We probably need /var/log/messages and possibly /var/log/secure from this run to see what went wrong.
So far it looks like authentication failed either due to missing selinux label on .ssh or because of rlogin service not starting as in some another recent ticket

/var/log/messages and /var/log/secure files are attached above.

John

Could you please advise on this one?

Thanks

Peter

[John Hammond]

Saurabh, did you try setting DSH=rsh in local.sh?

[Saurabh Tandan (Inactive)]

John, Yes I did.

[John Hammond]

Can you setup your test nodes and ping me?

[John Hammond]

Need to do ssh-keygen and ssh-copy-id or set DSH=rsh then it works.
