larger than or equal to 32 bytes. For smaller probe packets, keep using SHUTDOWN-ACK chunks, possibly bundled with a PAD chunk. Packets with INIT chunks more likely pass through firewalls. Therefore, use them when possible. MFC after: 1 week |

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).

contributions, etc., should be sent to the email address
