#1 add ssh as remote method

[Florian Hinzmann]

Hello!

It would be nice to have the additional possibility of
using ssh as a method to access a remote tape drive.

There might be some machines where rsh just is not
installed due to security considerations. Ssh will be
there more likely.

Furthermore I don't like the idea of having a user
without password and with tape access. Using ssh and
public key authentication it would be possible to
have a user with tape access which can not be abused
by everyone. "kbackup clients" may use an key without
password or with password which is supplied by a ssh
agent.

KBackup should just provide a possibility to call
"ssh" instead of "rsh" and store some command line
options a user might want to add. This should be possible
without too much changes/addition to KBackup.
Additional ssh/key/agent setup could happen outside
KBackup like it is now with rsh setup.

Thanks
Florian
