Trying to help someone out with something here.

They've got software which connects to server A on a specific port.
For some reason, its not working - they've tried telnet ip port and
that refuses to.

I've had a look and run netstat -ar | grep LIST and cant see the port
listed.

Surely this means that theres nothing on the server in question
listening on that port so its never going to work?

try netstat -a instead

Yes. Done that. Just a bit less.

you wrote its refusing, or is it timeout?
if its relly refusing you should see the port on the server.
which port is it?

Two very basic gotchas:

- You are telneting to a TCP (not UDP) server application, correct?

- Not all of them echo what you type, but telneting to a specific
port that is "alive" is definitely different from a "dead" port.

What is the *exact* error message you get?
