I myself did not purchase this game due to the previous releases being crap. but seen people asking about
rcon commands and I found some info on them so here you go.
/login - To login to Rcon
/logout - To logout of Rcon
/kickclient [player id] - This will kick a player according to its ID (given with the /status command).
/kick [player name] - This will do the same as the /clientkick command, but this command requires the player's name.
However, some names are very difficult to enter (with colour codes etc.), thats why the /clientkick commands is easier in use.
You can use 'all' as player name, this will kick all players from the server.
/drop - unknown
/dropclient - unknown
/tempBanClient [player id] - This will temporary ban a player using the player's ID. The length of a temporary ban can be changed in the server configuration file.
/tempBan [player name] - This will temporary ban a player using the player's name.
/ban [player name] - This command does the same as the /banclient command.
/banClient [player id] - This command will ban a player according to its ID. The player's GUID will be added to ban.txt.
However, this requires you to fill in the player's name, it is therefore advised to use the /banclient command (names can be long or contain colour codes).
/unban [player name] - This will unban a user according to the player's name.
/gameopt - Rcon command specific to MW3, can be used to set variables from Recipe
/serverinfo - This command shows the server settings and configurations.
/status - This shows information about the connected players. This includes the client ID, score, ping, GUID, name and IP address. The ID and name can be used for the following commands.
/dumpuser [player name] - This will give information about the player.
/map_restart - This will restart the current map.
/fast_restart - This will restart the current map just like /map_restart but is much faster as it will not load the map again. It will just restart the map.
/map [map name] - This will load the given map.
/killserver - As the name says, it will shut your server down.
/map_rotate - This will load the next map of the rotation. This is set in the 'sv_maprotation' file on your server.
/set - This command can se used to set variables, like: set <variable> <value>
It is very likely that you are not playing at the same location (IP address) as your server is. Thats where we use RCON (= remote control) commands for.
Using RCON is very easy, just add '/rcon ' in front of the commands above (removing the '/' of those commands). But before you can use RCON, you will have to login:
/rcon login <password> - Fill in the password of the server and you can use RCON commands.
Examples of RCON commands:
/rcon map mp_paris
/rcon banclient 5
