11/01/2002 - Mark Post reported two articles from The
Register. The first was about the European Commission awarding a contract to study
"the issues of migrating government computers in member states to a Linux/Open
Source environment." The second article was about a pilot program to replace
desktop systems for police departments throughout England and Wales with Linux-based
11/04/2002 - Barton Robinson of Velocity Software
announced the beta program for a new product named zMON. "zMON is the real
time component of ESAMON without the historical functions normally provided with
ESAMON." Velocity Software is positioning it as "a lower cost performance
monitor that is current and well supported."
11/04/2002 - Barton Robinson of Velocity Software
announced that the Velocity Software web site had been updated with his most
recent VM and Linux performance presentations. He also commented "In
addition, the newsletter articles are now available to all without restriction."
11/05/2002 - Neale Ferguson announced that he
had contributed the necessary code to the "mono" project (an Open
Source implementation of the .NET Development Framework) so that C# could be
used on Linux/390. He gave URLs for downloading the software and instructions
for creating executables. He also commented that he is "attempting to
build an RPM that will contain a ready-to-run version. The project is only
at the 0.16 level so there's still a lot of work to do."
11/07/2002 - Neale Ferguson contributed a link
to an eWeek article about Sistina Software and Mainline Information Systems
porting the Global File System (GFS) to Linux/390, specifically for SuSE's
SLES distribution. Sistina has taken GFS proprietary, but an Open Source
project, OpenGFS, has taken the last GPL version and is enhancing and
11/07/2002 - Adam Thornton announced that
he has "built Linux-2.4.19 with NSS support and the notimer patch,
and made it into a series of Debian kernel packages." Adam explains
how to build the software from source, if desired. He also commented
"Contrary to the IBM recommendation, I recommend you set your
virtual machine size as low as possible before building the NSS..."
His reasoning was "The smaller it is when you gen it, the more
flexibility you have in your memory size later on." He also had one
caution: "24MB is the smallest I've been able to make reliably boot
when using the qeth drivers."
11/08/2002 - Dave Rivers of Dignus
announced the new versions of their Systems/C, Systems/C++ and Systems/ASM
products. Dave also commented "What makes this pertinent to this
mailing list is the new 64-bit support, including z/Linux. All of
the Dignus tools now run on z/Linux, as well as generating code for
11/08/2002 - In a follow up note to his
original announcement, Neale Ferguson reported that Linux/390 RPMs for
the C# Open Source package "mono" are now available. They can
be found under the "Older Releases" header for version 0.16.
Neale also commented "I don't think you need the -devel RPMs if you
just want to play. You will need to do the following as root:"
11/11/2002 - Mark Post reported finding a
new IBM Redbook titled "Experiences with Oracle for Linux on zSeries."
The abstract page reads:
11/11/2002 - In response to someone who
was having problems "trying to get the alien-converted rpm's
running on a Debian/390 system," Matt Zimmerman recommended trying
the native Debian packages at debianplanet.org. As it turns out, that
site doesn't have binary packages for Debian/390, yet, so the other two
options available were "to build the latest snapshot-tarball from
the mono CVS-repository," or to "apply the Debian packaging
diff from the debianplanet.org packages to the latest mono release or
11/13/2002 - Matthias Hein recommended
taking a look at section 3.5.4 of the "SAP on DB2 UDB for OS/390
and z/OS: Implementing Application Servers on Linux for zSeries"
Redbook for someone who was having problems building zebra from source
on SuSE SLES7. He stated that "we describe a way to compile
standard zebra sources using the configuration file of an older source
RPM on SuSE sles7."
11/13/2002 - Mark Post wasn't sure if he
was the only person who had missed the announcement of the Red Hat 64-bit
Linux for zSeries being Generally Available. Just to make sure, he sent a
note to the mailing list about it. He quoted Florian La Roche of Red
Hat who said:
11/14/2002 - In a series of postings, Adam Thornton made available a number of screen shots of various things running on Linux/390 that wouldn't normally be thought of, let alone attempted:
11/15/2002 - In response to a question about
network and system tracing tools, John Summerfield mentioned dsniff, strace
(which is included on all the major distributions) and ltrace. The ltrace
program, which "tracks runtime library calls in dynamically-linked
programs," is included with SuSE and Debian. The dsniff suite is
included with Debian.
