24) <br />
25) 
26) <p>
27) The latest release of Tor can be found on the <a
28) href="<page download>">download</a> page. We have packages for Debian,
29) Red Hat, Gentoo, *BSD, etc there too.
30) </p>
31) 
32) <p>If you're building from source, first install <a
33) href="http://www.monkey.org/~provos/libevent/">libevent</a>, and
34) make sure you have openssl and zlib (including the -devel packages if

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

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

51) <br />
52) 
53) <p>After installing Tor, you need to configure your applications to use it.
54) </p>
55) 
56) <p>
57) The first step is to set up web browsing. Start by installing <a
58) href="http://www.privoxy.org/">Privoxy</a>: click on 'recent releases'
59) and pick your favorite package or install from source. Privoxy is a
60) filtering web proxy that integrates well with Tor.
61) </p>
62) 

63) <p>Once you've installed Privoxy (either from package or from source),
64) <b>you will need to configure Privoxy to use Tor</b>.

65) Open Privoxy's "config" file (look in /etc/privoxy/ or /usr/local/etc/)
66) and add the line <br>

67) <tt>forward-socks4a / 127.0.0.1:9050 .</tt><br>

68) to the top of the config file. Don't forget to add the dot at the end.
69) </p>
70) 
71) <p>Privoxy keeps a log file of everything passed through it.  In

72) order to stop this you will need to comment out three lines by inserting a
73) \# before the line. The three lines are:<br>

74) <tt>logfile logfile</tt><br>
75) and the line <br>
76) <tt>jarfile jarfile</tt><br>

77) and (on some systems) the line <br>
78) <tt>debug 1  # show each GET/POST/CONNECT request</tt><br>

79) </p>
80) 

81) <p>Depending on which default config file you have for Privoxy,
82) you may also need to turn off <tt>enable-remote-toggle</tt>,
83) <tt>enable-remote-http-toggle</tt>, and <tt>enable-edit-actions</tt>.
84) </p>
85) 

86) <p>You'll need to restart Privoxy for the changes to take effect.</p>

91) <br />
92) 
93) <p>After installing Tor and Privoxy, you need to configure your
94) applications to use them. The first step is to set up web browsing.</p>
95) 

96) <p>If you're using Firefox (we recommend it), simply install the <a

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

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

109) Torbutton here</a>.
110) If you plan to run Firefox on a different computer than Tor, see the <a

111) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SocksListenAddress">
112) FAQ
113) entry for running Tor on a different computer</a>. If you need to
114) use a browser other than Firefox, you'll have to <a href="<page
115) docs/tor-doc-web>">configure its proxy settings yourself</a>.)
116) </p>

117) 
118) <p>Using privoxy is <strong>necessary</strong> because <a
119) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">browsers
120) leak your DNS requests when they use a SOCKS proxy directly</a>, which
121) is bad for your anonymity. Privoxy also removes certain dangerous
122) headers from your web requests, and blocks obnoxious ad sites like
123) Doubleclick.</p>
124) 
125) <p>To Torify other applications that support HTTP proxies, just
126) point them at Privoxy (that is, localhost port 8118). To use SOCKS
127) directly (for instant messaging, Jabber, IRC, etc), you can point
128) your application directly at Tor (localhost port 9050), but see <a
129) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">this
130) FAQ entry</a> for why this may be dangerous. For applications
131) that support neither SOCKS nor HTTP, take a look at <a
132) href="http://tsocks.sourceforge.net/">tsocks</a> or <a

144) <br />
145) 
146) <p>
147) Next, you should try using your browser with Tor and make

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

149) <a href="http://torcheck.xenobite.eu/">the

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

155) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#IsMyConnectionPrivate">this
156) FAQ entry</a> for more suggestions on how to test your Tor.)
157) </p>
158) 
159) <p>If you have a personal firewall that limits your computer's
160) ability to connect to itself (this includes something like SELinux on
161) Fedora Core 4), be sure to allow connections from
162) your local applications to Privoxy (local port 8118) and Tor (local port
163) 9050). If
164) your firewall blocks outgoing connections, punch a hole so
165) it can connect to at least TCP ports 80 and 443, and then see <a
166) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#FirewalledClient">this
167) FAQ entry</a>.  If your SELinux config is not allowing tor or privoxy to
168) run correctly, create a file named booleans.local in the directory
169) /etc/selinux/targeted.  Edit this file in your favorite text editor and
170) insert "allow_ypbind=1".  Restart your machine for this change to take
171) effect.

182) <br />
183) 
184) <p>The Tor network relies on volunteers to donate bandwidth. The more

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

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

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

188) and convenient, including rate limiting for bandwidth, exit policies so
189) you can limit your exposure to abuse complaints, and support for dynamic
190) IP addresses.</p>
191) 

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

193) makes Tor users secure. <a

194) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#RelayAnonymity">You

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