Oracle now has an automated routine for trusted SSH setup ?? That is nice.......sometimes getting this right is a real pain with all sorts of subtle errors.

First, I don't suppose you're installing 11gR2 Clusterware? If you are, there's a "SSH Connectivity" button that you click, and Oracle will set everything up for you. Otherwise, check the log files. Anything in /var/log/secure? Try starting sshd in the foreground with the '-d' option to turn on debugging, and then attempt a login. Hope that helps, -Mark From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of John Smith Sent: Wednesday, April 07, 2010 7:07 PM To: oracle-l@xxxxxxxxxxxxx Subject: rac user equivalence Not precisely oracle, but related. Trying to set up user equivalence on redhat 5. When I ssh from node 2 to node 1, connecting as oracle, it works fine, no problems. But when I ssh from node 1 to node 2 as oracle, it immediately closes the connection after entering the password. This happens no matter what user id I connect from to the oracle account. I can ssh to other accounts on rac2, but not the oracle account. ssh_config and sshd_config are identical, as are hosts.allow and hosts.deny. Anyone have any ideas?
