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 LAM 7.0.6/MPI 2 C++/ROMIO - Indiana University n-1<3705> ssi:boot:base:linear: booting n0 (HOST) n-1<3705> ssi:boot:base:linear: booting n1 (indi.mshome.com) shwetank@indi.mshome.com's password: shwetank@indi.mshome.com's password: ERROR: LAM/MPI unexpectedly received the fo llowing on stderr: Permission denied, please try again. shwetank@indi.mshome.com's password: Permission denied, please try again. |
Doesn't sound like your passwordless authentication is working. Did you remember to copy the public key to all of the authorized_keys files on the nodes?
