Counter-Strike 2 Dedicated Server Setup

Everything you need to run a real Counter-Strike 2 dedicated server on Linux in 2026 — GSLT, SteamCMD, server.cfg presets for competitive / DM / retake / 1v1 / community, CounterStrikeSharp plugin support (MetaMod + CSS, not SourceMod), Workshop map collections, SourceTV demos, FastDL for custom maps, and a troubleshooting table for the errors everyone actually hits.

01 // Requirements

CS2 is much lighter than Rust or ARK, but tickrate and plugin overhead still matter. Pick hardware based on the kind of server you want to run:

• Operating System — Ubuntu 22.04 LTS or 24.04 LTS (Debian 12 works identically). CS2 dedicated server is Linux/Windows only; Linux is the canonical host.
• Architecture — x86_64 only. CS2 does not run on ARM. Ignore VPS offers with Ampere or Graviton CPUs for this.
• RAM — 4 GB minimum for a single 10-slot competitive server. 8 GB comfortable with plugins, SourceTV, and a second instance.
• CPU — 1 fast modern core per server instance. CS2 is single-thread bound for the tick loop. Clock speed beats core count. Aim for Ryzen 7xxx or Intel 12th gen+.
• Storage — 60 GB SSD. CS2 install is ~35 GB and Workshop maps + demos grow fast.
• Network — 1 Gbps port, unmetered preferred. UDP 27015 open inbound, HTTPS outbound to Steam.
• GSLT — Game Server Login Token, free, one per server. Required for public servers. Generate at steamcommunity.com/dev/managegameservers. App ID 730.
• Root / sudo — only for the initial setup; the server itself runs as a non-root user (we’ll create cs2).

Hardware scenarios — pick your tier

02 // Pick your server type

Before you write a single line of server.cfg, decide what you’re actually running. The cfg for a ranked 5v5 comp server looks nothing like a 1v1 arena or a bhop server. Use the picker below to get a baseline preset — the full cfg details come in section 5.

03 // Get a GSLT (Game Server Login Token)

A GSLT is a free, per-server token from Steam that authenticates your dedicated server as a legitimate CS2 game server. Without it:

• Your server won’t appear in the public community browser.
• Players outside your LAN may fail to connect (depending on NAT).
• You can’t register for server picker services.

Generating one takes 60 seconds:

1. Go to steamcommunity.com/dev/managegameservers while logged into your Steam account.
2. Fill in App ID: 730 (Counter-Strike 2).
3. Memo: anything descriptive (e.g. hostingbuff-comp-01).
4. Click Create. Copy the token that appears — it looks like a 32-character hex string.

Your Steam account needs to be in good standing: no VAC bans, no Overwatch bans, no recent cooldowns, and Steam Guard enabled. Limited accounts cannot create GSLTs.

04 // Create a non-root user

Never run a game server as root. It’s a security liability and makes SteamCMD file ownership a mess. Create a dedicated user:

# As root or with sudo
adduser --disabled-password --gecos "" cs2
usermod -aG sudo cs2  # optional, remove sudo if you don't want it later

# Switch to the cs2 user for everything that follows
su - cs2

From now on, every command in this guide runs as the cs2 user unless explicitly marked sudo.

05 // Install SteamCMD and CS2

SteamCMD is Valve’s command-line client for downloading dedicated server files. On Debian/Ubuntu you need to enable the multiverse repo and the i386 architecture (some of SteamCMD’s shim libraries are 32-bit even though CS2 itself is 64-bit):

# Back as root / sudo:
sudo dpkg --add-architecture i386
sudo add-apt-repository multiverse -y
sudo apt update
sudo apt install -y lib32gcc-s1 libstdc++6 libstdc++6:i386 steamcmd curl tar wget

# Back to the cs2 user:
su - cs2

# Create directories
mkdir -p ~/steamcmd ~/cs2-server
cd ~/steamcmd

# Fetch SteamCMD (package above provides a launcher, but a local copy is cleaner)
curl -sSL https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz | tar -xz

Download CS2 dedicated server (app 730)

cd ~/steamcmd
./steamcmd.sh +force_install_dir /home/cs2/cs2-server \
  +login anonymous \
  +app_update 730 validate \
  +quit

This pulls ~35 GB from Steam. First run takes 10–30 minutes on a 1 Gbps link. When it finishes you should see Success! App "730" fully installed.

