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.
