Hi,

I have installed the following version of openssh in my cluster:

openssh-5.3p1-70.el6.x86_64
openssh-server-5.3p1-70.el6.x86_64


I am trying to configure ssh to allow users to run mpi programs in my cluster, then I need to configure ssh properly.

I have tried the following:

1.- I have created the /etc/ssh/ssh_known_hosts file using

ssh-keygen -t rsa hostname


2.- Client configuration /etc/ssh/ssh_config

RhostsAuthentication yes
RhostsRSAAuthentication yes
HostbasedAuthentication yes
EnableSSHKeysign yes

3.- Server configuration /etc/ssh/sshd_config

RhostsAuthentication yes
RhostsRSAAuthentication yes
HostbasedAuthentication yes
PAMAuthenticationViaKbdInt yes

4.-Copy etc/ssh/ssh_known_hosts in all the cluster nodes


5.- Create the /etc/ssh/shosts.equiv with the name of all the cluster nodes.


But, it doesn´t work, what can i do? Can anyone help me?

Regards,
Alicia Acero

Ssh passwordless configuration problem
 
Might be a perms issue since you didn't use SSH key copy. Check to make
sure the. SSH sir in the users home dir is 640
