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. - -WWW: http://michael.toren.net/code/tcptraceroute/ - -- Simon 'corecode' Schubert |
