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

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

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

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

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

64) Open Privoxy's "config" file (look in /etc/privoxy/ or /usr/local/etc/)
65) and add the line <br>
66) <tt>forward-socks4a / localhost:9050 .</tt><br>
67) to the top of the config file. Don't forget to add the dot at the end.
68) </p>
69) 
70) <p>Privoxy keeps a log file of everything passed through it.  In
71) order to stop this you will need to comment out two lines by inserting a

72) \# before the line. The two lines are:<br>

73) <tt>logfile logfile</tt><br>
74) and the line <br>
75) <tt>jarfile jarfile</tt><br>
76) </p>
77) 
78) <p>You'll need to restart Privoxy for the changes to take effect.</p>

83) <br />
84) 
85) <p>After installing Tor and Privoxy, you need to configure your
86) applications to use them. The first step is to set up web browsing.</p>
87) 

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

89) href="http://freehaven.net/~squires/torbutton/">Torbutton

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

93) <img alt="Torbutton plugin for Firefox"
94) src="../img/screenshot-torbutton.png"
95) border="1">

96) 
97) <p>

98) (If you plan to run Firefox on a different computer than Tor, see the <a
99) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SocksListenAddress">
100) FAQ
101) entry for running Tor on a different computer</a>. If you need to
102) use a browser other than Firefox, you'll have to <a href="<page
103) docs/tor-doc-web>">configure its proxy settings yourself</a>.)
104) </p>

105) 
106) <p>Using privoxy is <strong>necessary</strong> because <a
107) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">browsers
108) leak your DNS requests when they use a SOCKS proxy directly</a>, which
109) is bad for your anonymity. Privoxy also removes certain dangerous
110) headers from your web requests, and blocks obnoxious ad sites like
111) Doubleclick.</p>
112) 
113) <p>To Torify other applications that support HTTP proxies, just
114) point them at Privoxy (that is, localhost port 8118). To use SOCKS
115) directly (for instant messaging, Jabber, IRC, etc), you can point
116) your application directly at Tor (localhost port 9050), but see <a
117) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">this
118) FAQ entry</a> for why this may be dangerous. For applications
119) that support neither SOCKS nor HTTP, take a look at <a
120) href="http://tsocks.sourceforge.net/">tsocks</a> or <a
121) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorifyHOWTO#socat">socat</a>.

132) <br />
133) 
134) <p>
135) Next, you should try using your browser with Tor and make
136) sure that your IP address is being anonymized. Click on the <a
137) href="http://serifos.eecs.harvard.edu/cgi-bin/ipaddr.pl?tor=1">Tor
138) detector</a> and see whether it thinks you're using Tor or not.
139) (If that site is down, see <a
140) href="http://wiki.noreply.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 Privoxy (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="http://wiki.noreply.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.

165) <h2><a class="anchor" href="#server">Step Five: Configure it as a server</a></h2>
166) <br />
167) 
168) <p>The Tor network relies on volunteers to donate bandwidth. The more
169) people who run servers, the faster the Tor network will be. If you have
170) at least 20 kilobytes/s each way, please help out Tor by configuring your
171) Tor to be a server too. We have many features that make Tor servers easy
172) and convenient, including rate limiting for bandwidth, exit policies so
173) you can limit your exposure to abuse complaints, and support for dynamic
174) IP addresses.</p>
175) 
176) <p>Having servers in many different places on the Internet is what
177) makes Tor users secure. <a
178) href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#ServerAnonymity">You
179) may also get stronger anonymity yourself</a>,
180) since remote sites can't know whether connections originated at your
181) computer or were relayed from others.</p>
