hi
sometime the tricks just keep it simple
e.g.
in rocks the login node will have name like login-0-0 and login-0-1 etc
one can setup public interface the name also as login-0-0 and login-0-1
etc the FQDN will pick up from the subnet=public
This way the short name just login-0-0 for private and public net
SGE seems fine with this approach
I just setup ge2011.11p1 in a rocks cluster 6.0 without any
host_aliases file
both version of SGE will run (sge6.2u5p3 and ge2011.11p1)
of course to access which version of SGE you need to source the correct
version of settings.sh
regards

Hello.
I have a cluster running Rocks 5.4.3 that I originally setup with
Torque/Maui. I am testing Open Grid Scheduler using the
ge2011.11.tar distribution.
I setup OGE on the master head node and was able to also setup 6
compute nodes using "start_gui_installer" on the head node. All 6
compute nodes were setup without any issues.
All works except that when I tried to setup our login node, I
cannot. The login node has both a private & public network
interfaces. I want to setup our login node "login-node.xxx.uci.edu"
as an Executable and Submit node.
When I try to setup our Rocks login node using the private name of
login-1-1, it complains with:
The error message was:
error: commlib error: access denied (client IP resolved to host
name "login-1-1.local". This is not identical to clients host name
"login-node.xxx.uci.edu")
ERROR: unable to contact qmaster using port 6444 on host
"headnode.local"
So then I try installing OGE using the public name of
"login-node.xxx.uci.edu" and it also complains. As soon as I enter
"login-node.xxx.uci.edu" the state column turns red with "Resolvable"
and the "Install" GUI button is greyed out so I cannot continue.
Looks like OGE is confused about the actual fully qualified name of
our login node. The FQN is "login-node.xxx.uci.edu" but neither name
seems to work.
What is the correct why to get around this?
