Glenn, Doug, Simon,
Thank you for the excellent feedback. Totally understand about the history/design decisions of dhcpd. I wish I had a piece of code I wrote that is still running for (17) years. :^) I was reading up on reserved leases last night, and it seems that this might help me navigate the requirements set before us. I would assume that editing the dhcpd.leases file is a non-starter for all but the most static of environments due to dhcpd writing to the file and the desire to keep dhcpd running as long as possible. I guess that leaves omapi/omshell. I looked at that a number of months ago and was able to perform a few operations but it was pretty cryptic. I should probably take a second look at that along with the Net::ISC::DHCPd::OMAPI perl stuff. In a failover environment, would I need to connect to each server in the pair and set a given lease as 'reserved', or would the failover communication handle that for me? Is there a compiled cookbook for common dhcpd configurations and/or omapi-related functions?
Thanks again!
Chris
