7:30 PM Presentation Resource Manager by Chad Bersche


Resource Manager by Chad Bersche, Sun

Solaris Resource Manager (TM), enables resource availability for users, groups, and enterprise applications. While many system management tools provide the means to _monitor_ the use of system resources, they typically lack the means to _control_ system resources. Solaris Resource Manager offers the ability to control and allocate CPU time, processes, virtual memory, connect time, and logins, and does so on a fine grained basis. Solaris Resource Manager provides a proactive means for controlling system resources, and thus guaranteeing service levels for various applications running on the same server.

Parts of this product are licensed from a 3rd party and apply to other versions of UNIX besides Solaris.

Chad Bersche is a Systems Engineer with Sun Microsystems, Inc. in St. Louis covering named accounts since 1997. He specializes in data warehouse systems, interoperability, clusters, and systems management. Chad has over 10 years experience in the IT industry, starting in 1987. He has held positions as a mainframe operator for Wal*Mart Stores and J.B. Hunt Transport, as well as acting as a Small Business Consultant and Customer Engineer for IBM.

Chad started with UNIX in 1989 where he was systems administrator for 200+ Sun workstations and servers at the University of Arkansas College of Engineering. Prior to Sun Microsystems, he worked in the Data Warehouse service line of Ernst & Young, LLP where he was responsible for the technical architecture and design of multi-terabyte data warehouse systems as well as system benchmarks and tuning efforts.

{ Editor's Note: While waiting for the "official" bio to arrived we considered using the following:

Chad Bersche of Sun is a really cool dude, a UNIX kind of guy. Friendly, knowledgable, and has never ( not ever ) heard a "dumb" question. You will feel all warm and fuzzy just listening to him answer all questions. }


Running the Satan Security Tool under Linux by Stan Reichardt

There is an open source network security auditing package called SATAN. The Security Administrator's Tool for Analyzing Networks (SATAN) was released onto the Internet in April 1995 along with as much media hype as was received by the notorious Michelangelo Virus. It was the first network security tool to get real attention in a world that was ignoring security.

As a freely available GUI tool it's arrival scared everyone out of denial. Security by obscurity was no longer safe. The bad guys already knew all the holes; so, why shouldn't the good guys have a tool to show them what to fix on their networks and how to fix it?

The SATAN package is old and not the best; but, it makes an excellent starting point for those new to network security. It is hopefully a "useful" tool, and one that's even fun to use. It runs on UNIX type OSs and will probably never be ported to NT (but, who cares). It does not compete with newer commercial and open source packages; but, for the price you might want to run it on your network at least once. If you don't, somebody else might.

The SATAN package has the following features:

* WWW browser Graphical User Interface

* identifies well known weaknesses and misconfigurations

* provides solutions to what if finds

* modular structure allows for extensions and improvements

* a repair tool for system administrators - not system crackers

This introductory tutorial discusses loading the infamous SATAN network security package on a Linux platform from the perspective of those new to the subject of network security.

This tutorial will provide an overview of the SATAN package, an introduction to Linux installation specifics and support materials. This tutorial will NOT be for the security experts, but an introduction for those just beginning their journey into the vastly intricate territory of network security.

Stan Reichardt 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 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 CRONicle newsletter are secondary to his fascination with books and Linux. He loves his wife and son. He tolerates their dog.

TEC (Information Technology Expositions and Conferences) Expo 1999:

Do you want to come out and play for awhile?

For the past seven (?) years SLUUG has had a presence at the annual St. Louis ITEC Expo. (Formerly the Cervantes Computer & Office Systems Show) Free tickets should be available at our 12 May SLUUG general meeting. This year's ITEC Expo will be at the America's Center downtown on Wed & Thurs 19 and 20 May.

Many SLUUG members were introduced to our group by this event.

We need volunteers to provide a 1/2 day of their time. If we get enuff volunteers maybe we could make shifts as short as a couple hours. This event is a lot of hard work, a lot of fun, and a lot of planning. Time in the booth is busy, exciting, hectic and satisfying. Give yourself a chance to introduce someone else to UNIX (all flavors), our projects, our Special Interest Groups (SIGs) and our group.

Getting volunteers is just the first step. Christine Wanta will direct our effort again this year. However, in order to participate this year, we need NOT less than 8 other volunteers lined up by 15 March. The event itself is entirely during the workday but we may need help to deliver tables, books, etc the nite before (i.e. Tue 18 May).

Along with these efforts Steering Committee volunteers are needed to step up planning and finding tutorials and presentations for the monthly general meetings that follow. That is what we must do to keep new and old members coming back month after month.

Volunteers should email Christine at for details. Refer to for general show info. If you pre-register indicate "SLUUG member" in remarks.

Election Results!

SLUUG holds officer advisory elections at every February meeting. There was also a 5 year Board of Governor's position up for election.

Nominations were opened to the floor and the voting was nearly instantaneous. The elections were held in communist-block fashion even though all nominees were present.

Gary Meyer, an incumbent member of the Board of Governors, and the only announced candidate for this position, was re-elected.

All announced officer candidates were elected without opposition:

President - Gary Meyer

Vice President - Ed Wehner

Secretary - Rich Seibel

Treasurer - Christine Wanta

Any SLUUG member in good standing that attends at least two meetings in the previous year is eligible to hold office. Attendance at the general meetings and all SIG meetings are counted. Anyone that would like more information about the administrative duties for the organization, please visit our web site at, or contact Chris Wanta at

"Home Directories on Michelob." by Benson Schliesser

As stated in the Message Of The Day (motd) on Michelob:

...the /home directories & files on "michelob" and "dark" are NOT the same. Changes to your WWW ~home pages in /home/public_html were affected!

(note: this effect occured over 3 weeks ago)

...on 26 February we will rename the "dark" /home to /oldhome and we will NFS mount the "michelob" /home onto "dark". You will then have until 12 March to copy any //dark:/oldhome files to your //michelob:/home

What does this mean to you?

Put simply..

Make sure that you have your MOST CURRENT version of all files in you home directory ON MICHELOB.

Compare files in your dark home dir to files in your michelob home dir. And be careful to catch changes in either since mid December.

The times of saves and restores were mid December, mid Jan, and early Feb.

After we make that michelob home directory the NFS mounted home dir on dark (as well as simultaneously on michelob) on 26 Feb....

IF YOU HAVE FILES THAT HAVE BEEN UPDATED by your web page (ex. home page stats) or other changes to the current dark home dirs, you should copy those changes to the new common home dir after Feb 26.

In detail..

There are two versions of the home directories, one on Michelob and another on Dark, each from different backups, and each covering different time periods. (This happened during the recovery attempts following a recent hard drive crash, and can be best explained as a freak accident involving a tar command and a time machine)

In order to bring a bit of order back to the SLUUG "production environment", the home directories are going to be shared, off of Michelob, to its sister production box (and web server) Dark. The home directories as they currently exist on Dark will become /oldhome in order to make way for the NFS mounted /home from Michelob.

Then, on the 12th of March, granting everybody enough time to retrieve any valuable files from the "old" home directories on Dark, /oldhome will be permanently removed.

To summarize..



Fri Feb 26 1999 ----------------------------

# mv /home /oldhome

# mount michelob:/home /home


Fri Mar 12 1999


# rm -rf /oldhome
