Description:

The traceroute utility displays the route used by IP packets on their
way to a specified network (or Internet) host. Traceroute displays
the IP number and host name (if possible) of the machines along the
route taken by the packets. Traceroute is used as a network debugging
tool. If you're having network connectivity problems, traceroute will
show you where the trouble is coming from along the route.

This is a small traceroute replacement that works without requiring a
setuid bit. It is written by Olaf Kirch, and relies on a number of features
introduced in the Linux 2.4 kernel, especially the ability to obtain raw
ICMP error information from a UDP socket.
