Macos List Process Using Port

List all files using any protocol on ports 513, 514, or 515 of host ss64.com: $ lsof -i @ss64.com:513-515. To list all files using any protocol on any port of mace.cc.purdue.edu (cc.purdue.edu is the default domain), use: $ lsof -i @mace. To list files using port 19421 like the Zoom video conferencing app, this returns the PID which you can. Using GeekTool and lsof, you can display an automatically updated list of open network connections directly on a Mac OS X desktop. This is tip is a “safe” alternative to the previously mentioned openports utility. On my system, to find which port is being used by a process with process id 9260, I run netstat -aon findstr 9260 As you can see in the above output, process 9260 is using port 8080.

Lsof is a program to 'list open files' and variants exist for major UNIX dialects such as macOS and Linux. Sudo: you need sudo privileges to determine which files are open by other users on your system (and ports are just open files in a large sense)-P: 'inhibits the conversion.

Mac List Ports Used By Process

When checking the listening ports on my Linux machine I put netstat some pants on:

Glory years. I want to see the ports and the programs listening on these ports. The netstat options used mean:

  • -p: show the program name / PID owning the socket
  • -a: show all connections
  • -n: show numerical addresses
  • -t: show only TCP connections

Somehow I’ve only noticed now that netstat on Mac OS X cannot show the program name. Actually on Mac OS X, the -p parameter of netstat doesn’t mean program or process but protocol. Also there is no -t parameter but it can be done using -ptcp.

There seems to be no way to get the same kind of info using netstat on Mac OS X. But everything is not lost. A tcp socket is just another type of file descriptor in Unix derivatives so we can use lsof to get the same info on Mac OS X:

This shows you the listening ports for programs running under your user name. If you want to see it for all users, you’ll have to use sudo.
