nevot README (by popular request)
by Graham Toal 17 Aug '93

17 Aug '93

NEVOT - A network voice terminal (BETA RELEASE 1.3 03/25/93) (c) Henning Schulzrinne ============================================================= NOTE: The .nevotinit files from versions prior to 1.3 are incompatible with the current command language and should be deleted. DESCRIPTION: The network voice terminal (NEVOT) allows audio-capable workstations to participate in audio conferences across local and wide area networks. Features: - real-time protocols: - NVP (network voice protocol), as used by 'vat' (LBL) and VT (isi) - 'vat' native packet format and session protocol - RTP draft - versions for: - Sun SPARCstation (SunOS 4.1.x and Solaris 5.x) - SGI Indigo (4D Series) and - Personal DECstations [as soon as we can get the DEC audio library to work] - GUIs: - XView - Tk [in progress] - curses - dumb terminal - fully controllable by Tcl-based command language - can serve as gateway for protocol and encoding translation - network transport protocols: - TCP - unicast/multicast UDP - ST-II [currently inoperative] - several independent concurrent conferences, each with different encoding and compression - DES-based voice encryption (U.S. only) - audio encodings: - 64 kb/s (mu-law PCM) - 32 kb/s G.721 ADPCM (Sun only) - 32 kb/s Intel DVI - 24 kb/s G.723 APDCM (Sun only) - 13 kb/s GSM - 4.8 kb/s LPC codec - each site can use different audio encodings - playback and recording of AIFC and .snd audio files - extensive statistics and tracing facilities - arbitrary voice packet length, which may differ for each site - lost packet and silence substitution - setable audio buffer occupancy - configurable adjustment mechanisms for playout delay, VU meter, silence detector and automatic gain control - redefinable session identifier string with variable substitution DOCUMENTATION: A compressed PostScript file describing Nevot is available for anonymous ftp from gaia.cs.umass.edu, as file ~ftp/pub/nevot.ps.Z. INSTALLATION: The sources are available by anonymous ftp from gaia.cs.umass.edu, as file ~ftp/pub/nevot/nevot.tar.Z (compressed tar file). The platform- specific external libraries are contained in the directory pub/nevot/lib.$ARCH. These typically change rarely. ARCH can be either dec, sgi, or sun4. Precompiled binaries are available as well: nevot/bin.$ARCH/nevot.tar.Z For the precompiled binaries, you also need to retrieve the initialization file ~ftp/pub/nevot/nevotinit and rename it to .nevotinit in the directory from which you plan to start Nevot. Unpack the compressed tar files, then execute the shell script compile You may have to adjust parameters within the shell script to your local needs, e.g., the compiler name. You also have to install the tcl library (version 6.7 or later), either the binary version as mentioned above, or from sources to be found in sprite.berkeley.edu:tcl. In order to use the UDP multicast and/or ST-II facilities, you have to install the appropriate kernel modifications. Due to export restrictions, the DES encryption code is available only by e-mail from the author. If you do have the DES code, change the value of the symbol DES in the Makefiles to 1. To enable on-line help for the OpenWindows version, the environment variable HELPPATH should be set to include the source directory where the .info files are located (here, assumed to be /usr/local/nevot/xview): setenv HELPPATH ${HELPPATH}:/usr/local/nevot/xview OPERATION WITH SD: ------------------ sd is a session directory written by Van Jacobson, LBL, available for anonymous ftp at ftp.ee.lbl.gov. The nevot/sd directory contains a replacement for the sd start_audio procedure, which you can insert into your ~/.sd.tcl startup file. Make sure that the directory containing the Nevot binary is in your path. Use at your own risk (i.e., don't blame VJ if it doesn't work...). DIFFICULTIES: ------------- If you experience difficulties, check the problems.tex file in the doc directory. BUG REPORTS: This is a beta release. Please send all bug reports and suggestions to the author at hgschulz(a)cs.umass.edu. New releases will be announced through the rem-conf mailing list (to join the list, send a request to rem-conf-request(a)es.net) I would appreciate if you could let me know how you are using the software.

