How, exactly?

As which user? As usual, showing actual
commands with their actual output can be more
helpful than vague descriptions and
interpretations.

> [...] in RAC configuration [...]

Not a very detailed description of who tried
to do what.

@steven
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

hi

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
"dbadmin" user?

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
node(s)".

A Web search for
oracle INS-06006
led to some not-very-informative pages,
including one with the "ping" advice above,
and the official-looking:

http://download.oracle.com/docs/cd/E11882_01/server.112/e17766/framework_errormessages.htm

[...]
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.

Make sure you add a key for the same host. You don't need just a key for the other host RAC host, you need the key added to authorized_keys file in each host for itself as well.

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.
