After adding yourself as owner you can use the following commands:
moderatorid STEAMID
This command is used to give someone access to the admin commands.
kick NAME
This will kick someone from the server. You don't need the full name, unique partials will work. This also broadcasts a KICKED message to the server.
ban
This will execute a kick ban. It will thusly be broadcasted to the entire server.
banid STEAMID
This command will ban a user given their steamid. This is the only administrative punishment that does not broadcast to the rest of the server.
status
This will cause the console to print out a list of connected clients along with their ping, ip and steamid. This can be quite taxing if used on a fully populated server.
server.writecfg
This is a helpful command to force the server to write all bans / moderator id's which have been set to config files (located in the /server/*identity*/cfg folder. The config files do write upon shutdown, however if the server crashes... that will be lost. Therefore, it is smart to run this command after every ban to make sure it sticks.
inventory.give ITEM AMOUNT (example: inventory.give wood 1000)
This command allows you to give items to yourself. Note: the item name needs to be in the short name form (like rifle_bolt or metal_ore). To see all short names, check out the admin inventory site.
say "I am server console"
This allows you to speak as SERVER CONSOLE. Note, you need the quotes in to say multiple words.
server.globalchat 0
This will make text chat local (meaning only people close to each other can see each others chat messages). This is currently set to 1 by default.
env.time 0 - 24
Change the time on the server. 12 = noon.
teleport.toplayer
Just kidding! This ain't in yet... although, if I'm being honest, I'm ok with that. Fresh spawns asking to get a TP to their friends gets old real quick. However if you aren't aware there is a pseudo-teleport you can use to get around the map. See below for instructions
No clip
Admins can turn on no clip with right SHIFT-L.
Free cam
Right SHIFT-P turns on free cam. Note: This mode kinda sucks at the moment. People / buildings outside your characters render distance are not visible. Also, it's pretty damn slow moving.
vis.attack
This is a useful tool that will hopefully help pinpoint aimbots. It will enable a yellow trail behind every projectile. Be careful though this can become very taxing very quickly. In addition, if you enable this on your server you will see little metrics boxes pop up in game.
