Need help with simple problem....I hope
 

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.

Typically the process is something like this:
- Start the application.
- If the app uses libwrap, make entries to hosts.allow and hosts.deny as needed.
- Modify and reload iptables ruleset as needed.
- Allow access at any perimeter firewall.

My read of the original post tells me that he will not understand this.....

how do you do the things you mention---or where would one look for info?
how do your suggestions relate to "opening a port"

Yes, the process that I posted was "in general", but I would think that each step contains enough keywords for him to search on. With a few quick Google searches and reading the man pages, he should be able to accomplish each step. There are many places that a port can be opened, and without specifics on the application and where connectivity is failing, it would be difficult to determine where the port is still closed.

Thank you very guys and the both of you were actually right. I did some investigation based on the response i got from you guys and was actually able to figure out the problem. We started the application and even though it was listening on a particular port, the port was still closed only to find out that it's being deliberately blocked by the ISP. Using another port solve the problem. Thanks again guys.
