imageblock}
.ad.doubleclick.net
.a[0-9].yimg.com/(?:(?!/i/).)*$
ad.*.doubleclick.net
# Block any URLs that match these patterns
{+block}
ad*.
.*ads.

/.*count(er)?\.(pl|cgi|exe|dll|asp|php[34]?)
.hitbox.com
# Make exceptions for these harmless ones that would be
# caught by our +block patterns just above.
{-block}
adsl.
advice.
.*downloads.
</PRE>
<P>
Then for a <I>user.action</I>, we would put local,
narrowly defined exceptions:
<P>
<PRE>
# Re-define aliases as needed here
{{alias}}
# Useful aliases
-crunch-cookies = -crunch-incoming-cookies -crunch-outgoing-cookies
# Set personal exceptions to the policies in default.action #######
# Sites where we want persistant cookies, so allow *all* cookies
{-crunch-cookies -session-cookies-only}
.redhat.com
.sun.com
.msdn.microsoft.com
# This site breaks easily.
{-block -fast-redirects}
.forbes.com
</PRE>
<P>
See the comments in the configuration files themselves, or the
<I>user-manual</I>
for explanations of the above syntax, and other <B>Privoxy</B>
configuration options.
<A NAME="lbAI"> </A>
<H2>FILES</H2>
<P>
<PRE>
<I>/usr/sbin/privoxy</I>
<I>/etc/privoxy/config</I>
<I>/etc/privoxy/default.action</I>
<I>/etc/privoxy/standard.action</I>
<I>/etc/privoxy/user.action</I>
<I>/etc/privoxy/default.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. More documentation should be included in the local
documentation directory.
<A NAME="lbAJ"> </A>
<H2>SIGNALS</H2>
<P>
<B>Privoxy</B> terminates on the <B>SIGINT</B>,
<B>SIGTERM</B> and <B>SIGABRT</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.
