Hammer & Screwdriver traceroute
traceroute shows you the route packets take to reach the destination address. it shows you the hops or router packets goes through before reaching destination address.

Give it an Ip to follow. Say from your UNIX box to your laptop. it will show you the path it takes to get there.

Pretty good for diagnostic checking of Network problems.

That doesn't matter. Just run traceroute from any UNIX system to any other IP address. It will work. However, their may be some firewall issues or if you are on a private network it may not be able to complete.

For the most part, it should work.

It may very well be a network-design issue (ie firewalling, etc).

From the man page on traceroute:
Quote:
This program attempts to trace the route an IP packet would follow to
some internet host by launching UDP probe packets with a small ttl (time
to live) then listening for an ICMP "time exceeded" reply from a gateway.
We start our probes with a ttl of one and increase by one until we get an
ICMP "port unreachable" (which means we got to "host") or hit a max
(which defaults to 30 hops & can be changed with the -m flag).
Therefore, if your net admin restricts UDP in any direction, or ICMP in any direction, you may very well be impacted by this...
