On mac, lsof says a port is not in use, but I can telnet to the port

If I run lsof, it says that this port is not in use. Yet, I can telnet into it and something is listening on that port.

Am I using the wrong command to see what ports are in use? I'd like to kill the process listening on 3306.

±  |master ✓| → lsof -i :3306

±  |master ✓| → telnet localhost 3306

Solution

  • To check which process is running on 3306 port sudo lsof -i tcp:3306 and if you get the process id kill -9
