After you have enter the RCON password you can access all the RCON capabilities, by typing:
/rcon [command]
RCON Commands

These commands allow individuals to remotely administer a server. Their use is based on having the RCON password. These commands are to be used in the console.
Kicking

There are two ways to do this. The first is to kick them using their player name:
/rcon kick [playername]

The second is to use their user number on the server:
/rcon status (this is to get a list of players and their user numbers)
/rcon clientkick [usernumber]
Restart Server

While you can't actually restart the server, you can reload the server.cfg, which amounts to about the same thing.
/rcon exec server.cfg
Ban an IP

The first thing that you have to do before banning anyone is to add this line to the server.cfg file:
set filterBan 1

Now you can add an IP to the ban list by typing at the console:
/rcon addIP [ip_address] (you can also use IP masks)

To remove an IP from the list:
/rcon removeIP [ip_address]

To list the IPs currently banned use the banlist.txt file.
Referees

Referees are a feature that has been added to help server admins manage their servers. The referee is like a less powerful version of RCON: you can set a password and give it out to trusted players. Unlike RCON, the referee has limited control over how they can affect the server. It gives them the ability to do things like mute annoying players, kick them and even ban them from the server for up to 3 hours. All referee commands start with the ref command. The basic referee command looks something like this:
ref {refcommand} [{parameters} ...]

Referee commands can only be used by a client who has logged on as a referee using the reflogin command with a valid password. If a password has not been set, or if the server has disabled the referee function, no one will be able to login as a referee.
Enabling Referees

To enable a referee, a server admin first needs to set the referee password:
/g_refpass "password"

Then set whether the referee can ban people:
/g_refNoBan 0 (to give them ban power)
/g_refNoBan 1 (to stop them from banning players)

Finally enable referees:
/g_referee 1

Be very careful with allowing referees to ban players on your server, unless you can trust them to use the power responsibly. Otherwise, you might find angry players boycotting your server!
Log on as Referee

To login as a referee you need to ask the server administrator for the referee password. Once you have it, you can login by pulling down the Quake III console and typing:
/reflogin "password"

If you enter the password correctly and the server is set up to allow referees, then you will receive a message telling you that you have successfully logged in. Once logged in you can use all the referee commands. These commands and their effects are listed below.

!command [] description
Time Suffixes

Commands that deal with time duration like !tempban can use time suffixes.

m = minutes

d = days

h = hours

w = weeks

Example:

1d = 1 day

3h = 3 hours

Player Identification

Commands that accept player designations can use several inputs.
Partial Name

The simplest player identifier is the players name. You can use any part of the player name. Only enough charachters to match the players name uniquely is needed. If more than one player on the server has a simular name, you will be prompted with all players matching that name and thier client id.

Example:

!warn playe cuss

This will first search for players with “playe” in thier name; including “player”, “unkownplayer”, and “played”. If more that one player is found a list of results will be shown to pick a more specific user.

Tip:
You can use the !find to show what players match a given name.
Client ID

The client ID is the number assigned to the player by the game itself. The client ID only works for the current gaming session. For a list of players’ client IDs, use the !list command. If a players name is too hard to type or there are more than one players with simuilar names, you can use the client id to single them out.

Example:

!kick 3 tk

Database ID

The Database ID is the players unique identification within the B3 database. It is prepended with an “@” and is often referred to as the “at ID”. This ID is displayed with the !* Leveltest command and the !lookup command. You can use this ID to perform actions against a player even when that player is not connected.

Example:

!makereg @1235

Tip:
You can use the !lookup command to find offline users in the database.
