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

Other name resolution impacts, as by-products of the Dyn event (e.g. recursive queries limit reached)
by Stefan 25 Oct '16

25 Oct '16

Have not seen any mentions yet, so thought of asking here: has anybody paid attention to other name resolution issues, even outside the Dyn hosted services directly sourced ones? I am talking about what we observed, as result of: https://community.infoblox.com/t5/Support-Central/Support-Central-KB-118-Wh… i.e. "active queue" filled with the Dyn caused event, but leaving thusly no "room", at times, for valid recursive queries, inclusive of internal name resolution, where the SOA sits in another tier (e.g. GSLBs). One possible mitigation for such scenarios is: https://community.infoblox.com/t5/Support-Central/Support-Central-KB-3451-C… Any other related events, on other platforms or configurations? ***Stefan
