Meade uses the same COTS crap as you are forced to deal with? Bwah hah hah. Gilmore et al used a bunch of old Sun Chassis for his & Kocher's DEScracker. You think this is somehow more than 100 watts, in a diplo suitcase, nowadays? Just curious as to the depth of navite in the field....

I'm sorry but I have to puke at your cluelessness. Do you actually think the folks in the Know would let *your kind* know of their taps? Frankly, you trolls are too easy; but you're probably not, which is even more painful. Take it as a compliment, if there really is a TD.

Not that much, if all you need to do is send a spliced copy over to your own undersea Optical Fiber Amplification node or undersea DWDM OADM. As for the cable landings, likewise I've never heard anyone mention that they saw any government equipment at the landings, so I suspect it's relatively minimal. A the least, it's a splice over to the FDF (THAT they've seen). At the most, they have a card in the carrier's transport gear where they've dropped-and-continued some of the traffic. I guess the question arises as to whether the FBI, for instance, shares it's network with the NSA. -TD _________________________________________________________________ Dont just search. Find.

Yes, but I think it's fairly clear that if one needs to dissasemble the OC-Ns in the field, you simply need too much gear. It's going to be far easier to grab whole swathes of it and ship it back to Montana or wherever for it to be sifted through later. What they probably do, however, is grab specific DS1s/3s locall and switch those via CALEA back to optical access points, where all of this stuff is pulled together into OC-192s or (very soon) OC-768s. As Variola suggests, once you get it back then you can plow through it at your leisure. Got a disident you want to shut down?

Variola wrote... Dark fiber. "Dark Fiber" ain't a talisman you merely wave at data to get it to magically move to where you want it to.You've got to LIGHT that fiber, and to light that fiber you need LOTS and LOTS of power-hungry, space-occupying equipment. In other words, you'd need to duplicate a significant fraction of the current public transport network. And that can't be done in one location, you'd need this shadow network to have either it's own COs all over the country, or to have significant POPs in practically every CO in the country. And I can tell you unequivocally that neither are the case. What this points to is CALEA + Grooming + Massive Optical Transport for offline sifting in a few centralized locations. And I strongly suspect that the recent GIG-BE contract is precisely the massive optical part. What I get from what you've pointed out, however, is that processing power isn't the limitation any longer. If they COULD get it ALL, then they probably would. So perhaps that's just a matter of time (ULH systems can move lots of traffic very long distances these days, with only the occasional optical amplifier.) -TD >From: "Major Variola (ret)" <mv(a)cdc.gov> >To: "cypherpunks(a)al-qaeda.net" <cypherpunks(a)al-qaeda.net> >Subject: Re: Email tapping by ISPs, forwarder addresses, and crypto >proxies >Date: Tue, 20 Jul 2004 21:00:49 -0700 > >At 10:12 AM 7/19/04 -0400, Tyler Durden wrote: > >"Gimme an intel IXA network processor and no problem.
