DNS and nxdomain hijacking
by Warren Bailey 08 Nov '13

08 Nov '13

All, I've noticed a lot more nxdomain redirects on providers (cox, uverse, tmo, etc.) networks lately. How is this being done?? Is it a magic box or some kind of subscription service? Are any of you doing it? //warren

Anyone from Cogent around? Normal support channels aren't getting me anywhere.

100G wave pricing in Pennsylvania
by Edward Roels 08 Nov '13

08 Nov '13

I'm looking for rough pricing or even carriers that can provide a 100G wave in Pennsylvania. If you have some insight into how pricing scales between 10G and 100G offerings (e.g. 100G is usually 5-6x the cost of a 10G), I'm also interested. Off-list replies are welcome. Thanks, Ed

Email Server and DNS
by rwebb＠ropeguru.com 08 Nov '13

08 Nov '13

So I figured a little break from the NSA was in order. I am looking for some info on current practice for an email server and SMTP delivery. It has been a while since I have had to setup an email server and I have been tasked with setting up a small one for a friend. My question centers around the server sending outgoing email and the current practices requirements for other servers to accept email Things like rDNS, SPF records, etc... I am pretty much set on the issue of incoming spam and virus. Probably overkill but it is checked at the Sophos UTM firewall and at the email server itself. Thanks, Robert

Is anyone from the voice side of Bright House Networks Central Florida Division around? I seem to be hitting a CNAM cache on their network and was hoping to get it dumped. Thanks! Nick Olsen Network Operations (855) FLSPEED x106

Upstream / Handoff UPS?
by Kenny Kant 07 Nov '13

07 Nov '13

We have tons of circuits with various providers. Often times the demarc / handoff switch from the provider is not running on battery backup. Sometimes if the demarc device is located in the same room as our equipment we mitigate this and plug the device into our backup systems. Am I wrong to think that the demarc from the provider is a sacred thing that should only be touched by said provider. Thus they should provide their own battery system? Is it normal for this equipment not to be battery protected? We are not dealing with any crazy SLA's however I think it would be standard build practice to put UPS's on your gear. Even if its small handoff switch sitting right next to my switch. :) Kenny

advice on BGP + CARP setup on FreeBSD
by Antoine Beaupré 07 Nov '13

07 Nov '13

Hi fellow operators, We are slowly and carefully joining the fray of autonomous systems and started announcing our own netblock, a first test that started last week. So far, things are going well, but before going further along this setup, I would be curious to hear experience from other operators about the plan we are thinking of deploying. Our requirements: * free software, as much as possible * inexpensive * using existing operating system expertise (FreeBSD or Debian) So far, we have: * our own ASN * a /21 assigned by ARIN * two uplinks deployed (Netelligent and Cogent) * Netelligent announces 3 /24 netblocks for us * we announce the last /24 through a BGP link with cogent We have some horrible diagrams describing the setup here: https://wiki.koumbit.net/RoutingService/RoadMap As you can see, the uplinks are connected directly into a switch, in two separate VLANs. The reason for this is we want to be able to hotswap the routers in case of a hardware failure, but we have understood from Cogent's documentation that this is not a good practice because the links appears up even if the router goes down. What is your opinion on this? Also, we currently testing OpenBGPd for the announcements, and we are very pleased with it. The syntax is clear and it just works, with minimal memory usage: https://wiki.koumbit.net/OpenBgpdMaintenance#Checking_memory_usage However, this seems to be a fairly exotic platform, most people running BGP with Cisco, Juniper or, in some cases Quagga or Bird for Linux machines. Are there recmomendations on using OpenBGP in production? Good / bad experiences? How many people are running Linux routers vs dedicated Cisco/Juniper/etc routers? Finally, we are likely to complete this setup with a CARP (the free equivalent of VRRP) on the inside of the network. FreeBSD can apparently group interfaces and communicate with OpenBGPd - did anyone deploy such a thing here? What are your experiences or advice? Thanks for any advice, A. -- Sous un gouvernement qui emprisonne injustement, la place de l’homme juste est aussi en prison. - La désobéissance civile, Henry David Thoreau
