I wanted to host my own dedicated server for Unturned 3.0 on VPS.
In this case, I used Ubuntu but you can run it on Windows/any Linux OS/macOS almost in the same way (like .sh or .bat).
Env
- Ubuntu 20.04
What I did
Install steamcmd
ref: SteamCMD#Downloading_SteamCMD
$ sudo add-apt-repository multiverse
$ sudo dpkg --add-architecture i386
$ sudo apt update
$ sudo apt install lib32gcc1 steamcmd
Install Unturned dedicated Server using steamcmd
$ steamcmd
Steam>login anonymous
Steam>app_update 1110390
Steam>exit
That commands creates files under ~/.steam/SteamApps/common/U3DS.
Host a dedicated server
There is ./ExampleServer.sh in the directory.
You can run a LAN server using it.
$ cd ~/.steam/SteamApps/common/U3DS
$ ./ExampleServer.sh
But you may want to run Internet Server. So you should change command options a little bit.
$ cp ./ExampleServer.sh MyServer.sh
$ vi MyServer.sh
There are comments in the shellscript. So you can tell what todo.
This is my command in MyServer.sh.
./ServerHelper.sh -Port/27015+InternetServer/MyServer
Then run MyServer.sh.
$ ./MySrever.sh
When you ran it, and if you specified the server ID as MyServer (like InternetServer/MyServer), new directory should be created like ./Servers/MyServer.
In that directory, you can change server preference, like servername, password, map, cheating, mods, whitelist.
Connect to the server
Play -> Servers -> Connect
Steam Network Authentication
If you have problem with steam network authentication, you should VERIFY INTEGRITY OF GAME FILES.... from steam Unturned Game properties.
