Robert Citek works for the Office of Technology Alliances at the University of California, Irvine, see where he gets to read and track all the cool inventions coming from the University. Purely for fun, he also remotely administers a cluster of Linux and Windows machines in Irvine from St. Louis.

Ideas about this discussion are welcome; please send

Guru Gathering

Spontaneous Subjects - Hosted by Rich Seibel

This Gathering of Gurus (GoG) is an informal discussion group of people with similar degrees of experience and common interests for open discussion. They would rather talk with peers than sit quietly and listen to the tutorial. Anyone may attend, and discussion is encouraged.

Ideas for future discussions are welcomed; please send

  1. Mike King is knee deep into web pages. So much so that he had even taught about them at the St. Louis Community College. Mike writes CGI, PHP and HTML in his sleep.

  2. Ed Wehner works for MEMC. They keep sending him to Japan on business. He knows lots of Japanese. Ed can order Japanese beer in his sleep.

  3. Craig Buchek just got back from a personal trip to Japan. As soon as he recovers from jet lag he plans to re-compile the latest Linux development kernel. For his day job, he's a consultant and is currently writing training material for Wave Technologies Intl., Inc. Craig can compile Linux in his sleep, but he's usually awake when he drinks beer.

Next Linux SIG Meeting Is 15 June

Focus on Linux Security - by Matthew Porter


From shadow passwords to encryption to malicious code, an indepth guide to both Linux innate mechanisms and the tools available to security professionals (and hackers) will be detailed. Furthermore, the presentation will briefly cover some of the most notable security holes and the means to protect one's systems against them.

Ideas about this discussion are welcome; please send

We must point out that the LINUX SIG meeting is THIS WEEK (i.e. the 15th) and not the following week. There was some confusion because the 1st of this month fell on Thursday.

On a positive note Matthew Porter has volunteered to be at the Library the following Thursday as well because we accidentally published the wrong date in some ITEC handouts. If anyone wants to join him there in case some new attendees do show up, he will appreciate the company.

ITEC Volunteers Carry the load!
by Gary Meyer

We are still cleaning up the details from our participation in this year's ITEC (Information Technology Expositions and Conferences) Expo 2000. It is always heartening and amazing how so many of our members volunteer their time and efforts to get our Users' Group the needed exposure at this event.

An immediate "thank you" to all the volunteers. More on this next month.

The ITEC Committee looks forward to hearing from you.

Members can send for details.

Thanks to Matthew Feldt
by Gary Meyer

Matthew Feldt is moving to Cleveland and is leaving the SLUUG Linux SIG Chair.

Although we would greatly appreciate his continued participation his absence means he must step out of his duties as Chairperson.

In July 1995, the 1st meeting of the Linux Special Interest Group (SIG) was held. Matthew was the 1st presenter and has been the guiding influence of the St. Louis Unix User's Group (SLUUG) Linux SIG since its inception. Matthew did so much of the work on his own... doing presentations, organizing other presenters, soliciting give-aways...he was really wearing multiple hats and we too seldom thanked him.

Before starting the SLUUG Linux SIG, Matthew had been active in the leadership of the overall Users' Group and a presenter at the Wednesday nite meetings.

So I'm sure everyone in the Users' Group offers Matthew a "BIG THANK YOU" for his years of outstanding contributions. If Matthew makes it to this month's meetings, please express your appreciation in person.

Matthew will still be working for his current employer, First Star, and hopefully he will attend our meetings and other events when they have him come to St. Louis. Until then, we hope he stays in touch online.

THANKS Matthew!!!

Future of Linux SIG
by Gary Meyer

We have had at least 4 people volunteering to take over some/all of Matthew's duties and then some. The steering committee is talking to all of them and will shortly be announcing the new organization of the SLUUG Linux SIG.

We thank everyone who has expressed interest and concern for the future of our Linux SIG. We remind everyone that many hands make lite work and we do need more people to volunteer for various and different roles to continue to improve the organization.


Following submitted by Mike King:

Guess which operating system they are talking about...

"There were no new memory utilization issues this month, though there are several servers that continue to experience slow memory leaks. This has been reported to the Shared Server support team in the past and in most cases is not a critical issue due to the frequency with which servers are rebooted."
--- Chevron New Orleans IT Service Center

Short Subjects Wanted
by Gary Meyer

We need some short subjects!

Have you had an idea that you might speak on a topic but thought that there wasn't enuff material or that it would take too long to prepare a quality presentation?


We have frequently noted that we too often push into longer meetings. Short topics are what we need! The group is eager to get a little starting material and then flesh out the discussion with questions and comments from the entire group.

The word "seminar" comes from a greek root meaning "drinking session". The concept was that people would make comments in a social atmosphere not as an "expert" in the field but as a peer presenting his view and soliciting the views of others.

You don't need to be an expert. Just get us started on a topic with a few points, insites, or questions.

If you you think your topic is VERY short...we can do 2 presentations on different topics that nite.

Call for Comparison Panelists
by Gary Meyer

We have an idea for 3 months of presentations. We need some volunteer panelists to take part.

  1. We want to compare different UNIX releases. Since almost none of us is well versed in every version, we are looking for panelists who can at least reflect on their experiences with 2 different versions. EX. Solaris and AIX. or, HP-UX and SCO. If you have experience on more than 2, great!

    The idea would be for each panelist to present what most impressed him about the differences (similarities) between the 2 or 3 or... that he/she is familiar with. For example; management tools such as SMIT vs SAM, file systems (journalization, NFS,...), or installation options and scripts.

    After a Panelist gives his views, other panelist may take the opportunity to comment on the same points referring to versions they are familiar with (i.e. the 1st presenter speaks about file system auto-mounts in Solaris and HP-UX and someone else follows up by adding how AIX handles the same issues).

    We suspect each panelist would need to do little preparation. We would try to share each panelists points in advance so other panelist can reflect in advance.

  2. We want to do the same thing but tighten the focus to "Free UNIXes". I.E. Linux, SCO, Solaris, FreeBSD, OpenBSD,... We'll define "free" as being anything that allows for non-commercial or private users to use without a fee.

  3. The same as above but a tighter focus yet to Linux variants only. Ex. Mandrake vs RedHat vs SuSe vs Debian vs ...

Please say you can be a panelist for any of these events!

We also would love for 3 people to volunteer to be the co-ordinator of these 3 projects. The co-ordinator would keep track of the volunteers and circulate the potential topic points between them and suggest a date for their presentation.

For more information members can send for details.

UCITA: Does it impact you?

A new wind may sweep the software industry. More important than any Microsoft anti-trust lawsuit, the Uniform Computer Information Transactions Act (UCITA) may rewrite the way vendor software is sold and supported. This is being propagated in legislatures across all 50 states, one at a time. When opponents include Consumers Union, the Association for Computing Machinery, the American Library Association, and the Electronic Frontier Foundation, it may be worth looking into.

What does the UCITA do?

- Allows license terms to be be hidden until after software is purchased.
- Allows license terms to be changed by simply posting them on a web site.
- Reduces warranty protection and the right to sue vendors that produce code that is unusable.
- Allows licenses to bar you from publishing your complaints.
- Allows vendors to monitor use of their products and remotely disable software.
- Allows vendors to prohibit selling or giving away used software.
- Gives software developers the power to prohibit reverse engineering of file formats and protocols.
- May make individual and amateur programmers more liable than large companies.
