Currently we do not have any reasonable amount of rcon support. Server administration is best done as a player inside the server. These commands can be used inside the server by admins. The commands are not case sensitive, aside from the password used for adminlogin
Followed by the server's admin password, allows you to log into a server as an admin.
Logs out as admin
getinfo or whois
Gives a user's SteamID. This SteamID is in hexadecimal; if you want to convert it to a normal Base 10 number, I'd recommend you use the Windows calculator (put it in Programmer mode, click Hex, paste in the value, and click Dec). Most hexadecimal-to-decimal converters on the web can't handle the large values and will mess up at least the last two digits.

Pauses the server iff the server has admin pausing enabled
