Unable to connect to remote hosts in cluster from cpanel user under root user without password.
Missing necessary ssh keys.
Enter the CP box as the cpanel user. Check if you have SSH public keys generated for the cpanel user.
$ cat ~cpanel/.ssh/identity.pub
$ cat ~cpanel/.ssh/id_dsa.pub
If any of these files does not exist, generate missing SSH key for the cpanel user by the corresponding command (passphrases must be empty):
$ ssh-keygen -t rsa1
$ ssh-keygen -d
Place the public SSH keys of the CP server's cpanel user into the corresponding files in the
/root/.ssh folder on each Parallels H-Sphere box:
Log into an Parallels H-Sphere box as root.
Create the authentication key files for root if they don't exist:
$ touch /root/.ssh/authorized_keys
$ touch /root/.ssh/authorized_keys2
Insert the RSA key from the
~cpanel/.ssh/identity.pub file on the CP server into
/root/.ssh/authorized_keys on this
box, and the DSA key from
