The pre-release of NSD 4.10.0 is now available. This version of our #OpenSource authoritative #DNS server dramatically speeds up zone loading and IXFRs, up to almost four times faster than the previous implementation! 🏎️
Our new SIMD-capable #DNS zonefile parser is now part of the NSD main branch as a submodule. We'll finish the latest tests today and then make it available as a pre-release to allow you to test the speed improvements. We're curious to hear how this performs in your systems! https://github.com/NLnetLabs/nsd/pull/328
Why yes, I would love to restart my work laptop because macOS has forgotten how to DNS again, and I can't seem to reset it without a reboot.
With that last detail, I'm going to blame it no the various filters, DNS blockers, etc. provided by IT. At least one of them looked dead (or in distress) this morning.
I wouldn't hate these things so much if they didn't impact productivity so severely. Literally four, just for the network.
More straws on the #DNS camel: another #IETF draft to amend RFC 1035. :)
"4. Updates to RFC 1035
A DNS message with OPCODE = 0 (QUERY) MUST NOT include a QDCOUNT parameter whose value is greater than 1. It follows that the Question Section of a DNS message with OPCODE = 0 MUST NOT contain more than one question.
A DNS message with OPCODE = 0 (QUERY) and QDCOUNT > 1 MUST be treated as an incorrectly-formatted message. The value of the RCODE parameter in the response message MUST be set to 1 (FORMERR)."
Am I just lucky, or is macOS' response to "oh noes, I can't DNS" to basically break its own network so hard a reboot is required?
I would've looked up the instructions for restarting the DNS daemon(s) but, you know, no Internet. I did try turning Ethernet off/on again, but that didn't help.
Apple's software quality has really gone downhill in the last 10 years. I assume nobody gets promoted for fixing bugs…
Every so often, I need to chase down some aspect of email validation (#SPF, #DMKIM, #DMARC, ...). This involves a number of #DNS records and queries, but I may forget just which ones. So here's a quick #SMTP/DNS cheatsheet:
Apparently the #SciHub censorship in #Germany is "just" a #DNS block, so it's not very elaborate.
But that's not the point. The point that people even DARE to do this type of censorship in the first place. This is #evil and wrong.
This is the result of #copyright ideology taken to its extreme. But I don't think this is the end point. #Copyright maximalists want to further and further a commercialized, expensive Internet only for the privileged few.
domain names cost too much, literally the fakest economy in existence. Yhey just need to cover the funding of ICANN and the IETF which should be no more than 50 furrys (network engineers) and 10 old guys on a board (they work for free they like it).
