i don't know exactly what you mean with passing from machine a to a. But you can just use:
rbds addbot
again.
If you want to pass commands from server A to B you need to setup rcon. You need to set up rcon and the rcon_password. Then let the other machine have the same rcon_password and you should be able to do this:
rcon rbds addbot
