|
---|
| 21 | <para>The <application>Traceroute</application> package contains a program
|
---|
| 22 | which is used to display the network route that packets take to reach a
|
---|
| 23 | specified host. This is a standard network troubleshooting tool. If you find
|
---|
| 24 | yourself unable to connect to another system, traceroute can help pinpoint
|
---|
| 25 | the problem.</para>

| 61 | Adjusts the <filename>Makefile</filename> so that the program is installed
|
---|
| 62 | with user root instead of user bin (which doesn't exist on a default
|
---|
| 63 | <acronym>LFS</acronym> system).</para>
|
---|
| 64 |
|
---|
| 65 | <para><command>make install</command>: Installs <command>traceroute</command>
|
---|
| 66 | with <acronym>SUID</acronym> set to root in the <filename>/usr/sbin</filename> directory. This makes it
|
---|
| 67 | possible for all users to execute <command>traceroute</command>. For absolute
|
---|
| 68 | security, turn off the <acronym>SUID</acronym> bit in <command>traceroute</command>'s file
|
---|
| 69 | permissions with the command:</para>
|
---|
| 70 | <screen><command>chmod 0755 /usr/sbin/traceroute</command></screen>
|
---|
| 71 |
|
---|
| 72 | <para>The risk is that if a security problem such as a buffer overflow was
|
---|
| 73 | ever found in the <application>Traceroute</application> code, a regular user
|
---|
| 74 | on your system could gain root access if the program is
|
---|
| 75 | <acronym>SUID</acronym> root. Of course, removing
|
---|
| 76 | the <acronym>SUID</acronym> permission also makes it impossible for users other than
|
---|
| 77 | root to utilize <command>traceroute</command>, so decide what's right for your
|
---|
| 78 | individual situation.</para>
|
---|
| 79 |
|
---|
| 80 | <para>Our aim is to be completely <acronym>FHS</acronym> compliant, so if
|
---|
| 81 | you do leave the <command>traceroute</command> binary
|
---|
| 82 | <acronym>SUID</acronym> root, then you
|
---|
| 83 | should move <filename>traceroute</filename> to <filename>/usr/bin</filename>
|
---|
| 84 | with the following command:</para>
|
---|
| 85 | <screen><command>mv /usr/sbin/traceroute /usr/bin</command></screen>
|
---|
| 86 |
|
---|
| 87 | <para>This ensures that the binary is in the path for non-root users.</para>
