map installation

[alknowshow]

im running source DS on windows
im running it on a pc which has a steam account but does not actually have half life 2. i want to run the server off this pc so i can play on it from my other pc.
i downloaded a pack of deathmatch maps and associated models etc, but how do i install them on the server pc so that when i launch a game i can choose which map to run, and if necesary upload it to players who need it?
any help much appreciated, thanks

put them in your moddir/maps folder, besure to edit maplist.txt and mapcycle.txt

also set allow_download to 1 in server.cfg

thing is, there's a maplist.txt and stuff for 3rd party mod's iv installed, but not actually for half life death match. is this because its effectively a mod that valve made? if so, can i install it without paying for another half life 2 licence?

you don't need to pay anything to run dedicated servers.each mod should have its own mapcycle.txt
