DESCRIPTION

This manual page documents briefly the tctrace command. This manual page was written for the Debian distribution because the original program does not have a manual page.

TCtrace is like itrace a traceroute(1) brother - but it uses TCP SYN packets to trace.

This makes it possible for you to trace through firewalls if you know one TCP service that is allowed to pass from the outside.

Typical Usage:

tctrace -i eth0 -d www.phenoelit.de

-v verbose

-n reverse lookup answering IPs (slow!)

-p x send x probes per hop (default=3)

-m x set TTL max to x (default=30)

-t x timeout after x seconds (default=3)

-D x destination port x (default=80)

-S x source port x (default=1064)

-i interface the normal eth0 stuff

-d destination Name or IP of destination

Note there have been bugs reported on tctrace. It sometimes has a mind of its own.
