ssh authentication failures

[mixxalot@yahoo.com]

I am setting up a test Oracle 11gR1 RAC cluster on RHEL 5 server. The problem that I am having is related to ssh equivalency. I able to perform the initial key generation for ssh on the first RAC node of the two node test cluster. However, when I try to scp over the keys to the second RAC node, it fails with
the error message "Too many authentication failures for oracle lost connection"

$ scp authorized_keys iss-365-rac02:/u01/app/oracle/.ssh/
The authenticity of host 'iss-365-rac02 (64.147.176.16' can't be established.
RSA key fingerprint is d5:2d:88:77:40:22:70:14:b9:96:de:53:35:76:c6:96.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'iss-365-rac02,64.147.176.168' (RSA) to the list of known hosts.

Received disconnect from 64.147.176.168: 2: Too many authentication failures for oracle
lost connection
oracle@iss-365-rac01 .ssh$

Has anyone run into this problem before when setting up ssh between cluster nodes for RAC? And if so, how would you fix it?

Thanks!
Ben

On the machine to which you are trying to ssh, as root, use the following command to check your failure logs:
> faillog

This should show all failures for all usernames (if any)

You can reset it with the command:
> faillog -r
