forcing minimal fragment size for IPv6 datagrams

by Jan Včelák

Hello guys, there has been a request in our issue tracker [1], to enable IPV6_USE_MIN_MTU socket option [2] for IPv6 UDP sockets in Knot DNS. This option makes the operating system to send the responses with a maximal fragment size of 1280 bytes (minimal MTU size required by IPv6 specification). The reasoning is based on the draft by Mark Andrews from 2012 [3]. I wonder if the reasoning is still valid in 2016. And I'm afraid that enabling this option could enlarge the window for possible DNS cache poisoning attacks. We would appreciate any feedback on your operational experience with DNS on IPv6 related to packet fragmentation. [1] https://gitlab.labs.nic.cz/labs/knot/issues/467 [2] https://tools.ietf.org/html/rfc3542#section-11.1 [3] https://tools.ietf.org/html/draft-andrews-dnsext-udp-fragmentation-01 Thanks and regards, Jan

problem with Knot 2.4.0 on FreeBSD 10.3 and 11.0 - i386

by Leo Vandewoestijne

Hi, I tried to install knot 2.4.0 on FreeBSD 10.3 & 11.0. On amd64 these complete fine, however on i386 they don't: https://dns.company/downloads/knot2/knot2-2.4.0_103i386.log https://dns.company/downloads/knot2/knot2-2.4.0_110i386.log Is there anything I can do better to prevent this? -- With kind regards, Leo Vandewoestijne

Upgrade broke journal

by Bastien Durel

Hello, For the second time after an upgrade, one of my knot instance did not restart. (actually, it restarts but does not respond to queries) I got theses messages in log : 2017-03-27T17:11:16 warning: [durel.eu.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:16 error: [durel.org.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:16 error: [durel.eu.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:16 error: [durel.eu.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:27 warning: [durel.eu.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:27 error: [durel.eu.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:27 error: [durel.eu.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:27 warning: [durel.org.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:27 error: [durel.org.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:27 error: [durel.org.] zone event 'load' failed (invalid parameter) removing all files in journal/ directory and restarting it leads to normal behaviour. Do you have hints about these error ? Thanks, -- Bastien Durel

odd delays when a fresh kresd 1.2.4 tries to resolve www.ietf.org

by Daniel Kahn Gillmor

hey knot folks-- I'm running kresd 1.2.4. If i start it with an empty/missing cache, and then receive a query for an A record for "www.ietf.org", there is a substantial delay in the response. I'm trying to debug the delay from the kresd logging output (gathered via systemd's journald) and i don't understand what's happening. I'm attaching the logs from the server and client. The client (kdig), is doing three queries, waiting 10 seconds after one query completes before sending the next query. timestamps of both sides are in UTC. In particular, the delay appears to be related to resolving AAAA records for'ns1.yyz1.afilias-nst.info, but i don't know why. i do note that the first time it shows up it's answered with "=> using root hints", but then subsequent times don't seem to say that. I'm not sure what this means. Note the multiple pauses in the server timeline, as the resolver seems to go quiet. can anyone reproduce this result, or help me to interpret the logs?

ZSK/KSK Key algorithm rollover

by Tobias Brunner

Hi, I'm in the process of changing the key algorithm from the former Knot default of RSASHA256 to the newer default ecdsap256sha256. For this I have just updated the DNSSEC policy and reloaded Knot. This created a new ZSK and signed the zone with this new ZSK, but also with the old one. Now the zone is signed with two ZSKs. How can I get rid of the old ZSK? I already tried to set "retire" and "remove" on the old ZSK with keymgr to a value in the near future, but that just lead to the error message "keys validation failed (missing active KSK or ZSK)" when issuing a zone-sign to this particular zone. So I'm stuck now. Additionally: How can I do a KSK rollover to also change the algorithm from RSASHA256 to ecdsap256sha256? I couldn't find a documentation explaining this step. I know that I need to have two KSKs until the DS record on the parent is updated pointing to the new key, but I don't know how to create a new KSK with Knot. Thanks in advance for explaining the process. Cheers, Tobias

Multi-master scenario

by Giovanni Civardi

Hi, i’m evaluating some DNS solution for our multi-site distributed environment. I do not want a master-slave scenario, but would like to implement some multi-master. do you think is achievable with KNOT? have you ever implemented some master-to-master synchronisation? what could be the benefits having a multi-master scenario against the classic master-slave scenario? thanks!
