The Traceroute 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.

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