Command for open ports!

[Mike_21]

I know you can loof in /etc/services, but is there a command that will list what ports are open, and listening?

Thanks

You can do a netstat -na|grep LISTEN to find all the ports that are currently being used. But you'd have to get lsof to find out what program is using those ports...see the other recent thread for more details:

A couple of ways to do what you want I think.

First, have a look at the netstat command.

Second, install lsof.

Perhaps you are looking for the command:

netstat -a

If this is not what you need let us know.

netstat -an | grep LISTEN

Hi,

Install lsof. You can get it from any of HP-UX porting centere website ;

Do you know if there is a diagnostic I could use to determine if another process is trying to use port xxxx?

[Lou Zirko_1]

You can do

netstat -a | grep

or as others have suggested get and install lsof and use the the options that they spelled out for you.
