Re: Utilizing Linked minidisk in a reiser LVM environment

[Post, Mark K]

Two things to check.  Make sure /etc/fstab specifies that the file system is
to be mounted readonly.  Also, in your parmfile where you specify DASD
device numbers, make sure that you specify 107(ro).  So, for example, you
would have:
100-105,107(ro),191

Subject: Utilizing Linked minidisk in a reiser LVM environment


We recently loaded UDB V8.1. We created an LVM using reiserfs as a single

We are hoping to use this as a single UDB reference in all our LINZ servers.
On a second server I defined a link to the first servers 107 disk RR.

Okay, I'm still having issues with the Guest LAN using Virtual
Hipersockets.
Below is what I have coded for the Linux Master.  I can get to the machine
using the VCTC, but I can not get to the machine via Virtual Hipersockets.
I can get to the 10.22.25 subnet from the VCTC connection, but that won't
do.  I need to find a way to get the working without the VCTC.  It seems
that my primary problem is on the Linux side, but I can not figure out why
this will not work.  Do I need to have a physical Hipersocket or physical
connection via OSA-E to point to as the gateway for the Linux machines?
Sorry for constantly returning, but I think I'm getting close with the help
I've received thus far.

There's also Knoppix from .de.

And a couple of firewall setups that run from CD.

I've got my own installer. I boot a floppy containing an Etherboot
bootrom, and that loads a kernel and initrd (standard Debian kernel in
fact) off a tftp server and runs that.

The linuxrc in it establishes a network connection (modprobes my NIC
drivers until one takes) and mounts a filesystem over nfs.

While this system is my installer, it could actually be any Linux setup
at all. a firewall on a ro filesystem, a xterminal, a full desktop
setup.

If you're asking how to tell which physical volumes make up a logical
volume, lvdisplay -v  will show you where each logical extent is
stored.

If you're asking how to tell which physical volumes make up a volume group,
vgdisplay -v  will tell you that.

Some time go, Kaspersky released a desktop AV package for Linux. It was
offered as a free download by (I think) zdnet. The announcement was
greeted with guffaws and exclamations of "Who needs such a thin?"

Well, ever eager to learn, I asked Kaspersky. The first reply was
toovague, so I asked again, pressing the point I wanted to know
specifically what viruses were around.

The list came back with such dreaded names as lion, Ramon and three
others so notable I don't recall them.

Those I recognised are actually worms, and greybeards at that. None
could infect any reasonably up2date system.

In my view, the risk of an actual virus getting about infecting Linux
machines is fairly slight. Consider;
Most Windows viruses spread by using Lookout Express and other office
procut APIs. A great way of reducing your risk of infection on Windows
is to use some other email client and office suite.

MS Office products are not available for Linux.

Now, it might be that if everone on Windows used, say, Eudora and
SmartSuite then those products would be found to have similar problems.

On Linux, there is no predominant email client as there is on Windows.
Some use Ximian Evolution, others use Kmail or Mozilla or Balsa. At the
moment I'm typing away in Pine, many prefer Mutt.

I tried running executale content from Kmail (which I use a lot), and
failed. If you manage to do it with any Linux email client, file a bug
report and use something else.

Linux does not run Windows programs, especially if you don't install
Wine or Crossover. Therefore, it's not troubled by Windows Wogs.

Even if you did get a Linux virus, the damage it would do is limited to
the account of the user that received it. Others would be unaffected.

Now, trojan horses are another matter. If I can persuade you to run
"this nifty little program" then it can do damage to you (even if it
does what I said it does), and if I can persuade you to run it as root,
then it can do considerable damage.

I don't think AV software will help much with that.

And there are worms, programs that search you out like that one that
took Korea off the net a week or so ago. They can be serious. While one
that infiltrates your webserver won't do anything your webserver can't,
that can still be serious, especially if the cracker knows enough about
your system to get into your corporate data. Think espionage.

I don't think AV software helps there either.

Having said that, there is room for AV software on Linux. If you're
providing file-sharing and email services to Windows clients, you will
want to run AV software on Linux to protect those windows boxes.