11/15/2002 - Mark Post contributed the link
to a CRN article that talked about SCO group being the first member of the
UnitedLinux group to formally roll out a UnitedLinux-based distribution.
11/16/2002 - Neale Ferguson reported an
IBM press release that announced IBM had been "awarded a contract
by Mobil Travel Guide to provide the company with large-scale computing
infrastructure on-demand over the Internet." The service is based on
Linux/390 virtual servers.
11/16/2002 - Mark Post requested that companies
that provide commercial support for Linux/390 to state that in the mailing list.
He was interested in adding that information to the web site.
11/18/2002 - Jim Rich asked if anyone was using
the new Linux "NFS over TCP/IP" code yet. No one responded that they
were, but he got several recommendations to look into OpenAFS instead. Mark Post
pointed out the OpenAFS patches that are available from the Sine Nomine web site,
but Adam Thornton said they were for a fairly old version of the code. A recent
version should be used from the OpenAFS web site unless there is some reason to
stay with an older version.
11/18/2002 - Jim Silbley posted a link to the
current list of LSB (Linux Standard Base) certifications, and to an article on
IBM's DeveloperWorks site on how to write LSB-compliant applications.
11/18/2002 - Michael Morgan responded to a report
of a problem with NFS putting out a "can't get a request slot"
message. He said he wasn't able to resolve the problem, but worked around
it by mounting NFS file systems with these parms:
11/20/2002 - Jim Sibley was the first to
report the SuSE press release about their SLES8 distribution. The
announcement said that all versions, including the one for Linux/390
would be available in December.
11/21/2002 - Mark Post forwarded on a security
alert regarding Samba. The alert was from Slackware, but pertained to all distributions.
The alert described a security exposure in "versions 2.2.2 through 2.2.6 of
Samba that could potentially allow an attacker to gain root access
on the target machine. The word "potentially" is used because there
is no known exploit of this bug, and the Samba Team has not been able to
craft one ourselves. However, the seriousness of the problem warrants
this immediate 2.2.7 release." Mark suggested that everyone "either upgrade
on your own, or be looking for a new package from your Linux distributor."
11/25/2002 - Richard Hirst reported a problem with
the CMS file system driver/utilities. According to Richard "for 4K blocks of
zeros, CMS does allocate any disk space - it just sets the corresponding indirect
pointer on disk to zero. Attached patch fixes userland cmsfs; havn't looked at
the kernel module."
11/25/2002 - David Boyes mentioned that he had some
anti-spam meaures implemented on his email server. A number of people pleaded with
him to post the details to the list, which he did. David had some strong warnings
about who should and should not try to modify their mail configuration file:
11/25/2002 - Jim Elliott recommended reading a new
book on Linux and Open Source. He said "The book is NOT technical, but is
oriented towards managers and give a great overview of the business benefits,
legal issues, costs/benefits, etc. It also covers "governance" and the
support structure in words management can understand." The book is "The
Business and Economics of Linux and Open Source" by Martin Fink of HP
11/25/2002 - Dave O'Neill and Jim Elliott
both provided the URL to the online version of eServer magazine. The current
issue has an article in it by Alan Altmark on "Understanding z/VM
Integrity and Security."

11/27/2002 - David Boyes helped out someone who was
in the unenviable position of trying to use telnet on a 3270 terminal. As a short
term fix, he recommended that the person get a copy of Arty Eckock's TNVT100
program which makes that situation a little more bearable. That, and other
"goodies" are discussed in the URL below.
11/28/2002 - David Boyes of Sine Nomine Associates
announced that beginning December 2nd, 2002, Sine Nomine Associates would
"begin providing a low-cost CD media creation service for Debian/390
which will deliver a complete Debian/390 Linux distribution and applications
package installable via CMS tools with no obligation to purchase a support
contract, and also a commercial service and support offering for Debian/390
at a price which is not sensitive to the number of engines or number of
installed copies." He also commented that "The intent of both
offerings is to provide a stable, well-supported Linux distribution for the
390 and zSeries that can begin as an experimental or development system
without incurring large startup costs, and grow seamlessly into an
environment that can support production environments as your skills and
confidence with Linux on System/390 and zSeries grows."
