H-Sphere Control Panel interacts with its Unix-based servers via SSH protocol. For user to have permanent access to H-Sphere remote servers and to log into them automatically without entering password each time, the access keys to the CP box should be copied and added to each H-Sphere server.

Normally, H-Sphere does this automatically during installation. However, sometimes there is a need to generate SSH keys anew. This document will guide you through the process of generating SSH keys on the CP box and adding them to each H-Sphere server.

1. Enter the CP box as the cpanel user
2. Generate ssh keys on the CP box for cpanel user by the following two commands (passphrases must be empty):
   # ssh-keygen -t rsa1
   # ssh-keygen -d
3. Place the public OpenSSH cpanel user keys into the /root/.ssh folder on each box.
   You can find them on your CP box in the ~cpanel/.ssh/identity.pub and the ~cpanel/.ssh/id_dsa.pub files.
   Insert the keys from these files into the /root/.ssh/authorized_keys and the /root/.ssh/authorized_keys2 files correspondingly on each H-Sphere box.
