why would you want to restart this port?

 LISTEN  means that an application has opened this port and is actively "listening" on it for incoming connection requests.

This most normal behaviour and absolutely no reason to be worried!

If you want to have this port closed you must stop the application - there is definitely no other way!

To find out which application is listening you will need a tool like "lsof", which is on the AIX toolbox or, with AIX 6 or newer, on the expansion pack.

wmp, can you provide me some lsof command. I can run on my system and check the applications.

Do you run Siebel?

If so, stop the Siebel gateway NS server and the port will close.
Make sure to have set up the correct environment (this should be the case when logged in with the siebel administrator userid).

Afaik the command should be something like

but I'm not really sure because we don't have any Siebel server running anymore here at my company. It's all SAP now.

The command is:

lsof -i:2320

The first column will show the application, the second one will show the PID.

I think there is siebel running on the system,

 ps -ef | grep siebel
siebsupp 110958      1   0 11:51:21 pts/10  0:09 siebsvc -s gtwyns -a /f /siebel/gtwysrvr/sys/siebns.dat /t 2320 /c /siebel/gtwysrvr/bin/gateway.cfg

And now? If the gateway is running it's perfectly normal that it's listening on the specified port (which is the default port, by the way).
