Find Out What is Running on a Particular Port
Ever wondered what is tying up one of your ports when you try to spin something up and get the “already a process listening on port 182” error message?
Well enter netstat, which is handy utility for finding out what ports are taken.
The basic command is:
netstat
This will crawl your ports and give you a list of ports that are taken.
Proto Local Address Foreign Address State TCP 127.0.0.1:1282 MACHINE:1283 ESTABLISHED TCP 127.0.0.1:1283 MACHINE:1282 ESTABLISHED
This isn’t enough, so you’ll probably want details of the app that is causing the port to be taken. So you can use:
netstat -b
If you get the message “The requested operation requires elevation”, either hold your computer above your head, or run command prompt in Administrator mode.
