24<title>Introduction to <application>Ethereal</application></title>
25
26<para>The <application>Ethereal</application> package contains a network
27protocol analyzer, also known as a <quote>sniffer</quote>. This is useful for
28analyzing data captured <quote>off the wire</quote> from a live network
29connection, or data read from a capture file.
30<application>Ethereal</application> provides both <acronym>GUI</acronym> and
31<acronym>TTY</acronym>-mode programs for examining captured network packets
32from over 500 protocols, as well as the capability to read capture files from
33many other popular network analyzers.</para>

109<para>Though the default configuration parameters are very sane,
110reference the configuration section of the
111<ulink url="http://www.ethereal.com/docs/user-guide/">Ethereal User's
112Guide</ulink> for configuration information. Most of
113<application>Ethereal</application>'s configuration can be accomplished
114using the menu options of the <command>ethereal</command>
115<acronym>GUI</acronym> interface.</para>

117
118<sect4><title>Kernel configuration</title>
119<para>The kernel must have the Packet protocol enabled for
120<application>Ethereal</application> to capture live packets from the network.
121Enable the Packet protocol by choosing <quote>Y</quote> in the
122<quote>Device Drivers</quote> &ndash; <quote>Networking support</quote>
123&ndash; <quote>Networking options</quote> &ndash; <quote>Packet socket</quote>
124configuration parameter. Alternatively, build the af_packet module by choosing
125<quote>M</quote> in this parameter.</para>
126
127<para>Note: If you want to look at packets, make sure you don't filter
128them out with <xref linkend="iptables"/>. If you want to exclude
129certain classes of packets, it is more efficient to do it with
130<application>iptables</application> than
131<application>Ethereal</application>.</para>
