tcptraceroute is a traceroute implementation using TCP packets.
The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination.

By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters. You learn something new every day. Interesting. That could come in very handy.  |
Yes. I posted that same link a few pages back!
The same functionality is now integrated into recent versions of traceroute though. You just need to use the -T option and set the destination port with -p

There is evidence that squirrelmail is used on over 117,000 sites! That's an awful lot of webmail sites phorm is still to exclude.
