The Skid-mounted C3Spear in a NEMA4 version would work perfectly for this application. http://www.ellipticalmobilesolutions.com/c3spear.html

Single AS multiple Dirverse Providers
by Dennis Burgess 18 Jun '13

18 Jun '13

I have a network that has three peers, two are at one site and the third is geographically diverse, and there is NO connection between the two separate networks. Currently we are announcing several /24s out one network and other /24s out the second network, they do not overlap. To the internet this works fine, however, providers a/b at site1 do not send us the two /24s from site b.. We have requested them to, but have not seen them come in, nor do we have any filters that would prohibit them from coming in. Is this normal? Can we receive those routes even though they are from our own AS? What is the "best practice" in this case?

10gig coast to coast
by eric clark 18 Jun '13

18 Jun '13

Greetings I may be needing 10 gig from the West Coast to the East Coast some time in the next year. I've got my ideas on what that would cost, but I don't have anything that big. This could be a leased line, part of a cloud with Verizon, NTT, Sprint, or whoever as the provider, etc. I'm just looking to see what a budget cost for something like this is, and who can provide such service. Your help is greatly appreciated, feel free to respond directly or to the thread. E

recommended outdoor enclosures
by Chuck Anderson 17 Jun '13

17 Jun '13

I'm in need of my first free-standing, pad-mounted outdoor enclosure, 19" rack rails, 12-18 rack units, with about 400W of heat load inside, for use in the Massachusetts climate. What do people recommend as far as contruction, cooling/heating options, NEMA ratings, security options, etc. for this use? I was hoping to keep the inside temperature between 50 and 85 degrees Fahrenheit, although my worst-case components are rated for 41 to 104 F (4 - 40 C). If a full mechanical A/C system can be avoided, even better. A thermo-electric cooler would be nice. Thanks.

Why is it so difficult? Hiding communications is an intriguing subject - My ears perked up a bit at the Multics remark - Morse is something that probably never would have even crossed my mind.

How ISP's in ARIN region create automatic prefix-filters?
by Martin T 16 Jun '13

16 Jun '13

Hi, as I understand, ARIN whois database does not contain "route" objects, which are used for example in RIPE region for automatic BGP prefix filter generation. How does this work in ARIN region? I know that at least some ISP's operating in ARIN region use their own whois databases(for example rr.level3.net) which mirror content from other RIR databases, but are there other methods how they update their internal databases with records? regards, Martin

Blocking TCP flows?
by Eric Wustrow 16 Jun '13

16 Jun '13

Hi all, I'm looking for a way to block individual TCP flows (5-tuple) on a 1-10 gbps link, with new blocked flows being dropped within a millisecond or so of being added. I've been looking into using OpenFlow on an HP Procurve, but I don't know much in this area, so I'm looking for better alternatives. Ideally, such a device would add minimal latency (many/expandable CAM entries?), can handle many programatically added flows (hundreds per second), and would be deployable in a production network (fails in bypass mode). Are there any COTS devices I should be looking at? Or is the market for this all under the table to pro-censorship governments? Thanks, -Eric

Spam to NANOG-specific email addresses?
by Jima 16 Jun '13

16 Jun '13

Esteemed colleagues, Did anyone else get a Twitter invite from @washsuntimes to their NANOG-use-only email addresses? Granted, mine was with my old one, but it was still very much specific to this list. Maybe not the best place to harvest addresses. Jima
