lamboot problem in LAM/MPI
 

Hi friends
While executing the command lamboot -v hostfile(hostfile contains the list of hosts to which I want to connect),It requires authentication for different hosts.
After giving the password for a host.I get an error:
ERROR: LAM/MPI unexpectedly received the following on stderr:
Permission denied, please try again..
The command recon -v hostfile is executing perfactly,
but lamboot -v hostfile is troublesome.

we also generate the public/private key pair in /root/.ssh/
Plz anybody suggest me a solution.

This is all which is generating when i execute lamboot -v hostfile
