Hi,
First of all: If you think, I should discuss this somewhere else, please tell
me. :)
During my quest to get my SSH client to use SSHFP records and not annoy me
with trust questions anymore, I fell into the rabbit hole that is DNSSEC.
Our domain already uses DNSSEC, so I only had to set up the resolver in our
office and my PC to verify it.
This however had the side effect that child zones that are not signed were no
longer resolving so I thought "Lets just sign them. Can't be that hard,
right?"
I was very wrong.
One of the child zones is for hosts using DHCP and is managed by dnsmasq that
unfortunately can't sign the zone.
But it can do zone transfers.
So we tried a setup using opendnssec as a signing proxy that transfers the
zone to an unbound.
Unfortunately this has proven unreliable at best and broken at worst so I am
looking to replace that.
I was just looking around for a DHCP server that directly can sign the zone
but I was unable to find something so far.
So I was wondering how other people are doing this.
Are you signing DHCP zones?
Would you recommend (not) doing it?
If you are doing it, how are you doing it?
Kind regards,
Julian
PS: If you are at RIPE86 I also would be happy to discuss this in person :)
