Remove "deny unknown-clients;" and see what happens. When you use 
deny, then anything not explicitly denied is allowed, and vice-versa 
for allow statements. When you use both, I can't remember the details 
of how they interact - but it's not immediately intuitive.

"allow members of ..." is sufficient as it will implicitly deny 
anything not in the named class.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon 
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the disk and re-install the 
printer OS on it. If anyone knows where I might get hold of one I'd 
be grateful - requests to Canon drew a blank, it's been out of 
support for years.
Alternatively, if anyone has one of these and would let me image 
their hard disk ...
