IPv6 automatic reverse DNS
by Baldur Norddahl 30 Oct '16

30 Oct '16

Hello Many service providers have IPv4 reverse DNS for all their IP addresses. If nothing is more relevant, this will often just be the IPv4 address hashed somehow and tagged to the ISP domain name. For some arcane reason it is important to have the forward DNS match the reverse DNS or some mail servers might reject your mails. However with IPv6 it is not practical to build such a complete reverse DNS zone. You could do a star entry but that would fail the reverse/forward match test. It should be simple to build a DNS server that will automatically generate a hostname value for every reverse lookup received, and also be able to parse that hostname value to return the correct IPv6 address on forward lookups. Does any DNS server have that feature? Should we have it? Why not? I know of some arguments for: 1a) mail servers like it 1b) anti spam filters believe in the magic of checking forward/reverse match. 2) traceroute will be nicer 3) http://ipv6-test.com/ will give me 20/20 instead of 19/20 (yes that was what got me going on this post) 4) Output from "who" command on Unix will look nicer (maybe). Regards, Baldur

Yet another NTP security bug we fixed before the CVE issued
by Eric S. Raymond 29 Oct '16

29 Oct '16

http://forums.theregister.co.uk/forum/1/2016/10/28/researchers_tag_new_brac… That'd be another CVE that NTPsec dodges before it's issued. We removed interleaved mode months ago because the code smelled bad and turned out to have an implementation error in the timestamp handling. On past performance, there'll be about a 75% chance each that we've pre-fixed the other new security bugs. -- <a href="http://www.catb.org/~esr/">Eric S. Raymond</a>

What incentive do the ISPs have to enforce any of this though? In fact, they're making money sending bits over these prefixes. What incentives could be created that the ISPs wont balk at as it might affect their accidental revenues from "oh, gee, I didnt know it was being squatted! <wink>" prefixes? /kc -- Ken Chase - math(a)sizone.org guelph canada

Hello folks - I work for a ticketfly.com - a company that changed a lot of DNS records on wednesday, that are resolving correctly around the world... except Bell CA. If anyone here is @bell.ca and willing to beat their DNS servers briefly on my behalf, I would be very, very grateful. Currently racing against several coworkers stuck in the phone tree/tier 1 customer support

Should abuse mailboxes have quotas?
by Stephen Satchell 28 Oct '16

28 Oct '16

For the last couple of weeks, every single abuse mail I've tried to send to networks in a very short list of countries has bounced back with "mailbox exceeds quota". I take this to mean that there isn't someone actively reading, acting on, and deleting e-mail from abuse@<whomever>. So my new rule is this: bounce an abuse e-mail message, sent to an abuse address announced for the netrange, and the ENTIRE NETRANGE gets put in my "reject forever" firewall. I've ask all my customers about this action, and all agree that it's reasonable, because an administration with an active abuse desk shouldn't ever have their abuse mailbox overflow. (Especially in this day of terabyte disks.) Or they need more people on their abuse desk. Or they need to eliminate the problem that generates so many abuse e-mails that it fills up their should-be-enormous mail queue. I'm tired of blatantly uncaring administrations.

What is it? 20 years? since the first time I was banned from NANOG for saying that the world would be a nicer place if EVERY true router refused to forward a packet whose SOURCE could not be reached from the port question. (May not be stated clearly, but idea seems simple enough: If the proposed ICMP message would not be routed to the port the packet came from, the best plan is probably to log the event and drop the ICMP and the rogue packet on the floor.) -- "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." --Albert Einstein From Larry's Cox account.
