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

<para>Install <application>Traceroute</application> by running the following
|
|
commands:</para>
|
|
|
|
<screen><userinput><command>sed -i -e 's/-o bin/-o root/' Makefile.in &&
|
|
./configure --prefix=/usr &&
|
|
make</command></userinput></screen>
|
|
|
|
<para>Now, as the root user:</para>

<screen><userinput role='root'><command>make install &&
|
|
make install-man</command></userinput></screen>

|
|
|
|
<para><command>sed 's/-o bin/-o root/' Makefile.in</command>:
|
|
Adjusts the <filename>Makefile</filename> so that the program is installed
|
|
with user root instead of user bin (which doesn't exist on a default
|
|
<acronym>LFS</acronym> system).</para>
|
|
|
|
<para><command>make install</command>: Installs <command>traceroute</command>
|
|
with <acronym>SUID</acronym> set to root in the
|
|
<filename class='directory'>/usr/sbin</filename> directory. This makes it
|
|
possible for all users to execute <command>traceroute</command>. For absolute
|
|
security, turn off the <acronym>SUID</acronym> bit in
|
|
<command>traceroute</command>'s file permissions with the command:</para>
|
|
|
|
<screen><userinput role='root'><command>chmod 0755 /usr/sbin/traceroute</command></userinput></screen>
|
|
|
|
<para>The risk is that if a security problem such as a buffer overflow was
|
|
ever found in the <application>Traceroute</application> code, a regular user
|
|
on your system could gain root access if the program is
|
|
<acronym>SUID</acronym> root. Of course, removing
|
|
the <acronym>SUID</acronym> permission also makes it impossible for users other
|
|
than root to utilize <command>traceroute</command>, so decide what's right for
|
|
your individual situation.</para>
|
|
|
|
<para>The goal of <acronym>BLFS</acronym> is to be completely
|
|
<acronym>FHS</acronym> compliant, so if you do leave the
|
|
<command>traceroute</command> binary <acronym>SUID</acronym> root, then you
|
|
should move <filename>traceroute</filename> to
|
|
<filename class='directory'>/usr/bin</filename> with the following command:
|
|
</para>
|
|
|
|
<screen><userinput role='root'><command>mv /usr/sbin/traceroute /usr/bin</command></userinput></screen>
|
|
|
|
<para>This ensures that the binary is in the path for non-root users.</para>
