Hi,
I finally managed to install the clients of my cluster, and now I am having
problems with the final step: the root can't connect to the clients by ssh.

The wizard's log is this:

=============================================================================
== oscar_wizard: Starting...
=============================================================================


=============================================================================
== Running step 7 of the OSCAR wizard: Complete cluster setup
=============================================================================

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-with-mic,password).
Improper count (0) returned from machine oscarnode1.linuxcluster at

more info at /usr/bin/post_install line 93

=============================================================================
== oscar_wizard: Exit
=============================================================================


The log don't show, but the prompt show the follow message:

warning: the RSA host key for 'oscarnode1.linuxcluster' differs from
the IPaddress '192.168.0.2'
Offending key for IP in /rot/.ssh/know_hosts:1

Are you sure you want to connect (yes/no)?

If I reply 'yes' the prompt ask me for password for
r...@oscarnode1.linuxcluster, but I don't have it.

My .ssh/know_hosts file contains something like that

oscarnode1, 129.168.0.2, (and a key)
oscarnode2, 192.168.0.3, (and a key)


Someone have any idea about what is happening here?