Solicitation of Tax Evasion--An Example
by tcmay＠netcom.com 16 Aug '93

16 Aug '93

What could anonymous systems be used for? Besides allowing anonymity in posting embarrassing or otherwise "questionable" messages, is there any _commercial_ use? These are questions I hear a lot. Yes, there are commercial uses. Here's a case that just came wafting across the Net: a woman who wants to evade taxes--she states this explicitly--by bartering her labor for some software. (I have no problem with this, being against taxes and all, and knowing that various kinds of untaxable barter exchanges are going on everywhere.) Here's her post (no names have been changed, as she posted publicly): Newsgroups: misc.forsale.computers.mac From: vanous(a)mdd.comm.mot.com (Brendan K. Vanous) Subject: BARTER: graphic design for s/w Message-ID: <1993Aug14.040010.141(a)mdd.comm.mot.com> Summary: would like to barter services for Mac software Date: Sat, 14 Aug 1993 04:00:10 GMT POSTING FROM MY HUSBAND'S ACCOUNT (mine's temporarily inaccessable): Hi. I'm a freelance forms/graphics designer who would like to expand her software library in an inexpensive (& non-taxable :-) manner. Therefore, I would like to propose the following: I will trade any of my design services (business forms, business cards, illustrations, manual formatting, brochures, newsletters, any sort of desktop publishing task that can be performed on a Mac ...) for an equivalent amount of Mac software (got an extra copy of PageMaker 4.1 lying around that you don't need?) All software must be original, with documentation and letter of transferral. NO PIRATED COPIES, PLEASE! If interested, please reply to cyphrkt(a)eskimo.com and I'll reply to you as soon as I possibly can (probably another 1 or 2 days before I get my account back up and running), or contact me at (206) 778-3362 by voice. Thanks! - Cindy Vanous ................. Chances are no IRS types are watching the Net for such solicitations--and the act of making such an offer is probably not itself illegal. The IRS would have to investigate, call an audit, prove taxes were evaded, etc. The existence of her solicitation might or might not be considered. But in an era in which every Usenet utterance is recorde in perpetuity and is available on CD-ROMs for browsing and compilation of databases and dossiers (you all *do* know this, don't you? Don't bother applying for certain jobs if you posted too many times, or even once, to "alt.sex.perversion.whatever"). Furthermore, anyone _reading_ this kind of post can, for example, call an anonymous (semi-anonymous?) tip line run by the IRS. Last I heard, tipsters can get 25% of any taxes collected as the result of their good citizenship. So, what can anonymity of the sort we discuss do here? After all, if she's anonymous, how can a tranaction ever be consummated? (I'll leave aside purely electronic transactions, which could in principle be done fully anonymously, using a combination of "pools" (the "digital democracy walls" I have cited before) and anonymous remailers.) If Cindy were to use an anonymous remailer to post her offer, and then offer a public key that could be used by anyone who wished to respond to her offer, a response could then be posted in the same group. Something like this: "Alice" (really Cindy): "Want to trade consulting for a used Macintosh. If you are interested, use this public key to respond: 3$1k8dRW4..." Bob (really Jack) sees this, decides to offer a deal, encrypts it with her public key (a one-time public key, used just for this deal), and used anonymous remailers to post it in place she is sure to see it (the same newsgroup, for example, or in one of Miron Cuperman's "pools," or in "alt.w.a.s.t.e," etc.). Bob also includes a public key she can use to communicate with him. If they like the general deal, they can then agree (using only their encrypted channel, readable only to themselves, even though they have never met and have no idea who the other is or where they live) on the next step. In a purely electronic transaction, this process can continue digitally and fully securely. If physical goods or money need to change hands, they can agree to meet, to use phones, etc. The risk to Cindy is still there--Bob (Jack) could of course be a government agent, etc.--but at least she is no longer broadcasting her intentions for all Usenet readers, present and future, to potentially see. And no future readers, such as government computer programs set to scan all postings for evidence of such illegalities, can retroactively detect and compromise her. (If no actual physical contact is needed--such as for software sales and consulting--then of course the contact can in principle remain fully anonymous. Even the transfer of physical goods can be done with moderately good security against tracing...smugglers, drug dealers, and hijackers do it all the time. "Fences," they are called. And so on.) This is just one example of how "the little people" can benefit from the schemes we are exploring. Understand that I have no illusions that our friend Cindy will soon be using such methods...but maybe in 5 years. -Tim May -- ..........................................................................

ADICO: Anarchist FDIC
by Kent Hastings 16 Aug '93

16 Aug '93

ADICO: Anarchist FDIC#000# When someone objects to free banking (in gold, for example) on the grounds that unregulated banks will have fractional reserves and have no incentive to stay honest, perhaps describing an Anarchist Deposit Insurance COmpany (ADICO) will ease their fears. A new or relatively obscure offshore bank would gain the trust of potential depositors by agreeing to cooperate with surprise inspections of their gold supply. Depositors would pay a small premium to cover loss from bank failures due to theft or fraud. Cryptographic protocols would need to be developed to allow the ADICO to see a verified total amount on deposit, without revealing anything about any particular depositor. The total should match the physical amount of gold in storage, assuming 100% reserves. Does anybody know of work on this, or think it is worth researching? Kent - <jkhastings(a)aol.com> #000#

A Follow-up
by Cindy Vanous 16 Aug '93

16 Aug '93

To the lady or chap who arbitrates this mailing list: I am sending along a message which I would like to have forwarded to your mailing list. A colleague of mine found my name mentioned somewhat out of context in a letter posted to your list, and I would like a chance to address the issues mentioned therein. Let me start out by saying that I do fully support the perpetuation of encryption and anonymous posting; however, there are some circumstances in which it is neither appropriate nor desirable. My situation represents one of these circumstances. Let me explain: There are certain transactions which the IRS has allowed to be non-taxable. For example, in Washington state, as in several other states, non-luxury food items are tax-exempt. Another tax-exempt transaction is barter. Barter is one of the mainstays of struggling small-farm owners, a method of support between startup businesses, and an excellent way to obtain needed goods and services without the exchange of money, which might not always be available. In my case, I am a startup business owner with limited funds and a need for better software than I currently possess. Therefore, I post to the Internet that I am willing to trade my services for an equivalent value in software. Therefore, I get my copy of Word or PageMaker, and some other cash-low company receives a professional business form or other graphic design project. All perfectly legal, all tax-exempt, according to the IRS' own laws. This is not tax evasion, merely good business sense. This brings me to the following conclusion: even if anonymous posting was available to me (which it very well might be; I haven't pursued information about it), I would have no need or desire to use it. My clients are not interested in playing some sort of spy game, they are interested in making a business arrangement with me. They would very likely not be willing to trust me if I was merely a phantom name from a nonexistant site. Finally, I would like to point out that there is currently a movement on the Internet, pushing for the greater utilization and availability of barter. The IRS left a loophole in their rules, it is up to us to take advantage of it. For more information on barter through the Internet, subscribe to the Fringeware mailing list at the following address: fringeware-request(a)wixer.bga.com Thank you for your time and bandwidth, - Cindy L Vanous --------------- * cyphrkt(a)eskimo.com * --------------- Cindy Vanous, the Cypherkat, graphic artist at large ------------------------------------------------------ Disclaimer: even though I work for myself, my opinions STILL don't seem to be the opinions of my employer.
