Passwordless SSH for Cluster need help
 

Hi,
Actually i m unable to achieve paswordless ssh. Without this i cannot successfully install MPICH.
What i have did
- server's /home is shared with the nodes
- kuser on a node has generated its key like
ssh-keygen -t dsa
which is saved in /home/kuser/.ssh of the node.
- now i have copied this key(id_dsa.pub) to server's /root/.ssh/authorized_keys
scp /home/kuser/.ssh/id_dsa.pub server:/root/.ssh/authorized_keys
- then i have restarted sshd....

Still password asking.. kindly solve

if rsh is easy to use for a cluster tell me that

I can't remember the configuration options, but look in your ssh config file, you have to enable this option, it isn't enabled by default to my knowledge.

Maybe it's because dsa is ssh version 2? Try this:
And, as it has been said, check the parameter
PubkeyAuthentication yes
in sshd_config

ssh
 

Remember, you must set authorized_keys to read only by owner

chmod 600 authorized_keys
