Traceroute

Traceroute is a program that tracks the path of data between two points. In this case, it tracks the path of data from our server, to your computer. This can be a great way to analyze your internet connection to find out if there is a problem somewhere.

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. Three probes are sent at each ttl setting and a line is printed showing the ttl, address of the gateway and round trip time of each probe. If the probe answers come from different gateways, the address of each responding system will be printed. If there is no response within a 5 sec. timeout interval, a "*" is printed for that probe.
