[torqueusers] cluster network configuration

I am experiencing a problem with my torque server and client
connection. My server has an ethernet interface on the public network that
is the named server in my torque config. There is a second network
interface that is a private network to the cluster on a 10.0.10 network,
with a hostname of admin. The compute nodes are only connected to the
private network, however the named server in both the head node and the
compute nodes is the public interface hostname. A pbsnodes command shows
all nodes as down. The log file on the server shows this error:
bad attempt to connect from 18.104.22.168:1022 (address not trusted - check
entry in server_priv/nodes)
That address is the public address of the server.
I am wondering if I should name the server admin? The only compute nodes
that the server will need to access are on the private network. What is
the standard way of setting up a single cluster environment?
I am able to ping the compute nodes from the head node and ssh with no
authentication. From the compute nodes I am able to ping the head node as
well, using the public or private network hostname, and I am able to ssh
either to the "wings" interface or the "admin" interface without
authentication. It seems like the communication lines are open. Any
suggestions would be welcome.
Thanks in advance,
