I had configured passwordless ssh between two nodes for oracle RAC configuration and it works fine when i tried it manually by giving ssh command in both the nodes.But for the same nodes it gives the following error in RAC configuration
[INS-06006] Passwordless SSH connectivity not set up between the following node(s)

As which user? As usual, showing actual
commands with their actual output can be more
helpful than vague descriptions and
> [...] in RAC configuration [...]
Not a very detailed description of who tried
to do what.

Thanks for ur immediate response
for u steven and Vishnu
we are having two nodes in which we are planning to configure real application cluster of oracle for the same we need to configure a passwordless ssh.Ijust followed the usual steps for configuring passwordless ssh for a particular user called dbadmin and it works.But the same when i install grid infrastructure it is giving the error.For configuring ssh i had follwed the same steps given by vishnu in the above post.
INS-06006] Passwordless SSH connectivity not set up between the following node(s)
So what i should do for solving this

please check this note on https://support.oracle.com:
Common 11gR2 Grid Infrastructure runInstaller Error [ID 1056713.1]
P: [INS-06006] Passwordless SSH connectivity not set up between the following node(s): [node1, node2].
S: If OUI is able to setup passwordless SSH connectivity but still shows the error, likely "ping" command is inaccessible - grid user should be able to execute ping command
this answers all the ssh related questions.

Which "the usual steps"? Public-key
authorization? Host-based authorization?

What, exactly, does "it works" mean to you?
Is the Oracle program doing its work as this

Not being an Oracle user, I know nothing.
Among the things I don't know is exactly what
the program is doing (and as which user it's
doing it) when it emits that complaint. From
here, I can't even see "the following
A Web search for
led to some not-very-informative pages,
including one with the "ping" advice above,
and the official-looking:
INS-06006: Passwordless SSH connectivity not set up between the following node(s): string.
Cause: Either passwordless SSH connectivity is not setup between specified node(s) or
they are not reachable. Refer to the logs for more details.
Action: Refer to the logs for more details or contact Oracle Support Services.
Have you looked in "the logs"? That
"contact" advice seems reasonable.

Basically, come up with a single authorized_keys file which contains keys for ALL of the hosts in the cluster, and put this same authorized_keys file in all of the hosts. That way all hosts can talk to each other, all hosts can talk to themselves.
