Re: New remailer up
I haven't really kept track of which remailers are how reliable; they're almost all relatively new and experimental, people are hacking software, they go up and down a lot, and I almost never use them anyway. I also don't like keeping track of the syntax and which ::'s are followed by which ##s :-) Julf's anon.penet.fi remailer is serious; he's done a lot of work to get a private machine, payng for a reasonably expensive 64kbps line himself, and has it located somewhere that only 3 people know. (The original was located at a university, and somebody decided they wanted it Closed.) It's also outside the US, which is useful, . On the other hand, it works differently than the one-way anonymous remailers, uses up a substantial fraction of the net.bandwidth into FInland, and costs him real bucks - somebody ought to start a US equivalent and deload him. I'd guess tht extropia is also probably well-run, or at least has good features. But I haven't used it.

How can this be? What about the people who operate his connection point to the net? Wouldn't they know where his machine is located? What is the physical embodiment of his 64kbps line? Can't that line be traced to its terminus? John E.

That started me down an interesting line of thought... You can get spread spectrum radio/data modems that do 256Kbits/sec (Cylink) and can go up to 30 Miles. It is unlicensed in the US because it is limited to .8watts (I think). I believe 10 miles is the limit with an omnidirectional antenna. Spread spectrum should be pretty hard to triangulate on. Remember that the technology came from unjammable military radios. I think you'd have to have a fairly sophisticated scanner to even pick it up. Using a creative arrangement, this could provide a good cover for physical location. (If you could get the server in the back of a city bus or something...)

Not quite. Very few, if any, Part 15 spread spectrum modems do automatic transmitter power control, and as a result they generally run much more power than necessary. That makes you much easier to spot. It also pollutes the spectrum. Even spread spectrum transmitters with tight power control (e.g, our IS-95 cellular system) are easily detected (though not demodulated) with simple AM scanners when you're close enough. Especially when the mobile in question is a long way from the cell and transmitting near full power as a result. On the other hand, if you're not close, any particular mobile will be drowned out by the several dozen others sharing the same channel. Phil
