Showing network connections

[Ferdie Castro]

Hi I am having problems showing network connections of users connecting to my server and what port are they using. Apparently these are corba applications and I have Orbix IONA application in my server as well. Is there a command that shows details of connections in my Orbix application server using HP-UX 11.0. Appreciate your feedback guys. thanks.

Hi,

Start with

$ netstat -a

[Ferdie Castro]

Thanks I saw the results but would it be possible to see what these sessions are doing?

[Steven E. Protter]

To identify what the session is doing you'll need to assoicate the netstat output with a process id.

Then you can use tusc to see more detail than you ever imagined.

If you only more network information, you might try netstat -an

A lot can be learned from just netstat -a

Certain ports are used for certain activities as shown in /etc/services.

What kind of activity are you trying to trace?

To get some further information, you could look at using 'lsof'. You could also go to the extremes of doing some network tracing. See this posting, which has some useful tips.

Hi, thanks for feedback. I'm trying to trace corba client servers and what they are executing.

If you want to see what they're doing then you need a sniffer like etheral or tcpdump. Here's tcpdump:

#netstat -a | grep -i orbix

you can use nettl to trace.
