02/01/2002 - After much wailing and gnashing of teeth about the SuSE SLES7 version not being available for no-cost FTP download, Joachim Schroeder of SuSE posted this announcement from Dieter Heussner, Product Manager for SLES for S/390 and zSeries. (Emphasis on the different offerings was added to help clarify the various options.)
02/01/2002 - Neale Ferguson posted a pointer to another
article, this one about some of the Linux and Linux/390 customers IBM had at LinuxWorld
in New York giving testimonials about their experience with the platform.
02/01/2002 - Neale Ferguson posted a pointer to an
article about the large increase in requests for Linux-based software that Computer
Associates has experienced.
02/01/2002 - Colman Fink posted a pointer to an
article about Linux/390 from Enterprise Systems Journal (this one much better
written than the last).
02/01/2002 - John Bessette reported problems trying
to get the IBM Java JDK 1.3 to work with SuSE 7.2 (2.4 kernel). Dan Hines replied
that JDK 1.3 is only for 2.2 kernels at this time, and that IBM is working on getting
it ready for 2.4. John later reported that he downloaded Blackdown's JDK 1.2.2 and
it was working well with his 2.4 kernel. Florian LaRoche of Red Hat gave the tip that
"You can still copy older libraries on your system and modify the Java wrapper
scripts to use these older libs and have the rest of your system updated to the newest
Red Hat Linux 7.2 has all this prepared as far as I know, you just have to install
the 'compat*.rpm' libs."
02/01/2002 - In response to a question about getting
the Zebra routing software to utilize two default gateways, and fail over to the second
one if the first is not available, Malcolm Beattie posted this response:
ip route add default nexthop via 10.90.2.1 nexthop via 10.90.2.2The kernel will perform NUD (neighbour unreachable detection) and fail automatically over to the backup default route if the first one fails. The syntax of nexthop also allows "dev NAME" and "weight NUMBER" but I think "weight" may only be useful if you have the kernel patches to allow load balancing across multipath routes on a per-flow basis (using the "equalize" keyword). This information is in the ip-cref.ps document (RedHat installs it as /usr/share/doc/iproute-2.2.4/ip-cref.ps in RedHat 7.2 for example) which is why it seems to be less well-known than it deserves to be. Note that this form of multiple nexthops with nud is specific to the default route and can't be used for other routes (though you can fall back to using policy routing features together with userland daemons as you had originally planned)."
The ip command that Malcolm references is in the iproute or iproute2 RPM, depending on your distribution.
02/05/2002 - Aurora Emanuela Dell'Anno of Candle
Corporation announced the general availability of OMEGAMON XE for Linux/390.

02/05/2002 - Since the Debian port of GNU/Linux/390 is
pretty complete, a link to the binary downloads has been added to the "Binary
distributions" menu at the left of the main page. That link, and a link to the
Debian S/390 port page will be added to the http://linuxvm.org/Info/l390link.html

article about the US Defense Advanced Research Projects Agency announcing that it
will be funding a security audit of Open Source programs.
02/06/2002 - Mark Post reported an article wherein
Larry Ellison of Oracle talked about his view of the IT industry, and that he thinks
it is "inevitable" that "large servers" will die off. The
article made Mark wonder about the possible implications for Oracle's support of
its products on non-Intel platforms, such as Linux/390.
02/07/2002 - Mark Post announced that he had added
a "community members" page to the web site. A link to the page has been
added on the left side menu under "Community". Pictures and short
biographies of pictures of the people who contribute to Linux/390, either through
their work as developers, or by giving help in the mailing list will be added as
they become available.
02/08/2002 - In response to a question if anyone
had ported the rxsocket function for Regina to Linux/390, Arty Ecock replied "
Pierantonio Marchesini of CERN did a port, circa 1995 (!) to Regina. This URL
Pierantonio Marchesini C.E.R.N. ETH Zurich CH-1211 GENEVE 23 email: email@example.com Phone: +41.22.767.50.23 firstname.lastname@example.orgPierantonio made a few other nice additions to Regina. The source updates were in an AFS directory at CERN, but I never had a chance to request the address." Mark Post later replied that the source code appeared to be available but that the changes were most likely against a rather old version of Regina.
02/08/2002 - For the developers amongst us (and the
people who want to be) Neale Ferguson published this URL, which is a list of tips
and hints from IBM on porting programs to Linux/390.
02/11/2002 - Neale Ferguson reported that the IBM
Java JDK 1.3 was available for download now. His comments were "JDK 1.3.1
for 2.4 and 2.2 kernels. There is a disclaimer about running under 2.4 under
times of extreme load."
02/11/2002 - Philip J. Tully published some VM and TCP/IP maintenance that he said is necessary to get HiperSockets to work with Linux/390 guests:

tape support, Dennis Andrews of UTS Global replied that their tape driver "supports
3480, 3490 and 3590." It is available for download, but requires free registration
to access. He also commented "Note that we have moved our downloads from our ftp
to our web site."
02/15/2002 - Mark Post reported stumbling across an IBM

failing to start, Herve Allen of Turbolinux noted that he had created a document on
netmasks, Samba, and how to correct the problem manually after installing Linux/390.
The document is specific to Turbolinux, but should be easily transferable to other
distributions as well. He also noted:
02/20/2002 - Neale Ferguson posted a link to another
article on Boscov's conversion to Linux/390. This one talks about some of the financial
planning benefits, as well as some figures on servers replaced, electricity, etc., saved
and so on. This is done in the context of IBM winning Datamation's Product of the
Year 2001 award for server hardware. David Mastrobattista of Giga Information Group
provided some clarification of the numbers contained in the article:
02/21/2002 - In response to a question about upgrading
Python from 1.5 to 2.x, John Summerfield recommended against doing that because of a
number of compatability problems. The one possibility of upgrading gracefully that
he mentioned was the python-2.2-7.src.rpm package in Red Hat's rawhide directory.
That appears to have been upgraded to the version below.
02/22/2002 - David Boyes that Sine Nomine Associates
had "completed initial testing of a Linux for S/390 and Linux for z/Series port
of the Globus grid computing tools. I'll be putting together a binary package shortly
for the Globus team to distribute via their WWW site, and they will remain the
distribution point." He also stated that a version for z/OS Unix System Services
is in progress, but proceeding more slowly. He gave this brief description of Globus:
02/22/2002 - In response to yet another request for

COBOL compilers for Linux/390, and came across PERCobol from LegacyJ.com.
Apparently, this is the same organization that used to be at
According to Samy, the COBOL Code is compiled into Java byte codes and
LegacyJ provides a platform specific proprietary runtime. It wasn't clear
if there was a Linux/390 version available or not, but a visit to their
web site revealed this statement: "PERCobol Enterprise for Linux on
S/390 is available on IBM S/390" There was even a press release dated
April 27 of 2001 about the product.
02/27/2002 - Mark Post posted a link to an
InfoWorld article about Linux User Groups (LUGs) as a source of help for
people unfamiliar with Linux. The article also had a link to a web site
that can assist in finding a LUG near you.

a security exposure in the PHP scripting language. According to the report,
there is a severe security exposure in just about every version of PHP (3.0
all the way up through 4.1). The details are described at
According to php.net, there is a replacement version available, 4.1.2.
They use the phrase "strongly encouraged" to describe the
recommendation to upgrade.
