Anselm- It looks like I can use a single DHCP3 server to do both dynamically- assigned addresses to non-MAC-identified PCs as well as the ones we have to have MAC-based entries for and assign statically. It's just a matter of leaving the "get-lease-hostnames true;" statement out so it does not conflict with the "use-host-decl-names on;" statement required for the MAC- based entries.
Thanks for your help! -Krishna On Tue, 18 Jul 2006, Anselm Martin Hoffmeister wrote: Am Montag, den 17.07.2006, 10:54 -0400 schrieb Krishna Murphy: > Hey- > > It appears that I need to have two DHCP servers running on one sub-net. > Apparently this causes a conflict with one in particular (inside a router > provided by an ISP) and the DHCP3 server under Debian that I'm using to > identify the workstations (using "use-host-decl-names on;" to make it so) > and thus make the things that pertain to each of them apply.

Making it authoritative will probably not help too much. When two DHCP offers are sent to the client and both look valid (i.e. contain a "filename" or "root-path" resp.), the client will probably pick the one that arrived first. If that happens to be the router's packet, bad luck. I see two viable strategies for you: 1/ Use the alternate DHCP ports (only possible with Etherboot and LTSP WITHOUT vendor PXE) 2/ Create a separate subnet. Reconfiguring the router to send out valid root-path and next-server and filename is probably not possible anyway.
