[CoD4] Setup CoD4(x) on your ubuntu 14.04 server

First off, I'd like to thank any and all sources I've used over the years to gather all this information. I cannot name them individually, however, if you feel special enough that you think you require a listing, send me a PM and I'll put you in my list of special people.


So, first off, you'd need a server with ubuntu 14.04 x64 minimal. Any other linux installation might also work (debian is closesly related to ubuntu, so the steps listed here will probably work on a debian install as well) (CentOS is not that closely related so most steps will require changing). Aquiring such a server is a thing you have to figure out for yourself. You can buy one of the many VPS's (virtual private servers) or run linux locally (on your own server/inside a VM/on your main pc) and go from there.


Step 1: Securing your server

The first steps you should always take when running any internet-facing server is securing the server. The most common attack vector for internet facing servers is ssh root password bruteforcing (clicky), so moving away from both password usage for ssh logon as well as root login is a valid first step. Basically, it involves you following this guide: guide is here. If you're really paranoid about security you might want to generate your public/private key file on your local pc instead of on your server, use puttygen.

The next step in securing your ssh login is putting it on a different port. By default ssh listens on port 22, on ANY ssh installation. This means that portscans/brute force attacks will try port 22 first. Changing your ssh port basically boils down to editting /etc/ssh/sshd_config and changing the Port 22 line to some other port, preferably above 1024, but it must be below 65536 (I'm using a port between 30000 and 40000). Hereafter you have to restart your ssh deamon (ubuntu: service ssh restart) and reconnect your client on the new port.

After this, you should configure a firewall (example here). Keep in mind that changing your ssh port requires you to actually read the stuff at that link or you might lock yourself out of your server.

Step 2: Installing CoD4x prerequisites
CoD4x prerequisites are as easy as doing:

Code:

---

dpkg --add-architecture i386
apt-get update
apt-get install build-essential nasm bc git libstdc++6:i386 g++-multilib

---

Step 3: Installing CoD4
Installing cod4 is as simple as uploading the iwd files from an existing cod4 install main directory and the .ff files from the zone/english directory to, for example, /home/USERNAME/_stock/cod4/main/ and /home/USERNAME/_stock/cod4/zone/english
These files need to be readable by the useraccount that will start the server.

Furthermore, you'll need the stock cod4_lnxded file, which in the case of cod4x is read from a .iwd file in your main directory. So, upload this file: Attachment 1327 to your main dir before proceeding.

Step 4: Compiling CoD4x
First off, clone this git repo:

Code:

---

git clone https://github.com/Zinglish/CoD4X17a-WonderlandX

---

If the git ever goes offline, use this: Attachment 1328

Then, edit a file to fix default jump_slowdownenabled behaviour:

Code:

---

Open Cod$X17a-WonderlandX/src/g_sv_movement.c, go to line 189 and change

if(ps->var_03 & 64 && ps->pm_time <= 1800 ){

to

if(ps->pm_flags & 0x4000 && ps->pm_time <= 1800 ){

---

Now, compile CoD4x with

Code:

---

./build_cod4x17a_elf.sh

---

Step 5: Starting your CoD4x server
Create a .sh file with the following contents:

Code:

---

#!/bin/bash

sv_maxclients="32"
fs_game="mods/your_mod_folder_here"
fs_homepath="/home/USER_HERE/YOUR_COD_DIR"
cod="/full/path/to/CoD4X17a-WonderlandX/bin/cod4x17a_dedrun"
com_hunkMegs="256"
config="configfile.cfg"
authorizemode="0" #0=cracked, 1=original
net_port="28960"


args=\
"+set fs_homepath \"$fs_homepath\" "\
"+set fs_game $fs_game "\
"+set net_port $net_port "\
"+set com_hunkMegs $com_hunkMegs "\
"+set sv_maxclients $sv_maxclients "\
"+set fs_basepath \"$fs_homepath\" "\
"+set sv_authorizemode $authorizemode "\
"+exec $config"

$cod $args +set g_gametype war +map mp_crash

---

Adjust where required.
