推荐答案

要获取打开的连接列表，可以使用netstat命令.与(其他答案)普遍认为的相反，临时端口的数量有限(在Windows 2003上为4000，在更高版本上为16000，在大多数Linux上为16000).还要注意，一旦不使用端口，释放端口要花费4分钟，因此这确实是一个问题.

To get list of open connection you may use netstat command. Contrary to popular believe (of other answers) number of Ephemeral ports is limited (4000 on Windows 2003, some 16000 on later versions, 16000 on most Linuxes). Note also that it take 4 minutes to release port once it become unused therefore it really can be an issue.
