What are the system requirements for a CS2 dedicated server?

A CS2 dedicated server requires at least 2 CPU cores, 4 GB RAM, and 50 GB disk space. For 10-player competitive matches, 4 cores and 8 GB RAM is recommended. Ubuntu 22.04 LTS or later is the preferred OS.

How do I use RCON to manage my CS2 server?

Set rcon_password in your server.cfg, then use the in-game console with 'rcon_address :27015' and 'rcon_password ' to authenticate. You can then run any server command remotely such as changelevel, kick, ban, and status.

Can I add custom maps to my CS2 server?

Yes. CS2 supports Steam Workshop maps. Add the Workshop map collection ID to your server startup parameters with +host_workshop_collection or use +map workshop/ to load a specific Workshop map directly.

What is SourceTV and how does it work?

SourceTV is Valve's built-in broadcast system that allows spectators to watch live matches with a delay. It runs on port 27020 and spectators connect using the CS2 console command 'connect :27020'. It is useful for tournaments and streaming.

How do I whitelist players or set a password on my CS2 server?

Set sv_password in server.cfg to require a password for joining. For Steam-only access, use sv_steamgroup and sv_steamgroup_exclusive. For a private server with specific players, use the steam whitelist via the server configuration.

📦 Resources & Setup Scripts

Grab the automated bash script from GitHub to follow along with the video.

Quick Install:

wget https://raw.githubusercontent.com/mhmdali94/Docker/main/gaming/cs2/cs2-ubuntu.sh
chmod +x cs2-ubuntu.sh
sudo bash cs2-ubuntu.sh

Tutorial Steps

1 Download & Run the Installer

The script installs Docker if needed, downloads the CS2 dedicated server via SteamCMD, and starts the server container. The initial download is approximately 30 GB so allow time for it to complete.

wget https://raw.githubusercontent.com/mhmdali94/Docker/main/gaming/cs2/cs2-ubuntu.sh
chmod +x cs2-ubuntu.sh
sudo bash cs2-ubuntu.sh

2 Configure the Server

Edit the server configuration file to set your server name, password, round settings, and RCON password for remote administration.

# Edit server.cfg
nano /opt/cs2/game/csgo/cfg/server.cfg

# Key settings to configure:
hostname "My CS2 Server"
sv_password ""
mp_maxrounds 30
rcon_password "your_rcon_password_here"

3 Connect with the Game Client

Open CS2 and connect to your server via the community server browser or the developer console.

# Option 1: In-game console (press ~)
connect <your-server-ip>:27015

# Option 2: Community Servers browser
# CS2 → Play → Community Servers → search server name

4 Admin Management

Use RCON to manage your server remotely — change maps, kick or ban players, and review server logs.

# Authenticate RCON from CS2 console
rcon_address <your-server-ip>:27015
rcon_password your_rcon_password_here

# Common RCON commands
rcon status                      # list connected players
rcon changelevel de_dust2        # change map
rcon kick <player_name>          # kick a player
rcon banid 0 <steam_id> kick     # ban a player
rcon mp_restartgame 1            # restart the match

Overview

Counter-Strike 2 (CS2) is Valve's tactical FPS and the successor to CS:GO. A dedicated server allows you to host private 5v5 competitive matches, practice servers, casual games, or community servers with custom configs and plugins.

Why Use It

Self-hosting a CS2 server gives you a private practice environment, custom server settings, low-latency matches for your team, and no trust factor restrictions. You can configure custom plugins via CounterStrikeSharp for warmup bots, practice mode, and other utilities.

Security Best Practices

Ports and Firewall Notes

CS2 uses UDP port 27015 for game connections. Open UDP port 27015. TCP port 27015 is used for RCON — keep this firewalled. The Steam server browser query also uses the same port range.

Troubleshooting

Alternatives

Alternatives include Valve-operated matchmaking (official, no setup), FACEIT (third-party competitive platform), and Leetify servers (practice focused). Self-hosting provides a private low-latency server with full plugin customization.

When Not to Use It

Avoid self-hosting if you want proper anti-cheat and competitive matchmaking — Valve MM and FACEIT provide better environments for ranked play. Self-hosted servers are best for practice, community games, and custom modes.

Frequently Asked Questions

What is CounterStrikeSharp?

CounterStrikeSharp (CSS) is a plugin framework for CS2 servers written in C#. It replaces the old Sourcemod/Metamod system from CS:GO. Plugins built on CounterStrikeSharp add features like practice mode, matchmaking plugins (MatchZy), warmup bots, stat tracking, and custom game modes.

Can I run workshop maps on my CS2 server?

Yes. CS2 supports Steam Workshop maps. Download maps using the workshop ID and configure your server to load them. Players connecting to your server need to have the workshop map downloaded too, either automatically via the server or manually subscribing on the Workshop.

Can I use my CS2 server for a private team practice?

Yes — this is a primary use case. Set sv_password in server.cfg to a private password. Configure a competitive map (de_dust2, de_mirage, etc.) and knife round plugin. Install MatchZy plugin for professional match setup with ready checks, knife rounds, team names, and match recording.

How do I add bots to my CS2 server?

Use the bot_add command in the server console, or configure it in server.cfg with bot_quota and bot_difficulty (0-3). For a deathmatch with bots, set bot_quota to your desired count. You can also set teams to be entirely bots for solo practice sessions.

What server hardware do I need for CS2?

For a 10-player server, 2 CPU cores at 2+ GHz and 4 GB RAM is sufficient. CS2 dedicated server is lighter than the client. For a 20-player community server, use 4 cores and 8 GB RAM. Tick rate configuration (64 tick or 128 tick) slightly affects CPU and bandwidth requirements.