Knoppix Linux at http://www.knoppix.org

It's an excellent way to show someone (yourself) what Linux would look like running on 
their own machine (but without touching their hard drive). I always carry a copy in my 
knapsack for those moments when my eloquence is not enough to convince :-)

Seriously, they've done some excellent work on device recognition. I had a hard time 
to get sound working on my thinkpad but knoppix worked right off... Other cool 
techniques, like compressed filesystem, etc. make it pretty neat to work with... 
Downside is that it's obiously a little slow to load.

Re: Root almost filled on 3390-3

[James Tison]

Werner,

It's usually not the "root" (/) filesystem itself. It's usually one of the
directories underneath it that you left on the same device, for example,
/tmp, or perhaps even /var or /usr, depending on how your system is used.
If it were me, I'd locate the offending directory and just move it off of
that device. Sounds like you have a candidate for another directory to put
in your LVM pool if its growth has gone undetected all this time, or maybe
it deserves its own device. Doing the move itself is pretty simple.

Good luck,

There are very few linux worms. And this is not because it is difficult to
write one (anybody for a shell virus?) but because:

* linux (like most server-originated systems) systems were designed in
  advance to be multi-user systems (where a user cannot harm the system).
  Anything that allows a user to gain more priviliges is considered a hole
  that should be fixed immeditely (even if it is "theoretical").

* The syste is quite modular. Applying changes is generally quite easy.
  Systems tend to be kept up-to-date with security patches. (you're not
  afraid that they're going to break too much).

As for a cross-platform "virus": it is theoretically possible, but not
very likely.

THe problem is a "worm", that is able to automatically infect other
systems. Normally it wouldn't be able to "infect" a system, unless that
system is very badly broken.

Many of those holes require some platform-spesific code. It is possible to
adapt the worm for multiple kinds of hosts and this has been done in the
past. But most arent. At least not when you have so many poorly-maintained
intel boxes that largely outnumber the other archtectures. (which are
typically servers that are better maintained).

(That doesn't mean you shoudn't secure your system, of course!)

Anyway, there is no reason to run a virus scanner on linux, other than to
scan data (files/mails/etc.) used by windows/mac clients (even if some
vendors, like Symantec, would like you to believe otherwise).

No, I can't say I have.  But, if you want to mollify them, tell them about
RAV Antivirus, which runs on Linux/390.  If you turn your Linux/390 system

Maybe they think that if they use open source software as part of their

AFAIK, it doesn't matter unless you distribute your software with the OSS

They're usually called Live-CDs.  I know Gentoo did a nice once recently
that was basically the infrastructure support for Unreal Tournament
2003.  Pretty cool.  SuSE used to hand out LiveCDs at tradeshows and
stuff, but I dunno if they still do.

IBM's Newest Enterprise Storage Server Drives Open Standards

[Ferguson, Neale]

See: "http://linuxtoday.com/news_story.php3?ltsn=2003-02-05-011-26-NW-HE-SV";

"IBM today announced the delivery of the first industry standard
interface
for the IBM Enterprise Storage Server (codenamed 'Shark') based on
'Bluefin,' a
specification designed to help customers more easily manage storage systems
in a
multi vendor storage network.

"IBM is also expanding storage support for mainframe customers running
the
open Linux platform, one of the fastest growing customer segments...

"As the use of Linux across customer's e-business infrastructure
expands,
storage needs will grow, especially in mainframe environments. IBM's ESS now

supports IBM eServer zSeries customers running the Linux operating system

Re: OT (almost) - boot Linux from CDROM on Intel?

[Rod Furey]

CD based

SuSE Live Eval - as mentioned in Michael's post
DemoLinux - www.demolinux.org
Knoppix - www.knoppix.org

There are various projects around the net that are working on this sort of
thing as well. There are others that you can boot off floppies but these
tend to be fairly small systems that are designed for rescue acts.

A word of experience: I use a copy of the SuSE Eval CD when I'm fixing
other people's PC problems. I got it off the front of Linux Format, one of
the UK mags (which I read, I'm in no other way associated with them). It's
a 7.1 release and unfortunately it doesn't pick up everything on all
hardware. I've got a friend who's got a PackardBell "laptop on it's side"
model and the mouse isn't picked up. Curiously enough, the Mandrake 7
release will find it if it's installed. Sometimes it won't pick up modems
or sound cards either.

