$ /sbin/sshd -t Could not load host key: /etc/ssh/ssh_host_dsa_key
The current configuration follows the serveur default.
On CentOS, these default values still contain
the DSA key, but this key is still removed on
CentOS 7 servers by a custom configuraiton.
We should so configure the SSH server host keys part,
without DSA.
