GWIA not responding on port 25

Question

Hello
we just installed GroupWise 7.0.1 Beta on OES Linux SP2. The problem we do
have is that GWIA can't be contacted on port 25, even local telnet
(i.e. "telnet ip 25" says "connection refused") won't work.
So we changed the GWA SMTP-Listening port to something else (5025) and
activated port translation on our router from port 25 to port 5025 and we
managed to get the whole thing up.
But we feel that this can't be the final solution, so:
why does GWIA not respond on port 25? (we searched in the runlevel Editor
of Yast for any services that might run on port 25 (i.e. sendmail) but
didn't find any).
is there a linux command which shows what services are listening on what
ports? (i am mostly netware-expert, not linux that's why i'm asking).
Thanks for any help
Andrej

Answer 1

Disregard the previous post. I neglected to read through the entire
message. The only other thought that I have is that there is a firewall
setup that can be enabled on the OES box in YAST that might be interfering.
I am not sitting in front of a OES box, otherwise I'd point the direction to
find it. I believe it is in the Network settings.
Sorry about the previous post.
