-+Description: Traces the route taken by packets over a TCP/IP network.
-+ 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.
-+ .
-+ Install traceroute if you need a tool for diagnosing network connectivity
-+ problems.
