26) <p>
27) The latest release of Tor can be found on the <a

28) href="<page download-unix>">download</a> page. We have packages for Debian,
29) Red Hat, Gentoo, *BSD, etc there too. If you're
30) using Ubuntu, don't use the default packages: use <a

31) href="<page docs/debian>#ubuntu">our deb repository</a> instead.

32) </p>
33) 
34) <p>If you're building from source, first install <a
35) href="http://www.monkey.org/~provos/libevent/">libevent</a>, and
36) make sure you have openssl and zlib (including the -devel packages if

37) applicable). Then run:<br />
38) <tt>tar xzf tor-<version-stable>.tar.gz; cd tor-<version-stable><br />
39) ./configure &amp;&amp; make</tt><br />
40) Now you can run tor as <tt>src/or/tor</tt>, or you can run <tt>make install</tt>

41) (as root if necessary) to install it into /usr/local/, and then you can
42) start it just by running <tt>tor</tt>.
43) </p>
44) 
45) <p>Tor comes configured as a client by default. It uses a built-in
46) default configuration file, and most people won't need to change any of
47) the settings. Tor is now installed.

55) 
56) <p>After installing Tor, you need to configure your applications to use it.
57) </p>
58) 
59) <p>
60) The first step is to set up web browsing. Start by installing <a

61) href="http://www.pps.jussieu.fr/~jch/software/polipo/">Polipo</a> from
62) your favorite repository. Polipo is a caching web proxy that does http

63) pipelining well, so it's well-suited for Tor's latencies. Make sure

64) to get at least Polipo 1.0.4, since earlier versions lack the SOCKS support

65) required to use Polipo with Tor.

66) </p>
67) 

68) <p>Once you've installed Polipo (either from package or from
69) source), <b>you will need to configure Polipo to use Tor</b>. Grab our <a
70) href="https://svn.torproject.org/svn/torbrowser/trunk/build-scripts/config/polipo.conf">Polipo
71) configuration for Tor</a> and put it in place of your current polipo

72) config file (e.g. /etc/polipo/config or ~/.polipo).

73) You'll need to restart Polipo for the changes to take effect. For
74) example:<br />

75) <tt>/etc/init.d/polipo restart</tt>

76) </p>

77) 

78) <p>If you prefer, you can instead use Privoxy with <a
79) href="https://wiki.torproject.org/noreply/TheOnionRouter/PrivoxyConfig">this
80) sample Privoxy configuration</a>. But since the config files both use
81) port 8118, you shouldn't run both Polipo and Privoxy at the same time.</p>

88) <p>After installing Tor and Polipo, you need to configure your

89) applications to use them. The first step is to set up web browsing.</p>
90) 

91) <p>You should use Tor with Firefox and Torbutton, for best safety.
92) Simply install the <a

93) href="https://addons.mozilla.org/firefox/2275/">Torbutton

94) plugin</a>, restart your Firefox, and you're all set:

104) If you plan to run Firefox on a different computer than Tor, see the <a

105) href="https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#SocksListenAddress">

106) FAQ

107) entry for running Tor on a different computer</a>.

108) </p>

109) 
110) <p>To Torify other applications that support HTTP proxies, just

111) point them at Polipo (that is, localhost port 8118). To use SOCKS

112) directly (for instant messaging, Jabber, IRC, etc), you can point
113) your application directly at Tor (localhost port 9050), but see <a

114) href="https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">this

115) FAQ entry</a> for why this may be dangerous. For applications
116) that support neither SOCKS nor HTTP, take a look at <a
117) href="http://tsocks.sourceforge.net/">tsocks</a> or <a

131) <p>
132) Next, you should try using your browser with Tor and make

133) sure that your IP address is being anonymized. Click on

134) <a href="https://check.torproject.org/">the

135) Tor detector</a>
136) and see whether it thinks you're using Tor or not.
137) #<a href="http://ipchicken.com/">this site</a>
138) #to see what IP address it thinks you're using.

140) href="https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#IsMyConnectionPrivate">this

141) FAQ entry</a> for more suggestions on how to test your Tor.)
142) </p>
143) 
144) <p>If you have a personal firewall that limits your computer's
145) ability to connect to itself (this includes something like SELinux on
146) Fedora Core 4), be sure to allow connections from

147) your local applications to Polipo (local port 8118) and Tor (local port

148) 9050). If
149) your firewall blocks outgoing connections, punch a hole so
150) it can connect to at least TCP ports 80 and 443, and then see <a

151) href="https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#FirewalledClient">this

152) FAQ entry</a>.  If your SELinux config is not allowing tor or privoxy to
153) run correctly, create a file named booleans.local in the directory
154) /etc/selinux/targeted.  Edit this file in your favorite text editor and
155) insert "allow_ypbind=1".  Restart your machine for this change to take
156) effect.

166) <h2><a class="anchor" href="#relay">Step Five: Configure it as a relay</a></h2>

167) <br />
168) 
169) <p>The Tor network relies on volunteers to donate bandwidth. The more

170) people who run relays, the faster the Tor network will be. If you have

171) at least 20 kilobytes/s each way, please help out Tor by configuring your

172) Tor to be a relay too. We have many features that make Tor relays easy

173) and convenient, including rate limiting for bandwidth, exit policies so
174) you can limit your exposure to abuse complaints, and support for dynamic
175) IP addresses.</p>
176) 

177) <p>Having relays in many different places on the Internet is what

178) makes Tor users secure. <a

179) href="https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#RelayAnonymity">You

180) may also get stronger anonymity yourself</a>,
181) since remote sites can't know whether connections originated at your
182) computer or were relayed from others.</p>
