To host a Longvinter server, install the dedicated server with SteamCMD (app 1639880), stop it, and edit Longvinter/Saved/Config/LinuxServer/Game.ini (or WindowsServer on Windows): ServerName, MaxPlayers, Password, PVP, TentDecay, MaxTents and AdminSteamID. Forward UDP 7777 plus 27016 for the server list, start it, and players join from the server browser or Connect by IP. Always edit with the server stopped, because a running server writes its config back over your changes.
What do you need to run a Longvinter server?
Longvinter is light for an Unreal Engine game. Uuvana lists a 64 bit OS, at least 3 GB of RAM and a CPU around 3 GHz as the minimum. Each player needs their own copy; the server is a free download.
| Group | RAM | Notes |
|---|---|---|
| A few friends, private island | 4 GB | Small village, PvE |
| Community server with regulars | 6 GB | 10 to 20 active players |
| Public server near 32 slots | 8 GB | Many camps and tents across the map |
Tents and camps are what grow over time, so TentDecay and MaxTents matter as much as the plan size on a busy server.
How do I install the Longvinter dedicated server?
The server used to be a GitHub download. Uuvana now ships it through Steam, so use SteamCMD:
steamcmd +force_install_dir ~/longvinter-server +login anonymous +app_update 1639880 validate +quit
On Windows the same line works with C:\steamcmd\steamcmd.exe and a folder like C:\longvinter-server. Start it with ./LongvinterServer.sh on Linux or LongvinterServer.exe on Windows. The game port can be changed with -GamePort=7777 on the start line.
Run the same app_update 1639880 command after each game update, then restart, or players on the new version cannot join.
What goes in Game.ini?
Stop the server, then create or open Game.ini in Longvinter/Saved/Config/LinuxServer/ (WindowsServer on Windows). It has two sections:
[/Game/Blueprints/Server/GI_AdvancedSessions.GI_AdvancedSessions_C]
ServerName=Pinecone Bay
ServerMOTD=Welcome to Pinecone Bay, no stealing
MaxPlayers=32
Password=pinecone42
CommunityWebsite=discord.gg/yourgroup
ServerTag=PVE
CoopPlay=false
CheckVPN=true
CoopSpawn=0
ChestRespawnTime=600
DisableWanderingTraders=false
[/Game/Blueprints/Server/GM_Longvinter.GM_Longvinter_C]
AdminSteamID=00023652dd9b4673be20d4f83ab42c5b
PVP=false
TentDecay=true
MaxTents=2
RestartTime24h=6
SaveBackups=true
| Key | What it does | Default and tips |
|---|---|---|
ServerName |
Name in the server browser | Do not use the word OFFICIAL |
ServerMOTD |
Message shown on signs around the island | Short house rules work well |
MaxPlayers |
Player cap | Default 32 |
Password |
Join password | Letters and numbers only |
CommunityWebsite |
Link players can open in game | Your Discord |
ServerTag |
One search tag | PVE for peaceful servers |
CoopPlay, CoopSpawn |
Cooperative play mode and its spawn point | Default false and 0 |
CheckVPN |
Checks connecting players for VPNs | Default true |
ChestRespawnTime |
Seconds until loot chests refill | Default 600 |
DisableWanderingTraders |
Stops wandering traders spawning | Default false |
AdminSteamID |
Admin IDs, separated by a single space | EOS IDs, see below |
PVP |
Player versus player combat | Default true |
TentDecay |
Removes abandoned tents | Default true |
MaxTents |
Tents each player can place | Default 2 |
RestartTime24h |
Daily restart hour, 24 hour clock | For example 6 |
SaveBackups |
Daily backups to two folders | Default false, turn it on |
If the server shows up in the wrong region, add ServerRegion= with EU, NA, SA, AS or AU. Every key is documented on Uuvana's server configuration page.
How do I make myself an admin?
Despite the name, AdminSteamID does not take a Steam ID. It takes your EOS account ID, a 32 character string of letters and numbers. Find it in game under Options > General, copy it exactly, and put it after AdminSteamID=. Add more admins on the same line, separated by one space. Restart the server afterwards.
The gotcha: edits that vanish
Longvinter's own server FAQ is blunt about this: if your configuration changes are not applied, you edited the file while the server was running. The server saves every 10 minutes and writes its settings back as it does, so an edit made on a live server is overwritten at the next save or on shutdown. The fix is always the same:
- Stop the server completely.
- Edit
Game.iniand save it. - Start the server.
The same applies to password problems: a password with a symbol in it breaks joining, so stick to letters and numbers.
What ports does a Longvinter server use?
| Port | Protocol | Used for |
|---|---|---|
| 7777 | UDP | Game traffic, the port players join on |
| 27016 | TCP and UDP | Server list query |
Uuvana specifically says not to bother opening TCP 7777, because Unreal Engine game traffic is UDP. Join by IP with the game port, not the query port. Our port forwarding guide covers the router side.
How do players join a Longvinter server?
- Open the Server Browser in Longvinter.
- Search for the server name, or filter by your tag, for example
PVE. - To skip the list, click Connect by IP at the top right and enter the IP and game port, for example
203.0.113.10:7777. - Enter the password if there is one.
A new server can take a few minutes to appear in the browser. Connect by IP works straight away.
PvP or PvE: which rules to pick
PvP is on by default, which means players can raid camps and steal. For a calm fishing village set PVP=false, ServerTag=PVE and a MOTD that says so. For a PvP server keep MaxTents low and TentDecay=true, so abandoned camps disappear and new players have room. Longvinter has no mod support, so these keys and your rules are how a server gets its character.
Moving an existing island onto it
Uuvana's own backup method copies the whole Longvinter/Saved folder, which holds the world as well as the config. To move an island from another machine, stop both servers, copy Longvinter/Saved across, and then check Game.ini again on the new server, since name, password and admin IDs travel with it. Back up the new server's folder before you overwrite it. More on keeping copies: how to restore a backup on a game server.
Common problems
- Settings reset after a restart: the file was edited while the server ran. Stop, edit, start.
- Server missing from the browser: UDP 7777 or port 27016 is closed, or the server is still registering. Use Connect by IP meanwhile.
- Admin commands do nothing: a Steam ID was used instead of the EOS ID from Options > General.
- Password rejected: it contains a symbol. Use letters and numbers only.
- Players kicked after an update: the server is on the previous version. Update with SteamCMD and restart.
FAQ
How many players can join a Longvinter server?
The default MaxPlayers is 32, and you can change it in Game.ini. More players means more camps, so give the server more RAM as you raise it.
How do I turn off PvP on a Longvinter server?
Set PVP=false in Game.ini with the server stopped, then start it. Add ServerTag=PVE so peaceful players can find you.
Why are my Longvinter server settings not saving?
The server overwrites Game.ini while it runs. Stop it completely, edit the file, then start it.
Does Longvinter have mods?
No. There is no mod support, so servers are shaped through Game.ini settings and house rules.
The easy option: host it with us
Longvinter hosting on GamezServers starts at 9.99 USD a month for 4 GB, with 6 GB and 8 GB plans for bigger islands and 50% off the first month for new customers. Our panel writes the server name, tag, MOTD, community link, max players, password, admin IDs, PvP, tent decay and max tents into Game.ini each time the server starts, so change those in the panel and the rest (like ChestRespawnTime or SaveBackups) in the file manager with the server stopped. There is a one click Backup before updates, SFTP for moving an island in, and the group can split the bill.
Skip the setup. Your own Longvinter server.
