Port not listening
 

I created a service in xinetd and assigned a port. I added xinetd to chkconfig and set the run levels. The service shows as "on" in chkconfig --list. I opened the ports in the firewall. netstat -an does not show the port listening and I cannot connect to the port. I am using Red Hat Enterprise. What else could be keeping that port from listening?

The service isn't running. You don't say what service you're trying to run, or what version of RHEL either. If the service is up and running, the port will be listening. Otherwise, it won't. Running netstat -an will show it, regardless of how the firewall is configured.

Have you checked the log(s) for the service you're trying to run?

I found the problem. In the service I created I needed a space in the line "server = xxx" I had "server= xxx".
