How to find which port TCP or UDP are being used by daemons on AIX OS.
For TCP protocol:
netstat -Aan |grep -E "\*.[0-9].+LISTEN" |awk '{print $1, substr($5,3)}' |while read socket port
do
echo "TCP Ports: " $port "--->" $(rmsock $socket tcpcb | grep held | awk -F'proccess|\\(|\\)' '{print "PID:", $2, "CMD:", $3}')
done
See an example:
(aix61):[root] /-> netstat -Aan |grep -E "\*.[0-9].+LISTEN" |awk '{print $1, substr($5,3)}' |while read socket port
> do
> echo "TCP Ports: " $port "--->" $(rmsock $socket tcpcb | grep held | awk -F'proccess|\\(|\\)' '{print "PID:", $2, "CMD:", $3}')
> done

For UDP protocol:
netstat -Aan |grep -E "udp.+\*.[0-9]" |awk '{print $1, substr($5,3)}' |while read socket port
do
echo "UDP Ports: " $port "--->" $(rmsock $socket inpcb | grep held | awk -F'proccess|\\(|\\)' '{print "PID:", $2, "CMD:", $3}')
done
See an example:
(aix61):[root] /-> netstat -Aan |grep -E "udp.+\*.[0-9]" |awk '{print $1, substr($5,3)}' |while read socket port
> do
> echo "UDP Ports: " $port "--->" $(rmsock $socket inpcb | grep held | awk -F'proccess|\\(|\\)' '{print "PID:", $2, "CMD:", $3}')
> done
