A licensed copy of Quake 4 retail for Windows(r) is required. You will copy the assets files from it and use the CD key. PLEASE NOTE: The Linux version of Quake 4 is NOT supported by Activision Customer Support. The following files must be copied from the install CDs  to your q4base/ directory ( md5 sums provided as reference ): If you copy them before running the installer you will need to create the paths, by default /usr/local/games/quake4/q4base If you copy after running the installer, make sure not to replace any paks the installer might have provided. a9f6a2e4bf8e193591954f75d1d39f85 game000.pk4 b201b914167f47061fa5f975af527122 pak001.pk4 dabe2c88e004198947431250e3f4ca1d pak002.pk4 8573f05af4c9568880cc464d06292079 pak003.pk4 12ff4006a7f7181ac16835d05c59905f pak004.pk4 3576213f4e00f06baf3cd5de089a538a pak005.pk4 aec7bb418b9a86256f9e5daee894dee2 pak006.pk4 0f53b4fb4df2c14fcd10012baf8b2f87 pak007.pk4 b099d75869f0ffcbcb8e5166374af345 pak008.pk4 cb2b44bf573559dc19b488d9e1e5bec3 pak009.pk4 d024073349dc917b4feab49e6abc417b pak010.pk4 98c854d94ce1da5272952b77821823df pak011.pk4 e77a2fda6656495d38773e05bbffda33 pak012.pk4 669d6d9a30b798d19434972475b98c53 zpak_english.pk4 2cabddd692e214c78c20a464da43f1ef zpak_french.pk4 4ee7eb637cde6bcfe3a9ffac5e4579dd zpak_italian.pk4 36eee38e6c2dce12986f7192a5a996e5 zpak_spanish.pk4 Note: the Linux installer will reinstall the game*.pk4. Note: the German version of the game uses a completely different set of assets. See the FAQ entry below for details. Start the game with the command: quake4 Start the dedicated server with the command: quake4-dedicated  - note that if you have the DVD release, all the files are in the same directory. Otherwise they are spread out on each CDs. For the DVD edition, the files are in Setup/Data/q4base

In particular, you can read some elements of server adminstration on the Quake 4 modding site.

German release of Quake 4
The checksums of the pak files to be copied for the German version of Quake 4 are below. Note that it will only work in multiplayer with other german copies of the game.
The installation instructions are otherwise the same.

Crashes on startup when loading the game module
Only applies to releases 1.0.x of Quake 4. Bug is fixed 1.1 upwards
Some Debian and Debian-based distributions ( like Ubuntu ) are crashing during startup. It appears this is caused by the SDL packages selection. You need to install libsdl1.2debian-alsa or libsdl1.2debian-oss instead of libsdl1.2debian-all.
FYI, it is not clear what happens with this crash. Happens during initialization of static variables, has to do with a cvar named g_log and goes away if renamed to something else. So it would look like this version of SDL has g_log already defined from somewhere else and the dynamic loader getting confused over it.
How do I toggle the console?
Use Ctrl+Alt+~ to toggle the console. If you set com_allowConsole to 1, you can use ~ only ( also note that shift-~ gives you a smaller console ).
Some tips on map cycling
You can use si_mapCycle to set a list of maps to play through. Something like "mp/q4dm11v1;mp/q4dm3;mp/q4dm6;mp/q4dm7;mp/q4dm8;mp/q4ctf5" for instance ( that's the Tourney maps ). si_tourneyLimit counts how many tournaments will run before going to the next map ( other game types always switch ).
You can also use g_mapCycle and execute a script for each map rotation. Powerful but a bit more involved. Look at the one we provide to get an idea how you can customize it.
The game comes with some ready made .cfg files for the various gametypes and maps. e.g. you can type exec dm.cfg at the console to start a deathmatch server with the default configuration settings.
If you want to require a password to join your server, set the value of g_password to the password. Then actually enable/disable it with si_usePass. Don't set the password in si_usePass, that won't work.
Some information for firewall configurations to play nice with quake4:
all game traffic is UDP
by default servers listen on port 28004 ( if you run several servers on the same machines, it will use 28004, 28005 etc. )
your server needs to be able to talk to the master server at q4master.idsoftware.com on port 27950
Cannot connect a Linux client to a Windows 1.0 pure server
Only applies to release 1.0.x of Quake 4.
This is because the Windows version was released first and didn't come with a game code pak for Linux. There is a simple fix, server admins need to put the Linux gamecode pak file game100.pk4 into the q4base/ directory:
NOTE: That this only applies to version 1.0 ( gold ) and the updates compatible with it ( all the 1.0.x versions ). Make sure that file is named game100.pk4, looks like some web browsers or proxies like to rename it to game100.zip.
NOTE: The Linux demo has the same issue and cannot be fixed. Windows clients can connect to a Linux server, but Linux clients will only see and connect to Linux servers.
File permissions on install CDs
The install CDs have Rock Ridge extensions which may get in the way of copying the files to your hard drive. You should make sure to mount the CDs ignoring the extension ( "-o norock" ) or setup appropriate mounted partition ownership / copy files as root and fixup manually.
AntiAliasing/MultiSampling / Windows are opaque
Multisampling can be enabled through the engine by setting r_multiSamples to an appropriate value ( Quake4 1.3 ). If you enable multisampling through GPU specific interfaces like nvcontrol, make sure you set r_multiSamples to match. If you get opaque transparent surfaces after enabling it, make sure r_alphaToCoverage is set to 1.
If you are getting opaque grey windows, and are not using multisampling, make sure r_multiSamples is set to 0
internal server browser in 18.104.22.168 / build 2147 will only show 1000 servers max. Third party browsers like xqf can retrieve and filter the complete list.
- if you have a non US keyboard, you may not be able to get to the console. Use an applet in gnome or kde to switch to a qwerty layout before playing, or use xmodmap to remap the console key you want to emit keycode 49.
the game is crashing when loading the game dynamic modules on some Debian and derivates distros. See the workaround
- you can't use savegames across different operating systems. Games you save on Windows(r) are likely to crash if you load them up on GNU/Linux.
If you want to report an issue with the game, you should make sure that your report includes all information useful to characterize and reproduce the problem.
check the Linux Gamers' FAQ for any issue not covered here
search on Google
include the computer's hardware and software description ( CPU, RAM, 3D Card, distribution, kernel etc. )
include the output of glxinfo
if appropriate, send a console log, a link to a save game, a screenshot, an strace ..
Note that we can't help you with OS-specific issues like configuring OpenGL correctly, configuring ALSA or configuring the network.
If you are sending a console log, make sure to enable developer output:
$ quake4 +set developer 1 +set logfile 1
( the log is written to ~/.quake4/q4base or ~/.quake4/yourmod ) Do not cut the log to the part you think is relevant. We often want to see the initialization of the renderer and filesystem.
As a rule of thumb, a bug is unlikely to be investigated unless it has been reported by different people or on different systems.
