All,
This is another strange one. (slightly long message with config and logs -- but just one simple issue)
I have run bind 9.9 and dhcpd with dynamic zone updates (using TSIG) for nearly 20 years (18 to be exact, and with the TSIG whenever they came along). I'm now seeing funny behavior (and this may be related to how the DHCID TXT has is calculated).
What is happening is my sever hands out the IP to the client, and then searches and deletes the record for both forward and reverse zone -- and then doesn't add a forward or reverse zone so name resolution of the client getting the address fails (I see that same behavior in some Linux and some Windows hosts -- but others work fine??) -- that's a new one.
Okay, I think we found the culprit. The dhcpd.leases file had 113 entries, of that one IP was duplicated 47 times (with a number of different IPs) and there were others duplicated a lesser number of times. So I backed up the leases file and stopped the server and pulled-out the big guns... :>dhcpd.leases (sometimes, you just gotta start fresh -- I'll let you know how it goes :) -- David C.
