[Beowulf] ssh connection passwordless

I have a computing machine and a desktop ssh passwordless
interconnected through a Zyxel router (which is dhpc on Internet). I
have now added a second computing machine. I am unable to get all
three machines passwordless interconnected at the same time. Just only
two. If I want to have the third computer passwordless connected to
one of the other two, I have to exchange id_rsa.pub between the two
again. Mistake or intrinsic feature of ssh?
What I did:
(1)generating the keys with "ssh-keygen -t rsa"
(2) getting "reserved" the machines on the router
(3)scp id_rsa.pub to the "authorized_keys"
It is also mandatory that asking the "date" to the other computer
(slogin ... date), the date is given without asking the password. That
is an issue of a computational code that for its internal
parallelization needs that (I have not investigated why).
