Steam lists it as **VEIN Dedicated Server** (app ID `2131400`), and you can download it without owning VEIN. It runs your world around the clock, with no player needed as host, and you configure it through two text files and a handful of launch flags. Ramjet Studios documents the basics in its server-hosting pages, but it doesn't offer support for them, and it won't recommend any hosting company. This page covers both routes. First, what each setting on a GameServerKings VEIN server does and what to change after the first start. Then the self-hosting steps from Ramjet's documentation, for anyone running the server on their own machine. > [!NOTE] Checked against > **VEIN 0.025** (26 September 2026), Ramjet's server-hosting documentation, and the GameServerKings VEIN server configuration on the same day. ## VEIN server at a glance | | | |---|---| | Steam app | `2131400` (anonymous SteamCMD login works) | | Ports | UDP `7777` for gameplay, UDP `27015` for the Steam query. Change them with `-Port=` and `-QueryPort=` | | Main config | `Vein/Saved/Config/LinuxServer/Game.ini` (`WindowsServer` on Windows) | | Gameplay settings | `vein.*` console variables, set from the in-game admin menu or an `[ConsoleVariables]` block in `Engine.ini` | | Admins | SteamID64s in `Game.ini`. There's no admin password | | Console output | Only if you start the server with `-log` | ## Your GameServerKings VEIN server Your server runs the Linux build (`Vein/Binaries/Linux/VeinServer-Linux-Test`) and starts it with `-Port`, `-QueryPort` and `-log` already set. You don't have to install anything. The **Startup** tab in the panel has these settings: | Startup setting | Default | What it does | |---|---|---| | **Server Name** | `Vein Server` | The name in VEIN's server browser. Up to 64 characters | | **Server Password** | empty | Players must enter it to join. The panel accepts 4 to 32 letters, numbers, dashes and underscores. Since January 2026, VEIN passwords are case-sensitive | | **Max players** | `16` | Player slots | | **Public Server** | `True` | Meant to control whether the server is listed in the server browser, but it may not take effect on the current VEIN build. If the server must stay private, set a password as well, or contact support | | **Auto update** | on | Updates VEIN through SteamCMD every time the server starts | | **Query Port** | `27015` | Read-only. We set it for you | Every time the server starts, the panel writes the name, password, player count, query port and bind address into `Game.ini`. Always change those five on the Startup tab. If you edit them in the file, your change disappears on the next restart. Everything else in `Game.ini` belongs to you, and the panel leaves it alone. ## First-start checklist Start the server once so it creates its files, then **stop** it and open **Files** > `Vein/Saved/Config/LinuxServer/Game.ini`. These are the lines worth setting, all from Ramjet's config documentation: ```ini [/Script/Vein.VeinGameSession] ServerDescription=PvE server. No raiding. Restarts 06:00 UTC. SuperAdminSteamIDs=76561198000000001 AdminSteamIDs=76561198000000002 [/Script/Vein.VeinGameStateBase] WhitelistedPlayers=76561198000000001 +WhitelistedPlayers=76561198000000002 [/Script/Vein.ServerSettings] DiscordChatWebhookURL="https://discord.com/api/webhooks/..." ``` - **Replace the placeholder admin.** The default file ships with `AdminSteamIDs=1234`. Put your own 17-digit SteamID64 there, or under `SuperAdminSteamIDs` if you want to promote other admins from inside the game. Extra IDs go on new lines that start with `+`. Our [VEIN console commands guide](/knowledge-base/vein/vein-console-commands/) covers admin setup and the admin menu in detail. - **`ServerDescription`** is shown when a player selects your server in the browser. Use it for rules and your Discord link. - **`WhitelistedPlayers`** (VEIN 0.023 and later) locks the server to the listed SteamIDs. Leave the section out to let anyone join. - **`DiscordChatWebhookURL`** forwards in-game global chat to a Discord channel. Create the webhook in Discord (channel settings > Integrations > Webhooks) and keep the URL in quotes. `DiscordChatAdminWebhookURL`, set in the same section, sends admin reports to a separate channel. Save the file and start the server. Gameplay settings (PvP, loot scarcity, zombie numbers, XP rate and the rest) aren't in `Game.ini`. Change them live from the `\` admin menu's **Config** section. If you want one of them to be the server's default, send support the `vein.