"traceroute -P tcp"...? :-)
The modern BSD traceroute supports all of:
-P Send packets of specified IP protocol. The currently
supported
protocols are: UDP, TCP, GRE and ICMP. Other
protocols may also
be specified (either by name or by number), though
traceroute
does not implement any special knowledge of their
packet for-
mats. This option is useful for determining which
router along a
path may be blocking packets based on IP protocol
number. But
see BUGS below.
