I'd like the opinion of this August Group. Should I make a claim to be the inventor of the email attachment? (It would go on my web site, resume, the Wikipedia page, that sort of thing.) Here's my understanding of the time line on all of this. 1. Originally, our files were all plain text and we just included them in the email message body. The ~r command in Kurt Shoen's Mail program was typical. There was no name for this, we were just emailing files. 2. In 1980, I wrote uuencode. It's stated purpose was to "encode a binary file for transmission by email". I didn't use the term "attachment". It became part of 4.0BSD and later systems, and was widely used. 3. In 1985, Lotus created cc:Mail. It eventually included attachments, using a file store method. When they added an SMTP gateway later, it used uuencode as the format. I believe cc:Mail first used the term "attachment". 4. Microsoft did the same thing with MS Mail somewhat later, possibly in the 1990s. It also used uuencode in the SMTP gateway. 5. In 1992, Nathaniel Borenstein and Ned Freed invented MIME. It had a different (and IMHO much better) way to send attachments, and it became an Internet Standard sometime later, possibly in 1996. What do you all think? Mary Ann

I know very little of 4.x, but I did write a V6 DZ driver, back in the Cenozoic or some such time period... :-) Looking at the 4.3Tahoe (which particular 4.3 version is in question here, anyway?) DZ driver: http://minnie.tuhs.org/cgi-bin/utree.pl?file=4.3BSD-Tahoe/usr/src/sys/vaxub… I find it hard (without further digging) to figure out how it gets from where it should discover carrier has gone away (in dzrint(), from dztimer()) to the rest of the system; they have added some linesw[] thing I don't know about. Looking at the 4.2 driver: http://minnie.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/vaxuba/dz.c it seems (in the same routine) to do the right thing: gsignal(tp->t_pgrp, SIGHUP); so in that version, it's sending a SIGHUP to the whole pgroup when the carrier goes away - which should be the right thing.

The "lessor" technology wins over "better" technology because it's good enough. I'm curious for the Banks, in your experience - which were the UNIX vendors that were pushing 9-figure UNIX boxes. I'll guess, IBM was one of them. Maybe NCR. What HP, Sun, DEC in that bundle? > Linux is not Unix, and runs on cheap tin. > I believe that the point you are making is that "white box" PC's running a UNIX-like system - aka Linux could comes pretty close to doing what the highly touted AIX, NCR et al were doing and were "good enough" to get the job done. And that's not a statement about UNIX as much as a statement about, the WINTEL ecosystem, that Linux sat on top of and did an extremely impressive job of utilizing.

4.3BSD help: getty ignoring modem status

by Warren Toomey

Hi all, over on the uucp project we are struggling with a problem. If a user is logged in with telnet, and they disconnect the telnet session, their shell hangs around. The next person that telnets in gets the shell. SimH, with the -a -m flags on a simulated DZ line, has these modem flags: Telnet connected: Modem Bits: DTR RTS DCD CTS DSR Telnet disconnected: Modem Bits: DTR RTS DSR So, DCD and CTS are being dropped, but getty (or something) isn't responding and (presumably) sending a HUP signal to the shell. Is there anybody with some modem or getty knowledge that can help? Thanks, Warren

Re: [TUHS] who invented the email attachment?

by Doug McIlroy

> Should I make a claim to be the inventor of the email attachment? uuencode was critical to attaching arbitrary files, and I am sure one can find emails with uuencoded bits in them that read, "please find attached ...". But they would have said the same thing if what was being sent was source code. So attachment in that sense obviously predated uuencode. But to identify that kind of attachment with what mean by the word today is like identifying cat with tar. Doug

VAX SysVr2: tape /dev entries missing

by Cory Smelosky

All, Seems my SysVR2 simulation instance has at one point or another lost its /dev/mt/* and /dev/rmt/* device entries. Is there a script anywhere to regenerate these, or does anyone know the major/minor off hand for the SIMH TS device? -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

pathalias and sendmail experience?

by Warren Toomey

I know it's a long shot. Does anybody remember how to use the output of pathalias in sendmail.cf? Specifically, we have set up 4.3BSD with uucp-only e-mail, and we have a map file which pathalias digests and outputs fine. I can't find any useful documentation on putting this output into sendmail. There's part of a book in Google books, but two pages are hidden. I also threw out my old bat book ages ago. I have a PDF of Sendmail_4th_Edition_Oct_2007.pdf but it doesn't mention pathalias. Thanks in advance! Warren
