you need obvious full quake 4 with point release 1.4.2 to connect....
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

win32/linux drivers are in the gamex666.pk4, a serverconfig.cfg to spawn a dedicated server is in the q43a_txt.pk4 /docs, so after you connect and q43a mod has been downloaded, extract the serverconfig.cfg in quake4/q43a folder and do command :

for windows :
quake4Ded.exe +set fs_game q43a +exec serverconfig.cfg

for linux :
q4ded.x86 or quake4-dedicated +set fs_game q43a +exec serverconfig.cfg

edit serverconfig.cfg si_cvars tor the server game rules. etc etc

server running on unreleased beta, pure server working, connect and the mod will be downloaded and setup for you... yes, easy

and easy to start servers, all repacked so all you wont get "singleplayer only mod" error when starting servers etc, you will have win32/linux drivers for fully working SP/MP/dedicated server
