Help with GMail...
by Grant Taylor 23 Jul '15

23 Jul '15

Hi, I was wondering if there were any GMail contacts on NANOG that might contact me either on or off list for some help. I am having problems sending email to GMail from my new (< 2 weeks old) Linode VPS. tncsrv06.tnetconsulting.net (IPv4: 45.33.28.24, IPv6: 2600:3c00:f03c:91ff:fe26:8849) I have forward and reverse DNS set up as well as following all of the same practices that I have used to administer email servers for the past 15 years. So, I think that I have everything covered. (If I've missed something, let me know and I'll take care of it.) Is there a chance that my IP address(es) (v4 and / or v6) have been blocked because of previous IP user actions? Or am I by chance part of a netblock that is black listed? Below is the multi-line SMTP response that is showing up in the DSN that I'm receiving. <<< 550-5.7.1 [2600:3c00::f03c:91ff:fe26:8849 12] Our system has detected that <<< 550-5.7.1 this message is likely unsolicited mail. To reduce the amount of spam <<< 550-5.7.1 sent to Gmail, this message has been blocked. Please visit <<< 550 5.7.1 https://support.google.com/mail/answer/188131 for more information. f5si4126138oeo.56 - gsmtp Any help or suggestions you could provide would be greatly appreciated. I'm in the process of migrating off of my old server to my new Linode VPS as part of a move and would like to get this quickly, if possible. As a temporary work around, I have routed gmail.com email to my other Linode which can send email to GMail. tncsrv05.tnetconsulting.net (IPv4: 109.74.192.125, IPv6: 2a01:7e00::f03c:91ff:fe89:2935) Thanks for your time and any help you can provide. -- Grant. . . . unix || die P.S.

OCP Data Center Spec: Ladder Tray
by Martin Hannigan 23 Jul '15

23 Jul '15

Hi NANOG, The Open Compute Project "OCP" had, at least that I can recall but now can not find, a ladder tray deployment spec in the data center working group. It called for tray to span the middle of the aisle as I remember it. Anyone recall or have a pointer to it? My favorite search engine and the OCP wiki yields nothing. I was also hoping to find someone involved in the spec to discuss a related NFPA issue with. Best, -M<

20-30Gbps UDP 1720 traffic appearing to originate from CN in last 24 hours
by Drew Weaver 23 Jul '15

23 Jul '15

Has anyone else seen a massive amount of illegitimate UDP 1720 traffic coming from China being sent towards IP addresses which provide VoIP services? I'm talking in the 20-30Gbps range? The first incident was yesterday at around 13:00 EST, the second incident was today at 09:00 EST. I'm assuming this is just another DDoS like all others, but I would be interested to hear if I am not the only one seeing this. On list or off-list is fine. Thanks, -Drew

another tilt at the Verizon FIOS IPv6 windmill
by Paul B. Henson 22 Jul '15

22 Jul '15

I think it's been about a year and a half since I last looked (and cried) at the status of FIOS IPv6. As far as I can tell, there's been no new official news since 2013. We're deploying IPv6 at the university I work at, so IPv6 at home is moving from "wish I had it to play with" towards "need to have it to work from home". So it seems I either cancel my fios and go with business class cable (I live in Time Warner territory and it looks like they're good to go with IPv6) or set up a tunnel with HE. Or pray Google fiber comes to my neck of the woods. Any new rumors floating around? Any Verizon employees interested in posting anonymously and explaining what on earth is going on inside the company? Any secret phone numbers to call to get in on an alpha/beta test in the So Cal area ;)? If nothing else, it always feels better to hear other people say how ridiculous this is too <sigh> :). Thanks...

Remember "Internet-In-A-Box"?
by Stephen Satchell 21 Jul '15

21 Jul '15

This goes back a number of years. There was a product that literally was a cardboard box that contained everything one needed to get started on the Internet. Just add a modem and a computer, and you were on your way. No fuss, no "learning curve". I'm beginning to think that someone needs to create a similar product, but for IPv6 internet. The Internet service providers would provide the same sort of kit to get people started. Just add a CSU/DSU (like a cable modem) and a computer, and you are on your way. Also, I think we need a *real* book called "IPv6 for Dummies" (maybe even published by IDG Books) that walks through all the beginner stuff. There's beginner stuff that I've seen by using a search engine; a dead-tree book, though, may well be better for Joe Average. Just my pair-o-pennies(tm)
