Opening a port for iTunes and daapd
 

I'm running FC3, and trying to set up an iTunes server using mt-daapd. I installed it and it seems to be running. I can see and listen to my own music on ourTunes on my box, however when my roommates try and connect they get the following error:

"check that any firewall software running on either the shared computer or this computer has been set to allow communication on port 3689"

I just turned off my firewall completely and they can get my music. How can I just open port 3689 to the iTunes connections (i think its daap connections)? When I try to do it under the security level things under system settings it wont let trust 3689:daap as it doesn't recognize daap as a protocol

Many Thanks

maybe you could try just port 3689 and tcp or udp protovol...

OK, I've got it working using 3689:tcp. udp didn't work. But does this leave me vaulnerable at all? I don't really know much about networking.

You are using TCP/IP protocol every time you connect to the internet. The port opened shouldn't expose you to anything. However you could protect yourself by scanning your ports using "nmap localhost" command. This will reveal all the ports of your computer that are opened to the outer world. You can change the ports actions when they receive a packet from the internet using iptables (there are some tutorials on the net). The best thing to do, if you are connecting to a fixed IP is to allow only connections to and from that IP to your computers 3689 port :)

However doing this is all up to you.
