Solaris - Find a process using a specific port

One of the DBAs found/knocked up a useful script which searches for what process is using the entered port number.

Background:

From a NETSTAT the DBAs found that a unknown process was hogging a port number that another application they were installing wanted to use.

Netstat syntax:

# netstat -a | grep <port-number>

Process finding script:

#!/bin/bash

# Get the process which listens on port

# $1 is the port we are looking for

if [ $# -lt 1 ]

then

echo "Please provide a port number parameter for this script"

echo "e.g. $0 22"

exit

fi

echo "Greping for your port, please be patient (CTRL+Z breaks) ... "

for i in `ls /proc`

do

pfiles $i | grep AF_INET | grep $1

if [ $? -eq 0 ]

then

echo Is owned by pid $i

fi

done
