Did you try compute -> master?

I am assuming the master has two (or more) interfaces and that the
hostname is based on the external interface. I am also assuming that
the computer nodes are only connected to the master's internal
interface. The master's internal interface has either (1) no name or
(2) a different name that the computes should be using instead. If
this is the case, either set a separate name for the internal
interface or just use IP addresses.
