port number -> PID

[bandez]

Hello,

How can I know to which port belongs to which process?
E.g :
netstat -a said:
udp4 0 0 *.54263 *.*
Which process listen on 54263?

Thanks !!

lsof -i 54263

Hi bandez

Here is a small script to find any port(listening) versus process

#!/bin/ksh
#script title=/tmp/port-process.ksh
netstat -a|grep LISTEN|awk {print $4}>/tmp/port.list
for PORT in `cat /tmp/port.list`
do
/usr/sbin/lsof -i | grep $PORT
done
echo "script exection $0 completed"

Hi bandez

Here is a small script to find any port(listening) versus process

#!/bin/ksh
#script title=/tmp/port-process.ksh
netstat -a|grep LISTEN|awk '{print $4}'>/tmp/port.list
for PORT in `cat /tmp/port.list`
do
/usr/sbin/lsof -i | grep $PORT
done
echo "script exection $0 completed"

This is tested and works fine..No probs!
