Layer 3 "switch" is marketing drivel for "really fast" (typically
hardware) router. If it sinks like a duck

Layer 3 switch = Router (IMHO) esp in today's world. All layer 3 switches
that are routing packets using layer 3 addresses must follow RFC1812 etc.

Layer 2 switch != Router. They commonly do Ethernet stuff.

It should also not propagate broadcast IP packets (subnet or all 1's).
(Any other hard requirements?)

A router decrements the IP TTL field.

Re: Mailing list software

my impression is that postfix can run up to an order of magnitude greater 
message loads than regular sendmail.

Mailing list software

[Henning G. Schulzrinne]

We're running a number of IETF mailing lists on our server here at
Columbia. Some of the lists have gotten a bit larger and more popular
than we anticipated; sendmail is groaning. Any suggestions for alternate
delivery software (for Solaris and/or Linux)? (Since this is somewhat
off-topic, please send me responses privately and I'll summarize if
there's interest.)

IETF PGP Key Signing Party for San Diego

[tytso]

Once again, we will be holding a PGP Key signing party at the IETF
meeting in Minneapolis.  We have been scheduled to meet at 10:30pm on
the evening of Wednesday, March 21, 2001. The procedure we will use is
the following:

o People who wish to participate should email an ASCII extract of their
  PGP public key to <[EMAIL PROTECTED]> by noon on Wednesday, March 21,
  2001. Please include a subject line of "IETF PGP KEY", and please
  avoid MIME-encrypting your e-mail.  (I will be running the entire mail
  folder file through PGP, and PGP-keys that are base-64 encoded will
  get ignored unless I take manual action to fix things.  I will try do
  the manual fixup, but I make no guarantees about catching all of them.)

  The method of generating the ASCII extract under Unix is:

pgp -kxa my_email_address mykey.asc (pgp 2.6.2)
pgpk -xa my_email_address > mykey.asc   (pgp 5.x)
gpg --export -a my_email_address > mykey.asc(gpg)

  If you're using Windows or Macintosh, hopefully it will be Intuitively
  Obvious (tm) using the GUI interface how to generate an ASCII armored
  key that begins "-BEGIN PGP PUBLIC KEY BLOCK-".
  

o By 6pm on Wednesday, you will be able to fetch complete key ring
  from the following URL with all of the keys that were submitted:

http://web.mit.edu/tytso/www/ietf.pgp

o At 10:30pm, come prepared with the PGP Key fingerprint of your PGP
  public key; we will have handouts with all of the key fingerprints of
  the keys that people have mailed in.

o In turn, readers at the front of the room will recite people's keys;
  as your key fingerprint is read, stand up, and at the end of reading 
  of your PGP key fingerprint, acknowledge that the fingerprint as read
  was correct.

o Later that evening, or perhaps when you get home, you can sign the
  keys corresponding to the fingerprints which you were able to verify
  on the handout; note that it is advisable that you only sign keys of
  people when you have personal knowledge that the person who stood up
  during the reading of his/her fingerprint really is the person which
  he/she claimed to be.

o Submit the keys you have signed to the PGP keyservers. A good one to
  use is the one at MIT: simply send mail containing the ascii armored
  version of your PGP public key to <[EMAIL PROTECTED]>.

Note that you don't have to have a laptop with you; if you don't have
any locally trusted computing resources during the key signing party, 
you can make notes on the handout, and then take the handout home and
sign the keys later.

This is exactly the problem: I could not find any
Leslie-Lamport-quality-HOWTO-document for nroff.

First of all, I define "dino technology" as
something where the average age of its producers 
(not just users) constantly increases.

Well, an eye for an eye, a rhetorical question 
for a rhetorical one :-).
I am just wondering what you are going to do with
your private video tapes. Keep them as is, or
transfer them to VCDs, or transfer them to DVDs?
Same question for QIC-150s, Reel tapes, etc.
