You can't, and no one is denying that as far as I can see. And I'd
actually consider this to be failing on the safe side.
But, given an entry in hosts.allow like this:
mountd:
host.example.com 192.168.1.1
denying the ip 192.168.1.1 just because it does not have a hostname
associated with it would be just wrong.
Remember I said _matching_ IP... meaning if
the above line
was in hosts.allow and client 192.168.1.1 did a mount
the client would be allow the mount without doing a lookup
because there was a matching IP address entry...
Now if client 192.168.1.2 did a mount, there would not be a
IP matching entry in hosts.allow so a lookup would be necessary
to see if a 'mountd: <hostname>' exists in hosts.deny.
Is that making sense?
