How can I tell what process is using a particular port?

Karen Elrod — Tue, 08 Aug 2000 18:02:06 GMT

HPUX 10.20
Netstat -a lists active port, how can I tell what process is tied to it.
I have a port that is tied up by something using a wrong port number. I have used netstat to see that it is active:
tcp 0 0 dixie.50680 *.* LISTEN
Thanks
Karen

There's a shareware product called lsof I've used to do this before.

The command netstat -an will give you a little more of what your looking for....BUT you will find that getting and using lsof is more preferred.
Here's where you can find it:
LSOF can be dowloaded using the following procedure:

1. Go to www.software.hp.com
2. Scroll down to the end and follow the link "HPUX Public Domain Software"
3. Type lsof into the search field and click search.
4. Download the current version of lsof

you can also get it from the original source the advantage is that you can get the latest version and compile it to suit you.
