How to see which programs are opening ports

Filed under: Computer Security,Security Tools — Suramya @ 4:02 AM

These tools will help you identify which programs are opening what ports on the system.

1. lsof | grep ‘IPv.’

lsof shows the list of open files, piping it through grep and searching for IPv will give you a list of ports used by a program

lsof -i TCP:<PORT>

where PORT is the one you need to know about the program behind it.

2. netstat -anp

Should display open ports, machines connected to the ports as well as which application has that port open.

If you know of any other ways let me know.
