Edit the game server config of arma3server (not the headless client) arma3server.server.cfg and add the headless client IP address to headlessClients[]=. If the headless client is on the same physical server as the ARMA 3 server then also add the IP to localClient[]=.
edit Player.Arma3Profile and add the line battleyeLicense=1;.
Start your server with ./arma3server start
Start your headless client with ./arma3server-hc start.
Only an admin can see the headless clients in the player menu on the server. The headless client will connect and automatically assume the first available headless client slot.
Mod Support
Adding Mods
Mods can cause your server to become unstable or may not be compatible with each other. It is a good idea to read the mods docs and/or speak with other experienced Arma3 admins.
Here is a popular mod to get started:
Create a directory called @cba_a3 in serverfiles/mods
serverfiles/mods/@cba_a3
Copy the contents of the mod archive to the @cba_a3 directory.
Remember to check you have the correct user permissions once uploaded
Copy the contents of the @cba_a3/keys directory to the server keys directory.
If you are adding multiple mods make sure you put a semicolon with the escape character in between each mod.
mods="mods/@mod1\;mods/@mod2"
Lower Case File Names
Arma 3 server requires that mods have lowercase names. Some mods do not do this and will need to have their file names converted to lowercase.
This can be done by using the following script.
Run the script from the serverfiles/mods directory.
#!/bin/bash
depth=0
for x in $(find . -type d | sed "s/[^/]//g")
do
if [ ${depth} -lt ${#x} ]
then
let depth=${#x}
fi
done
echo "the depth is ${depth}"
for ((i=1;i<=${depth};i++))
do
for x in $(find . -maxdepth $i | grep [A-Z])
do
mv $x $(echo $x | tr 'A-Z' 'a-z')
done
done