06 // Write your server.cfg

CS2 reads server.cfg from /home/cs2/cs2-server/game/csgo/cfg/server.cfg at map load. Create it:

mkdir -p /home/cs2/cs2-server/game/csgo/cfg
nano /home/cs2/cs2-server/game/csgo/cfg/server.cfg

07 // Launch script and systemd service

CS2’s dedicated binary is game/bin/linuxsteamrt64/cs2. It needs the correct working directory and environment. Wrap it in a launch script so you only edit one file when changing params:

nano /home/cs2/cs2-server/start.sh

#!/bin/bash
# HostingBuff CS2 launch script
cd /home/cs2/cs2-server

# Your GSLT (generated at steamcommunity.com/dev/managegameservers)
GSLT="YOUR_32_CHAR_TOKEN_HERE"

# Launch options
START_MAP="de_dust2"
PORT=27015
CLIENTPORT=27005
TV_PORT=27020
MAX_PLAYERS=10

./game/bin/linuxsteamrt64/cs2 \
    -dedicated \
    -console \
    -usercon \
    +game_type 0 \
    +game_mode 1 \
    +mapgroup mg_active \
    +map ${START_MAP} \
    -port ${PORT} \
    -tv_port ${TV_PORT} \
    -maxplayers_override ${MAX_PLAYERS} \
    +sv_setsteamaccount ${GSLT} \
    -authkey YOUR_WORKSHOP_API_KEY_IF_USING_WORKSHOP

chmod +x /home/cs2/cs2-server/start.sh

systemd service (auto-restart, boot-start)

Running inside tmux or screen is fine for testing, but for production you want systemd — it restarts on crash, starts on boot, and writes logs to the journal:

sudo nano /etc/systemd/system/cs2.service

[Unit]
Description=Counter-Strike 2 Dedicated Server
After=network-online.target
Wants=network-online.target

[Service]
Type=simple

NoNewPrivileges=true

[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload
sudo systemctl enable --now cs2
sudo systemctl status cs2
journalctl -u cs2 -f     # tail live logs

Keeping CS2 updated

Create a simple update script:

nano /home/cs2/update.sh

#!/bin/bash
sudo systemctl stop cs2
/home/cs2/steamcmd/steamcmd.sh \
  +force_install_dir /home/cs2/cs2-server \
  +login anonymous \
  +app_update 730 \
  +quit
sudo systemctl start cs2

chmod +x /home/cs2/update.sh

Run it manually after Valve pushes an update, or wire it to a cron job that polls the Steam API for version changes. Never do unattended auto-updates mid-match — schedule them during off-hours.

08 // Install Metamod:Source and CounterStrikeSharp

This is the part every outdated CS:GO tutorial gets wrong. SourceMod does not work on CS2. The plugin stack you want is:

• Metamod:Source — the low-level loader that hooks CS2’s engine. Required.
• CounterStrikeSharp (CSS) — a .NET 8 runtime that sits on top of Metamod and lets you load C# plugins. Replaces SourcePawn.

Every CS2 plugin in 2026 worth running (MatchZy, Retakes, SharpTimer, CSSAdmin, AntiRush, etc.) is built on CounterStrikeSharp.

