Setting up a server on Linux
This guide will help you setup and run a VU dedicated server on Linux using Wine. VU servers can also be ran on other platforms that Wine supports such as BSD and macOS, but this guide will focus specifically on a 64-bit Linux installation using the Ubuntu Server 18.04 distribution.
The first step is installing Wine. To do so, we'll simply follow the instructions for our operating system (in this case Ubuntu) found in this page.
We first enable support for 32-bit packages using the command below:
sudo dpkg --add-architecture i386
On Ubuntu 18.04, Wine requires some additional packages that are not in the main Ubuntu or Wine repositories. For that reason we'll use the openSUSE repositories to install it. First, we'll add the repository:
cd /tmp wget -nc https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/Debian_10/Release.key sudo apt-key add Release.key sudo apt-add-repository 'deb https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/xUbuntu_18.04/ ./'
See that you add the proper version for your version of distribution (ie. ubuntu 20.04 has a different url path for the repository)
Then, we'll update our local repository cache and install the stable version of Wine:
sudo apt update sudo apt install --install-recommends -y winehq-stable
If you want to later use ie. the liquorix kernel and fsync patches inside the latest wine-staging builds, install the winehq-staging package instead
sudo apt update sudo apt install --install-recommends -y winehq-staging
Setting up a 32-bit Wine prefix
In order to be able to run the VU server we'll need to create a 32-bit Wine prefix. In this guide, we'll assume you don't know what that means and that you haven't used Wine before or plan on using it for anything else, so we'll create it as the default user Wine prefix. If you know what a Wine prefix is, feel free to create it at a different location and use it when running the rest of the setup steps below.
To create the prefix simply run the following command as the user you created in the previous step:
WINEARCH=win32 wine wineboot
If you're running this on a headless environment (i.e. a server with no GUI) you will get a few errors and warnings. You can safely ignore them.
Getting Battlefield 3 and setting up the required folders
In order to be able to run the VU dedicated server you'll need the BF3 client files on your machine. The easiest way to get them would be to download the game via Origin on a Windows machine and then transfer them over to your Linux machine (using something like rsync or SCP). For the rest of this guide we'll assume that the BF3 files are located in the
~/bf3 folder (a folder named
bf3 inside your current user's home directory).
Next, we'll set up some folders for VU:
mkdir -p ~/vu/client mkdir -p ~/vu/instance
The first folder (
~/vu/client) is where we'll place the VU files. The second folder (
~/vu/instance) will be the server instance directory. This is a directory containing configuration files, mods, and other necessary files to run your server.
Installing required packages
Before we can set up VU we'll need to install a couple of extra package which will help us install some dependencies (namely the Visual C++ 2008 redistributable) and extract the VU package, as seen below:
sudo apt install -y xvfb unzip cd /tmp wget -nc https://download.microsoft.com/download/5/D/8/5D8C65CB-C849-4025-8E95-C3966CAFD8AE/vcredist_x86.exe xvfb-run wine /tmp/vcredist_x86.exe /q
You might see some errors or warnings when running the final command. You can safely ignore them.
You will also need to install the i386 version of ncurses if it is not already installed. You can do this as seen below:
sudo apt-get install libncurses5:i386 libncurses6:i386
Downloading and setting up VU
We must now download the VU files and extract them inside the
cd ~/vu/client wget https://veniceunleashed.net/files/vu.zip unzip vu.zip rm vu.zip
Then, we must transfer over the server key file we generated and downloaded previously, place it inside the
~/vu/instance directory, and name it
Activating the game
The final step before being able to run the VU server is to activate the game. This process requires an Origin account which owns BF3. Run the command below, replacing
<email> with your Origin account e-mail and
<password> with your account password:
wine ~/vu/client/vu.com -gamepath ~/bf3 -activate -o_mail <email> -o_pass <password>
You'll see a bunch of
fixme warnings printed in your terminal. You can safely ignore these. As soon as you see the
Your game has been successfully activated! message you're good to go!
Create a separate user to run VU as
Do not run VU as root. Instead create a user ie.
vu that will have the process running under it
addgroup --system vu adduser --system --home ~/bf3 --shell /bin/bash --ingroup vu --disabled-password vu
Running a VU server
You are now ready to run a VU server. To do so, use the command below:
wine ~/vu/client/vu.com -gamepath ~/bf3 -serverInstancePath "$(winepath -w ~/vu/instance)" -server -dedicated
Your server will start up and will soon be joinable by players. It is recommended to restart your server every now and then so you can receive updates and fixes.
Before users can join your server you'll need to make sure that specific ports are forwarded in your router (if you're behind NAT) and unblocked by your firewall. By default, a VU server will require the following ports to be open:
||UDP||Monitored Harmony, the VU networking layer.|
||UDP||Frostbite networking layer.|
||TCP||Remote administration protocol (RCON).|
Post-installation optional tasks
You will likely also want to run VU as a service so here is an example of a unit file for VU:
[Unit] Description=Venice Unleashed After=network.target [Service] #Environment=WINEESYNC=1 #Environment=WINEFSYNC=1 #Environment=WINEDEBUG=+esync #Environment=WINEDEBUG=+fsync CPUSchedulingPolicy=fifo CPUSchedulingPriority=20 Type=forking User=vu Group=vu ExecStart=/usr/bin/screen -dmS vu /usr/bin/wine ~/vu/client/vu.com -gamepath ~/bf3 -serverInstancePath "$(winepath -w ~/vu/instance)" -server -dedicated ExecStop=/usr/bin/screen -XS vu quit ExecStop=/usr/bin/wineserver -k Restart=always RestartSec=20 [Install] WantedBy=multi-user.target
To explain the options a bit, the
CPUSchedulingPriority are better suited for realtime processes like gameservers. Uncomment the
WINEFSYNC option if you are using an fsync patched kernel like liquorix or similar.
The paths in the ExecStart clause need to be adjusted for your specific environment. The Z: drive is the default linux filesystem mapped drive letter for wine (there is a known issue with providing just the regular unix path for this.)
Running VU on dedicated hardware is highly recommended, however if you are determined to run it inside a virtual machine on a host you control (a third party shared VPS will not work here), you must tweak the virtualization host side cpu scheduler priorities as well, otherwise load on the same core that the core 0 ends up binding to can cause strange issues (ie. another virtual machine is contending for clock cycles on the same core with the VU servers first core).
