9Traceroute is a system administrators utility to trace the route
10ip packets from the current system take in getting to some
11destination system. See the comments at the front of the
12program for a description of its use.
13
14This program uses raw ip sockets and must be run as root (or installed
15setuid to root).
16
17A couple of awk programs to massage the traceroute output are
18included. "mean.awk" and "median.awk" compute the mean and median time
19to each hop, respectively. I've found that something like
20
21 traceroute -q 7 foo.somewhere >t

25usually a better noise filter than mean).
