Hi Alex,
If you want to connect from A to B then you generate your keys on A and add
it in the authorized_hosts in B.
If you want to connect also from X,Y,Z to B then you generate one pair of
keys per server (X,Y,Z) and append it to the authorized_hosts file in B.
This file can have as many public keys as hosts you need to connect from
(not sure if there's a limit but i doubt you'll reach it!).
Good luck,
David
