To set up an open.mp server on FREAKHOSTING, open your server in the [Game Panel](https://games.freakhosting.com), click **Game settings**, enter a **Server name**, optionally set a **Server password**, click **Review and save**, then **Save changes** and restart. The server is ready when the console shows `Legacy Network started on port`. Players join with the address from **Overview**, using the open.mp launcher or the SA-MP 0.3.7 client. | Difficulty | Time | Works on | Panel page | | - | - | - | - | | Beginner | 5 to 10 minutes | Every FREAKHOSTING open.mp server | **Game settings** | ## Before you start * Log in to the [Game Panel](https://help.freakhosting.com/portals/game-panel/how-to-login-and-access-the-game-panel.md). * Have Grand Theft Auto: San Andreas for PC and the [open.mp launcher](https://open.mp/downloads/launcher) installed. The launcher also joins SA-MP servers. * Your server runs the open.mp server with the example game mode `gungame`, so it works before you change anything. ## What is open.mp? open.mp (open.multiplayer) is a multiplayer mod for Grand Theft Auto: San Andreas that is backwards compatible with SA-MP. According to the [open.mp project](https://open.mp/), old SA-MP `.amx` scripts load on the open.mp server without changes, and players on the SA-MP client can join. Settings live in `config.json`, which the **Game settings** page edits for you. ## How to set up your open.mp server **1. Open Game settings** Open your server and click **Game settings** under **GAME SETTINGS**. The **Checks** row says `Nothing to fix.` when the settings are valid. **2. Name your server** In the **Server** section, enter a **Server name**. This is what players see in the server browser. It can be up to 178 characters. **3. Set a password (optional)** Next to **Server password**, click **Set** and enter a password if only invited players should join. Leave it empty for an open server. See [set a password](https://help.freakhosting.com/games/open-mp/how-to-set-a-password-on-your-open-mp-server.md). **4. Choose visibility** Leave **Show in the server list** on to be listed in the open.mp and SA-MP server lists, or turn it off so players can only join with the address. **5. Review and save** Click **Review and save**. The **Review your changes** dialog shows exactly what changes in `config.json`. Click **Save changes**. **6. Restart the server** Click **Restart now** on the yellow banner, or [restart the server](https://help.freakhosting.com/portals/game-panel/how-to-start-stop-and-restart-your-game-server.md). Watch the [console](https://help.freakhosting.com/portals/game-panel/how-to-use-the-server-console.md) until it shows `[Info] Legacy Network started on port` followed by your port. This takes a few seconds. ![open.mp Game settings page with the Server section, Server name, Player slots, Server password and the restart banner](https://mintcdn.com/freakhostingltd/m3ZOEtGPuZd9DW2_/images/games/open-mp/openmp-game-settings.png?fit=max\&auto=format\&n=m3ZOEtGPuZd9DW2_\&q=85\&s=7ea147a744f2ee67b3f931d16c6eac17) Game settings for open.mp in the FREAKHOSTING Game Panel ## How to join your open.mp server **1. Copy the address** On **Overview**, copy the **ADDRESS** under the server info (the copy icon next to it). It is your IP and port, for example `203.0.113.10:7777`. **2. Add it in the launcher** Open the open.mp launcher (or the SA-MP 0.3.7 client), add the address to your favourites and connect. **3. Enter the password** If you set a **Server password**, the game asks for it when you join. ## How many players can join? Your player slots come from **Max Players** on **Startup**, which shows the slots in your plan. The panel writes it into `config.json` at every start, so changing **Player slots** in **Game settings** has no effect. To get more slots, [open a ticket](https://freakhosting.com/clientarea/submitticket.php). ## Make your first backup Before you upload your own game mode or plugins, make a [panel backup](https://help.freakhosting.com/portals/game-panel/how-to-create-and-restore-backups.md). When you save in **Game settings**, the panel also keeps the previous file as `config.json.bak`. ## Frequently asked questions ### What port does my open.mp server use? It uses the port shown on **Overview** in the Game Panel. The open.mp default is 7777, but your server may use a different port, so always join with the address from the panel. ### Do players need the open.mp launcher? No. The open.mp launcher is recommended, but **Allow 0.3.7 clients** is on by default, so players with the older SA-MP 0.3.7 client can also join. ### How do I become admin on my open.mp server? Turn on **Enable RCON** in **Game settings**, restart, then type `/rcon login yourpassword` in game. See [RCON commands and admin login](https://help.freakhosting.com/games/open-mp/open-mp-rcon-commands-and-admin-login.md). ### How do I change the game mode? Upload your compiled `.amx` file to `gamemodes/` and enter its name in **Game modes**. See [install a gamemode](https://help.freakhosting.com/games/open-mp/how-to-install-a-gamemode-and-filterscripts-on-open-mp.md). ### Can I still run a SA-MP server instead? Yes, open.mp and SA-MP are separate products. If you already run SA-MP, see our [SA-MP server guide](https://help.freakhosting.com/games/samp/samp-server-hosting-guide.md) or [migrate to open.mp](https://help.freakhosting.com/games/open-mp/how-to-migrate-a-samp-server-to-open-mp.md). ## Related guides > [card] [open.mp server guide](https://help.freakhosting.com/games/open-mp/open-mp-server-hosting-guide.md) > > Every open.mp page in one place. > [card] [Change server settings](https://help.freakhosting.com/games/open-mp/how-to-change-open-mp-server-settings.md) > > Game settings, presets and saving. > [card] [Install a gamemode](https://help.freakhosting.com/games/open-mp/how-to-install-a-gamemode-and-filterscripts-on-open-mp.md) > > Your own game mode and filterscripts. > [card] [RCON and admin login](https://help.freakhosting.com/games/open-mp/open-mp-rcon-commands-and-admin-login.md) > > Turn on RCON and log in. > [card] [Not showing in the list](https://help.freakhosting.com/games/open-mp/open-mp-server-not-showing-in-server-list.md) > > Find your server or join by IP. *** > [!NOTE] > > **Tested by the FREAKHOSTING team** on our Game Panel on 3 November 2026 (open.mp server 1.6.7.3218).
