[ Some special characters may be displayed incorrectly. ]
in the test you made I see the hostname in all lowercase, the error message
stated a different case. Can you try your interactive commands with GCMaster?
I'm not sure, how ssh will handle different spelling in the know_hosts file,
although they have the same TCP/IP address.
As long as you are using only serial jobs, there is no need for ssh or rsh
between the two machines at all. Also running parallel jobs can use the built-in
qrsh (if they are tightly integrated), and still there is no need for rsh/ssh.
Both machines are defined as adminstration hosts, and your one node also as exec
host and submit host?
