To determine which ports are open, first Identify the services by using the

netstat command as follows:

ibmuser@lkasatcap1:/home/ibmuser>netstat -af inet

The last column of the netstat command output indicates the state of each

service. Services that are waiting for incoming connections are in the

LISTEN state.

ibmuser@lkasatcap1:/home/ibmuser>netstat -Aan | grep 6191

f1000e0000552bb0 tcp 0 0 *.6191 *.*

LISTEN

Get the PID

ibmuser@lkasatcap1:/home/ibmuser>rmsock f1000e0000552bb0 tcpcb

The socket 0x552808 is being held by proccess 3342730 (clcomd).

Get the actual process

ibmuser@lkasatcap1:/home/ibmuser>ps -ef | grep 3342730

root 3342730 1966366 0 Aug 07 - 0:26

/usr/es/sbin/cluster/clcomd -d

Get the Parent ID(PPID) of process

ibmuser@lkasatcap1:/home/ibmuser>ps -ef | grep 1966366

Another way is to use "lsof" command

Note:-lsof for AIX 6.1 resides on AIX Expansion Pack media.
