To setup public key authentication method follow thefollowing steps:
1. Public key generation
local> ssh-keygen -t dsa -f .ssh/id_dsa
When a password is asked, leave it just pressing
Two new files id_dsa and id_dsa.pub are created in .ssh directory. The last one is a public part.
2. Public key distribution to remote nodes
Go to the .ssh directory. Copy the public key to the remote machine.
local> cd .ssh
local> scp id_dsa.pub user@remote:~/.ssh/id_dsa.pub
Logon into remote machine and go to the .ssh directory on the remote side.
local> ssh user@remote
remote> cd .ssh
Add the client's public key to the known public keys on the remote server.
remote> cat id_dsa.pub >> authorized_keys2
remote> chmod 640 authorized_keys2
remote> rm id_dsa.pub
Next time you log into the remote server, no password will be asked.
Note that ssh setup depends on the ssh client distribution.
Hope this helps.
Thanks for the output from the mpd logfile. Which version of the Intel MPI Library do you have installed? Is it Intel MPI Library 3.2, which was released November 2008? (This information is available in the mpisupport.txt file in the installation directory).
If yes, this might be a known incompatibility between the Intel MPI Library and the latest version of OpenSuSE 11.1 (similar to SLES 11). You can get more details at the following forum thread.
You have two options to resolve this issue:
I_MPI_CPUINFOto proc. You can do so by running:
Let us know if either of those options work out for you.
