SUMMARY: How to determine what app/program is using a spcific TCP or UDP p ort.

Thanks to Casper Dik, Vince Merrell, Neil Quiogue and David Flores

pfiles is the way to go.

Now if you want to know what port a process is using, just go with

pfiles <PID> | grep port.

If what you want (as I did) is to find out what process is using a specific
port (i.e. 8003),
all I could come up with is this:

for i in `ps -ef | awk '{print $2}'`
do
    if (pfiles $i | grep 8003); then
        echo "Process $i is using port $1"
    fi
done

If you know/can think of/find anything smarter or less ugly than the above,
please feel free to send it to me ;-)

Cheers

Hello Folks, 

Is there a way with the native Solaris 9 commands (i.e. NOT lsof) to
determine what application/program is using a specific TCP or UDP port(s).

TIA
