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 High 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. Web Resources: -------------- 1.

High Availability Cluster Checklist http://www2.linuxjournal.com/cgi-bin/frames.pl/lj-issues/issue80/4344.html 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 clusters. 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. ** Mission Critical Linux will be sponsoring the food service at ** this month's Unigroup meeting!

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.

PRIOR MEETING ------------- 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 examples. 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).
