I also set up zones for compute nodes and server nodes (separate from management node). The servers are not supposed to have ssh between each other, the compute nodes shall communicate freely among themselves. So fine, so far it works. But: I also would like the server nodes to be able to SSH into the compute nodes. Simply put, I want the authorized_keys file on the compute nodes contain the key for root on the management node and the key from the server zone. Can this be achieved with the zone setup? Is there a file where one could pre-fill authorized_keys? My assumption is that one would need to hack around, with the best solution being an attribute in the zones table that says which zones, in addition to the management/service node(s), are allowed passwordless access. Of course that would need a bit more extensive hacking (and change in the database).
