Setting up zone file MX record to external mail server

by Dirk Segers

Hi, we've had knot in use for years now and are still using version 1.6.7. I We've recently migrated e-mail to exchange online. I've been asked to update the MX record in the zone to point to mail.protection.outlook.com. I initially tried to simply replace the current value by mail.protection.outlook.com but then the name of the zone is added to the value. This is not a valid record. I see no way to update the MX record to this value. Any suggestions? Thanks in advance for the feedback. Kind regards, Dirk

Changing DNS Operators for DNSSEC signed Zones

by Luveh Keraph

There is an Internet draft ( https://datatracker.ietf.org/doc/html/draft-koch-dnsop-dnssec-operator-chan…) that describes a mechanism to facilitate the operation consisting of changing the DNS delegation for a signed DNS zone. Since this is a draft, I do not expect for Knot to provide support for it already (in fact, I know it does not, for it involves signing a DNSKEY RR, which Knot does not do) but I wonder whether this is something that is in Knot's roadmap?

Newbie Questions: how-to simultaneously DNSsec-sign a zone with two different algorithms

by Pirawat WATANAPONGSE

Dear Guru(s), If the following questions have already been asked, I do apologize and would very much appreciate the pointers to where I can read the answer(s). I am currently ‘running’ a DNSsec-signed zone using Alg-8 [RSA/SHA2-256]. However, I would very much like to DNSsec-sign and publish my zone with two different algorithms (say, Alg-8 [RSA/SHA2-256] + Alg-13 [ECDSA-P256/SHA2-256]) *simultaneously*, in case the client-validators out there cannot process one algorithm or the other (never mind that they both are the ‘MUST’ in RFC 8624). It also is an opportunity to train myself in case I need to ‘add’ the third one (say, Alg-15 [ED25519]) or ‘migrate’ to the Alg-13 + Alg-15 combination in the future. Background Information: 1. I have a ‘hidden server’ acting as ‘The Signer’. 2. ‘The Signer’ feeds the already-signed zone to the visible ‘Primary Server’. 3. The ‘Primary Server’, in turn, feeds all other ‘Secondary Servers’, some of which are not under my control. 4. Unfortunately, currently none of the above servers is a Knot, but I am switching The Signer to Knot. My questions are: 5. What will be the correct configuration for The Knot Signer? I don’t mind maintaining two completely separated ‘Signed Trees’ of the same zone, unless cross-signing (the keys) between algorithms is the best practice. 6. Will there be any special configuration for the ‘Primary/Secondary Servers’? If so, I will then need to inform admins of the servers outside my control. Thank you for any help you can offer, both on and off the mailing list.
