11/02/2001 - David Boyes published this URL with the comment "This would be a really good IBM ad...." IBM is creating a series of short (132KB) Flash animations. The web page says that IBM is doing it for our enjoyment. They're not bad. The four there so far are entitled "Evolution," "Passion," "Penguinstein" and "Meditation."

11/05/2001 - Neale "All I really do is read Linux news web sites" Ferguson reported this story which says that Red Hat is going to be going GA with their Linux/390 distribution "in the next 30 days."

11/09/2001 - Vince Re of Computer Associates published a pointer to a web page that contains information about a lot of CA's Linux/390 products, including GA ones as well as Betas.

11/10/2001 - Axel Wirbser of IBM announced a number of new patches available for 2.4.7:

  • Recommended patches for kernel 2.4.7 and s390 tools with fixes provided along with:
  • Recommended 31-bit and 64-bit OCO-modules lcs, qdio, qeth with bug-fixes.
  • Experimental kernel 2.4.7 patch for "order 2 allocation relief" for 64-bit. This patch is very S/390 specific (breaking all other architectures) and should only be applied when building a 64-bit kernel. The patch is not compatible with the "on-demand timer" patch and requires special OCO-modules.
  • 64-bit experimental OCO-modules lcs, qdio, and qeth compiled with the "order 2 allocation relief" patch.
  • The 31-bit z90crypt OCO module which has been updated with bug fixes, but it remains experimental. (No 64-bit version of z90crypt available.)

11/10/2001 - Karl Huf reported that Tantia is porting their Harbor backup software to Linux/390. It has just entered beta testing at this time. He also stated that neither the port nor the beta test are mentioned anywhere on Tantia's web site as of yet.

11/10/2001 - Herve Allen of Turbolinux announced "We've just made available on our ftp site two new sets of iso images for Linux for zSeries and S/390. The first one is a beta update to our current GA that includes things like netmask settings for CTC during install (fixes Samba issues), Gigabit ethernet during install, IBM's JFS, etc.
The second image is an alpha version of our distro that includes kernel 2.4.7 and glibc 2.2.4. We recompiled all the installed packages with glibc 2.2.4 and have included most of our previous updates as well."
He also cautioned "For our 2.4.7 alpha you really have to read the errata.txt file that you will see in the FTP download folder. This is critical for correct network setup."

11/12/2001 - Lionel Dyck reported a number of different articles about Linux/390 that have been published in NaSPAs Technical Support Magazine and that are now available online. Some of them are by people active on the mailing list, such as Lionel himself, and Adam Thornton.

Linux on S/390 and zSeries: Getting Started

11/12/2001 - Jens Sandmann of SuSE posted a link to a SuSE announcement that the long-awaited update to their Linux/390 distribution would be available by the end of November. Based on a 2.4 kernel, the update will support S/390 as well as zSeries processors.

11/15/2001 - Mark Post reported that he and Bradley Snyder of IBM had been working on a problem where one of Bradley's customers had made a dynamic IODF update to add some new CHPIDs and DASD to a Linux/390 partition, and then were unable to get the new hardware to be recognized by Linux. An LPAR de-activation and re-activation was done, with no good results. Finally, a Power On Reset (POR) was done, and everything worked fine. Bradley had a problem record open with the IBM hardware support team about this.

11/16/2001 - Thanks to Lionel Dyck, we now have PDF versions of two presentations that are in Microsoft PowerPoint format. The two presentations are Rick Troth's "Samba - just a quick look," and Ross Patterson's "User Experiences with Linux for System/390."

Mark Post posted one of the links at the bottom of the article which is a PDF file of an IBM presentation on the deal and how it happened.

11/21/2001 - Florian La Roche of Red Hat announced that their version of Linux/390 is now classified as Release Candidate 2, and is now available in a non-"rawhide" version. ISO images (a total of four) are also available. Braver souls can continue to download their software from the rawhide directories.

11/21/2001 - In response to a question about web application servers, Geoffrey O'Callaghan posted a link to an Open Source application server named JBoss. Samy Rengasamy, the original questioner, in turn posted a link to the WebApp module for Apache.

11/28/2001 - Mark Post reported an article reviewing Red Hat's 7.2 platform and SuSE's 7.3 version:
"But the new distributions aren't all about saving money: The two companies are also offering plenty of appealing features for enterprises. Red Hat's newest release, Version 7.2, brings several updates to the core functionality of the product, including built-in journaling file system support, and improved virtual memory management. Likewise, SuSE 7.3 offers greatly enhanced usability and a smooth migration path for shops that haven't yet fully committed to Linux.

"The new products scored well in our tests; each earning a Deploy rating."

Lionel Dyck reported a slightly different version of the article by the same authors.

11/28/2001 - Neale Ferguson created a PDF document "that contains most of what's found in /usr/src/linux/Documentation/s390. I've just done some wordsmithing, formatting, and prettying up." It's a little large at 1.2MB, but it can be found here:

11/28/2001 - Neale Ferguson reported an article on IBM's DeveloperWorks regarding "the specifics of the PKCS #11 implementation to IBM cryptographic hardware (openCryptoki) that is available in open source form here on developerWorks."