` lines you want and we'll add them for you. ## How players join - **Server browser:** search for your server name. The browser shows player counts, ping and the server's settings. - **Direct connect:** since 0.023 the server browser has a **direct connect** button. Enter the IP address and port from the top of your panel. This works even if the server isn't listed. Players' Steam clients update VEIN on their own. The server's **Auto update** setting only installs a patch when the server starts, so restart it after a patch comes out to keep it on the same build as your players. ## Saves and moving a world Take a [backup](/knowledge-base/general/how-to-create-a-backup/) from the panel before any big change. Two things to know if you move a world between servers: - Since 0.016 Hotfix 5, dedicated servers **don't store settings in the save**. They keep them in console variables. A world you move to a new server takes on that server's settings, so set them again afterwards. - Unreal Engine removes config lines that only repeat a default value. If a line you added disappears after a restart, check whether you set it to the default. If you did, nothing is wrong. ## Hosting a VEIN dedicated server yourself If you're running it on your own hardware, these are the steps from Ramjet's documentation: **Linux (Ubuntu shown)** ```bash sudo add-apt-repository multiverse; sudo dpkg --add-architecture i386; sudo apt update sudo apt install steamcmd steamcmd +force_install_dir ~/vein +login anonymous +app_update 2131400 validate +quit ``` Then link Steam's `steamclient.so` into the server's `Vein/Binaries/Linux` folder, as Ramjet's guide describes. If the log shows `dlopen failed trying to load … .steam/sdk64/steamclient.so`, copy or link SteamCMD's `linux64/steamclient.so` to `~/.steam/sdk64/`. **Windows:** download SteamCMD from Valve, extract it, and run `steamcmd.exe +force_install_dir C:\vein +login anonymous +app_update 2131400 validate +quit`. If a Windows server doesn't appear in the browser and the log says the Steam dedicated server API failed to initialise, Ramjet suggests running it with administrator rights. **Starting it:** run `VeinServer` with `-log`, and open UDP `7777` and `27015` on your firewall and router. The server is ready when the log shows `SDR RelayNetworkStatus: avail=OK`. Other launch options Ramjet documents: | Flag | Use | |---|---| | `-Port=7777` / `-QueryPort=27015` | Change the game and query ports. Don't forget the `=` | | `-multihome=` | Bind to one IP address on a machine that has several | | `-onethread` | Run single-threaded, useful when one machine hosts several servers | | `+app_update 2131400 -beta experimental` | Install the experimental branch (a SteamCMD option, not a launch flag) | To update, run the same SteamCMD line again. Gameplay settings go in `Engine.ini`, in the same folder as `Game.ini`, under a `[ConsoleVariables]` header. Ramjet also documents an optional HTTP API. Adding `HTTPPort=8080` to `Game.ini` makes the server answer `GET /status`, `/players` and `/weather` with JSON. It has **no authentication**, so don't expose that port to the internet. On a GameServerKings server it would need an extra port, so contact support if you want to use it. ## Troubleshooting - **Your `Game.ini` change disappeared.** You edited the name, password, player count or ports in the file. Change those on the Startup tab. - **You can't use the admin menu.** Your SteamID64 isn't in `AdminSteamIDs` or `SuperAdminSteamIDs`, or it's on a second line without the leading `+`. Restart after editing. - **Friends get a password error.** Passwords are case-sensitive and can only contain letters, numbers, dashes and underscores. - **The server isn't in the browser.** Use direct connect with the address from your panel. See [players can't connect](/knowledge-base/general/players-cant-connect/) if that fails too. - **Players can't join right after a VEIN patch.** Restart the server so Auto update installs the same build your players have. ## What to Read Next - [VEIN console commands, admin menu and server settings](/knowledge-base/vein/vein-console-commands/): admin setup and every `vein.*` setting - [VEIN mods](/knowledge-base/vein/vein-mods/): what works on your PC and on a dedicated server - [How to use your server panel](/knowledge-base/general/how-to-use-your-server-panel/): Startup, Files and the console - [How to create a backup](/knowledge-base/general/how-to-create-a-backup/): before moving or wiping a world --- Made with 💜 by GameServerKings
