29)     The latest release of Tor can be found on the <a
30)     href="<page download/download>">download</a> page. We have packages for Debian,
31)     Red Hat, Gentoo, *BSD, etc there too. If you're
32)     using Ubuntu, don't use the default packages: use <a
33)     href="<page docs/debian>#ubuntu">our deb repository</a> instead.

34)     Similarly, CentOS / Fedora / OpenSUSE users should use <a href="<page
35)     docs/rpms>">our rpm repository</a> instead.

36)     </p>
37)     
38)     <p>If you're building from source, first install <a
39)     href="http://www.monkey.org/~provos/libevent/">libevent</a>, and
40)     make sure you have openssl and zlib (including the -devel packages if

41)     applicable). Then run:<br>
42)     <tt>tar xzf tor-<version-stable>.tar.gz; cd tor-<version-stable></tt><br>
43)     <tt>./configure &amp;&amp; make</tt><br>

44)     Now you can run tor as <tt>src/or/tor</tt>, or you can run <tt>make install</tt>
45)     (as root if necessary) to install it into /usr/local/, and then you can
46)     start it just by running <tt>tor</tt>.
47)     </p>
48)     
49)     <p>Tor comes configured as a client by default. It uses a built-in
50)     default configuration file, and most people won't need to change any of
51)     the settings. Tor is now installed.

60)     <p>After installing Tor, you need to configure your applications to use it.
61)     </p>
62)     
63)     <p>
64)     The first step is to set up web browsing. Start by installing <a
65)     href="http://www.pps.jussieu.fr/~jch/software/polipo/">Polipo</a> from
66)     your favorite repository. Polipo is a caching web proxy that does http
67)     pipelining well, so it's well-suited for Tor's latencies. Make sure
68)     to get at least Polipo 1.0.4, since earlier versions lack the SOCKS support
69)     required to use Polipo with Tor. You should uninstall privoxy at this
70)     point (e.g. apt-get remove privoxy or yum remove privoxy), so they don't
71)     conflict.
72)     </p>
73)     
74)     <p>Once you've installed Polipo (either from package or from
75)     source), <b>you will need to configure Polipo to use Tor</b>. Grab our <a

76)     href="<tbbrepo>/build-scripts/config/polipo.conf">Polipo

77)     configuration for Tor</a> and put it in place of your current polipo
78)     config file (e.g. /etc/polipo/config or ~/.polipo).
79)     You'll need to restart Polipo for the changes to take effect. For

80)     example:<br>

81)     <tt>/etc/init.d/polipo restart</tt>
82)     </p>
83)     
84)     <p>If you prefer, you can instead use Privoxy with <a

85)     href="<wiki>doc/PrivoxyConfig">this

86)     sample Privoxy configuration</a>. But since the config files both use
87)     port 8118, you shouldn't run both Polipo and Privoxy at the same time.</p>

93)     
94)     <p>After installing Tor and Polipo, you need to configure your
95)     applications to use them. The first step is to set up web browsing.</p>
96)     
97)     <p>You should use Tor with Firefox and Torbutton, for best safety.
98)     Simply install the <a

99)     href="<page torbutton/index>">Torbutton

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

113)     entry for running Tor on a different computer</a>.
114)     </p>
115)     
116)     <p>To Torify other applications that support HTTP proxies, just
117)     point them at Polipo (that is, localhost port 8118). To use SOCKS
118)     directly (for instant messaging, Jabber, IRC, etc), you can point
119)     your application directly at Tor (localhost port 9050), but see <a

120)     href="<wikifaq>#SOCKSAndDNS">this

121)     FAQ entry</a> for why this may be dangerous. For applications
122)     that support neither SOCKS nor HTTP, take a look at <a

137)     <p>
138)     Next, you should try using your browser with Tor and make
139)     sure that your IP address is being anonymized. Click on
140)     <a href="https://check.torproject.org/">the
141)     Tor detector</a>
142)     and see whether it thinks you're using Tor or not.

149)     
150)     <p>If you have a personal firewall that limits your computer's
151)     ability to connect to itself (this includes something like SELinux on
152)     Fedora Core 4), be sure to allow connections from
153)     your local applications to Polipo (local port 8118) and Tor (local port
154)     9050). If
155)     your firewall blocks outgoing connections, punch a hole so
156)     it can connect to at least TCP ports 80 and 443, and then see <a

157)     href="<wikifaq>#FirewalledClient">this

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

176)     people who run relays, the faster the Tor network will be. If you have
177)     at least 20 kilobytes/s each way, please help out Tor by configuring your
178)     Tor to be a relay too. We have many features that make Tor relays easy
179)     and convenient, including rate limiting for bandwidth, exit policies so
180)     you can limit your exposure to abuse complaints, and support for dynamic
181)     IP addresses.</p>
