Well, actually, I *did* try it out.  And it did *seem*  to work, but what
do I know?  I also tried, but was unable to find where exactly the
smbd/nmdb log records are being sent to, by default, on my FreeBSD system,
and thus, I was unable to check properly to see if my addition of a
line in my smb.conf file like "hosts allow = <<CIDR>>" did or did not
cause a parse error, i.e. when I restarted the daemon.

So, for all I can tell, perhaps I glitched the "hosts allow" directive
and perhaps smbd/nmdb are now allowing *all* hosts to access my stuff.
I was not able to tell if this might be happening, and that's why I asked
the question.

And anyway, isn't it a Good Thing that I asked?  I mean doesn't somebody
maybe want to fix the documentation page that I gave a link to, so that
it will henceforth be clear in noting (which it currently fails to do)
that CIDRs are allowed in hosts allow/deny directives?
