Perry's NZNOG'08 IP-over-something challenge!
I hereby issue the challenge to get IP running over the dishes photographed at: http://unobtainium.braintrust.co.nz/~nward/dishes/ Normally, you'd stand at one and talk, and someone standing at the other would hear you.. you've all played with these before. Perry's challenge is to make two laptops talk to each other, using sound. Note: These photos were taken in winter, which is why those girls have lots of warm stuff on. I have a tshirt on today, but it's raining a little. -- Nathan Ward

Ok, who's got a couple of old acoustic couplers? --David

If you can peer and route traffic across it that would be better. Bonus points for real live networks and AS numbers. -- Simon Lyall | Very Busy | Web: http://www.darkmere.gen.nz/ "To stay awake all night adds a day to your life" - Stilgar | eMT.
How about a couple of old analog modems with 9v batteries to simulate being connected to a line, along with a little audio amplifier / receiver? I see duplex being a problem in that situation, but it's a start... As an aside, we had briefly discussed the possibility of establishing an RFC 1149 IPoAC link for VPN back to the office for our man on the ground at NZNOG but the link quality was deemed unsuitable.

Here's a handy little schematic http://www.jagshouse.com/modem.html for those who want to pursue this ;) Michael Fincham wrote:

How about twelve kilometers of rusty wire which possums have been chewing on, with a small box inserted in the middle within which some third party can randomly re-patch the ends of the wires without any apparent logic or purpose? Might as well make it as real as possible, right? :-) Joe

I'm fairly sure Joe's idea wont work, as Telecom probably wont give access to their NGN for this experiment - although you might be able to get your hands on some of their current PSTN stuff which is a bit lower spec'd... :-) Keith
How about the challenge of IP over chinese whispers between drunk students!

Some old accoustic couplers, with appropriately tinkered mic and speaker i/o, would probably work nicely. It'd probably take longer to hack up some sort of token handler or synced timing system in order to handle who's sending into and who's recieving from the shared audio "media" at any given time - this'd obviously be required for duplex connectivity. JSR
I can just see what will happen. A player will enter the market for acoustic IP transmission between two short range parabolic dishes with Government assistance, a monopoly will form, other players won't be able to freely enter the market, regulation will be formed, and decades of strife will happen. Save NZ now! :-) -----Original Message----- From: J S Russell [mailto:jsr(a)jsr.com] Sent: Wednesday, 23 January 2008 9:17 a.m. To: Nathan Ward Cc: nznog Subject: Re: [nznog] Perry's NZNOG'08 IP-over-something challenge!

Lets not forget that if Perry builds a network between those two dishes, we'll need to make sure that we can so Lawful Interception in the middle if we get a warrant =) iPod with a microphone should do. Dean Nathan Ward wrote:

Wouldn't that interrupt the stream, though? You'd have to put the mic in the middle of the path, which would probably interfere with the transmission. Sounds a bit like quantum theory :P -- Matthew Poole "Don't use force. Get a bigger hammer."
Nah you can stand in the middle and hear both whispers just fine. It's a pretty big beam. Dean Matthew Poole wrote:

No way - look at the beam diameter. You could shove a big-ass studio condenser mic on a stand in the middle of that, and it wouldn't have any noticable impact. JSR

[1] Obviously however, there are limits depending on the size of your particular ass. Also, am I the only one that's noticed that drunk students standing nearby shouting would constitute a pretty simple and hard to defend against DOS? Cheers - N

A 70mm firehose at 700kpa should do the trick quite nicely, and with added humor and entertainment potential. -- Regards, Ed Hintz ed(a)hintz.org

For those who don't understand the terminology, Ed's talking about pouring roughly 15L/sec of cold, high-pressure water on said drunk students. Who, presumably, won't stay drunk for long :P -- Matthew Poole "Don't use force. Get a bigger hammer."

I hade to be a pedant but... actually, no, If I'm going to start a sentence with that I should be honest. I love being a pedant so.. Alcohol is the only drug eliminated by the human body in a linear, rather than in a half life fashion... As a rule of thumb, a person will eliminate one average drink or 15 ml of alcohol per hour. To be unbelievably inane and pedantic though, an individual's ability to eliminate alcohol quickly reduces with age, so if the soaking carried on over a long period of time, you could expect a slightly non-linear rate of elimination. The hose would also presumably either dilute or knock over any alcohol still being consumed, so that would help. The main point is that soaking the aforementioned hackers (yes I know!) with a high pressure hose won't really make them sober up in a pharmacological sense, but it would be great fun. Cheers - N

Whoa there! I was proposing this as a counter to drunk *students* inflicting a DOS, whom I don't mind annoying, because they themselves are annoying(damn kids! get off my lawn!). But I don't want to anger drunk *nznoggers*, because they might shut down my intertubes and that would make me cry like a little girlie. -- Regards, Ed Hintz ed(a)hintz.org

Oh I think they'll stay drunk - they'll just be wet and drunk.
as long as we're being fanciful... you should work it out somehow using a laser based listener like this kind of thing: http://funditor.110mb.com/LaserListener.html On Wed, Jan 23, 2008 at 11:02:07AM +1300, Dean Pemberton wrote:
