Activity Monitor on Mac OS doesn't show port 8080 I'm trying to verify that a specified process (server) listens on port 8080 using Activity Monitor. But, for some strange reason, Activity Monitor doesn't show information about port numbers greater than 25XX. I do know that the server works fine and listens on this port.

How can I see the process which listens on port 8080 in Activity Monitor?
You can't do it easily in Activity Monitor but it is easy at the command line. lsof -i :8080 in the Terminal will display the command and process ID of the process listening on port 8080.
