You will need to allow incoming SSH connections on the machine to which you are connecting but you don't appear to have got to that stage yet. "No route to host" would indicate that there's a basic network connectivity problem between the two machines in question. Check you can ping the machines from each other, I suspect you can't. Most likely you've got a typo in a netmask or something similar. Charlie
