If that does'nt help then theres an old BT Server I made years ago for Windows Which is the base model for the one above .
you can download it from here;
MASHYPE BT++ Server 429.8 MB compressed
also an old DM Server which was popular as well;
MASHYPE DM Server 298.5 MB compressed
for memory one of them or both need the Advertising
Code:
[IpServer.UdpServerQuery]
GameName=ut
MinNetVer=0
OldQueryPortNumber=0
bRestartServerOnPortSwap=False
bTeamInfo=False
[IpServer.UdpServerUplink]
DoUplink=True
UpdateMinutes=1
MasterServerAddress=
MasterServerPort=27900
Region=0
[IpDrv.HTTPDownload]
RedirectToURL=http://uz.ut-files.com/
ProxyServerHost=
ProxyServerPort=3128
UseCompression=True
Those are for windows systems although and to convert them to linux is a bit tricky but can be done.
Cheers.
ps: if you want to set them up for online use , then see my sig for the Server Crash Fixes , that should keep them up a bit longer.
pps: if you are usign XServerQuery then I don't think the Ipserver sections are needed.
