Server files for running a Longvinter server.

If you have any trouble following the guide. Please send us a message in Discord we are more than happy to help you out!

This guide is made with Ubuntu 20.04

Requirements and prerequisites

• GIT installed in your system
• GIT LFS installed in your system
• SteamCMD installed in your system
• Broadband internet connection
• Router with the ability to port forward
• Min. 2 GB RAM

Installing GIT Large file system

.pak files are large and we need to install Git Lfs in order to download them

Run the following commands according to your chosen system:

Ubuntu/Debian

• $ apt update
• $ apt install git git-lfs

Arch-Linux

• $ pacman -Sy
• $ pacman -S git git-lfs

Fedora

• $ yum update
• $ yum install git git-lfs

Creating a dedicated user

• $ useradd -m -d /home/steam steamcmd
• $ passwd steamcmd (Choose a stronge secure password)
• $ usermod -aG sudo steamcmd
• $ su steamcmd

Installing Steam SDK

The Steam server browser needs steamsdk and for this we need to install SteamCMD, we will do this under the steamcmd user.

• cd ~/ Makes sure we are in the home directory
• mkdir steamcmd Makes SteamCMD directory
• cd steamcmd Goes to the SteamCMD directory
• apt install lib32stdc++6 Install lib32std
• wget https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz Downloads SteamCMD Tar File.
• tar -xvzf steamcmd_linux.tar.gz Extracts SteamCMD
• ./steamcmd.sh +force_install_dir . +login anonymous +app_update 1007 +quit Runs SteamCMD to login, install a app update and quit upon completion.

Steam CMD will install updates automatically and login to install 64-bit SDK.

Copying SDK to right place

We still need to move the sdk to default location where the server tries to

• cd ~/.steam Go to the steam folder
• mkdir sdk64 Create folder for the sdk
• cp ~/steamcmd/linux64/steamclient.so ~/.steam/sdk64/ Copy the steamclient.so from SteamCmd to .steam/sdk64 folder

Installing the server.

After this we want to make sure we are in home directory

• cd ~/

Then we can clone the Linux repository

• git clone https://github.com/Uuvana-Studios/longvinter-linux-server.git

Then we want to give permission for this folder to execute commands with

• sudo chmod -R ugo+rwx longvinter-linux-server/

After this we can open the required ports by executing the following commands:

• sudo iptables -I INPUT -p udp --dport 7777 -j ACCEPT
• sudo iptables -I INPUT -p tcp --dport 7777 --syn -j ACCEPT
• sudo iptables -I INPUT -p udp --dport 27016 -j ACCEPT
• sudo iptables -I INPUT -p tcp --dport 27016 --syn -j ACCEPT
• sudo iptables -I INPUT -p udp --dport 27015 -j ACCEPT
• sudo iptables -I INPUT -p tcp --dport 27015 --syn -j ACCEPT

Customize the server

Server values can be customized with Game.ini

Create the file for edit with nano ~/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini

Add the following content there

[/Game/Blueprints/Server/GI_AdvancedSessions.GI_AdvancedSessions_C]
ServerName=Unnamed Island
MaxPlayers=32
ServerMOTD=Welcome to Longvinter Island!
Password=
CommunityWebsite=www.longvinter.com

[/Game/Blueprints/Server/GM_Longvinter.GM_Longvinter_C]
AdminSteamID=76561198965966997

• ServerName: Name that shows up in the server browser. Please don't call your server with OFFICIAL name. We want players to clearly know if they are joining a server that is hosted by other players.
• ServerMOTD: Server message that is on a signs around the island.
• MaxPlayer: Maximum allowed players that can connect at any given time.
• CommunityWebsite: Allows you to promote a website on a same place where the server message is shown. This link can be opened in-game.
• Password: Add you password here. Use only number and letters. If left empty there is no password on the server.
• AdminSteamID: Here you can add all the admins that you want to have in the server. If you want to add multiple separate id's with single space.
  • AdminSteamID=76561198965966997 11859676569976596

Run the server

Start the server manually with shell script

• sh /home/steam/longvinter-linux-server/LongvinterServer.sh

Start the server automatically with Systemd (Recommended)

• $ cp /home/steam/longvinter-linux-server/longvinter.service /etc/systemd/system/longvinter.service
• $ systemctl daemon-reload

Now, how to use it:

• $ systemctl start longvinter.service (Starts the server)
• $ systemctl stop longvinter.service (Stops the server)
• $ systemctl restart longvinter.service (Restart the server, for example, if you made a change to Game.ini)
• $ systemctl enable longvinter.service (Everytime you reboot the machine it starts on boot)
• $ systemctl status longvinter.service (Checks the latest 20 lines on the server console)

If the console shows these lines at the bottom after startup your server has started corretly

Updating the server

We have created an automated script that you can run to automatically update and restart a server.

• bash /home/steam/longvinter-linux-server/LongvinterUpdate.sh

Backing up your saves

We have created an automated script that you can run to automatically backup and restart a server, for now it has to be run manually and it requires user input.

• bash /home/steam/longvinter-linux-server/LongvinterBackup.sh
