Remote Access Service

Hi.

We have some remote access software running on a Cent OS server. The service is called SimpleHelp if anyone is familiar. We recently migrated from a VPS to a dedicated server and have since been having problems.

The program uses port 900 which has been opened for both TCP and UDP. Clients using a http/tcp connection seem to be working. Those using UDP will show as online but cannot connect (90% use UDP only...).

I used nmap to scan port 900 UDP on the server. It shows as open but the listening service is named: omginitialrefs
This service is not related to our remote access software and I have no idea what it does. Can it safely be stopped and how?

Thanks in advance for any replies

Just thought I should add... changing to a different port would be a major difficulty as we would have to manually update every client to look at the new port.

Another thought - If I were to change the remote software to listen on say port 5432 could all traffic destined for port 900 be redirected to port 5432?

I'm aware of netstat I just didn't realise it worked on Linux.

Anyway, the problem is now solved. The missing PC's have came on-line throughout the day and we haven't had any issues since I made the changes described previously.

Adding you as a partial solution as your explanation of the nmap output cleared things up for me.

The firewall redirect of port 900 is what resolved all our problems.
