meeting network
by Randy Bush 11 Oct '11

11 Oct '11

perhaps as an educational exercise in network troubleshooting whoever is operating the meeting network could explain what the frack is wrong with the meeting network, how it is being debugged, and what they have learned about the cause of the suckage. randy

Y'all know Google is offering public DNS services now?
by steve pirk [egrep] 11 Oct '11

11 Oct '11

I saw this in a post from Travis Wise of Google yesterday. Pretty cool for those users who do not want to use their ISP's name servers, or just want to have dns resolve quickly from anywhere in the world. In either case, I think it is cool ;-] http://code.google.com/speed/public-dns/ Here is the original post - Yes, this one is public... oops! https://plus.google.com/111937447827665620879/posts/27S6QB8j1Ry Nice easy numbers to remember too. 8.8.8.8 and 8.8.4.4 -- steve pirk yensid "father... the sleeper has awakened..." paul atreides - dune kexp.org member august '09

EP.net and Almond Oil Process LLC?
by Chris Griffin 11 Oct '11

11 Oct '11

Anyone know what the current status is with EP.net and their new owner/parent company Almond Oil Process LLC? Some on this list may use EP.net services and have noticed the happenings of late. We contracted with EP.net for exchange space when it was owned by Bill Manning. Apparently it was sold and since then things have gone downhill. We were trying to get a simple authority record changed to no avail despite dozens of contact attempts, and now it appears the ep.net domain is functionally gone, which is causing even more issues. Any hints or current contact information would be helpful. Calls/email to ARIN POCs currently go unanswered.

2011.10.11 NANOG53 tuesday morning session notes
by Matthew Petach 11 Oct '11

11 Oct '11

Wow. People drank too much coffee this morning, they were talking at warp 10. Especially that Todd Underwood fellow; someone swap him out onto decaf next time. ^_^; Video stream worked much better today than yesterday, though VLC stream seemed to be running a bit odd, so I switched back to web stream instead. Notes from the morning session are posted at http://kestrel3.netflight.com/2011.10.11-nanog53-morning-session.txt in case they might be of use to people following along remotely. Thanks! Matt

new guest room SSID for NANOG
by Noah Weis 11 Oct '11

11 Oct '11

All, The hotel is in the process of deploying an SSID throughout the guest room network that terminates to the NANOG external router, rather than the hotel's gateway. The SSID is NANOG-guest. They stated it will take a couple of hours to be fully operational in the guest room space. As always, please let me know if you have any questions. Cheers, Noah -- Noah K.

SP / Enterprise design (dis)similarities
by Tom Lanyon 11 Oct '11

11 Oct '11

Hi all, Looking for some advice or experience in a small enterprise / hosting provider context. There's plenty of BCP information around for SPs in the network design realm, and I'm curious how much of this applies to enterprises too. Commonly advised items like: * pull-up statics created on core devices, not network border devices * using iBGP to carry customer prefixes, not an IGP * announcing defaults over iBGP or IGP In some cases I imagine it may be simpler to have all BGP finish at the network border devices and not have to worry about running both IGP and iBGP sessions inwards to the core and/or aggregation devices. I understand the limitations of putting our Internet prefixes in an IGP, but for a hosting provider style network where everything is ethernet connected and within data centres there's much less route flapping to deal with (there's no bouncing DSL lines, for example). In the case that there is both iBGP and IGP running internally, is there any reason to choose one or the other to originate a default route to our aggregation/access layers? At some point I imagine it's going to be redistributed into the IGP (or re-originated in the IGP), so would think it would be best to just always run the default in the IGP to keep things consistent. Finally - are there any reasons to avoid running next-hop-self on ibgp sessions? The upside is we get to avoid distributing all of our transit/peer upstream point to point links into the rest of the network. Again, I understand this may be undesirable from a SP perspective, but when our 'clients' are all a bunch of internal servers it makes sense to keep iBGP/IGP as clean as possible... Thanks, Tom