Before the SuSE people jump on me I'd like to point out:

1 - I offer this as a reminder that some kit just isn't recognised

2 - I know it's old

3 - I'm on a dialup line so I'm not about to spend 24 hours downloading
any newer version

4 - I use SuSE as my primary Linux install on 2 boxes at home (the other
boxes being iMacs which are running OS 9 and/or OS X) as it was the
only distro at the time that would correctly configure my X
installation (and a good job it did of it too)

Maciej, did you select "Configure Device Driver Modules" when you've

Maybe they think that if they use open source software as part of their

AFAIK, it doesn't matter unless you distribute your software with the OSS

I haven't gone through a Debian/390 install with OCO modules, but I would
think that at some point you would need to copy the OCO module from the
ramdisk to your /lib/modules tree so that the installed system could access
it after the IPL.  You should just be able to re-IPL the starter files, do
the copy, chroot to the root file system, re-run depmod, exit, and re-IPL
from DASD.

For my unsuccesful attempts I used a ".ins" file created by myself and I

Is it so because I didn't load the oco.bin file ? I tried to find it on

I installed the base system over the network (through FTP) without any

Re: Root almost filled on 3390-3

Wolfe,
thanks for your reply. The du command was a great help in finding the culprit.
There were two files in /tmp from the installation of a DB2 fixpack which used
up a lot of space. Now we are at 40% and 870MB.
However, I'd still like to know which directories can be moved to LVM managed
space (only those which will not be accessed until LVM initialization). Is this
usual to have parts of root fs in LVM space? In my opinion /var, /usr and /tmp
would be good candidates, wouldn't they?
Sorry for the dumb questions, but I'm just starting with Linux.

The Systems Administration Facility (SAF) is the z/VM "compatibility mode"
for customers who were using the Virtual Image Facility (VIF) product.  It
is *not* a replacement for DirMaint.

If you were not previously using VIF, then I do NOT recommend that you use
SAF.  While it makes the system easier to administer, it has a lot of
limitations that will frustrate you.

Use DirMaint.

Future of LVM, was RE: Root almost filled on 3390-3

Gordon,

Most likely, they were referring to EVMS, IBM's Enterprise Volume Management
System.  And actually, they were 180 degrees off.  LVM2 has been decided
upon as the direction for the (immediate) future.  The IBM team that
develops EVMS has decided to drop their kernel extensions, and concentrate
on the administration tool aspect of the package instead (in the long run).

Werner,

I'm glad I was able to help you find your storage problem.  I remember when
sonmeone showed me the "du" command about a year and a half ago how useful
it was to me.

As far as LVM is concerned, there are others on this list who are more
qualified to speak about LVM than I am.  I'm sure this question has been
answered in this list before.  You might check the list archives at
http://www.marist.edu/htbin/wlvindex?linux-vm and do a search (at the bottom
of the page) on LVM.  Be patient.  The search can take a while.

Having said that, I do seem to recall that someone posted the fact that even
the boot disk can be on a logical volume.  Probably any mount point can be
on a logical volume.

Here at Boeing, we use LVM volumes mostly for user data, /home for example,
or for Oracle databases, so that we can use more than one physical volume
for a mount point.  We also keep the Oracle code in logical volumes so we
can have more than one mount point on a minidisk.  For our general purpose
(non-Oracle, non-WebSphere) linux systems, we create the following
minidisks:

292 mounted as / (boot disk)
293 V-disk for swap
294 mounted shared read-only as /usr
295 mounted as /home

For boot purposes, Linux needs to have (at least) access to /boot, /bin,
/sbin and /etc on the boot disk until it is up far enough to mount other
filesystems. It may also need /var or /tmp.  It definitely does not need
/usr, /opt or /home unless you've done something really radical to change
your system.

