A game system would be ok. I will summarize the responses I get to the net. -- kirk ------------------------------ Date: 25 Feb 85 22:52 +0100 From: Kurt_Ernulf%QZCOM.MAILNET@MIT-MULTICS.ARPA Subject: Research on homosexuality This notice is part of a feasibility study to investigate the possibility of using computer based message systems and conferences to exchange information about topics within the behavioral sciences. For the moment we are preparing a doctoral dissertation at the Psychology Departement, University of Gothenburg, Sweden, and as our research subject will be in the area of human homosexuality, we have chosen that as topic for the feasibility study. Is there anybody working with research on homosexuality, that might be interested in starting a mailing list for conferencing about the topic? Please reply to Kurt_Ernulf%QZCOM.MAILNET@MIT-MULTICS.ARPA or to Sune_Innala%QZCOM.MAILNET@MIT-MULTICS.ARPA ------------------------------ From: adrion%ucbingres@Berkeley (Rick Adrion) To: MDC.WAYNE%MIT-OZ@MIT-MC.ARPA,info-nets%MIT-OZ@MIT-MC.ARPA, To: To: telecom@BBNCCA.ARPA Subject: Re: Electronic Mail Directory Cc: zbbs%MIT-OZ@MIT-MC.ARPA I am sure the folks at the CSNET-CIC will soon reply, but the main problem with nameservers is getting the initial data and keeping the database updated. The NIC uses site liaisons (and the directory is inaccurate, although pretty good), the CSNET nameserver has individuals maintain their own entries (unfortunately there are fewer than one would like). On ARPANET most sites support "finger" a protocol which allows you to ask a site for a persons mail id (you have to know the site). ------------------------------ Date: Thu, 21 Feb 85 12:21:31 CST From: Mike Caplinger <mike@rice.ARPA> Subject: network cartography To: Wayne McGuire <MDC.WAYNE%MIT-OZ@MIT-MC.ARPA>, To: To: Vince.Fuller@CMU-CS-C.ARPA I made an attempt to locate information about the node names and geographic positions of various network hosts. The results so far are: 1) BITNET is well mapped. They have a lat/long database with hostnames. 2) Somebody can map the ARPAnet, since the ARPA directory has a geographic map in it. I was unable to find anyone who had the data, however. (I tried the NIC and various people at SRI.) I have a database with mailing addresses and phone numbers that could perhaps be turned into a lat/long database. 3) The data exists for some USENET nodes, but I couldn't find anyone who had it. I picked up rumors of a project to build a lat/long database, and I know that a poll of sites was done where lat/long was one of the questions, but I don't know where the results ended up. Since links matter in this net, there is an ongoing project to determine the links for purposes of auto-routing. 4) I haven't tried CSNET, but am interested in it. Again, I've seen maps in the monthly CSNet newsletter, so the information exists. I guess looking at BBS systems and electronic mail users would be interesting, but I have no idea where to start. You could always tap everyone's phone looking for carriers, but this seems undesirable :-). - Mike ------------------------------ Date: 21 February 85 13:33 EST From: RMXJITRY%CORNELLA.BITNET@Berkeley Subject: Retraction To Whom It May Concern: I apologize for adding "CCS" to the bottom of my note in the last issue of human-nets.

Berch) Subject: Firewalls (and flames) in sendmail To: header-people@MIT-MC.ARPA Cc: cak@Purdue, mas@Purdue Well, my posting about denying Internet access to students seemed to hit a raw nerve at many sites. Mail is running about 70% in favor of my comments (the tenor of which were to leave well enough alone) and the remainder were opposed, on the various grounds of security, network/gateway capacity, policy, or DoD-related rules. From cak@Purdue: > It's late, and maybe I shouldn't be responding in my tired state, > because I'm going to flame, but why did you send such a useless > reply to the list? We have a real problem, need some help, and you > try to tell us that we should just ignore it. Why must you > question our motives? The reply WAS meant to be useful, and I stand by it. My comment was that you may not have a problem. Many times I have posted a question of the form, "How can I do X?", and gotten the reply that for whatever technical/administrative/commonsense reason, I really DON'T want to do X. And I am thankful for it. > Maybe it's escaped you, but the DARPA Internet is a *research* > network. Our sponsoring agent has specified that ONLY research > users should be allowed access.

I can understand that if you have an ARPANET sponsor breathing down your necks, yelling, "GET THOSE %#$@&#@ STUDENTS OFF THE NET!!" and threatening to yank your funding and DARPA authorization, that's one thing. If that's the case, you truly have my sympathy, and I agree that you certainly don't need my smug assertions about comity. But if not, I'd wonder why you would want to make it an issue. It doesn't take too much close reading of the headers of many of these lists to determine that many institutions have granted more or less general access to the Internet -- for mail purposes -- to their local networks. It is also evident that ARPANET and MILNET gateways and hosts are carrying a fair amount of off-net traffic, much of it destined for UUCP, CSNET, and BITNET nodes. Anyway, the volume of mail (and the intensity of the opinions expressed therein) leads me to believe that student/casual access to internetwork mail service is a problem that isn't going to go away. I believe, as many do, that freedom of information flow should be paramount, and that the value of an internet increases with the number of persons accessible. On the other hand, there are real concerns about resource consumption, security, and network sponsor policy involved. So, what are people doing about this? Are there alternatives that preserve access to the internetwork community while balancing policy concerns? Is this a problem or a non-problem? My apologies for the long posting. Perhaps this discussion should move elsewhere, like info-nets? ---- Michael C.

