Counter-Strike 2 (CS2) Modded Dedicated Server
If you are looking for the CS:GO version you can still access that here.
Every time you want to boot the server, you should run gcp.sh (if on Google Cloud) or install.sh (on Linux) and it will ensure your OS is up to date, CS2 is up to date, and pull down the latest patches from this mod (any updates that I push up).
Obviously, any changes you have made to the files in this mod will be overwritten so I have created a "custom files" folder where you mirror the contents of the game/csgo/ folder, and any files you want to tweak, you put in there in the same spot and they will always overwrite the mods default files. Read more about it here.
Attempts to implement a .NET Core scripting layer on top of a Metamod Source Plugin, allowing developers to create plugins that interact with the game server in a modern language (C#)
SharpTimer is a simple Surf/KZ/Bhop/MG/Deathrun/etc CS2 Timer plugin
Custom files
Note
Any reference to a path is always the root of the installation. Which on Linux will typically be /home/steam/cs2/ and on Windows where ever you extracted the zip.
For example on Linux:
/custom_files/addons/counterstrikesharp/configs/admins.json full path is /home/steam/cs2/custom_files/addons/counterstrikesharp/configs/admins.json/game/csgo/addons/counterstrikesharp/configs/admins.json full path is /home/steam/cs2/game/csgo/addons/counterstrikesharp/configs/admins.json
Any changes you have made to the files in this mod will be overwritten when the update scripts are ran. I have created a folder /custom_files/ in the root of the project, where you mirror the contents of the csgo/ folder, and any files you want to tweak, you put in there in the same spot and they will always overwrite the mods default files.
So this can be used to set the server hostname to something you want, set the RCON or serverpassword or set the admins of the server.
You can see an example of what I use on my server in the /custom_files_example/ directory, which sets the hostname, server image and admins.
For example; if you want to add yourself as an admin, that file is located /game/csgo/addons/counterstrikesharp/configs/admins.json. So to make your tweak to it, you would copy that file to /custom_files/addons/counterstrikesharp/configs/admins.json and add yourself as an admin at the bottom. Then when the update scripts run, it will copy your custom file at /custom_files/addons/counterstrikesharp/configs/admins.json and overwrite the default mod file at /game/csgo/addons/counterstrikesharp/configs/admins.json.
If you want to change the server name, or make any changes to any mod settings use the /cfg/custom_MOD.cfg as it executes at the end and can overwrite any setting. So if you wanted to change the server name for GunGame, you would copy /game/csgo/cfg/custom_dm.cfg to /custom_files/cfg/custom_dm.cfg and and write hostname "shipREKT GunGame +Deathmatch +Turbo" and any other settings you want and this file will overwrite /game/csgo/cfg/custom_dm.cfg each time the gcp.sh/install.sh/win.bat script is ran, and these settings will run at the end when you load the GunGame mod.
To generate this directory, you can run the gcp.sh script (if on Google Cloud), install.sh script on Linux once or on win.bat script on Windows where you extracted the mod zip and this is where you would put your custom modifications.
Creating an online server
If you are hosting an online server, you need to create a Steam Game Login Token, your server will not run online without this. Put this value in the STEAM_ACCOUNT environment variable or create a custom file for /game/csgo/cfg/secrets.cfg following the custom files steps (/custom_files/cfg/secrets.cfg) and set it in sv_setsteamaccount.
You also need to create an authorization key which will allow your server to download maps from the workshop. Put this value in the API_KEY environment variable.
You must connect to the server from the public IP, not the LAN IP even if you are on the same network. The script logs the public IP Starting server on XXX.XXX.XXX.XXX:27015
Creating a LAN server
Create a custom file for /game/csgo/cfg/env.cfg following the custom files steps (/custom_files/cfg/env.cfg) and set sv_lan to 1, sv_downloadurl to "" and sv_allowdownload to 1.
Environment variables
Available via environment variable only

Playing workshop maps/collections
To download maps from the workshop, your server needs access to the steam web api. To allow this you'll need an authorization key which you can generate here and set API_KEY to the key.
The console command for hosting a workshop collection is host_workshop_collection collectionid where collectionid is the number that comes after ?id= in the workshop URL for example: https://steamcommunity.com/sharedfiles/filedetails/?id=1092904694. This command will then download all maps in the collection and create a mapgroup out of them, then host it.
Setting maps for different game modes
Copy the file /game/csgo/gamemodes_server.txt following the custom files steps (/custom_files/gamemodes_server.txt) and add the maps you want per gamemode. Most gamemodes fall under casual, but I have created unique groups for each mode so adding your own maps is easy by updating this one file.
