in http://www.iana.org/assignments/icmp-parameters. Thankfully IANA's list aggrees with <netinet/ip_icmp.h>. I've tried to do this in a way which is mostly consistent with tcptraceroute and Debian's version of traceroute. However, sometimes a letter is used twice by these versions, so I've gone with: LBL tcptr Debian (chosen) ICMP_UNREACH_NET !N !N !N !N ICMP_UNREACH_HOST !H !H !H !H ICMP_UNREACH_PROTOCOL !P !P !P !P ICMP_UNREACH_PORT ! !p ! !

TRACEROUTE 1.4

Traceroute is a system administrators utility to trace the route
ip packets from the current system take in getting to some
destination system. See the comments at the front of the
program for a description of its use.
This program uses raw ip sockets and must be run as root (or installed
setuid to root).
A couple of awk programs to massage the traceroute output are
included. "mean.awk" and "median.awk" compute the mean and median time
to each hop, respectively. I've found that something like
traceroute -q 7 foo.somewhere >t
awk -f median.awk t | xgraph
can give you a quick picture of the bad spots on a long path (median is
usually a better noise filter than mean).
Problems, bugs, questions, desirable enhancements, source code
contributions, etc., should be sent to the email address
"traceroute@ee.lbl.gov".
