Hi,

I am trying to install oracle 10g RAC on CentOS release 5.4 (Final), But when I am not able to configure SSH between oracle users on both node.

Node 1
--------
[oracle@node1 ~]$ id
uid=600(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)
[oracle@node1 ~]$ date
Thu Dec 30 05:14:10 IST 2010
[oracle@node1 ~]$
------------

Node2
----------
[oracle@node2 ~]$ id
uid=600(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)
[oracle@node2 ~]$ date
Thu Dec 30 05:15:32 IST 2010
[oracle@node2 ~]$

---------
OS
----------
[oracle@node2 .ssh]$ cat /etc/redhat-release
CentOS release 5.4 (Final)
[oracle@node2 .ssh]$ date

---------
Host for both node
--------
[oracle@node2 .ssh]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
# Public
10.1.1.10 node1
10.1.1.11 node2
#Private

20.1.1.11 node2-priv
#Virtual
10.1.1.21 node1-vip
10.1.1.22 node2-vip

------------------------
I am using the command to configure SSH provide in the link

This Quote:
I am not able to configure SSH between oracle users
is not a very good description of your problem. A little more detail, perhaps?

And in the meantime, what are the access modes on the directory $HOME/.ssh and all the files within it?

The file access modes (or "permissions" as some people put it) must be set correctly (to protect your private keys, for instance) or the ssh equivalence will not work. Use
ls -l
to display them. Your umask may be setting them incorrectly. Talk to your system administrator about it.

But you still haven't said what your problem is.
