Name That Command - Stan Reichardt


For our tenth aniversary celebration and in lieu of a regular tutorial we will have a little fun. A little competition to test your Unix knowlege. Show off your brain cells and win a book from our end of day inventory!


Stan Reichardt is the volunteer Editor for The UNIX®CRONicle, the Official Publication of the STL!/unix/usr/group, i.e., the St. Louis Unix User's Group newsletter.

Stan has been using Linux for several years. He started out years ago coding COBOL on a national WANG VS-100 network. Over the years he has been known to administer various Unix/Novell/LAN systems and support desktop PC users. He tolerates main frames and would like to avoid Micro$oft in all forms. He provides 24/7 PC and Internet support to family and friends. Contributing his point of view to the SLUUG steering committee and to the SLUUG UNIX® CRONicle newsletter are secondary to his fascination with books and Linux. He loves his wife and son. He tolerates their dog.

Oct 1999 presentation on "What is an IP Address and Internet Addressing",
Jul 1999 presentation on "Learning VI Editing Commands" and his
Mar 1999 tutorial was on "Running the Satan Security Tool under Linux".

Guru Gathering

Smoke and Mirrors in The Guru's Corner - Rich Seible


This month a small group of those that are bored with the tutorials will meet in the secondary room, behind the main presentation area. Attendance will not be by invitation; but, lurkers and wantabees will be embarassed and urged to leave. Subject matter will be refereed by Rich Seibel.

Suspenders and pocket protector optional. Bring your slide rules.

Do you have what it takes to run with the Guru? A book will be awarded from the end of day inventory.


Rich Seibel is a consultant for Advanced Resources Inc. Rich was trained as an electrical engineer at Purdue University in 1966. He started out maintaining computers 25 years ago and moved into software and tracking technology. He is currently developing software for client server systems.

He has been a SLUUG board member and steering committee member in the past and has been doing tutorials for the Unix Users Group for quite a few years. Currently he is the organization's Secretary and general recorder.

His July 1999 tutorial was on "The History of Editors" and was a co-presentor in June 1999 of "The Micro$oft Anti-Trust Case."

Please contact Rich Seibel by sending if you have suggestions for this experiment.


Secure Shell by Dr. Stephen Blythe


"How Secure Shell Protects Remote Logins,"
or "How to Publicly Broadcast Your Password to everyone on the WWW by Using Telnet"

This presentation will introduce the advantages of using secure shell for remote access to computer systems. A discussion of how previous methods (i.e. telnet) work and how they are inherently insecure will be given. Since these methods are insecure, the addition of encryption will be discussed along with the drawbacks of basic (one key) encryption. Public/private key encryption will be introduced, as used by secure shell. Lastly, a brief discussion of some simple secure shell usage will be given.

Dr. Blythe earned the BS degree in Computer & Information Sciences from the University of Delaware in 1990. He worked in the MIS field for a little over one year before attending graduate school at Rensselaer Polytechnic Institute (Troy, NY), where he earned an MS in Computer Science in 1993 and a PhD in Computer Science in 1997.

He is currently an Assistant Professor of Computer Science in the Computer Science Department at Parks College of Engineering and Aviation at St. Louis University, where he is currently honored as the "Parks College Outstanding Faculty of the Year".

Results of each question on our OPTIONAL survey/questionaire:

1. Linux SIG Topic: Linux Certification by Rod Hauser

2. Psychological Assessment of Presenter.

3. I think Linux certification is:


Lots of new faces with new user questions. About half of the crowd had not been to the previous SIG meeting. Judging from the questions asked, they would have gotten a lot out of it.

Using the attendance sheets to draw for a book at end of meeting might get much better response.

Bad projector display dampened the audience.


Putting a computer in front of a child and expecting it to teach him is like putting a book under his pillow, only more expensive. -- Anon.

A Brief History of SLUUG, ITEC, and O'Reilly submitted by Dave Mills

SLUUG started its relationship both with ITEC and O'Reilly & Associates (publishers of computer books since 1985) in early 1991, and first participated at the ITEC Computer show in May 91. Because we were not for profit, we obtained a no-cost booth and provided our own booth furniture - two tables with neither carpet nor chairs.

Our presentations then were simple, (1) WHY UNIX? (2) HOW YOU CAN UTILIZE UNIX IN YOUR BUSINESS, and (3) UNIX OFFICE AUTOMATION (if I remember correctly). Enthusiasm ran high as we launched these two new endeavors - ITEC, and our business relationship with O'Reilly. We were a young group. Our membership was growing. Exciting things were happening.

