Passwords (Part 1)
by Stan Reichardt

Passwords are the magic words that let authorized users work on computers while keeping others out. But, really, "Part One"!? Just how much can be said about this subject?

Well, Stan likes to make a lot of slides. He roughed out about 30 slides a few months back and took up two full hours defending them before the Hazelwood Linux Users Group meeting. It may have been that he had put something interesting together. Nobody fell asleep and everybody learned something that they didn't know before.

You can expect a somewhat structured ramble through the wonderful world surrounding the front door key to Unix security. Nothing highly complex, yet worth discussion. Too much to cover in one tutorial session but interesting enough to continue next month.

We suspect that Stan Reichardt has some level of education, that he is licensed to drive his pickup truck, and that his employment has often been doing things other than his job title.

With a twinkle in his eye he recounts contract work with the US Post Office and Full Time active duty with the US Army Reserve. A life time member of the NRA that seldom shoots anymore, he is quite proud of a marksmanship trophy he got in 1990. The only other thing he is personally proud of from his military service is a bourne shell script application he wrote during his last two months with the US Army Reserve Command in Atlanta.

He is too cheap for the latest technical gadgets and his devotion to the VIM text editor (a "vi" emulation) is quite strong. For the last four years his personal choice of Operating Systems has been RedHat Linux.

His philosophy of life is that even though Y2K was a let down, similar opportunities happen all the time. Ask about his kitchen.

Stan was the volunteer SLUUG newsletter editor from Feb 1999 to Feb 2001. He has given various SLUUG tutorials and presentations. He acted as the "Beach Master" co-ordinator during the March 2001 St. Louis Linux Install-Fest. Currently he is the "Dictator for Life" heading up the Hazelwood Linux Users Group for "newbies" and he constantly attends our SLUUG Steering Committee meetings.

Check out Stan's personal web page at for a glimpse of his subtle sense of humor about vacations and near death. Questions and comments are welcome. Contact Stan Reichardt via email to or by phone at 314-298-1183.


Open Source Software: Ready for Prime Time?
by Dr. Myles Bogner, Asynchrony Solutions

With the successes of the Linux operating system and Apache web server, many IT executives today are beginning to leverage Open Source software. A major question prevails: how far can open source software take my organization?

This talk gives a brief overview of the Open Source movement. It then describes how to build an e-commerce web application using entirely open source software. Technologies utilized include Linux, Java, and XML.

Dr. Myles Bogner is Vice President of Research and Development for Asynchrony Solutions, Inc. He has extensive experience designing and realizing "smart" e-commerce and artificial intelligence software. Myles has developed leading edge solutions (primarily in Java) for venture-backed clients, medium and large sized corporations, and government agencies. He is an excellent leader in task management and has a refereed publications record. Myles is a vibrant instructor and continues to give invited talks. He has been a key team member of several interdisciplinary teams.

Myles received both his Master's and Ph.D. in computer science from the University of Memphis in a stellar three years after his B.S. in Computer Science from Rhodes College.

Ideas, questions and suggestions are welcome; please contact Christine Wanta (

Next St. Louis Linux Users Group Meeting Is August 16

Presentation: Jabber - Instant Messaging And Beyond
by Matthew Porter

Over the past few years, instant messaging (IM) has grown from a small niche market to the latest "must-have" technology. While IM competition between the big companies like Microsoft, Yahoo! and America Online has grown quite fierce, the open source community has remained strangely quiet. Without the open source community pushing for a standardization of IM protocol, the numerous competitors have kept their developments highly proprietary. While recent developments have prodded key players to pay lip service to standardization, the fruits of these efforts remain to be seen. Without a major open source project to uphold the standards and promote cooperation, users are left to the whims of large, faceless companies, interoperability flounders and outside development is non-existent.

Jabber is a completely open source, cross platform, feature rich, developer friendly, standards compliant IM platform. By upholding the standards of groups such as the IETF IMPP group, as well as creating a "translation" system between IM networks, Jabber promotes increased progress and frees users from negotiating which platform to use so they can focus on the point of IM: communication.

Matthew Porter is a graduate of Saint Louis Univeristy - Parks College. He has a Bachelors of Science in Computer Science and is planning to return for a Masters in Computer Science in the near-term future. Matthew is currently a Java architect and software developer at Demand Management, Inc. where he is working with a talented team to build the company's next-generation product. When not coding, Matthew can be found driving his 1969 Ford Mustang Mach I.

Meetings of the St. Louis Linux User Group (LUG) are held from 7:00 PM to 9:00 PM every THIRD THURSDAY of each month. Location: Indian Trails Branch - Saint Louis County Library. Meetings are free and open to everyone. Refer to for details and maps.

BBS Happenings

by Mike Knight

Several projects are in progress to improve SLUUG's computer systems, also known as the BBS. Work should be completed within a couple of months.

Configuration of a new mail server (i.e. a replacement for michelob) has started. Major new features include: 12GB of disk space vs. 3.5GB, 1GB memory vs. 64MB, a processor that is 3 times faster, and AIX 5L with many GNU utilities and Linux "application compatability".

A new Xyplex terminal server, for dial-up access, is now being tested. The main enhancement is a later release of the software which should further improve reliability. It will also provide the base for future security enhancements.

Account payments are now due for renewal. Emails will be sent out soon. Please make plans to pay as soon as you can. Payments may be made by mail, or at any regular meeting, and may be by check, credit card, or cash. Please contact Gary Meyer ( for questions about BBS billing or to sign up for an account.

If you wish to help with the BBS or the upgrades, please contact Mike Knight.

Biotech Follow-up

At the July SLUUG general meeting, Robert Citek gave a presentation on genomic research and his work at Washington University maintaining their high-performance computing cluster. The presentation was well-received, and many people were eager to learn more about the topic. Robert posted these URLs, some of which he mentioned during his presentation, and some of which provide additional information.

Annual Linux Showcase
