检查 Mac 上打开的 TCP 连接

Question

什么是 Mac 等效的 TCPView 或 CurrPorts？我以前从未使用过Mac，所以我一无所知。

Answer 1

netstat 和 lsof 都会这样做：

$ netstat -an | grep -i "listen"
tcp4       0      0  *.88                   *.*                    LISTEN
tcp6       0      0  *.88                   *.*                    LISTEN
tcp4       0      0  127.0.0.1.29746        *.*                    LISTEN
tcp46      0      0  *.5900                 *.*                    LISTEN
tcp4       0      0  *.22                   *.*                    LISTEN
tcp6       0      0  *.22                   *.*                    LISTEN
tcp4       0      0  *.548                  *.*                    LISTEN
tcp6       0      0  *.548                  *.*                    LISTEN
tcp4       0      0  127.0.0.1.631          *.*                    LISTEN
tcp6       0      0  ::1.631                *.*                    LISTEN

$ sudo lsof -i -P | grep -i "listen"
launchd       1           root   18u  IPv6 0x08871e20      0t0    TCP localhost:631 (LISTEN)

如果你不喜欢命令行，你也可以自己进行端口扫描（运行网络实用程序，转到端口扫描选项卡，输入 localhost 并点击“扫描”）。
