How to enable a port on Mandrake??
 

I have a Mandrake 9.1 box and can see port 80, but not port 8080.

Is there a file somewhere that determines which ports are enabled / disabled?

There is a bog standard JBOSS/Jetty installation on the box so I know there is something behind port 8080.

Many thanks for any help anyone is able to give some help, I need to get this working.

It depends on the services really that are running and what port they use by default. AFAIK, nothing uses 8080 by default. I do know however alot use that port to run proxy servers on, etc.

Thanks,
Is there any easy way to determine what services are actually running?

I've disabled the apache web server so I know that is not grabbing the port.

Easiest way is to use top or ps -aux to see what you have running. If you want graphical there is a gtop you can run to watch your running processes, etc.

more /etc/services ,you can modify it.
netsta- nat
It will display opened ports of your box.