One more thing.  I wouldn't get too enamored of LVM just yet.  I was in a
meeting yesterday and one of the Unix gurus we work with on Linux/390 (and
who is usually pretty knowlegeable about these things) mentioned that LVM is
going to be sunsetted.  It is rumored that Sistina will not be enhancing it
beyond the 2.4 kernel, only providing basic maintenance.  This same person
said that Linus won't be putting LVM into 2.6 when it comes out.  LVM will
apparently be replaced by something similar but more capable from IBM, and
that this new filesystem is already in the 2.4.17 kernel.  There was an IBM
rep there at the meeting and he seemed to know about this change as well.
We've put all our expansion of LVM on hold until we find out if this rumor
is true and (if so) what the replacement is and how you work with it.

Perhaps others on the list can expand on this rumor and tell me if I'm just
blowing smoke and spreading FUD.

They say there are three signs of stress in your life.  You eat too much
junk food, you drive too fast and you veg out in front of the TV.  Who are
they kidding?  That sounds like a perfect day to me!

Re: Suse 7 kernet 2.4 Packages

[Post, Mark K]

Ken,

1. That's the way you make sure that what ever DASD you add will be
recognized at the next IPL.  To make them available now, do an:
echo -n "add device range=addr1[-addr2] " >> /proc/dasd/devices
If you're only adding one volume, only specify one address.  If you're
adding multiple volumes, that do _not_ have contiguous device numbers, issue
one command for each device number.

After that has been done, you should able to run dasdfmt, fdasd, and mke2fs
on them.

2. Source RPMs (.src.rpm or .spm) are usually installed in to
/usr/src/packages/SOURCES.  If you install something named
"kernel-source-vv.rr.mm-b.rpm", then that will go somewhere else.  You would
be able to query that with "rpm -qf kernel-source" and it would most likely
have been /usr/src/linux-2.4.7-something.  It's entirely likely that the
files were already on your system, and you simply overwrote them, resulting
in no additional space being needed.

Hi,

I have 2 questions:

1.) I added new DASD today to our Suse 7 system, kernel 2.4.  I edited
/etc/zipl.conf and added the new DASD, and then I issued a zipl.  Is this
the correct way to add DASD?

2.) One of our testers wants the kernel source, so I perfomed the
following steps:
-> Yast
-> Package management
-> Load Configuration
-> Change or create configuration
-> selected zq Source packages
-> selected kernel-source_spm
When I selected the item, the amount of free space went from 95.7mb to
71.8m
-> Start installation
It then downloaded the package and showed Installation complete

When I looked at the amount of free space on the one disk, it had returned
to 95.7.  It seems that the source has not been installed.  I have 2
disks, one with 95.7mb free, and the second with 2.11gb.  I also tried a
smaller source that even when expanded would have fit on the first drive,
but I get the sane result.

Does anyone know what step I am missing?  Also, once I finally do get the
source, what directory will it be in?

Thanks,

> Hi all, somebody knows whats the diferences between the System

SAF was intended to be a "black box" VM management solution for Linux
guests that involved no knowledge of CMS or CMS functions, similar to
the approach taken by the mercifully short-lived VIF product. It is very
limited in what it can do, and does not allow you the full power of the
VM environment. DIRMAINT is a much more full -function user directory
manager, but assumes you are willing to learn a little bit about the CMS
environment and how it functions. DIRMAINT is much more general-purpose,
and allows you to do all the good things that VM can do.

I believe SAF can use DIRMAINT if it is available, but SAF is not a
replacement for DIRMAINT.

The general opinion I've heard is that SAF is too limiting to be of much
use in a production environment.  It does not understand many of the
recent enhancements to the Linux environment, and is not generally
useful for environments other than managing Linux guests. The first time
you need an advanced function, SAF must be turned off and further
management performed with the standard VM tools. Once SAF is disabled,
there is no way to turn it back on.

Short summary: invest the time in learning the native tools. SAF is not
a replacement for DIRMAINT.

Re: Yet Another Systems Programmer Trying to Install Linux390

[Dyer, Kenny]

Mark,
Thank you for your reply.  I was afraid that would be the answer.
I attended an IBM zOS Expo presentation back in 2001 called
'Linux in an LPAR: Here's How It's Done' and the handout shows
an option '7) CLAW (Cisco Mainframe Channel Connection)'.
My menu shows options 0-6, skips 7, then 8-9. I guess '7' was
an experimental option.

