I need some help administering the server.

[NeedALotOfHelpXD]

Let's say i would try a lan server and play a capture the flag "coop" - humans vs bot.
And then i'd like to change and play team deathmatch.
And then change the order of the maps or the time limit.
What i'm doing now, and i hope it's the wrong way to do it, because there must be an "easyer-and-for-stupid-kids-way" is:
i have several server.cfg, i shut down the server, cp the one i want to use over the old, and restart the server.
Everyone reconnect and we play till we decide to use a new mutator/mode.
There must be an easyer way to do it, something like in openarena (mouse + gui + click = feeling dumb but everyone happy).
Also because if i'm sick my friends can't play lan games or prefer to play something easyer to configure. =P
Can someone point me to the following documentations? I need how to autenticate with the server from remote, (like in enemy territory quake wars, and how to give commands on the fly to the server).
Any help is greatly appreciated.

Since you have them in separate configs, put them all in the same directory, but with different names, then while in-game just do:

{l Code}: {l Select All Code}

exec name_of_config_file

It'll execute the config like it would when you start up the server. Though, unless I'm reading you wrong, why are you using multiple config files when you can change any variable in-game, and simply VOTE different matches?

Voting for something:
F2 -> choose a map/mode/mutator setting
F3 -> vote for chosen settings

To claim admin:
/setmaster [masterpassword] (change masterpassword for the one you have set in serverinit.cfg)
For example: /setmaster redeclipse

To force a gamemode and map as admin:
/mastermode 1
/[gamemode] [map]
For example: /deathmatch echo
