Day of Infamy Open Configuration

The configuration of the Kim Jong Un Day of Infamy servers: the game and SourceMod settings of each game mode, the MOTDs, the scripts that install and update a server, and the systemd units that run and monitor it.

For players, docs/Clients.md covers the client settings the servers need.

Usage

Clone this repository into the doi/cfg folder of the server, as doi/cfg/doi-config. Source configs can't resolve paths dynamically, so the configuration only works at that location.

Then create a server.cfg that sets the server's name and runs one of the init-<config>.cfg files. For the Coop Commando configuration, for example:

hostname "MY-SERVER-NAME"
rcon_password "MY-PASSWORD"

exec doi-config/init-coop-commando.cfg

The workshop ID file of the configuration in the configs folder has to be passed to SRCDS on the command line with sv_workshop_list_file, as it can't be changed once the server is running.

prepare_server.sh

scripts/prepare_server.sh sets up or updates a server before it starts:

scripts/prepare_server.sh <server folder> [<config>]

It installs or updates the game with SteamCMD, clones or pulls this repository into doi/cfg/doi-config, and installs the latest Metamod:Source and SourceMod together with the plugins the configuration uses (SourceBans++, Advertisements and their dependencies). It then links the mods, game mode configs and plugins of this repository into the server and compiles the plugins. AFK Manager, which is no longer maintained upstream, is kept in this repository's sourcemod folder.

<config> names one of the server configs in the texts folder, e.g. coop-commando for texts/server_coop-commando.cfg. That config becomes the server's server.cfg, and the matching texts/motd_<config>.txt its MOTD. The SERVER_CONFIG_NAME environment variable can name the config instead. Without either, the server needs a server.cfg of its own, as described above.

If the RCON_PASSWORD environment variable is set, the script writes it to rcon.cfg and runs that from server.cfg.

Running with systemd

The systemd folder has user units for running the servers, one instance per config:

• doi-server@<config>.service runs the server in ~/servers/dayofinfamy-<config>, after running prepare_server.sh from this repository in ~/doi-config. Its ports, startup map, workshop ID file, theater and password come from ~/.config/systemd/user/doi-server@<config>.env (SERVER_PORT, TV_PORT, CLIENT_PORT, STARTUP_MAP, WORKSHOP_IDS_FILE, THEATER, SERVER_PASSWORD). The contents of ~/doi-secrets, like the database credentials of SourceMod and SourceBans++, are copied into the server's doi folder before it starts.
• doi-server-restart@<config>.timer restarts the server every day at 06:00, which also updates it.
• check_srcds_monitor@<config>.service queries the server every 30 seconds and restarts it once it stops answering. Its settings come from ~/.config/systemd/user/check_srcds_monitor@<config>.env, see monitor/check_srcds_monitor@coop-commando.env for an example.

Server notes

Engine hunk overflow

The configuration sets r_hunkalloclightmaps 0, which prevents crashes on large maps like ardennes. Community maps of that size contain a lot of lightmap data and otherwise crash the server with an Engine Hunk Overflow. In some cases, like when such a map is the server's startup map, the setting also has to be passed on the server's command line, as doi-server@.service does.

Libraries (Linux)

The game server needs the following 32-bit libraries on Linux:

glibc
libgcc
libstdc++
SDL2
zlib

SDL2 can be replaced with sdl2-compat, which implements SDL2 on top of SDL3. prepare_server.sh removes the outdated copies of libgcc, libstdc++, libogg and libvorbis that come with the game, so the system's libraries are used instead.

The Steam client library can load these libraries as well, but only in the game client, not in a server:

SDL3
libX11
PulseAudio (libpulse)

The game server binaries also reference these libraries:

OpenAL
util-linux
freetype2
fontconfig

Only the client code paths in engine.so load them, so if a server asks for any of them, something is wrong. This happened when an update removed BattlEye from the game in 2025, until a second update fixed it the next day.

Tickrate

Don't change the tickrate of Day of Infamy. The game can run at 128 tick, but never supported it properly: throwables like grenades start to bounce excessively, and the game's physics break down in general, even if everything else seems fine.

Difficulty scaler

The doi_difficulty_scaler SourceMod plugin adjusts the number of bots to the number of players, independently of the map's scripting. For this to work, the active game mode needs its server_<gamemode>.cfg from the configs/gamemodes folder, which prepare_server.sh links into the server.

Server patch

server-patch/server_srv.so is a modified game server library that enables stats with custom content and lifts the playlist restrictions. prepare_server.sh copies it into doi/bin.

GeoIP2 databases

SourceMod and the SourceBans++ web panel both use MaxMind's GeoIP2 databases. Both ship MMDB files, but those haven't been updated in years. Instead, install and configure geoipupdate, which needs a free MaxMind account and keeps current databases in /var/lib/GeoIP. prepare_server.sh and deploy_sourcebans.sh link the databases from there when they exist.
