Control of call setup and supervision is handled by an out of band packet network using a signalling protocol called signalling system 7 (SS7) running over entirely separate data circuits which often don't even take the same paths through the network as the trunk groups they control do.

That would certainly work out the bugs in your development

Its more rewarding to pick an app and enhance it with crypto, and

code protocol after protocol out of some academic texts, don't you think?

Glue is not the problem. Finding a reason to spend time implementing
protocols is the problem. Then the problem is getting what you've built
deployed then used enough to be self-sustaining.
Along the way you can do a clean design and make an API usable by others.

So use a 'simple' library to build a protocol library.
Otherwise you'll have to wait for someone else to get the motivation.

Re: Wired News : FBI Gives a Little on Carnivore
Yup, there have been two cases reported in Minnesota media recently of "observers" being taken away to jail. In one, in Duluth, a guy who had drunk several beers, was walking home, thru an alley, saw a guy laying on the ground with a rent-a-cop standing nearby. He asked what was going on, the wannabe-pig said he had called 911, so this fellow talks to the guy on the ground, telling him that the pigs were on their way, would he like to get up and walk, etc. Then the pigs arrived, told the observer to move on, he asked why, wouldn't go, they took him to spin-dry, where he spent several days, at his expense, and was released with the warning that next time it would be a minimum of 60 days. Nice write up in a local alternative paper. The other was a retired sheriff of a rural MN county. He was talking a writing class, saw some Minneapolis cops rousting a homeless person, stopped to observer, was taking notes, got himself arrested and spent several days in jail. Nice piece on it on Minnesota Public Radio awhile back. Obviously little concern for the Constitution these days by pigs, eh?

Perhaps someone else has put some thought into this and has some ideas.

I can live with that. (Which is not to >say that the predators should not be resisted). Digression on "rent-seeking behavior." In an effort to stave off corporate extinction, the loss of all of their IPO dreams, and the laying-off of their employees, Napster will probably "cut a deal" with the RIAA. I don't know what form this deal will take...perhaps some subscription system with fees kickbacked to the record companies, perhaps some system where an artist must explicitly give permission for his or her works to be indexed, whatever. "Rent-seeking" is where someone seeks to collect some toll, some fee, based on any of a number of points of alleged right to collect such fees. Copyright is one form. Napster will likely seek to survive by this kind of rent-seeking: "Hey, we came to an honorable arrangement with the RIAA, as part of the settlement. Now, Judge Patel, we want you to stop these pirates running Gnutella, Mojo Nation, and Freenet!" A corporate entity like Napster, with hundreds of millions of bucks at stake (seed money, expected IPO money), will not simply say "OK, you win. We're liquidating the company." Even as the appeals continue (fruitlessly, I predict), they'll be looking to cut a deal. Then they'll be rent-seeking and seeking to shut down those other services. Perhaps Lars Ulrich will even join their board. --Tim May -- -:-:-:-:-:-:-: Timothy C.

Login to the box, and run top when it's not under high load. Note how much RAM each Apache process is eating up. Open a few connections, count again, et. repeat until you see the OS moving some of the apache's to swap. Set the MaxClients setting in httpd.conf to that number minus one or two. Increase the MaxRequestsPerChild to something like 50 or 100, that way they'll get reused longer. Turn the KeepAlive parameter on. Should JYA be slashdotted/druged/wired/usenetted, etc, the load would prevent mostly everyone and their mother from seeing the content, however, it wouldn't cause the server to thrash and ultimately die. Which means once the traffic requests slow down, the browsers will be able to get at the content. I think what might help JYA is to one more thing: Rather than setup mirrors everywhere, setup a single private mirror that feeds a wide bunch of SQUID servers. If we could get a few willing folks to run Squids that feed off of this private mirror, the popular files would be distributed amongst them and the site would stay up. Further, this wouldn't require JYA to actively push content to more than one server at a time, so that eases web management up a bit. He'd also need to setup some sort of round robin DNS, or a CGI script that randomly munges the urls to point at such squids rather than the main site. Sort of a poor man's Akamai net. :) IMHO, I think this is a good solution, and won't require lots of hard drive space, although personally, I would welcome having live copies of cryptome on my spindles. :) -- --Kaos-Keraunos-Kybernetos--- + ^ + :Surveillance cameras|Passwords are like underwear.

It passes DIEHARD, but I don't know if it goes through the "proper" stages (if that is needed) - that is, I don't know if the standard implementation of Yarrow would generate the same numbers when starting from the same state (no external entropy being added, of course). Is there some set of "proper state (key and counter) and generated value" pairs? Has someone attempted to do this before? Should I bother?

internet robustness analyzed
Scientists spot Achilles heel of the Internet Updated 2:29 PM ET July 26, 2000 By Patricia Reaney LONDON (Reuters) - The complex structure of the Internet makes it resistant to errors or failure but is also its Achilles heel, scientists in the United States said Wednesday. Because the system is so varied, if one or more nodes --- the crossroads through which Internet data travel -- go down, it has very little impact. But researchers at Notre Dame University in Indiana, who have analyzed the connections within the Internet, have found that if the networks with the most highly connected nodes were attacked by cyber-terrorists it could fragment the Web into isolated parts. "The Achilles heel (of the Internet) is that the structure has this double feature. Like Achilles it is very hard to kill it, but if you know something about the system then you could," Albert-Lazlo Barabasi, a structural physicist, said in a telephone interview. An estimated 3 percent of nodes are down at an given time but no one notices because the system copes with it. "The reason this is so is because there are a couple of very big nodes and all messages are going through them. But if someone maliciously takes down the biggest nodes you can harm the system in incredible ways. You can very easily destroy the function of the Internet," he added. TOPOLOGY OF INTERNET SIMILAR TO US AIRLINE NETWORKS Barabasi, whose research is published in the science journal Nature, compared the structure of the Internet to the airline network of the United States. The majority of airports are small but they are all connected to much larger hubs -- cities such as Chicago, Atlanta, New York and Los Angeles. "That's exactly the situation on the Internet: there are a couple of hubs that are crucial to the system," he explained. Those big hubs or nodes control the traffic in the system. If the Internet hubs are taken out simultaneously, there would be a serious problem, but Barabasi said the probability of random errors hitting the big nodes was very small. In a commentary on the research, Yuhai Tu of the IBM T.J. Watson Research Center in New York said the research was a first step toward understanding the robustness of the Internet. "The good news is that we do not have to worry about random fluctuations of these networks. The bad news is that Internet terrorists could cause great damage by targeting the most connected router," he said.