Thanks again.
Kenny

Kenny,

Having been through this before myself with an LPAR install, the path of
least resistance here would be to use the Ethernet adapter to get the system
installed and running, and then compile the CLAW driver and start using it.
That will involve the least amount of hair loss during the process.

I've downloaded SLES7 beta to try in an LPAR.  The only configured tcpip
connection to our
MP3000 H50 is thru a Cisco router running CLAW.  The network connection menu
from
the IPL tape does not include CLAW as a choice.  What are my options from
here?  I'm
considering configuring the MP3000 ethernet adapter just to get by this, but
would rather
use the Cisco router.

Re: Root almost filled on 3390-3

[Wolfe, Gordon W]

Werner,

I'm glad I was able to help you find your storage problem.  I remember when sonmeone 
showed me the "du" command about a year and a half ago how useful it was to me.

As far as LVM is concerned, there are others on this list who are more qualified to 
speak about LVM than I am.  I'm sure this question has been answered in this list 
before.  You might check the list archives at 
http://www.marist.edu/htbin/wlvindex?linux-vm and do a search (at the bottom of the 
page) on LVM.  Be patient.  The search can take a while.

Having said that, I do seem to recall that someone posted the fact that even the boot 
disk can be on a logical volume.  Probably any mount point can be on a logical volume.

Here at Boeing, we use LVM volumes mostly for user data, /home for example, or for 
Oracle databases, so that we can use more than one physical volume for a mount point.  
We also keep the Oracle code in logical volumes so we can have more than one mount 
point on a minidisk.  For our general purpose (non-Oracle, non-WebSphere) linux 
systems, we create the following minidisks:

292 mounted as / (boot disk)
293 V-disk for swap
294 mounted shared read-only as /usr
295 mounted as /home

For boot purposes, Linux needs to have (at least) access to /boot, /bin, /sbin and 
/etc on the boot disk until it is up far enough to mount other filesystems. It may 
also need /var or /tmp.  It definitely does not need /usr, /opt or /home unless you've 
done something really radical to change your system.

One more thing.  I wouldn't get too enamored of LVM just yet.  I was in a meeting 
yesterday and one of the Unix gurus we work with on Linux/390 (and who is usually 
pretty knowlegeable about these things) mentioned that LVM is going to be sunsetted.  
It is rumored that Sistina will not be enhancing it beyond the 2.4 kernel, only 
providing basic maintenance.  This same person said that Linus won't be putting LVM 
into 2.6 when it comes out.  LVM will apparently be replaced by something similar but 
more capable from IBM, and that this new filesystem is already in the 2.4.17 kernel.  
There was an IBM rep there at the meeting and he seemed to know about this change as 
well.   We've put all our expansion of LVM on hold until we find out if this rumor is 
true and (if so) what the replacement is and how you work with it.

Perhaps others on the list can expand on this rumor and tell me if I'm just blowing 
smoke and spreading FUD.

They say there are three signs of stress in your life.  You eat too much junk food, 
you drive too fast and you veg out in front of the TV.  Who are they kidding?  That 
sounds like a perfect day to me!

OT (almost) - boot Linux from CDROM on Intel?

Subject: Sytek Services has been acquired by DSG


[Cross-posted to the VM and VSE listservs]

I have some exciting news to share with all of you: Sytek Services has been
acquired by a Tier-1 IBM Business Partner named DSG (formerly Denver
Solutions Group), effective 01Jan03.

Sytek Services will continue to operate as a separate corporation, wholly
owned by DSG, under my direction and with the same philososphy and attention
to Linux on the Mainframe (and VM and VSE as well) as an important growth
area. Everyone on board at Sytek was offered an equivalent position in the
new organization.

DSG is IBM's largest reseller of mainframe hardware and software nationwide
(Mainline might dispute this, so I guess it would be safer to say that DSG
is one of the top two). In any case, the acquisition of Sytek by DSG will
give Sytek more resources to help promote and sell infrastructure and
application services to zSeries sites nationwide.

