I have managed to create a online dedicated server by:
Coping this folder C:\Program Files\Steam\SteamApps\'my name'\half-life 2 deathmatch\sourceforts
To here C:\Program Files\Steam\SteamApps\'my name'\source dedicated server\sourceforts
I then used two commands in server.cfg
sv_lan 0
heartbeat 1
Got the server running and people could access it over internet (GREAT SUCCESS-BORAT)
Now i wanted to get a plugin.. went to mani_admin_plugin and downloaded V1.1
I copied the mani files into this folder C:\Program Files\Steam\SteamApps\'my name'\source dedicated server\sourceforts (correct?)
Added my steam id to bottom of the admin list...
And added exec mani_server.cfg to my server.cfg
I then created a dedicated server... BUT neither ma_rcon or admin worked in either the external (dedicated server) console or the internal (sourceforts console) when im connect to my own dedicated server...
They just say unknown command or something similar (can't remember).
Please can someone help me I have been trying to get this to work for some time now...
