23<title>Introduction to <application>Traceroute</application></title>
24
25<para>The <application>Traceroute</application> package contains a program
26which is used to display the network route that packets take to reach a
27specified host. This is a standard network troubleshooting tool. If you find
28yourself unable to connect to another system, traceroute can help pinpoint
29the problem.</para>

62
63<para><command>sed 's/-o bin/-o root/' Makefile.in</command>:
64Adjusts the <filename>Makefile</filename> so that the program is installed
65with user root instead of user bin (which doesn't exist on a default
66<acronym>LFS</acronym> system).</para>
67
68<para><command>make install</command>: Installs <command>traceroute</command>
69with <acronym>SUID</acronym> set to root in the <filename>/usr/sbin</filename>
70directory. This makes it possible for all users to execute
71<command>traceroute</command>. For absolute security, turn off the
72<acronym>SUID</acronym> bit in <command>traceroute</command>'s file permissions
73with the command:</para>
74<screen><command>chmod 0755 /usr/sbin/traceroute</command></screen>
75
76<para>The risk is that if a security problem such as a buffer overflow was
77ever found in the <application>Traceroute</application> code, a regular user
78on your system could gain root access if the program is
79<acronym>SUID</acronym> root. Of course, removing
80the <acronym>SUID</acronym> permission also makes it impossible for users other
81than root to utilize <command>traceroute</command>, so decide what's right for
82your individual situation.</para>
83
84<para>The goal of <acronym>BLFS</acronym> is to be completely
85<acronym>FHS</acronym> compliant, so if you do leave the
86<command>traceroute</command> binary <acronym>SUID</acronym> root, then you
87should move <filename>traceroute</filename> to
88<filename class='directory'>/usr/bin</filename> with the following command:
89</para>
90<screen><command>mv /usr/sbin/traceroute /usr/bin</command></screen>
91
92<para>This ensures that the binary is in the path for non-root users.</para>

108route your packets take from the host you are working on to another host on a
109network, showing all the intermediate hops (gateways) along the way.</para>
