How to Let Your Friends Dominate the CS:GO Server with You

So, you’ve got your CS:GO server up and running, and now you’re itching to unleash chaos with your friends. Excellent choice! Getting your buddies into the game is simpler than defusing a bomb with 0.01 seconds left, but there are a few pathways to consider depending on the type of server you’re running.

Here’s the breakdown, covering both private servers and community servers:

Private Servers (Your Own Dedicated Server)

This is the classic route, offering the most control. You’re essentially hosting the game yourself. Here’s how to get your friends connected:

  1. Ensure Server is Publicly Accessible: This is crucial. If your server is behind a firewall or on a local network, your friends outside that network won’t be able to connect. You’ll likely need to configure port forwarding on your router. Port forwarding tells your router to direct traffic on a specific port (usually 27015 for CS:GO) to your server’s internal IP address. Google “port forwarding [your router model]” for specific instructions.
  2. Disable sv_lan: If you created the server through the in-game menu, it might default to LAN mode (sv_lan 1). Open the server console (usually accessed by pressing the ~ key) and type sv_lan 0 then press enter. This makes the server accessible from the internet.
  3. Obtain Your Server’s Public IP Address: Type status in the server console and press enter. Look for the line starting with “IP address:”. The IP address listed here is what your friends will need.
  4. Share the Connection Information: Tell your friends your public IP address and the port number (usually 27015). They’ll use this information to connect.
  5. Connection Command: Your friends will open their CS:GO console (enable it in the game settings if it’s not already) and type connect [your IP address]:[port number]. For example: connect 123.45.67.89:27015.

Important Considerations for Dedicated Servers:

  • Firewall: Make sure your firewall (both on your server machine and your router) isn’t blocking the CS:GO port (27015).
  • Server Tickrate: This affects the server’s responsiveness. A higher tickrate (e.g., 128) provides a smoother experience but requires more processing power. Configure this in your server’s configuration file.
  • Server Configuration: Familiarize yourself with the server.cfg file. This is where you set server rules, map rotations, passwords, and other settings.
  • RCON Password: Set an RCON password for remote server administration. This allows you to manage the server from outside the game.

Community Servers (Joining Existing Servers)

If you’re looking to play on an existing community server with your friends, the process is much simpler:

  1. Find a Server: Use the CS:GO server browser to find a server you and your friends want to play on. Note the server’s name or IP address.
  2. Join the Server: One of you joins the server.
  3. Invite Your Friends: Open your Steam friends list (Shift+Tab in-game), right-click on your friend’s name, and select “Invite to Game.” This will send them an invitation to join the server you’re currently playing on.
  4. Alternatively, share the IP Address: You can also share the server’s IP address with your friends, and they can connect directly using the connect command in the console (as described above).

Using Steam Groups for Easier Lobbies

CS:GO allows you to create and use Steam groups for easier lobby management:

  1. Create a Steam Group (if you don’t have one): On Steam, go to “Groups” and create a new group for you and your friends.
  2. Set Clan Tag (Optional but Recommended): Set the group’s tag as your in-game clan tag. This will visually identify you as a group.
  3. Create a Lobby: In CS:GO, click “Play,” then “Play with Friends.”
  4. Change Permissions: On the lobby screen, click “Change Permissions” and select “Public Steam Group Lobby.” Choose your Steam group from the list.
  5. Invite Your Friends: Invite your friends to the lobby. Now, anyone in the Steam group can easily find and join your lobby.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to help you further troubleshoot and optimize your CS:GO server experience:

1. My friends can’t connect, even after port forwarding. What’s wrong?

Double-check your port forwarding settings. Ensure the correct internal IP address of your server machine is specified, and that the port number is correct (usually 27015). Also, verify that your firewall isn’t blocking the port. Some ISPs may also block certain ports; contact them to confirm.

2. How do I set a password for my server?

In your server.cfg file, add the line sv_password "yourpassword" (replace “yourpassword” with your desired password). Restart the server for the changes to take effect. Players will need to enter the password in the console using the password "yourpassword" command before connecting.

3. How do I give someone admin on my CS:GO server?

This requires installing a server mod like SourceMod. SourceMod allows you to manage your server and grant admin privileges. The process involves:

  1. Installing SourceMod.
  2. Editing the admins_simple.ini file (usually located in cfg/sourcemod/admins_simple.ini).
  3. Adding the player’s SteamID64 along with their desired admin flags.

For example: "76561198000000000" "99:z" (This gives the player all admin rights).

4. What is a SteamID64, and how do I find it?

A SteamID64 is a unique identifier for each Steam account. You can find it using online SteamID lookup tools. Just enter your Steam profile URL or username, and the tool will provide your SteamID64.

5. How do I change the map on my server?

In the server console, type map [mapname] (e.g., map de_dust2). You can also set up a map rotation in your server.cfg file using the mapcycle.txt file.

6. How do I change the server name?

In your server.cfg file, add the line hostname "Your Server Name" (replace “Your Server Name” with your desired name). Restart the server for the changes to take effect.

7. What is a “tickrate,” and what’s the best value?

The tickrate is the number of times per second the server updates the game state. A higher tickrate (e.g., 128) results in a smoother and more responsive experience, but it requires more server resources. A tickrate of 64 is generally acceptable, but 128 is preferred for competitive play if your server can handle it.

8. How do I install plugins on my server?

You’ll need to install a server mod like SourceMod to use plugins. Once SourceMod is installed, you can download plugins from various sources (e.g., AlliedModders) and place them in the plugins folder within your SourceMod directory.

9. How do I prevent cheaters on my server?

Enable VAC (Valve Anti-Cheat) by ensuring sv_cheats 0 is set in your server.cfg file. Consider using server mods like AC (Anti-Cheat) or SMAC (SourceMod Anti-Cheat) for additional protection. Actively monitor your server and ban suspicious players.

10. Can I run a CS:GO server on my home computer?

Yes, you can, but performance will depend on your computer’s specifications and your internet connection. A dedicated server is generally recommended for a smoother experience, especially with multiple players.

11. How do I update my CS:GO server?

The simplest way is usually through the SteamCMD (Steam Console Client). You’ll need to use specific commands to log in to your Steam account, specify the CS:GO server app ID, and update the server files. Numerous online tutorials provide detailed instructions for using SteamCMD to update your CS:GO server.

12. My server is lagging. What can I do?

Lag can be caused by various factors, including insufficient server resources (CPU, RAM), a slow internet connection, or a high number of players. Try reducing the tickrate, limiting the number of players, or upgrading your server hardware. Monitor your server’s CPU and RAM usage to identify bottlenecks.

13. How do I create a mapcycle.txt file?

A mapcycle.txt file lists the maps that will be rotated on your server. Each map name should be on a separate line. You can then specify this file in your server.cfg file using the command mapcyclefile "mapcycle.txt".

14. How do I enable or disable friendly fire?

Use the command mp_friendlyfire 1 (enable) or mp_friendlyfire 0 (disable) in your server console or server.cfg file.

15. Where can I learn more about server configuration and management?

The Games Learning Society website offers great resources for learning about game development and server management. Check out GamesLearningSociety.org for insightful articles and community discussions. Additionally, the AlliedModders forums are a valuable resource for SourceMod and server plugin information.


Setting up and managing a CS:GO server can seem daunting at first, but with a little patience and the right resources, you can create a fantastic gaming experience for you and your friends. Good luck, and happy fragging!
