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.

The problem is  that with the widespread use of  firewalls on the modern

Internet, many of the packets that  traceroute(8) sends out end up being

filtered,  making it  impossible to  completely  trace the  path to  the

destination. However, in many cases, these firewalls will permit inbound

TCP packets to specific ports that hosts sitting behind the firewall are

listening for connections on. By sending  out TCP SYN packets instead of

UDP  or ICMP  ECHO packets,  tcptraceroute is  able to  bypass the  most

common firewall filters.
