Ugh, it's 9:15pm, and I'm just now heading home, so, brain is a bit fried.

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,

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 

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?

[root@rac2 ssh]# ssh oracle@rac1
oracle@rac1's password:
Last login: Wed Apr  7 15:48:24 2010 from rac2
[oracle@rac1 ~]$

[oracle@rac1 ~]$ ssh oracle@rac2
oracle@rac2's password:

[root@rac1 ~]$ ssh oracle@rac2
