Comcast Support
by Janet Sullivan 22 Jan '15

22 Jan '15

I hate to use NANOG for this, but support has now ended a chat with me twice without fixing anything, they just kicked me off. I'm not getting an IPv6 address on the Comcast provided cable modem/router. I'm not getting a PD. My machines thus have no IPv6. I've hard reset my router 4 times while working with Comcast, and I've been told to do things like switch to a static IPv4 address, which shows a level of clue that is scary. And before that they were convinced it was a wireless problem even though I have a wired connection, and told them that multiple times. I've wasted two hours with Comcast today, and even when I asked for escalation I got nothing. Just hung up on. It's honestly the worst customer support I've ever received. I don't think I ever got them to understand the difference between IPv4 and IPv6.

Actiontec contact for vulnerability disclosure
by Matoi T. 22 Jan '15

During testing I found a security issue with an ISP-provided Actiontec DSL CPE device (model PK5000) and was wondering if anyone had a contact at Actiontec that I could properly disclose this vulnerability to. -- M.

NETGEAR Contacts?
by Jared Mauch 22 Jan '15

22 Jan '15

I’m wondering if someone has any contacts at Netgear they would be willing to forward some information to. While working with their devices one of my colleagues discovered some poor behavior of their embedded DNSMASQ, such as returning REFUSED to DNS queries. eg: $ dig +tcp puck.nether.net. ; <<>> DiG 9.8.3-P1 <<>> +tcp puck.nether.net. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 33649 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;puck.nether.net. IN A ;; Query time: 136 msec ;; SERVER: 192.168.1.1#53(192.168.1.1) ;; WHEN: Thu Jan 22 13:28:59 2015 ;; MSG SIZE rcvd: 33 where a UDP query passes just fine. This is one of a few issues we’ve uncovered, so hoping for someone who can work on building some fixed firmware. Device in question: Netgear wnr2000v3 v1.1.2.10 (latest on website) Is there a mailing list that exists for the purposes of discussing these types of CPE device issues? - Jared

link monitoring and BFD in SDN networks
by Glen Kent 22 Jan '15

22 Jan '15

Hi, Routers connected back to back often rely on BFD for link failures. Its certainly possible that there is a switch between two routers and hence a link down event on one side is not visible to the other side. So, you run some sort of an OAM protocol on the two routers so that they can detect link flaps/failures. How will this happen in SDN networks where there is no control plane on the routers. Will the routers be sending a state of all their links to a central controller who will then detect that a link has gone down. This just doesnt sound good. I am presuming that some sort of "control plane" will always be required. Any pointers here? Is there any other reason other than link events for which we would need a control plane on the routers in SDN? Thanks, Glen

Someone/something is announcing a /32 from our IP space into comcast from a private ASN. Could someone from comcast help at least provide me some more information off-list? Normal support channels are not helping. route-server.newyork.ny.ibone>show ip bgp 74.115.212.130 BGP routing table entry for 74.115.212.130/32, version 2713438548 Paths: (13 available, best #10, table Default-IP-Routing-Table, not advertised to EBGP peer) Advertised to update-groups: 2 64650, (received & used) 68.86.80.4 (metric 69635) from 68.86.80.4 (68.86.1.4) Origin incomplete, metric 0, localpref 100, valid, internal Community: 64650:50001 no-export It should instead look like this. route-server.newyork.ny.ibone>show ip bgp 74.115.212.129 BGP routing table entry for 74.115.212.0/22, version 2674585749 Paths: (13 available, best #12, table Default-IP-Routing-Table) Advertised to update-groups: 2 29944 29889, (received & used) 68.86.1.89 (metric 66845) from 68.86.80.4 (68.86.1.4) Origin IGP, metric 0, localpref 300, valid, internal Community: 7922:89 7922:2900 Originator: 68.86.1.89, Cluster list: 68.86.1.4, 68.86.1.0 -- ~Randy

Office 365 Expert - I am not. I have a customer that...
by Bob Evans 21 Jan '15

21 Jan '15

I have a customer that heavily uses Microsoft Office 365. It's hosted. All the data I see about usage per user appears theoretical. In that the formulas assume people are taking turns using the bandwidth as if there is a patient line of packets at the Internet gas pump. Nobody is clicking at the same time. We all know that is not the real world. Does anyone have any experience with Office 365 hosted that can tell me the practical bandwidth allocation (NOT in KB per month, but in megabits/sec) for 100 users (during normal work hours) needs to be available ? Thank You in advance, Bob Evans CTO Fiber Internet Center

Could someone from Charter that is knowledgable on SV1 and LOA processes please contact me.
by Bob Evans 20 Jan '15

20 Jan '15

Hello, I am having a heck of a time with this Charter order. Today's issue - I was sent an incomplete LOA from the project manager (PM). Basically, asking me for charter's information on port numbers and data for the cross connect at SV1 (11 Great Oaks, San Jose)? Obviously, I can't provided that as I can't read minds. ( If I could, Bill Gates would be working for me. ) At the start...PM sent the field tech out to customer prem to verify the fiber. A month later, did it again. The Charter field tech called "me" asking why he had to go twice. Who's on first? (old Abbot and Costello reference). It's been like this at almost every step on this order which is now many many months behind. I think this is stuck in some sort of order twilight zone. My sales team and my customer is getting upset. Thank You Bob Evans CTO bob(a)FiberInternetCenter.com

Anyone got experience with RAD MiNID? I need to do some L2 protocol tunneling (L2PT), and this looks like it might scratch that itch. -- Tim:>
