This is a script for solaris. Give it the port number you want to check, and it will tell you what process is listening on that port. It’s not as good as lsof, but it’ll get you this info if you need it and lsof isn’t available.

#!/bin/ksh
#This will tell you what processes are listening
#to or using a particular port. For Solaris
#Must be run as root
