A thought...

If you are running realbot on a dedicated server, then you will not be able to use the 'h' key menu to do stuff with the bots on the server. You must run a 'listen server' (start Counter-Strike and then start a new game) to be able to add and remove bots.

If you setup RB for a dedicated server, I would recommend that you rather set it up for a listen server, and once it is working, copy the setup across to the dedicated server. Then, to add or remove bots, you will have to type in the relevant commands in the serve console.
