Traceroute

Simple ICMP traceroute

About

Traceroute shows a path through the Internet from your computer to a specified address. This implementation uses ICMP packages and raw sockets. Only paths up to specified limit of steps (32 by default) are recognized.

Output format

When there are replies for any of the requests sent, then reply addresses are displayed with their reply times and average reply time at the end:

<step>. <reply address> -- <reply times> [/ <reply address> -- <reply times>...] (avg <average reply time>)

When there are no replies, then a single asterisk character is displayed:

<step>. *
