     Topic:  Linux Clustering: Fault Tolerant High Availability Clusters

   Speaker:  Nick Carr, Director of Professional Services
             Mission Critical Linux

   Meeting Introduction:

   We have a couple of things planned for this month's meeting:

   - Unigroup Board of Director Elections
   - Discussion/War Stories concerning the Northpoint DSL Collapse
   - Part 2 of a series of meetings on Linux Clustering

   Unigroup Board of Director Elections:

   Unigroup Members are welcome to volunteer to be on the Board of
   Directors of Unigroup of New York, Inc.  Please Email the board at
   uniboard@unigroup.org if you are interested in getting on the ballot.
   The Unigroup Board holds a board meeting typically once per month in
   Downtown NYC and performs other correspondence via Email and Telephone.
   The Board plans, prepares for, and runs the meetings, finds speakers
   and giveaways for the meetings, and performs other tasks which keep
   the group alive.  Unigroup is a volunteer organization and we need
   your help!

   DSL War Stories:
   Did your Northpoint DSL go down in April?  Did your DSL circuit remain
   up but there simply was no Internet on it?  Did you have a backup plan
   for Internet Connectivity such as dial backup?  Did you know your DSL
   Router probably has built-in automatic dial backup and you could have
   been prepared?  If you had automatic dial-backup fully tested and
   working prior to the DSL going down, when it did go down, and the
   router automatically switched to backup, did you find that you now had
   new routing problems preventing Internet connectivity?  Are you dealing
   with an ISP who offers dial-backup service?  Did your provider drop the
   Reverse DNS for the IP range configured in your dial-backup router and
   firewall (without notice) such that sendmail took a full 60 seconds to
   start up?  Did you deal with a provider who's idea of dial-backup is a
   single-user windows-style pop account which uses a single pop box to
   route in-bound mail to hundreds of people spread across the country in a
   handful remote offices?  Did that same provider refuse to accept your
   out-bound SMTP traffic even though you were using one of their dial-up
   connections (login/password/their dynamic IP range), because they
   simply did not believe that you were you and that you were one of their
   customers?  Did they force a dynamic IP range on you such that you
   could no longer transmit SMTP to various sites such as AOL due to the
   DUL?  Did the entire Northpoint mess occupy so much of your time that
   you simply didn't have time to put together a special April Unigroup
   meeting (sorry about that)?
     ...can you tell? ...it wasn't fun!  I have a couple of personal
     of war stories to relate.  I hope some Unigroup members have a
     few of their own to discuss too.  The main goal of the discussion
     is what to have in place, what can and will go wrong, and what
     to watch out for.

  The Main Presentation:

  The March 2001 Unigroup meeting was on Linux Beowulf Clustering.  The
  May 2001 Unigroup meeting will be a followup meeting which will detail
  another aspect of Linux Clustering Technology: Fault Tolerant Highly
  Available Clusters.  Our speaker, Nick Carr of Mission Critical Linux,
  will discuss aspects of High Availability and how this type of
  clustering may be used on Beowulf Clusters to build a robust and fault
  tolerant clustering environment.  Mission Critical Linux's Convolo
  Cluster software is a high-availability cluster product for Linux which
  is based on the Open Source Kimberlite clustering technology.

   5. High Availability Cluster Checklist

  Description of Talk:

  This talk follows on from earlier presentations on Linux high performance,
  Beowulf-style clusters. It describes recent advances in the area of Linux
  high availability clusters. Designed for deployment in commercial
  environments using standard, unmodified applications these clusters have,
  in most respects, achieved parity with traditional Unix commercial-market

  The presentation will include a mid-level technical overview of high
  availability cluster technologies, describing the fundamental properties
  of these systems - including configuration details, primary algorithms,
  shared storage subsystems, and application implications.  The presentation
  will also cover clustering technologies that are actively being worked on
  by the Linux community - including distributed lock managers and cluster
  file systems.  The presentation is intended to be highly interactive,
  allowing attendees the maximum opportunity to learn about these
  interesting systems.

     55 Water Street is between Water Street & Front Streets at Old Slip...
     about 7 blocks south of Fulton St. and the South Street Seaport.
     Take 4 train to Bowling Green & Walk Due East;
     Take 2/3 trains to Wall Street, Walk East to Water St.
          then walk South 5 blocks;
     Take M/J trains to Broad St., Walk East to Water St.;
     Take N/R trains to Whitehall St., Walk North East to Water St.
     There is parking on the street (after 6:30-7pm) and there is a lot
          right in the building, entrance on Old Slip.
     Walking from Wall St., follow William St. south which bends around
          and leads you to Hanover Sq. and Old Slip is across Water Street.

  Room Location Specifics:
     Enter the building at Old Slip.  To get to the South Tower of the
     complex, you enter the building at Old Slip at the "North Tower"
     doors.  This entrance is is immediately to the right of the main
     entrance, towards Water Street... ie. Use the right-most side doors
     rather than walking straight ahead at the Old Slip entrance.
     Go past the guard's desk (mentioning you are heading for Unigroup,
     sometimes there is a sign-in) to the elevator bank and go to the 13th
     floor.  When you get to the 13th floor, follow the signs leading you
     to the meeting room.

     The signs will lead you from the elevator, through a set of doors
     (soda machine will be on your left), then past the cafeteria.  After
     the cafeteria, you see another "lobby" area.  Walk past the cash
     machines, make a left and look for a sign marking the meeting room.
     Conference Room C will be on your left.

     If you come very early, we may not have the signs in place yet, but
     hopefully these directions will get you to the meeting room.
     If you arrive before Unigroup Board Members, please be patient and
     wait for us to arrive.

   Please let us know about any other meeting topics that you may be
   interested in.  Potential speakers on Unix releated technology topics
   should contact the Unigroup board at uniboard@unigroup.org.



   Our thanks go to Jozef Skvarcek, Ph.D,, who gave us a great
   How-To presentation on Linux Beowulf Clustering.

   We learned about general clustering concepts, Beowulf specifics and
   related standards and programming APIs through the use of real life

   Our thanks also go to Andrew Flesch from TurboLinux who briefly
   spoke about TurboLinux EnFuzion.  TurboLinux provided various
   giveaways including EnFuzion CD-ROMs and T-Shirts.  We hope to
   have TurboLinux come back for a more formal presentation some time
   in the future.

   We also gave out our remaining copies of OpenLinux that we received
   from Caldera.  I think just about everyone at the meeting walked
   away with something nice!

   Speaking of prior meetings, we recently had a talk from Jeff Altman
   of the Kermit Project at Columbia University.  The Kermit Project Site
   http://www.kermit-project.org has announced that we've just past
   the 20th Anniversary of the first Kermit file transfer.  Its nice
   to see that some good things have made it for the long haul.
   The site also has announced new releases of Kermit-95 and C-Kermit.

   Do you realize that Unix is about 30 now (possibly 31+)?  The Unix
   time_t was based on 01-JAN-1971 (later changed to 01-JAN-1970).
