[Wien] parallel calculation stops waiting for a pass in ssh root at localhost

[Duy Le]

You should check the permission of .ssh and files therein. For
instance:drwx------
.ssh
-rw-r--r--   id_rsa.pub
-rw-------   id_rsa
-rw-r--r--   authorized_keys
-rw-r--r--   known_hosts

If it still doesn't work, open  authorized_keys file and delete lines
related to your host.
Then use ssh-keygen to generate new key without password, then cat
id_rsa.pub >> authorized_keys.

Good luck.