I wish we could -- but allowing approximately 4500 undergraduate students access to the ARPAnet (even if only through mail) seems, uh, unwise. I'm curious: are there any schools out there that give unrestricted ARPA mail access to all their students (and will admit it)? Mark <mas@purdue> ------------------------------ Date: Thu, 21 Feb 85 10:20 CST From: Giebelhaus@HI-MULTICS.ARPA Subject: Stargate I agree with Ken Laws that Email bombing is not going to do any good. I disagree with the statement that Usenetters will have to pay for a "guaranteed-free unmoderated message stream". New is a very cheap fringe benefit to give to your employees. It can be limited to a some disk space and after hours CPU time. The structure of the usenet is fundamentelly different than ARPAnet. Each site contributes as much as they like and no one can be kicked off the network (unless no site in the world will allow them to dial in). Also, moderation is a potential form of censorship that the usenet has chosen not to implement. Most control is in the form of peer pressure and there is seldom a need for anything more. If there is, the site's administrator is contacted. They do not wish anymore control and there is no reason to have any more control. I can't answer all of Joseph Dehn's questions, but speaking as an administrator of a site that has recently gotten on the usenet and will soon receiving news, I can say their is no reason for backbone sites at all. They will make the news go faster but it will still make it without them. What was the point to Werner Uhrig's message? Was he saying that Frank Adrian's message did not reflect the truth? I feel that Frank's message did make a lot of good points. If backbone sites require moderation, it will hurt the usenet, though I don't think destroy it. Lauren didn't address the moderation issue, but I feel peck@sri-spam had a great suggestion. What is the answer to the liable question? A lot of the news we get on the arpanet comes from the usenet so this does affect us. Perhaps some who can read net.news and net.news.stargate could summarize what is happening. ------------------------------ Date: Thu, 21 Feb 85 11:54:54 pst From: dual!fair@Berkeley (Erik E. Fair) Subject: Legal Issues concerning USENET Quick summary in answer to the question of who's sue-able over the content of messages on USENET: The USENIX Association retained a law firm to do some research into this area, and one of the senior partners in the firm gave a report at the last USENIX Conference, last month in Dallas. The USENET (legally) can fit into either of two existing classifications: 1) A Common Carrier 2) A Broadcaster but it does not fit clearly into either because it is a new sort of beast. As I understand it, Common Carriers (e.g. AT&T, MCI, US Postal Service) are not responsible for the content of the information that they transmit from place to place. Broadcasters (e.g. ABC, WTBS, NPR) are subject to regulation by the Federal Communications Comission, and are responsible for the content of the information that they transmit (i.e. no obscenity, pornography, etc.). USENET is different in that it uses the techniques of a Common Carrier to achieve the effect of a Broadcaster. USENET is a store-and-forward network, wherein any message will eventually reach all points in the network (unless the distribution is restricted; there are a number of restricted distributions covering specific geographic areas (e.g. the S.F. Bay Area)). Clearly we wish to be considered as a Common Carrier, and not a Broadcaster. Stargate changes things in that we would be using the methods of a broadcaster to achieve the effect of a broadcaster, and it pushes the nature of USENET more in the direction of a Broadcaster (legally) and there would be an apparently singular source of all submissions (not really the case, but the casual observer might assume so) which would be subject to legal attack in a way that no singular USENET site is today. The suggested solution to this problem is one that has been in use on the ARPA INTERNET for quite some time (but for somewhat different reasons): moderation of content. As all of you are probably aware, the HUMAN-NETS digest is moderated by Charles McGrew of RUTGERS. He has been doing it for about the last two years (I think it has been that long), and has done an admirable job (Take a bow, Charles). The INTERNET community has never really had problems with this format (at least none I've been aware of in the last four years that I've been a user of the INTERNET), and so the issue of moderating a list is mostly concern over timeliness of the mailing. Not so on USENET. There has been great hue and cry that ``moderation'' is just another word for ``censorship'', with the many bad connotations which that word has. And, of course, the USENET has the same problem that the INTERNET community has in finding good, willing moderators. I don't know what the resolution of the discussion will be, but I'm in favor of moderated groups because in general they present (at least on the INTERNET) a higher quality level of content with reduced quantity (e.g. when someone asks, ``Does anyone know foo?'' the moderator takes one or two of the best answers and includes them instead of *all* replies received). I'm hoping that this sort of moderation will see a proper test on the USENET and will flourish. Erik E.