Install Metamod:Source (dev build for CS2)

CS2 needs the dev branch of Metamod — the stable 1.12 branch does not support CS2.

cd /tmp
# Get the latest CS2-compatible build from metamodsource.net
# (check https://www.metamodsource.net/downloads.php?branch=dev for current version)
wget https://mms.alliedmods.net/mmsdrop/2.0/mmsource-2.0.0-git1347-linux.tar.gz -O mms.tar.gz
tar -xzf mms.tar.gz -C /home/cs2/cs2-server/game/csgo/
rm mms.tar.gz

Edit the game info file so CS2 actually loads Metamod on startup:

nano /home/cs2/cs2-server/game/csgo/gameinfo.gi

Find the SearchPaths section and add one line above the existing Gamecsgo entry:

SearchPaths
{
    Game_LowViolencecsgo_lv
    Game+Mod            csgo/addons/metamod    // <-- ADD THIS LINE
    Game                csgo
    Game                csgo_core
    Game                csgo_imported
    ...
}

Verify in console when you start CS2:

meta version
meta list

You should see Metamod:Source version 2.x.x-dev. If Unknown command, Metamod didn’t load — re-check the gameinfo.gi edit.

Install CounterStrikeSharp

cd /tmp
# Fetch the latest WITH RUNTIME build (includes .NET 8 runtime bundled - no system dotnet needed)
wget https://github.com/roflmuffin/CounterStrikeSharp/releases/latest/download/counterstrikesharp-with-runtime-build-XXX-linux-latest.zip -O css.zip
# Replace XXX with the current build number from the release page
unzip css.zip -d /home/cs2/cs2-server/game/csgo/
rm css.zip

# Fix permissions
chown -R cs2:cs2 /home/cs2/cs2-server/game/csgo/addons

Restart the CS2 server. In console you should see:

[CSS] CounterStrikeSharp is starting up...
[CSS] Plugin loader: initialized
[CSS] Core API loaded. Version: 1.x.x

Verify Metamod and CSS are loaded

In the CS2 server console (or via rcon):

meta list

Expected output:

Listing 1 plugin:
[01]  "CounterStrikeSharp" (1.x.x) by roflmuffin

If you see that line, you’re ready to install plugins.

Install CounterStrikeSharp plugins

Most CS# plugins install the same way: download, extract, drop folder into addons/counterstrikesharp/plugins/, reload.

# Example: install MatchZy (competitive match automation — knife round, pause,
# stats, .ready / .notready, GOTV forward, veto, etc.)
cd /tmp
wget https://github.com/shobhit-pathak/MatchZy/releases/latest/download/MatchZy-vX.X.X.zip -O matchzy.zip
unzip matchzy.zip -d /home/cs2/cs2-server/game/csgo/addons/counterstrikesharp/
chown -R cs2:cs2 /home/cs2/cs2-server/game/csgo/addons

# In-game console (or rcon):
css_plugins reload

Useful plugins to pair with MatchZy: CS2-SimpleAdmin (admin menu + bans), Retakes (4v4 retakes game mode), SharpTimer (surf/bhop timer), AntiRush (stop T rushing from spawn in warmup), PlayerSpeedometer (kz / surf quality of life).

09 // Workshop maps and custom map rotation

CS2 uses the Steam Workshop for custom maps. Unlike CS:GO, the server needs a Steam Web API key to fetch Workshop content:

1. Go to steamcommunity.com/dev/apikey, register a domain (any is fine), copy the key.
2. Pass it to the server with -authkey YOUR_WEB_API_KEY in start.sh.
3. Add maps by ID with +host_workshop_map 3070335208 (or whatever collection/map Workshop ID you want).

For a map collection (most community servers want this):

+host_workshop_collection 3070335208     // example collection ID

Find your Workshop map/collection IDs in the URL: steamcommunity.com/sharedfiles/filedetails/?id=3070335208.

Map rotation is controlled by mapcycle.txt inside game/csgo/cfg/, one map per line:

de_dust2
de_mirage
de_inferno
workshop/3070335208/de_cache_remastered
workshop/3070335208/de_season

10 // FastDL — get custom content to players instantly

The default in-game download from the server maxes out at 20 KB/s. For a 40 MB custom map, that’s a half-hour wait — players just disconnect.

