TORQUE can't prevent ssh/rsh logins, because those are out of its
control.  If you are using an OS with PAM, you can do some fun things
there.  See src/pam/README.pam or contrib/README.pam_authuser for a first

Job routing occurs based on resource requests and ACLs, not based on
other job attributes.

Others have argued for routing based on interactive or batch, but I
still maintain that it is a bad idea.

I don't see any misconfigs here.  Maui doesn't know anything about job
routing in TORQUE.
