It does not accept such jobs on 2.1.6-RELEASE (yes, I still have some old 386 system out there with 2.1.6) but it does on 3.x (and as far as I've seen from the code) and 4.x and also on 2.2.6. Why and when has the behaviour of lpd been changed? I'd like lpd only to accept connections from secure ports (do you remember the famous error message `Malformed from address'? ;-) ) Thanks for any reply!
