SSH is a serious issue. Of course it is not enabled in the default image
of the device, but it is essential for folks who want make really use of the
device. And yes, the ssh daemon is only accepting public key
authentication. But what about bugs (and exploits for such bugs) below the
level of authentication. That's why I requested some kind of firewall
rules to limit access to such ports based on source IP addr, for example.
