I'm trying to come up to speed on the https mechanism, so please bear with my perhaps misguided questions. I replaced the prior magic with: echo `{auth/rsagen -b 1024} 'service=https owner=none' >/mnt/factotum/ctl which gives me: echo: write error: unknown proto rsa Since I don't get the same interaction on the terminal, I guess my cpu kernel is out of date? Looking in /sys/src/9/pc I see there's now a pcauth for CONF. Which one do I want - pcauth, or pccpu? Is pccpu now for non-authenticating cpus? Why does it matter? Any tips would be quite appreciated.

The only difference is the kernel configuration file. An auth server should take its root from a local drive, helping to solidify its security. Network protocols should be limited only to ones needed for incoming auth requests. Finally, unlike a standard CPU, windowing functionality is generally allowed, in order to help the user administrate and manage accounts, etc. Aside from the above, there really is no difference between an auth server and a cpu server. I always use an old, but stable, machine with a local disk. I skip the windowing capability, however, to minimize CPU/RAM usage.

Distributed Name Space... Global Sign-on... Guerrilla Networking... Open Source Technology... Do these words make your heart beat faster and your breath go shallow? If so then perhaps you should become involved with Hangar 18. We are a tit-for-tat group of computer hobbyist of a wide range of skills intent on building the next computing infra-structure using Open Source technology. We don't focus on any one form of technology but instead focus on real world applications in grid or large scale distributed computing. Time: May 22, 2003 Every Thursday, excluding national holidays 7:00 - 9:00 pm (or later) http://open-forge.org Location: We'll be meeting this week at the Austin Robot Group again. If you'd like to come then please contact the Robot Group for directions. http://robotgroup.net The location varies from week to week so be sure to check with an active Hangar 18 member (or join the mailing list!) for more information. Identification: We'll be the group with the Plan 9 OS box on the table...;) ps Rob and I had lunch today at the Filling Station and they have ethernet and possibly wireless (we saw the antenna but nobody there knew where it went ;) for us to access. So, we'll probably begin to include socials at this location as well. pss With regard to Buffalo Billiards, we're looking at having the social sometime the first half of June.

Not to > sound potentially condescending, I really want to know. Tit For Tat (TFT) is a strategy from game theory. It is considered one of the strongest approaches to resolving situations where two or more parties must decide via a 'iterated prisoners dilemma' what to do on the next turn. There are several variants. In short, it means you get to use my stuff because I get to use your stuff. You abuse it you get dropped like a hot potato. At least for the SSZ and Open Forge site we capture all traffic over the network via sniffer and can review it for any strangeness. Another technique we use is that we export our namespace resources read only, except in very special cases to particular individuals or node operators. We couple this with a 'small worlds' network approach; the number of connections per node is limited to ln(number of nodes). Which has some very strong characteristics, though it does have the weakness of getting it off the ground. It's a network application of the 'Kevin Bacon Game' or the 'Six Degrees of Seperation' theory. Studies of the Internet indicate that it's degree of freedom with respect to small world networks is somewhere between 17 and 21. This means that no two sites are farther away than that many hops (which takes us into spanning tree theories from graph theory). The utility of the small world model with respect to 'next neighbor' in the network is that you probably know that person as something other than a stranger. So there is a two fold factor being used: familiarity breeds trust, and it makes it reasonably easy to back track problems. An additional feature is that in tests small world networks seem to exhibit the least amount of congestion under heavy load. You will find several references on the Hangar 18 website to books that discuss these topics. A visit to Google will also turn up quite a few hits on these topics. I can particularly suggest the arXiv repository (eg xyz.lanl.gov). I sent out a 'suggested reading' list this morning to several of the lists and one of these goes into TFT with applications to animal cooperation to some degree. It's not on the H18 list. The book was, Cooperation Among Animals - An Evolutionary Approach L.A. Dugatkin ISBN 0-19-508621-x If you want to learn more than get some books on game theory, graph theory, and network theory. A book on psychology and group cooperation can be usefull as well.
