THIS GUIDE WILL COVER THE INSTALLATION AND OPERATION OF A CALL OF DUTY 4 (COD4)

Requirements
Call of Duty 4 game client installer CD or image.
Debian server running a stable release (Wheezy, Jessie)
Xen/KVM VPS (1 CPU, 1GB Memory, 20GB Storage) as a minimum. This configuration may not be suitable for large servers.

Installation

Login as root on the server that you will be using for this installation.

Run the command below to update your server’s list of available packages from the repositories and then upgrade any existing packages.

apt-get update && apt-get upgrade

Screen is often times included with the OS image by default, but you may be required to install it yourself.

apt-get install screen

Because the Call of Duty 4 server only runs on i386 machines, you have to enable the “multilib” feature in Debian.

dpkg --add-architecture i386
apt-get update

For security purposes, we do not want to run the server using the root account. You should use a standard user account.

Create a directory for the game server.

cd ~
mkdir cod4

Download the Call of Duty 4 dedicated server.

cd cod4
wget http://treefort.icculus.org/cod/cod4-linux-server-06282008.tar.bz2

The download size is roughly 280 MB. When the download finishes, unpack the package.

tar -xvjf cod4-linux-server-06282008.tar.bz2

Install the COD4 game client onto your computer. Copy the main and zone folder of the game client onto the COD4 directory of your server using your favorite SCP client.

Once your upload completes, download the IceOps made executable. It contains various bugfixes and improvements.

wget https://iceops.in/cod4x17a_dedrun

Make the server “executable”.

chmod +x cod4x17a_dedrun

Create a config file for the dedicated server.

nano general.cfg

If you want to run a simple “Team Deathmatch” or “Search & Destroy” server, then use this sample config.

Save your changes to the config file.

Next, create a start-up script that starts a dedicated server (with screen) and enables map rotation.

nano cod4.sh

Paste the following content into the script file.

#!/bin/bash
screen -dmS cod4 ./cod4x17a_dedrun +set sv_authorizemode "-1" +exex general.cfg +map_rotate

Save your changes to the script file, then make it “executable”.

chmod +x cod4.sh

If you are using the iptables firewall, add the following rules. Update the ports if you have changed them in the server configuration file.

-A INPUT -p udp --dport 28960 -j ACCEPT
-A INPUT -p udp --sport 28960 -j ACCEPT
-A INPUT -p tcp --dport 28960 -j ACCEPT
-A INPUT -p tcp --sport 28960 -j ACCEPT
-A INPUT -p udp --dport 20800 -j ACCEPT
-A INPUT -p udp --sport 20800 -j ACCEPT
-A INPUT -p tcp --dport 20800 -j ACCEPT
-A INPUT -p tcp --sport 20800 -j ACCEPT
-A INPUT -p udp --dport 20810 -j ACCEPT
-A INPUT -p udp --sport 20810 -j ACCEPT
-A INPUT -p tcp --dport 20810 -j ACCEPT
-A INPUT -p tcp --sport 20810 -j ACCEPT

Finally, start your server.

./cod4.sh
