by Max Tulyev 08 Dec '15

08 Dec '15

Hi All, we got an issue today that announces from Cogent don't reach Hurricane Electric. HE support said that's a feature, not a bug. So we have splitted Internet again? I have to change at least one of my uplinks because of it, which one is better to drop, HE or Cogent?

Have you looked into scheduled scans with WarVOX?

Kinda funny and perhaps offtopic, but I noticed the cert for mozilla.org expired right before my eyes when checking my plugins.

Questions regarding equipment for a large LAN event
by Laurent Dumont 07 Dec '15

07 Dec '15

Hi Nanog, This email might seem a bit strange but bear with me. I am a member of a student club in Montreal named "Lan ETS". Every year, we organize on the biggest LAN event in North-America. We have an amazing partnership with Cisco where they allow us to request a fair amount of equipment so that we can create the best experience for our players. This year, we are looking into some equipment that slightly out of our usual expertise. Usually, we target high-density stackable switches like a 3650/3750/3850 with 48 GigE and 4 SFP for our 10G core. We design our network around small "islands" of players all linked with each other through a 2x10G fiber network. Everyone is assigned a public address and we route everyone out through our core switch. We were looking at either the Nexus 7004 chassis or the ASR 9004/9006 chassis for this year event. We would then use 48xGigE and 1x24 SFP+ line cards. Our actual port requirements and somewhat flexible but we do need at least 4x10G Fiber ports. And at least 48 GigE ports for players or access switches. I'm also open to any suggestion within Cisco portfolio. Our needs are pretty standard and nothing extraordinary but we would like to use this opportunity in order to try new equipment and technologies that are usually only seem within ISP and large networks. I appreciate any input on the matter! Thank you -- Laurent Dumont https://coldnorthadmin.com

Google Chrome 47.0.2526.73M broken NTLM proxy authentication
by Seth Mos 07 Dec '15

07 Dec '15

Dear Google, As of Dec 2nd the Google Chrome 47.0.2526.73M breaks NTLM proxy authentication. This is unfortunate as nobody can get off the company network now, which is secure I suppose, but not quite what I had in mind. https://productforums.google.com/forum/#!topic/chrome/G_9eXH9c_ns;context-p… So if anybody gets called that Google Chrome is throwing a username/password prompt for every website you try, listing the website as the authentication domain, instead of the proxy server, this is for you. If you are ahead of the curve, you can make a GPO to disable Chrome updates for the time being until this is fixed. If the browser already updated, well, sorry. Kind regards, Seth

Amazon - Wrong website location
by John Cenile 07 Dec '15

07 Dec '15

Hello, Amazon's website is currently suggesting Amazon India, rather than Amazon USA. So I'm guessing whatever GeoIP database they're using is out of date, but I have updated as many public GeoIP databases I could find. I have emailed their noc@ email address multiple times, but have not heard back from them. Does anyone know where I can fix this up, or who I can contact to resolve this?

DHCPv6 PD & Routing Questions
by Jim Burwell 07 Dec '15

07 Dec '15

Hi, Have a simple couple of questions here. In my admittedly cursory glances over the DHCPv6 RFCs, I don't see any reference to the protocol having any role in managing the routing of prefixes it delegates. Perhaps I missed it, but I somewhat expected the omission of this responsibility would be the case. My questions are: 1) Does the DHCPv6 protocol include any standards/mechanisms/methods for managing routes to prefixes it delegates, or does it consider this outside of its function? (I suspect the latter) 2) What are the most common ways of managing the routing of delegated prefixes in the ISPs routing domain? Has a standard method/best practice emerged yet? Routing protocols? IPv6 RAs? One obvious answer would be routing protocols. In my brief googling, I've seen a forum post that seems to indicate that Comcast makes use of RIPng on their CPE to propagate routing information for prefixes delegated to it. Can someone confirm this? This would seem as good a method as any to do this, albeit with obvious security concerns. What's the best way to implement a DHCPV6 PD client on a Linux router? Dibbler seems to do everything except route propagation (asks for PD, puts PD address on local NIC if asked). Anything better out there? TIA, - Jim

eBay contact that deals with IPv6
by Frank Bulk 04 Dec '15

04 Dec '15

I'm looking for an eBay network engineer to contact me off-list that can dig into an IPv6 performance issue. I started monitoring ipv6.ebay.com a week or two ago and the site times out (10 second timer) regularly. The last seven days indicate it's been timing out about one-third of the time. Frank
