Hi,

Is there any command to know which application/program is listening
on a given socket.

For example, some daemons are running on the current system.
I want to know what application is listening on socket 1234.

Is this possible??

Thanks in advance.

Nestat displays all the ports...
I want a specific port.

Then pipe it through grep.

Hi,

Try the Open Source command 'lsof'. If you don't have it get it here:

http://freshmeat.net/projects/lsof/

If you are working on Solaris 5.8 > then 'pfiles' is a good choice, however
you will have to filter the output to get the info you need in this case.

Use netstat -ta | grep xxx

But I think that is different for different Unixes.

For Linux, that is netstat -anp | grep 1234
and you can just list your own processes or you have to be root.

There are some unixes without such a command.

Install and try lsof or fuser.

Guys,

I am familiar with piping and tried that earlier.
Netstat give some stream information
but not the actual process that is listening.

I dont know about others but in solaris it is giving out stream information
for example:

host:~ > netstat -a | grep 8001
3003c3ba8d8 stream-ord 300116d0e50 00000000 8001

So you see, I cant make out what the process is.

Anyway, thanks for the replies

I'm a newbie to linux so maybe I'm off the mark here, but I found the -p
returns the name of the program on that port.  It seems like you netstat
installed cause you're getting stuff back, what do the man pages say for
programs?

Man pages say,
-p    is used to "Show the net to media tables."

Thanks

Have you got lsof? If so this may show what program is using the socket
you mention, "lsof -n -i" may be what you need.
