如何显示端口的侦听端口和TCP连接

有谁知道Ubuntu Server中用于显示的确切netstat命令：

• 在服务器上侦听的端口
• 当前与这些端口的TCP连接

Answer 1

尝试

 netstat --tcp --listen --numeric-ports 

防爆。

 $ netstat --tcp --listen --numeric-ports Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN tcp 0 0 127.0.1.1:53 0.0.0.0:* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 ::1:631 :::* LISTEN tcp6 0 0 ::1:6010 :::* LISTEN 

和

 netstat --tcp --numeric-ports 

防爆。

 $ netstat --tcp --numeric-ports Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 272 192.168.1.11:22 192.168.1.3:43444 ESTABLISHED tcp 0 0 192.168.1.11:22 192.168.1.2:65370 ESTABLISHED tcp 0 0 192.168.1.11:22 192.168.1.2:65369 ESTABLISHED
