NAME
tctrace - similar to traceroute, yet uses TCP SYN packets
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 timout 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.
