Hi everyone.
I searched the forum and I didn't find a complete howto abo setting up q3a server on linux, so I thought I'll make one myself... hope someone finds it useful...

1. What Do We Need

- PC with hardware matching minimum q3a requirements
- Linux distro with working x-windows
- File pak0.pk3 from Q3A CD, Linux q3a installer, excessiveplus mod
- minimal knowledge about working in Linux console

2. How Do We Do It

First we need to make directory for our q3a server, for example in our home directory:

$ mkdir ~/q3a/baseq3/

Then we need to copy pak0.pk3 into the baseq3 directory. Assuming that file is on CD, we need to mount it first:

$ su
[we'll be asked for root password]
# mount /dev/cdrom

(Hint: if you don't know what's the name of your cd-rom device, check out /etc/fstab)

Then we copy pak0.pk3 into our fresh q3a directory:

$ cp /mnt/cdrom/quake/baseq3/pak0.pk3 ~/q3a/baseq3/

Now it's time to install 'linuxq3apoint-1.32b.x86.run'. Before that, we have to make sure we're running X. Assuming that q3a *.run setup file is in our home directory:

$ cd ~
$ sh linuxq3apoint-1.32b.x86.run

The installation window should appear on the screen. We should now accept the license and choose installation options. As a place to install q3a in, we select created q3a dir in our home directory (~/q3a/). We can install symlinks wherever we want to (remember that you won't be allowed to place symlinks in /usr/local/bin or sth if you run installer as a plain user). We select not to install Team Arena, but to install Punkbuster.

When the installation is complete, we should now update punkbuster (if we want to use it). We have to download file 'pbsetup.run' into ~/q3a/ dir and launch it. It's really easy to use; we have to select game type and type its location. Program will do the rest - download and install updates.

The only thing before setting up our server is to install excessiveplus on it. So, we now have to download excessiveplus (zip version) and unpack it into q3a dir, that there will be an 'excessiveplus' subdirectory in ~/q3a/.

$ cd ~/q3a/
$ unzip xp-1.03-full.zip

The last step is starting our server. To do that, we move into our q3a dir and type:

$ ./quake3 +set dedicated 1 +set fs_game excessiveplus +exec [our_config_file.cfg]

(See Q3A manual for addidional commands)

The server is up and running. We can launch it without starting X-window, but base x11 package has to be installed in the system.

I will try to correct every oversight somebody will note.

It would be good if someone sticks that topic to the top.
