SSH problem while installing Oracle grid software

Hi Experts,

I stuck while installing Oracle 12c grid software on oracle Linux 6. Actually I configured SSH on both nodes. Node2 keep asking password.

RAC01

$ ssh rac01 date

return date

$ ssh rac02 date

return date

-------------------------------------------------------------------------

RAC02

$ ssh rac01 date

password *********

$ssh rac02 date

return date
