I am still a bit new to Flightgear, and still learning. I am having some problems getting connected to any of the multiplayer servers. I have tried multiple servers, but have been frequently trying mpserver05, as it seems more populated at the moment. Here are the steps I'm using, as referenced from the Multiplayer Guide (http://wiki.flightgear.org/Howto:_Multiplayer#Coping_with_abusive_behaviour):
I open up FGRun and select my aircraft and airport as normal. Then, on the config page, I check the box to enable AI Models also check the Multiplayer box. In the hostname field, I fill out mpserver05.flightgear.org and use port 5000 in the In and Out fields. Then, I simply run the game as I normally would.
I chose the San Francisco airport because it seems to be the most populated, and it would help me identify whether I'm connected and seeing other pilots or not. When I get into the game, I see no other aircraft, though the MP Map shows there are planes at the airport I'm at. Also, if I choose Multiplayer>Pilots, it says there are 0 pilots, and I also don't see my call sign showing up on the MP Map.
I think I've pretty much verified that I'm not getting connected, but can somebody help me try to identify what I'm doing wrong? I also tried addressing the host name as http://mpserver05.flightgear.org, with no luck. Additionally, for good practice, I forwarded port 5000 to the IP address of the machine I'm trying to make the connection from.
My specs are:
OS: Kubuntu 11.10 32-bit Linux operating system
Graphics: Nvidia 9600M GT
Flightgear version 2.4.0
Any help is much appreciated! Thanks in advance!
EDIT: I got a chance to try some more things. Disabling my router's firewall had no effect. Also, I noticed that in the menu Multiplayer>Multiplayer Settings, it reports that I am connected to the server. As mentioned above, I am on what appears to be an empty "server" though I tried connecting to several that MP Map shows people flying around in.
