Hey there,
I am new to this forum and also very new to linux. I run a web radio station and recently had to acquire my own server. Since my administrator is no longer with us I have decided to take on the task of getting things set up. The problem i am having is i need to have a couple of ports opened up and not sure how to do this. is there a general way to open up ports? My server is running Fedora linux version 3. Please help. Thank you.

A port is opened when some application is listening on it. That's all there is to it, unless you have a firewall (and you probably should). The Linux firewall program is called iptables, which is a front-end for the netfilter stuff in the kernel. You can learn iptables syntax, and it's actually not that hard -- you can Google for iptables tutorials, however, if you want to get started fast there are a number of GUI front-ends such as guarddog and firestarter. If you are running Fedora, typing system-config-firewall at a terminal as root should bring up a little graphical tool to manage the firewall.
