privoxy - Privacy Enhancing Proxy
] [ --pidfile pidfile
may be invoked with the following command line options:
- 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
Privoxy process that the directory tree starts there. If set up
carefully, this can limit the impact of possible vulnerabilities in
Privoxy to the files contained in that hierarchy.
- 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.
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).
This option doesn't affect the log setting, combination with
"--no-daemon" is recommended if a configured log file shouldn't
- Print brief usage info and exit.
- 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
- --pidfile pidfile
- On startup, write the process ID to pidfile. Delete
the pidfile on exit. Failure to create or delete the pidfile
is non-fatal. If no --pidfile option is given, no PID file will be
- --pre-chroot-nslookup hostname
- Initialize the resolver library using hostname
before chroot'ing. On some systems this reduces the number of files that
must be copied into the chroot tree.
- --user user[.group]
- After (optionally) writing the PID file, assume the user ID
of user and the GID of group, or, if the optional
group was not given, the default group of user. Exit if the
privileges are not sufficient to do so.
- Print version info and exit.
If the configfile
is not specified on the command line, Privoxy
will look for a file named config
in the current directory. If no
is found, Privoxy
will fail to start.
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
Privoxy is Free Software and licensed under the GNU GPLv2.
Privoxy is an associated project of Software in the Public Interest (SPI).
Helping hands and donations are welcome:
Browsers can either be individually configured to use Privoxy
as a HTTP
proxy (recommended), or Privoxy
can be combined with a packet filter to
build an intercepting proxy (see config
). The default setting is for
localhost, on port 8118 (configurable in the main config file). To set the
HTTP proxy in Firefox, go through: Tools
; Connection Settings
; Manual Proxy Configuration
For Internet Explorer, go through: Tools
; Internet Properties
; LAN Settings
The Secure (SSL) Proxy should also be set to the same values, otherwise https:
URLs will not be proxied. Note: Privoxy
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.
For other browsers, check the documentation.
can be configured with the various configuration files. The
default configuration files are: config
used for locally defined exceptions to the default rules in
, and user.filter
locally defined filters. These are well commented. On Unix and Unix-like
systems, these are located in /etc/privoxy/
uses the concept of actions
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.
The actions list (ad blocks, etc) can also be configured with your web browser
at http://config.privoxy.org/ (assuming the configuration allows it).
configuration parameters can also be viewed at the same page.
In addition, Privoxy
can be toggled on/off. This is an internal page,
and does not require Internet access.
See the User Manual
for a detailed explanation of installation, general
usage, all configuration options, new features and notes on upgrading.
Various other files should be included, but may vary depending on platform and
build configuration. Additional documentation should be included in the local

ones listed above aren't explicitly handled and result in the default action
defined by the operating system.
