7:30 PM Presentation DNS/BIND release 8.2 - why you need to upgrade by Dave Dickerson


What is an IP Address and Internet Addressing by Stan Reichardt

This tutorial will be based on two short tutorials developed by the InterNic 15 minute series. This series of basic tutorial slides can no longer be found on the Internet.

This material covers the most basic concepts necessary to further understand Domain Name Services. This is introductory material. It is not for the experts, gurus, or sharpshooters out there.

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 Unix and 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.

His last SLUUG tutorial was on "Running the SATAN Security Tool under Linux" at the March 1999 general meeting. It was long.

His first SLUUG presentation was on "Learning VI Editing Commands" at the July 1999 general meeting. It was even longer.


DNS/BIND release 8.2 - why you need to upgrade by Dave Dickerson

The staid, time-proven Domain Name System is fundamentally changing. DNS on UNIX is generally so reliable that many people configure it and forget about it. It may be difficult to believe, but it is time for UNIX administrators to pay attention to their DNS servers.

BIND, the Berkeley Internet Domain server, is far-and-away the most common implementation of DNS in existence. A major upgrade to BIND from release 4.x to release 8.2 needs to happen in most organizations during the next few quarters.

Several factors drive the need to upgrade including security, availability, and Microsoft's Active Directory's reliance on Dynamic DNS. Windows 2000 and Active Directory require DDNS to function. If your DNS infrastructure is on release 4.x, it will not provide the DDNS that Windows 2000 requires.

This presentation will describe how DNS works and how BIND release 8 is configured. We'll discuss some common tools for managing and trouble shooting DNS, some of the new features in the current release of BIND, and some of the likely future features for DNS.

Dave Dickerson joined the St Louis UNIX user group at it's inception. With nearly twenty years of UNIX experience, Dave's areas of expertise include Systems Administration, Networking, Security, and Systems Management. Dave's recent projects include: network capacity planning and reporting systems, implementation of a network operations center, creation of highly available UNIX clusters over both LANs and MANs, and extensive network and systems management consulting services. Dave is also well-versed in Internet-related services including DNS, sendmail, firewalls, and Apache.

Dave's last SLUUG presentation was on "NFS, NIS and Core UNIX Services" at the May 1999 general meeting. His December 1997 presentation for SLUUG was a singularly outstanding one on using free security tools.

For more info contact Dave Dickerson by sending .

[ Editor's Notes:
WOW!! Even if you don't know what it is, if you can spell DNS, then you need to attend this meeting!

Dave is Mister Security, the kind of guy that is paid for what he knows, not what he does. But, he does leading edge stuff anyway, and does it right.

Just being in the same room with Dave will make you smarter. ]

    SLUUG BBS Systems Update by Gary Meyer

    Our cluster of machines known as "the BBS" are still living at CTItek for a couple more weeks. A big thanks to Tony Zafiropolous for helping us out and taking us in.

    We had some downtime on Tuesday nite 28 Sept until about 2:30 Wednesday. We moved into the new CTItek offices but there were troubles getting connected on the ISDN circuit. No doubt the storm that nite increased the wait time for getting assistance from SouthWestern Bell.

    We will be moving the systems to a more permanent home this month.

    See previous month's newsletter article at for very detailed background and some good references to alternative resources.

    Please contact Gary Meyer by sending if you need more specific information on the hardware or other aspects of these SLUUG computer systems. - Alternate SLUUG home page, if our server goes down.

    Attendance Survey Results

    We may continue to forego more survey questions over the next month or so.

    Tutorial Suggestions Wanted

    Apparently LINUX SIG attendees want more tutorial material.

    A number of attendees at the September Linux SIG meeting expressed a desire for an increase in introductory and tutorial level material.

    A number of the attendees noted they were reformed Micro$oft victims and were interested in material that was generic UNIX as opposed to specifically LINUX, or advanced subjects.

    It was pointed out that it is unlikey that time for a seperate tutorial will be worked into the Thursday nite SIG meetings. But we will try to keep the Wed nite general meetings format of having an introductory level tutorial at 6:30 each month.

    People with requests or suggestions for any tutorials should please send them by for consideration at the Steering Committee meetings.

    There was a report on NPR Tues evening (14 Sept) that the U.S. Army revealed that it had changed the OS on its web site some months ago.

    The web site had been frequently broken into by hackers who turned it into graffitti.

    The Army decided to give up on Windows NT saying that it was economically impossible to secure that operating system.

    The Army replaced it months ago with MacOS! They found that MacOS came "out-of-the-box" with only 1 open door.

    Microsoft responded with the comment that WinNT is running close to 36% of all web servers and MacOS less than 1%. MS believed that the hackers will learn to attack MacOS as it becomes more prevalent.

    Neither side mentioned the elephant in the corner of the room that is the OS for the over 63% of the web-sites.
