How To Edit Half-Life Deathmatch: Source Server Config Files

Most settings on your Half-Life Deathmatch: Source server live in two files in the hl1mp folder. You can edit them in Files.

server.cfg

Location: hl1mp/cfg/server.cfg

The server runs this file when it starts and on every map change. Use it for rules like these, one per line:

CommandWhat it does
mp_timelimit 20Minutes per map.
mp_fraglimit 30Frags that end the map. 0 turns it off.
mp_teamplay 1Turns on team play.
mp_friendlyfire 1Lets teammates damage each other.
mp_falldamage 1Realistic fall damage.
mp_weaponstay 1Weapons respawn straight away.
mp_forcerespawn 0Players respawn when they choose.
sv_alltalk 1Everyone hears everyone on voice chat.

hostname, sv_password and rcon_password are set from your Settings page every time the server starts, so change them there.

mapcycle.txt

Location: hl1mp/mapcycle.txt

Your map rotation, one map per line. See change map.

Tip

To find a command, type find and a word in the server console, for example find gravity.
