info : http://www.moddb.com/mods/q43a/downloads/q43a-1115-win32linux

just connect and it will all be downloaded [ delete any other q43a folder first ] :
connect : 85.234.148.170:27960
and will download the cmp mappack.pk4 with the addon.conf deleted out ot it, it causes conflict and a "data out of sync" error message, all the map def info is in the maps.def instead of the addon.conf

http://www.quakeservers.net/quake4/server_status/5145/

win32/linux drivers are in the gamex666.pk4, a serverconfig.cfg to spawn a dedicated server is in the q43a_txt.pk4 /docs

quake4ded.exe +set fs_game q43a +exec serverconfig.cfg

nothing else is needed to be done, and on linux q4-ded or whatever