On local:
gcloud config set project <project>
cd /path/to/folder
gcloud compute scp de_kus.vpk root@<instance-name>:/home/steam/cs2/game/csgo/maps --zone australia-southeast1-c
On server SSH:
cd /home/steam/cs2/game/csgo/maps
chown steam:steam de_kus.vpk
chmod 644 de_kus.vpk
Make sure you port forward on your router TCP: 27015 and UDP: 27015 & 27020 so players can connect from the internet.
You must connect to the server from the public IP, not the LAN IP even if you are on the same network. The script logs the public IP Starting server on XXX.XXX.XXX.XXX:27015
Download this repo and extract it to where you want your server (i.e. C:\Server\cs2-modded-server). All the following instructions will use this as the root.
Edit \game\csgo\gameinfo.gi and search for Game_LowViolence csgo_lv it should be under GameInfo > FileSystem > SearchPaths and below it add Game csgo/addons/metamod and save the file. You can find detailed instructions here.
Create a folder steamcmd and download SteamCMD and extract it inside steamcmd so you should have \steamcmd\steamcmd.exe.
Accept both Private and Public connections on Windows Firewall.
If running for the first time
Once the CS2 server has started close it
If you want to use my bundled maps and this server setup you can use https://raw.githubusercontent.com/kus/cs2-modded-server-assets/master/game/csgo for your your sv_downloadurl in cfg/env.cfg. Make sure you change sv_allowdownload to 0.
Run win.bat again
To check everything is working correctly run the following commands in the server console:
meta list and you should see CounterStrikeSharp in the output
css_plugins list and you should see a few plugins in the output
If you see content in both; everything is working.
If you copy custom_bots.cfg and put it in the custom_files/cfg/ directory (/home/steam/cs2/custom_files/cfg/ on default Linux setup) and you can modify it and change say bot_quota to 10 if you want 10 players at all times. When the server starts (on Linux and Windows) it will merge this file into the game cfg and it will execute every time bots.cfg executes.
You can also just login to RCON rcon_password yourpassword and use rcon bot_add_ct and rcon bot_add_t.
If you want to remove bots you use rcon bot_kick.
Failed to open libtier0.so
Failed to open libtier0.so (/home/steam/cs2/bin/libgcc_s.so.1: version 'GCC_7.0.0' not found (required by /lib/i386-linux-gnu/libstdc++.so.6))
This is because Valve ships their own copies of those libraries. As modern systems will have newer versions, you can safely delete the listed file from the server install. Do not delete the file in the system path (usually lib or lib32)*.
cd /home/steam/cs2/bin/ and rm libgcc_s.so.1 and restart the server.
How do I connect to RCON remotely?
Download SourceAdminTool (source) for your OS (you can read about it here) and click Servers > Add Servers and put in the <IP>:27015 and when you see the server show in the list, down the bottom left type in your RCON password and click Login and you should be able to execute commands from the bottom text box i.e. exec dm.cfg
You must connect to the server from the public IP if hosting an online server, not the LAN IP even if you are on the same network. The script logs the public IP Starting server on XXX.XXX.XXX.XXX:27015
Why can't I set the server to start automatically with a mod loaded
Because the way the server is setup with several mods it's not possible. You can't use +exec in the server launcher as that executes to quick before SourceMod is loaded. You can monitor the server once it's started (via RCON) and then load a mod i.e. exec dm.cfg.
Acessing admin menu
Admins are managed by CounterStrikeSharp using the Admin Framework. You define admins and their flags and most plugins now utilise this framework.
Tests players with different traps, kz, surf, bhop
!rcon exec dm
Deathmatch
!rcon exec hns
Hide n Seek
!rcon exec kz
Kreedz Climbing
!rcon exec minigames
Mini Games
!rcon exec prac
Practice (grenade lineups etc)
!rcon exec scoutzknivez
ScoutzKnivez
!rcon exec soccer
Soccer
!rcon exec surf
Surf
!rcon exec wingman
Wingman (allows more than 4 players)
Changing between gamemodes multiple times is not recommended, and it is better if you restart the CS2 server in-between.
To view what other commands are available view the plugins at the top of the page.
RCON doesn't work
Using RCON whilst connected to the server does not work. See discussion here.
The current work arounds are:
I have included CS2Rcon which allows admins to use !rcon in chat.
You can disconnect from the server and use rcon_address IP:PORT in console and you can use rcon commands.
Use an external RCON program which has implemented the RCON protocol such as this.
If it still doesn't work, make sure you try connect from CS2 outside of a game via console:
You must connect to the server from the public IP if hosting an online server, not the LAN IP even if you are on the same network. The script logs the public IP Starting server on XXX.XXX.XXX.XXX:27015
rcon_address ip:port
rcon_password "password"
rcon say "hi"
And check the ports cs2 is using on your OS i.e. on Ubuntu sudo lsof -i -P -n | head -n 1; sudo lsof -i -P -n | grep cs2.