FastDL solves this: a lightweight HTTP server hosts compressed copies of your maps/materials/sounds, and CS2 downloads them via HTTP at 10–100 MB/s instead of the game-protocol trickle.

Minimal server.cfg additions:

sv_downloadurl "https://fastdl.yourserver.com/csgo"
sv_allowdownload 1
sv_allowupload 0

But FastDL done badly causes more problems than it solves: wrong MIME types, missing bz2 compression, wrong folder structure, stale files. We wrote a full dedicated FastDL setup guide that covers the nginx config, bz2 compression, auto-sync cron script, and the permission traps that eat hours of debugging:

11 // SourceTV / GOTV — demos and spectators

SourceTV (branded “GOTV” in-game) lets spectators watch your server with a configurable delay, and auto-records every match to a .dem file. Essential for any competitive server — demos are how players review rounds and how you investigate cheat reports.

Minimum SourceTV cfg (already in the competitive example above):

tv_enable 1
tv_port 27020                   // UDP, must be open on firewall
tv_maxclients 10                // max simultaneous spectators
tv_delay 90                     // seconds — 90 is tournament standard
tv_autorecord 1                 // auto-save demos per match
tv_snapshotrate 64              // spectator tick rate
tv_title "My SourceTV"
tv_name "SourceTV"
tv_password ""                  // set if you want private spectators

Demos land in /home/cs2/cs2-server/game/csgo/ with filenames like auto-20260418-de_dust2.dem. Rotate them so you don’t fill the disk:

# Delete demos older than 14 days, weekly
(crontab -l; echo "0 5 * * 0 find /home/cs2/cs2-server/game/csgo -name 'auto-*.dem' -mtime +14 -delete") | crontab -

12 // Remote admin (RCON)

RCON lets you run console commands remotely — change map, kick players, reload cfgs — without being in the server. Three ways to use it:

• In-game console — type rcon_password YOUR_PASS, then prefix commands with rcon: rcon changelevel de_mirage.
• Web RCON client — use a browser tool like HostingBuff’s RCON web client (coming soon in our tools section).
• CLI tool — rcon-cli, a small Go binary that speaks the Source RCON protocol.

# Install rcon-cli on your laptop
wget https://github.com/gorcon/rcon-cli/releases/latest/download/rcon-linux_amd64.tar.gz
tar -xzf rcon-linux_amd64.tar.gz
sudo mv rcon /usr/local/bin/rcon-cli

# Use it
rcon-cli -a your.server.ip:27015 -p YOUR_RCON_PASSWORD "status"
rcon-cli -a your.server.ip:27015 -p YOUR_RCON_PASSWORD "changelevel de_mirage"

13 // Firewall and ports

CS2 uses UDP, not TCP. Open these ports inbound on your VPS:

Using ufw on Ubuntu:

sudo ufw allow 27015/udp
sudo ufw allow 27015/tcp      # only if you need remote rcon
sudo ufw allow 27020/udp      # only if SourceTV
sudo ufw allow 22/tcp         # keep SSH open!
sudo ufw enable
sudo ufw status numbered

14 // Troubleshooting — common CS2 server problems

15 // Self-hosted vs FaceIt / ESEA / managed panels

Why self-host CS2 instead of renting a slot on FaceIt / ESEA / a managed panel?

16 // Hosting recommendations

Based on the scenarios in section 01, here are the concrete Hostinger plans we recommend for CS2:

17 // Next steps

• FastDL — so players download custom maps in seconds, not minutes. FastDL Setup for CS2 & TF2 →
• Panel management — tired of SSH? Put CS2 behind a panel for easy starts/stops/log tailing. Pterodactyl setup →
• Windows alternative — same server stack on Windows with a GUI panel. WindowsGSM setup →
• TF2 server — same engine family, same tooling, different gameplay. TF2 community server guide →
• RCON web tool — upcoming in our tools section. Tools →