In successive years, we built on our early experiences. We polished and improved our program and procedures, planned more sophisticated presentation topics, paid transportation costs for out of town speakers (often O'Reilly authors), and usually received TWO free booths for all our volunteers and book displays. O'Reilly provided free freight on book shipments. We were also required to pay for the very expensive booth furniture as the "commercial" booths did - the book sale profits usually just about covered our expenses.

The effort that was required to make each show a success increased, but as more SLUUG members participated and ITEC attendance grew, the effort seemed to be very worthwhile. Enthusiasm remained high as volunteers provided the help needed to make our participation of the show a success.

In recent years, the number of new volunteers has decreased, leaving many of the same SLUUG members to manage and coordinate the show. Predictably, some of the enthusiasm has faded. Whether or not SLUUG will continue to participate in ITEC depends, as always, on the needs, opinions, and voluntarism of the members.

SLUUG Participation at ITEC? submitted by Dave Mills

It is time for us to decide if SLUUG will participate at ITEC (Information Technology Expositions & Conferences) again this year. This decision is critical to the group. The ITEC event has, since 1991, become our principle interaction with the St. Louis area public and business community. Members, please guide us in this decision!

(See companion article entitled A Brief History of SLUUG, ITEC, and O'Reilly.)

The objectives of participation are:

  • promotion of open systems and UNIX within the community,
  • exposure of our group to the community itself,
  • increased membership, and revenue from book sales.

    There is no downside to participating as long as we effectively meet the objectives. However, the members must support ITEC, and provide the effort required to meet the objectives. Support appears to have been waning in recent years.

    Are we interested in participating again this year? Do we have the resources required to make our participation a success? Will we retain our relationship with O'Reilly & Associates if we do not participate? Are there more effective ways to promote open systems? What are your ideas suggestions?

    Many of the members realize that our inventory of O'Reilly books is the best in St. Louis (perhaps the best in the U.S.?). We have truly been fortunate to have O'Reilly as a business partner. However, because our ITEC sales run about 40% of our annual book sales, we face the realization that our partnership might easily be terminated if we discontinue selling the books at ITEC -- unless we develop other means of increasing sales.

    Please email your thoughts, availability, and capacity to help by by 1/15/2000. We must make the ITEC decision at the next Steering Committee Meeting.

    ITEC Volunteer Duties Overview: submitted by Dave Mills & Gary Meyer

    If we do participate at ITEC, volunteers will be needed to manage, coordinate, and administer the SLUUG effort at ITEC, as well as work in the booth. There are several ways to organize our program so that no one person is over burdened, but one suggestion would be to have a central manager with 2 or 3 area managers. Area managers could be (1) Presentation Manager, (2) Booth Manager, (3) Book Sales Manager, and (4) Linux Install-fest Manager.

    Following are a sample of duties required for ITEC, based on the area manager concept.

    (1) Central Manager - ASM (American Show Management) contact, responsible for overall ITEC coordination, chairs and coordinates group meetings with area managers, develops show theme, negotiates and schedules booth(s) and presentation rooms, attend kickoff breakfast, orders and distributes tickets

    (2) Presentation Manager - develops two to four presentations, finds, schedules, and coordinates presenters and presentations, advertises presentations, takes attendance at presentations, may develop contests, prizes

    (3) Booth Manager - determines furniture needs orders furniture, obtain volunteer name tags, coordinates booth set-up and tear-down, recruits members to man booth, develop forms for new members, provide extra copies of past editions of the Cronicle, SLUUG brochures, other handouts, may develop contests, prizes

    (4) Book Sales Manager - determines book order, orders books, develops pricing, sales procedures, sales training materials, delivers and installs books and displays, de-installs books and displays after show ends. Picks up books, assists in preparing excess book returns to O'Reilly.

    (5) Booth Personnel - describes SLUUG to attendees, promotes open systems, and UNIX, sells books, works under direction of Booth Manager

    (6) Linux Install Fest - its been suggested that we might want to do an install-fest. Perhaps we would do this instead of the presentations. Since this is an event of timely interest, we may attract much attention! It would certainly take work in advance to organize so it needs a manager and volunteers.

    Are you interested in our continued participation at ITEC? Do you have ideas about other formats we might use to promote open systems? Most importantly, what resources can YOU provide for either scenario? Can you be the Central Manager or an Area Manager? We need your input to the above questions. Our group lives ONLY through the participation of its members.

    Please email your thoughts, availability, and capacity to help by by 1/15/2000. We must make the ITEC decision at the next Steering Committee Meeting.
