How do I find ports in use

[mikejordan]

I have a solaris 8 box running oracle, and I need to install some new software that needs a unique port. Does anyone know how I can get a list of all the ports numbers that are in use, or reserved?
Thanks, Mike

hi,

/etc/services has all registered ports and what they are used for;
netstat -a shows whats in use.

hope this helps,

Thanks, that's what I needed. /etc/services seems to be the ports set up by solaris, but netstat gives me details of oracle server ports and more. Thanks for your help.
