Part 1: Build encrypted tunnel from Xen (HYPERVISOR) to Backup server

ONLY SET THIS UP ON MASTER HOSTS

1.1 Temporarily enable Redhat repositories & perform autossh installation

sudo yum -y --enablerepo=base --enablerepo=updates --enablerepo=extras --enablerepo=base --enablerepo=centosplus install epel-release
sudo yum -y --enablerepo=base --enablerepo=updates --enablerepo=extras --enablerepo=base --enablerepo=centosplus install autossh
