St. Louis Unix Users Group - Linux SIG (SLUUGLS)

Presentation: "Sharing Filesystems between Windows and UNIX using Samba" by Kevin Lafata

Kevin Lafata, a Lead Software Engineer at Enterprise Rent-A-Car, will discuss sharing filesystems between Windows and UNIX using Samba. Most of Kevin's work involves Windows programming with a focus on Intranet and Internet applications (not HTML). Kevin is a Computer Science graduate from the UM-St. Louis and has been attending the St. Louis Linux Users Group for the past eight months.

Kevin's presentation will cover several aspects of Samba, a utility that allows Windows clients to connect to directories on Unix servers. The presentation will cover system requirements, a brief overview of the binaries included with the package, how to configure Samba to share directories and security at share and user levels. Time permitting, Kevin will also cover using Samba to validate Windows 95 domain logins.

"Second Thoughts"

by Stan Reichardt

Frequently I open my mouth at the SLUUG and Linux SIG meetings. Maybe that's a good thing; but, sometimes I am wrong. I have been wrong at least twice, the time that I thought I was and then the time I realized that I wasn't. ;^)

Usually I bring up items that I think may be interesting; but, I don't always have all the facts that I would like to share. Hey, I never claimed to be perfect. The only experts I know have a job title that others consider as endowing them with omnipotent powers. (Is half the information all bad?)

A few months back, at the SLUUG general meeting I mentioned an interesting article in BYTE magazine on Windows NT security holes and couldn't remember the full reference. Anyway, it was in the November 1997 issue of BYTE, Volume 22, Number 11, page 81 article titled "Deja Vu All Over Again". I really like the subtitle "...holes that other OSes patched years ago." Many of the comparisons with NT's short comings are with UNIX. Every would be cracker in the country now has a nice blueprint. The experienced crackers may already be in the building using old keys. Still, everyone should read this one. You should be able to get it right off the rack at any public library extension.

Of note, anyone with the money and SERIOUSLY interested in Windows NT security probably shouldn't miss the USENIX tutorial to be given by Ric Farrow on 26 January in San Antonio TX. Ric Farrow's book on UNIX system security is a classic that provides outstanding insights and practical solutions. See for a description of mind stretching possiblities.

For the curious individual that asked at a prior Linux SIG meeting "what was the name of the Linux mascot" - the penguin's name is "TUX" as in "tuxedo".

At the last Linux SIG I asked the presenter from Caldera if they had made any significant market progress by providing a C2 security distribution of Linux. He disavowed any knowledge ( might have to shoot me... ).

In the dark recesses of my mind I thought that Caldera had been touting that they were able to provide such. Well, I can't find the basis for my delusion anywhere. Not even a reference trail on a number of Internet search sites ( like and ). Maybe I just imagined it. More likely it was some other firm and it was just vapor ware. Apologies for misinformation seem to be in order.

Well, enough is enough. I do get carried away.

St. Louis Java SIG

Mark Volkmann of Object Computing, Inc. will present RMI.

Remote Method Invocation (RMI) provides a mechanism for creating distributed Java applications. It is more robust than using sockets. It is easier and less expensive than using CORBA. This talk will present the benefits and issues associated with creating distributed applications. It will also discuss the mechanisms RMI employs to support distributed applications. Finally, a walkthough of example code will show how to utilize RMI.

Next meeting details:

  When:    Thursday, January 8, 1998, 6:30 PM
  Where:   Novell, Inc., 600 Emerson Road, Suite 203
  Topic:   Remote Method Invocation (RMI)

ACM, St. Louis Chapter

The Saint Louis Chapter of the Association for Computing Machinery (ACM) invites you to a presentation of "Associates & Wizards: Software That Models You and Your Problem" by Dr. Kirby Keller of Boeing St. Louis

When:  Monday, January 12, 1998
       Social & Dinner: 5:45 PM. Program: 6:30 - 7:45 PM
Where: Grones Cafeteria:  4409 Woodson Rd, 423-7880

Abstract: User hostile software is commonplace and needs no definition. User friendly software is less common and is characterized by a user interface and underlying problem model that the user can readily understand and manipulate.

An "Associate" system and, to a lesser extent, current PC "wizard" systems, not only provide this benign problem model, but also an active model of the user and the user's goals and tasks. Using this model, the wizard or associate system anticipates user needs and provides aid to the user in the form of information and automation as needed.

A software architecture and development approach for an associate system that was built as part of a United States Air Force (USAF) research program for a tactical aircraft is presented in a very listener friendly manner.

Biography: Dr. Keller is leader of the Intelligent Systems and Supportability Technology Research groups at Boeing St. Louis. He is a Senior Principal Technical Specialist there. (He notes that he's spent 23 wonderful years at Boeing St. Louis, formerly McDonnell Douglas Aerospace.)

Arrangements: Begin the cafeteria style dinner and social when you arrive. Dinner and FREE lecture are in the back room. Non-members are welcome. No registration. Bring a friend!

St. Louis Object Oriented SIG

Meeting Host: Insight Technology Group
Topic: Employing Meta-Modeling Patterns
Presenter: Tom Hill, Executive Vice President & Chief Technology Officer, Insight Technology Group

Tom will present structural meta-modeling as a technique to help manage the magnitude and complexity of large object-oriented applications. A meta-model is both a design pattern, and a repository for other design patterns. Insight has successfully applied this technique on multiple consulting engagements in industries such as telecommunications and catalog management. Tom's presentation explains the what, why, and how of meta-modeling, with a demonstration of a meta-modeling tool used by Insight.

Date:   Thursday, January 15th, 1998
Time:   4:30-6:30 p.m.
Place:  One City Place Drive
        St. Louis, MO  63141

Directions: From 270, take Olive east. At the fourth light, turn left on City Place Drive (between ProVisions and Amoco). Park in an unmarked space in the garage. The auditorium is on the lower level.

RESERVATIONS ARE REQUESTED (for planning purposes). Emailed responses are preferred. Please RSVP to:, or call Kim or Sue at (314)344-5007.

St. Louis User Interface Society

When: Wednesday, January 7, 1998, 7:00 - 9:00 PM
Where: Edward Jones Usability Center, Bldg 141 Progress Parkway, Maryland Heights, Missouri

"Overcoming Roadblocks to Usability" will be presented by Matt Johnson of Edward Jones. Matt will discuss the four cornerstones that helped make Usability standard practice for all software developed at Jones. Prior to the presentation, a brief tour of the Edward Jones Usability Center will be given. This tour will highlight the two usability testing suites and the focus group room.

We also have some time scheduled for a group discussion. If you have a topic you would like the group to discuss please let me know.

John Harris of Edward Jones will chair our meeting.

Directions: Take 270 to Dorsett road and go east. Take Dorsett to the first street, Progress Parkway, and turn right. You will see a 3-story Jones building on your right. Immediately after you pass that building, take a right onto American Industrial. Take that road around and turn left into the first parking lot you come to. This is the parking lot of the building the meeting is in (Bldg 141). There are 3 doors into this building (2 side doors and 1 front door) and they all require security access. Come to any one of the side doors and someone will be there to let you in.

Please consult the St. Louis User Interface Society web site for the latest and most recent meeting information, including the agenda and a map to Edward Jones.
