Medal of Honor: Allied Assault Server Setup Guide

This guide walks you through setting up a Medal of Honor: Allied Assault server on an Ubuntu Server. Follow the steps carefully to ensure a smooth setup. The guide supports both the vanilla (v1.11) and Reborn (v1.12) patches.

Requirements

Ubuntu Server
Local IP of the server (e.g., 192.168.0.123)
Access to your router to forward ports (default: 12203)

Optional: Create a User for the Server

We will use the username gameservers for this guide. You can change it to any name, but ensure consistency throughout.

Create the user:

sudo adduser --home /home/gameservers gameservers

Grant sudo access (optional):

sudo usermod -aG sudo gameservers

Switch to the user:

su - gameservers

Setting Up the Files

Create a new directory:

mkdir mohaa

Navigate to the directory:

cd mohaa

Download the minimalist server files from github

git clone https://github.com/Grimm1/main

these are cut down versions of the original game files, they have had all images and sound files replace with placeholders.

Vanilla Server Setup

With the mohaa folder as your working directory, download the server files:

wget grimms3dworlds.ddns.net/ul/mohaa_lnxded.tar.gz

Extract the files:

tar -xvf mohaa_lnxded.tar.gz

Remove the tar file:

rm mohaa_lnxded.tar.gz

This should result in the following file structure:

fgameded.so
mohaa_lnxded
main/
    pak0.pk3
    pak1.pk3
    pak2.pk3
    pak3.pk3
    pak4.pk3
    pak5.pk3
    pak6.pk3
    pak7.pk3
    pak6EnUK.pk3

Reborn Server Setup

For a better experience, install the Reborn unofficial 1.12 patch from https://x-null.net/MOH2/. Follow the instructions there to apply the patch.

Common Setup for Vanilla and Reborn

Make the main executable file executable:

sudo chmod +x mohaa_lnxded

The MOHAA binaries are 32-bit, and modern Linux distributions may lack 32-bit support. Enable it with:

sudo dpkg --add-architecture i386

Update the package list:

sudo apt update

Install the required 32-bit dependencies:

sudo apt-get install libc6-i386 libstdc++5:i386

Test the server installation:

./mohaa_lnxded

Once verified, press Ctrl+C to stop the server.

Server Configuration

Create a configuration file (e.g., server.cfg) in the main folder. Open it in a text editor and paste the following configuration:

// Medal of Honor: Allied Assault Server Configuration File (Stock + Reborn 1.12 Patch)
// Place in the 'main' folder of your MOHAA server directory

Running the Server

Start the server with the following command:

./mohaa_lnxded +set dedicated 1 +set sv_maxclients 24 +set net_ip 192.168.0.123 +set net_port 12203 +set rconpassword mystrongpassword +exec server.cfg

Command Parameters:

sv_maxclients: Sets the maximum number of players.
net_ip: The local IP of the server (e.g., 192.168.0.123).
net_port: The port for the server (default: 12203; use different ports for multiple servers).
rconpassword: Sets the RCON password for remote administration.
+exec server.cfg: Specifies the configuration file to use.

Port Forwarding: Ensure port 12203 (or your chosen port) is forwarded on your router to the server’s local IP. You should also forward 12300. Other ports may be required.
IMPORTANT: The 12300 port is ALWAYS 12300 for the first server you run NO MATTER ITS PORT.
E.G. for 3 servers:

Server Port	Query port
12204	12300
12206	12301
12222	12302

Running as a Service

To run the server as a service in a tmux session, create the following systemd service files.

Master TMUX Service

Create /etc/systemd/system/master.service with:

[Unit]
Description=tmux master service
Wants=network-online.target
[Service]
Type=forking
User=gameservers
ExecStart=/usr/bin/tmux new-session -s master -d
ExecStop=/usr/bin/tmux kill-session -t master
[Install]
WantedBy=multi-user.target

MOHAA Server Service

Create /etc/systemd/system/mohserver.service with:

[Unit]
Description=TMUX MOHAA Server
PartOf=master.service
After=master.service
[Service]
Type=forking
User=gameservers
ExecStart=/usr/bin/tmux new-session -s mohserver -d 'cd /home/gameservers/mohaa && ./mohaa_lnxded +set dedicated 1 +set sv_maxclients 24 +set net_ip 192.168.0.123 +set net_port 12203 +exec server.cfg'
ExecStop=/usr/bin/tmux kill-session -t mohserver
Restart=always
RestartSec=5
WorkingDirectory=/home/gameservers/mohaa
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target

Enable and start the services:

sudo systemctl daemon-reload
sudo systemctl enable master.service
sudo systemctl enable mohserver.service
sudo systemctl start master.service
sudo systemctl start mohserver.service

Check the service status:

sudo systemctl status mohserver.service

Access the tmux session:

tmux attach-session -t mohserver

Note: The server will now run as a background service and automatically restart if it crashes. Use tmux to monitor or manage the session.
