  Lab-anon?  Is that that support group for those who want to kick their
  technical and scientfic habits?

What is the yes program?

Try "man yes" to see.

I just did "man yes" on my Linux system.  It says:

NAME
       yes - output a string repeatedly until killed
SYNOPSIS
       yes [OPTION]... [STRING]...
DESCRIPTION
       Repeatedly  output a line with all specified STRING(s), or `y'.
       --help display this help and exit
       --version output version information and exit
SEE ALSO
       The full documentation for yes is maintained as a  Texinfo
       manual.   If  the  info  and  yes  programs  are  properly
       installed at your site, the command
              info yes
       should give you access to the complete manual.

Note that the "full documentation" in "info" is shorter than the
instructions to look in "info" for full documentation.  Gnu software is
a wonderful thing, but sometimes I think the authors would benefit from
electroshock treatments.

Well, I'd expect a silly program to have silly documentation.

(The last paragraph of the man page was probably auto-generated
from a template that's used for all GNU software.  Major GNU
programs do tend to have more extensive info documentation than
man documentation.)

Any ideas why the queue to log in to Grex has soared this week?

   M-Net's being down? I think thats it.  I've seen a slew of new logins and I
   kinda
get the feeling that we're handing more mail than we usually do, too.

I thought of the M-net outage too, but the queue surge has just been in 
the last couple of days.

Is there any legitimate use for the "yes" command (other than for 
filling a disk)?

Long long ago, some Unix admins would flick a switch that made "rm" ask "do
you really want to delete this file?" everytime you did "rm file".  This was
really annoying because there was then no way to turn the prompt off, so when
you did "rm *" in a directory with 1000 files, you had to type "y" 1000 times.
So someone wrote "yes".  "yes | rm *" worked.  These days you can turn on the
prompt in "rm" without making it impossible to turn off, so I haven't seen
anyone do "yes | rm *" for about 17 years now.  I presume "yes" is still there
for backwards compatibility.  Lots of unix systems don't have it anymore.

  Basically it's a program to pipe stupid answers to programs that
  ask stupid questions..  I've used it on occasion on certain installer
  programs when I knew in advance that everything which was going to be
  asked would take the same answer.

When I tried to retrieve my mail just now here is what happened:

Ok: !mail

/tmp: write failed, file system is full
panic: Message temporary file corrupted

/tmp: write failed, file system is full
terminated: IOT

Should I panic?  Could someone check this out?  Thanx!

when I logged in just now, it took my login and passwd, started to log me in
and then before giving me a prompt it went back to the login prompt complete
with beep and I had to log in again.  In light of recent events should I be
worried about another passwd sniffer?

Dave:  Sounds like /tmp filled up.  This shouldn't have caused you to
lose any mail.

Chris:  I don't know what caused that, but it wouldn't have been a
password sniffer.  I think those just monitor packets on the network,
without interupting their flow.  A password sniffer would normally not
be noticable.

Yeah, bad choice of word, I was thinking more of a passwd "grabber".

Trojan horse, that pretends to be the login program, but instead grabs
your password, saves it, prints a "password incorrect" message, and
drops you to the real login prompt so you'll never guess what happened.

I haven't heard of this being done on a modern Unix system.  Normally
telnetd won't allocate a pseudo-tty to a new person connecting in if
there are still any processes open on it, so for as long as the Trojan
hangs around, nobody else would connect to that pseudo tty so nothing
would happen.  You'd probably have to do something clever like exploit a
race condition to get the Trojan in on a pseudotty that was actually
connected to someone.  I don't know enough about this stuff to say it
can't be done, but I'd be surprised.

An easier way: modify .login to mimic the prompt a second time.  An easy
way to promulgate the modified .login is with a message like "for a great
time, telnet to trojan-source.com and login as sucker with the password
gotcha."

        I've seen programs that closely mimic the NT login screen and xlockmore
being used to troll for student passwords (and occsasionally, for the bold,
lab administrator passwords), before.

Is this why you're supposed to hit Ctrl-Alt-Del before logging into NT?

What is the proper procedure for someone who changed their password but
apparently typed it wrong to obtain the correct spelling?  Our friend read
the book and typed in trouble at the login prompt, Wednesday, and says nobody
has gotten back to her to help, or if they have, they emailed and she cannot
read her mail.  (I emailed staff to send me her password or phone her).

Does anyone else have to dial three times on average to connect rather than
getting 'no carrier'?
