This guide will show you how to set up your own Half-Life 2 Deathmatch server on a Linode running Debian or Ubuntu. Hl2 is a multiplayer, first-person shooter video game.

Before You Begin

  1. Complete our Install SteamCMD for a Steam Game Server guide.

  2. This guide is written for a non-root user. Commands that require elevated privileges are prefixed with sudo. If you’re not familiar with the sudo command, see the Users and Groups guide.

  3. Add two firewall rules to extend the port range available to the server. This command assumes that you have only the iptables rules in place from the SteamCMD guide. If not, find the corresponding lines and replace the numbers in INPUT 5 and INPUT 7 below:

    sudo iptables -R INPUT 5 -p udp -m udp --sport 27000:27030 --dport 1025:65355 -j ACCEPT
sudo iptables -I INPUT 7 -p udp -m udp --dport 27000:27030 -j ACCEPT

Install Server Using SteamCMD

  1. Execute steamcmd:

    steamcmd

  2. Login as anonymous:

    login anonymous

  3. Download the server:

    app_update 232370 validate

  4. Exit from SteamCMD:

    quit

Occasionally, SteamCMD encounters an unreported error, but completes successfully. If the steps in the Run the Server section are not successful, repeat the installation process to retrieve all of the game data, then run the server again.

Run the Steam Server

  1. cd into the server folder:

    cd .steam/SteamApps/common/Half-Life\ 2\ Deathmatch\ Dedicated\ Server/

  2. Run the server:

    ./srcds_run -game hl2mp +sv_password MyLinode +mp_teamplay 1 +maxplayers 8 +map dm_runoff

    In the above command:

    • game: The game’s files directory. This is the only parameter you can’t write in server.cfg because it specifies the game folder, where the server.cfg file itself is.

    • sv_password: Password required to enter your server. If this parameter is not set, the server is accessible without a password.

    • mp_teamplay: Specifies whether the game mode is team deathmatch or deathmatch.

    • maxplayers: Maximum number of simultaneous players allowed on the server. Half-Life 2: Deathmatch officially supports a maximum of 16 players.

    • map: The map with which to start the server. Write the name of the map file without the .bsp extension.

      For more parameter options, visit the Valve Wiki.

Stop the Server

To stop the server, hold the CTRL key on your keyboard and press C (CTRL+C). The output will resemble:

Thu Jul 25 04:06:48 CEST 2017: Server Quit

Forcibly killing the server shouldn’t be harmful, but it can cause data corruption if you have plug-ins which write to a database.

Run the Server Within a Screen Socket

To keep the server running in the background, execute it using Screen:

screen ./srcds_run -game hl2mp +sv_password MyLinode +mp_teamplay 1 +maxplayers 8 +map dm_runoff

To exit the screen:

exit

For more information on Screen sockets, visit our guide on Screen.

Autostart with a Screen Script

This script automatically starts your server in a Screen session.

  1. Create the script:

    File: ~/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server/run.sh

    #!/bin/sh
cd "$HOME/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server"
screen -S "HL2DM" -d -m
screen -r "HL2DM" -X stuff "./srcds_run -game hl2mp +sv_password MyLinode +mp_teamplay 1 +maxplayers 8 +map dm_runoff\n"

  2. Mark the file as executable:

    chmod +x run.sh

  3. Run the script:

    ./run.sh

Configure the Half-Life 2 Server

The server.cfg file contains the settings of your server. It is not present by default because you can start the server using the parameters from the command line.

Note that if server.cfg is present, its settings override any parameters that are set when you start the server through the command line.

Below is a sample server configuration:

Custom Half-Life 2 Maps

There are eight (8) official maps in Half-Life 2: Deathmatch. A preview of each map is available on Combine OverWiki’s official page:

  • dm_lockdown
  • dm_overwatch
  • dm_powerhouse
  • dm_resistance
  • dm_runoff
  • dm_steamlab
  • dm_underpass
  • halls3

Half-Life 2 Deathmatch requires that custom maps be in specific locations based on their type:

  • VPK: ~/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server/hl2mp/custom

  • BSP: ~/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server/hl2mp/custom/maps

The resources-upload system is enabled by default, and any player who doesn’t have the selected map will automatically download it and any required extra content from your server. Check GAMEBANANA for additional custom maps.

Maps Rotation

When a match ends, the server starts a new match with the next map in the rotation list.

If mapcycle.txt is not available, the system uses the default map rotation list in mapcycle_default.txt.

File: ~/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server/hl2mp/cfg/mapcycle_default.txt

// Default mapcycle file for hl2mp
//
// DO NOT MODIFY THIS FILE!
// Instead, copy it to mapcycle.txt and modify that file.  If no custom mapcycle.txt file is found,
// this file will be used as the default.
//
// Also, note that the "mapcyclefile" convar can be used to specify a particular mapcycle file.

dm_lockdown
dm_overwatch
dm_powerhouse
dm_resistance
dm_runoff
dm_steamlab
dm_underpass

To add a custom map to the rotation:

  1. Copy mapcycle_default.txt to mapcycle.txt:

    cp hl2mp/cfg/mapcycle_default.txt hl2mp/cfg/mapcycle.txt

  2. Write the custom map’s name inside mapcycle.txt. For example: if you have the map dm_custom.bsp:

File: ~/.steam/SteamApps/common/Half-Life 2 Deathmatch Dedicated Server/hl2mp/cfg/mapcycle.txt
// Default mapcycle file for hl2mp
//
// DO NOT MODIFY THIS FILE!
// Instead, copy it to mapcycle.txt and modify that file.  If no custom mapcycle.txt file is found,
// this file will be used as the default.
//
// Also, note that the "mapcyclefile" convar can be used to specify a particular mapcycle file.

dm_custom // Your custom map
dm_lockdown
dm_overwatch
dm_powerhouse
dm_resistance
dm_runoff
dm_steamlab
dm_underpass
