Jeremy and All,
here's the solution for adding submit hosts outside of the OSCAR cluster proper:
1. Add the submit hosts to the /etc/hosts.equiv file on the pbs server.
2. qmgr -c "s s acl_host_enable=true"
3. qmgr -c "s s acl_hosts=<hostname1>,<hostname2>"
The acl_hosts list as well as the /etc/hosts.equiv file also takes wildcards. This is working for me since Sunday ....
Thanks to everyone who took the time to help me out with this.
regards,
Mike
PS: This should be in the FAQ's .... How do I submit it ?

Sorry Mike-
I've been on vacation, and I've been unable to catch my breath yet in a flood of mail. You won't believe this, but I think a hosts.equiv file is needed on the server machine w/ names of submit machines.... I'll dig for some details on it.

All,
thanks to Wendy, I made some progress:
qmgr -c "set acl_host_enable=1"
qmgr -c "set acl_hosts=*.oscar"
*.oscar is my private subnet. Some of those nodes are meant to be submit nodes.
Anyway, I still cannot submit a job from anywhere else but the head node, and I have
the following snipppet out of the server log:

Where does the PBS server store its ACL files ?

Mike
