[Wien] ssh and keys

[Torsten Andersen]

The error you get indicates that there is a permission problem in your 
nfs, I think. It is not enough that the working directories have the 
same name, it should be identical, and nfs mounted RW on all the nodes, 
and exported on the master with RW permissions. I believe you should be 
able to check this from the shell by logging in and do a cat or more on 
that file. This is not an ssh problem...

Best regards,
Torsten Andersen.
