Heyyo,
Hmm, so are you typing these into the dedicated server's console? or on your screen?
btw, for the ingame commands list, all the bot command's aren't recognized by the easy access console commands. Now, for E[POD]bot, you need to type stuff like:
pb addbot
pb kickbot
and so on. The DS bot commands are all listed in the readme's, so read into them.
Now, the console probably won't say that bot's are being added n' so on, so check the player list to see if they were added indeed.
If you wanna add bot's n' such from a computer that joined the server, you need to use rcon.
first, for the server, you need to set an rcon password. here's how:
rcon_password "epbrules"
now the password is "epbrules"
so for the client computer (the one that joined the server) you should just need to type: rcon_password "epbrules" again so that the client's set on that password, then you just do normal console commands I think, so stuff yet again like:
pb addbot
pb kickbot
if that doesn't work i think you need the rcon prefix, so:
rcon pb addbot
rcon pb kickbot
If these don't work.. well.. err... read the cs manual, it should say how to use rcon.
