linux下使用tcp来traceroute的东西,是静态RPM版本,十分好安装,tgz的包安装的时候要依赖几个其他的包的。另外此程序在windows下也有相应的实现,cain就可以,然后命令行下的有一个叫tracetcp的东西,他们都需要winpcap包。
这个东西是检查网络故障的好工具。

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.
