Re: [knot-dns-users] Converting from PowerDNS to KnotDNS on Active Realtime AnyCast DNS Network

Hi, > How would one go about converting from PowerDNS to KnotDNS on an active > realtime AnyCast DNS network with maximum seamless efficiency or minimal temporary > disruption of services to existing DNS users? > If it's truly anycast it should only be easier, I would simply: - stop announcing the anycasted prefix at node #1 - once you see no queries anymore: convert and test - after finishing: switch on routing - repeat untill node #last Unless you have bizarre performance complications, above would be more safe than converting an active node. Did I maybe misunderstand the question? Or did you mean: "how to convert from pdns with a transactional SQL backend to a conventional DNS setup with Knot" ..? Leo

Knot DNS and IN NS records

by Eugene Bolshakoff

Hello All, I've decided to use Knot DNS as secondary nameserver for my local zone. I have several subnets connected via VPN and they have their own nameservers. So, there are records in my zone zu-gw.vpn.mithril. 3600 IN A 172.19.0.6 zu.mithril. 3600 IN NS zu-gw.vpn.mithril. and I want to resolve domain in zu.mithril: BIND (master): # dig @tessa.mithril melissa.zu.mithril ; <<>> DiG 9.8.3-P4 <<>> @tessa.mithril melissa.zu.mithril ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 7626 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;melissa.zu.mithril.

by Ret Law

How would one go about converting from PowerDNS to KnotDNS on an active realtime AnyCast DNS network with maximum seamless efficiency or minimal temporary disruption of services to existing DNS users?

Knot DNS v1.6.1 release

by Jan Kadlec

Hello list! Today, CZ.NIC Labs are releasing a new version of Knot DNS. This release introduces a new feature and fixes few bugs. The new feature is a support for Single Type Signing Scheme in automatic DNSSEC implementation. As far as bugfixes are concerned, we've fixed a couple of problems with IXFR/DDNS journal file. Most importantly, it was sometimes not respecting its file size limit (ixfr-fslimit configuration option). We've also fixed incompatibility with OpenSSL 0.9.8. Full changelog: https://gitlab.labs.nic.cz/labs/knot/blob/v1.6.1/NEWS Sources: https://secure.nic.cz/files/knot-dns/knot-1.6.1.tar.gz https://secure.nic.cz/files/knot-dns/knot-1.6.1.tar.xz GPG signatures: https://secure.nic.cz/files/knot-dns/knot-1.6.1.tar.gz.asc https://secure.nic.cz/files/knot-dns/knot-1.6.1.tar.xz.asc There are not many changes in this release, but those of your who use IXFR or DDNS should definitely upgrade.
