Software configuration questions: dhcpd and cupsd

posted by [personal profile] emperor at 06:49pm on 30/09/2008 under ,
Can anyone help with these two simple config questions?

Firstly, dhcp. I'd like to be able to say "allocate addresses from this range to any unknown hardware addresses, except [this one]" or, ideally "except [this set]". There doesn't seem to be an option for this in dhcpd.conf...

Secondly, cupsd. The printing protocol it uses (lpd) typically involves sending a username and hostname; I'd like to be able to say "send this anonymised user/hostname pair, rather than the real user and/or host". Is that doable?

Surely cupsd speaks ipp rather than lpd by default?

It may do, but printers.conf has URIs of the form lpd://... in it for the print servers

Ah, CUPS as an lpd client rather than a server. You should just be able to say lpd://username@hostname/queue

Presumably CUPS will still send my hostname in that case, won't it?

The LPR protocol doesn't transmit the client's hostname. Obviously the server's lpd will be able to figure it out from your IP address.

Regarding the dhcp thing, I think you should be able to use deny known-clients within your dynamic pool declaration and then just declare your exception hardware addresses in another scope.

That's right, yes.