Here is the official press release:

---

DSG Purchases Sytek Services, Reaffirming DSG's Commitment to Linux

Englewood, Colorado - January 10, 2003:  DSG has purchased Sytek Services of
Bellingham, Washington.  The integration of the two companies further
expands DSG's service and support offerings for Linux, z/VM, z/OS, and
VSE/ESA.

`A key driver to this acquisition is to deliver the highest quality service
and support for Linux at a price point that will make sense to our
customers' declares Rick Bailer, Vice President of Sales at DSG. `We believe
that we can offer customers a more responsive and comprehensive plan without
premium pricing' agrees Bob Kusche, former President of Sytek and new
director of the Sytek Services division of DSG.  `By doing so we will be
able to open doors that previously were closed due to cost'.  The net
benefit is that DSG will be better able to help customers move from Linux
'proof of concepts' and pilots to full production Linux environments and
have confidence that they will have cost- effective up front, on-going and
24x7 perform level support.

Sytek Services is no stranger to the IBM zSeries and Linux world. Originally
founded as VM Assist, Inc. in 1986, the company has specialized in providing
24x7 services and support not only for the VM operating system, but all
other IBM mainframe operating systems. When Linux was introduced to zSeries
in May 2000, Sytek became a market leader in working with customers to
identify and implement Linux solutions. Combining their VM skills with Linux
has proven to be a powerful combination for Sytek as more and more companies
turn to the mainframe to run Linux applications.

`This is a significant step forward for both DSG and Sytek Services.'
declares Tom Engleby, President of DSG. `We recognize the momentum that
Linux has gained in the marketplace as DSG has over 50 customer that we are
actively partnering with to implement Linux solutions. With this acquisition
we have taken the steps to insure we fully service our customers as they
embrace Linux. What we have done not only benefits DSG, it furthers the
cause of Linux by demonstrating the reality of its total cost of ownership
story. Linux has reached the point that the technology is no longer in
question. Rather, the business case and financial case needs to be proven.
DSG is prepared to do just that.'

About DSG:
DSG, formerly Denver Solutions Group, was incorporated in 1991 as an IBM
Business Partner. DSG originally focused on S/390 high end and storage
solutions; but has expanded to remarket IBM's full eSever product line and
associated peripherals. Since 1991, DSG has experienced a 50% year-to-year
revenue growth.  Over 100 professionals are now in place actively providing
coverage to every state in the nation.  DSG, a Premier IBM Business Partner,
prides itself in the depth and experience in all IBM hardware and remains
committed to exclusively marketing IBM eServer based solutions.

About Sytek Services:
Sytek Services, Inc. first opened its doors as VM Assist, Inc. in 1986,
initially focused on providing VM and VSE operating system services. The
company was renamed to Sytek Services in early 2000 when Linux for zSeries
was introduced, and has since focused all efforts on management consulting,
integration, implementation, and 24x7 support of Linux for zSeries
infrastructures. Sytek is currently expanding its Linux offering to all IBM
eServer platforms, and has personnel covering customer sites nationwide.

Suse 7 kernet 2.4 Packages

[Ken Vance]

Hi,

I have 2 questions:

1.) I added new DASD today to our Suse 7 system, kernel 2.4.  I edited
/etc/zipl.conf and added the new DASD, and then I issued a zipl.  Is this
the correct way to add DASD?

2.) One of our testers wants the kernel source, so I perfomed the
following steps:
-> Yast
-> Package management
-> Load Configuration
-> Change or create configuration
-> selected zq Source packages
-> selected kernel-source_spm
When I selected the item, the amount of free space went from 95.7mb to
71.8m
-> Start installation
It then downloaded the package and showed Installation complete

When I looked at the amount of free space on the one disk, it had returned
to 95.7.  It seems that the source has not been installed.  I have 2
disks, one with 95.7mb free, and the second with 2.11gb.  I also tried a
smaller source that even when expanded would have fit on the first drive,
but I get the sane result.

Does anyone know what step I am missing?  Also, once I finally do get the
source, what directory will it be in?

Thanks,

Ken Vance

An Intel Slackware question about the 2.4.x kernels

[Gregg C Levine]

Hello from Gregg C Levine
Most of you know, by now, that my primary Linux box, is an Intel one,
who runs Slackware Linux, in this case 8.0. It also is an UMSDOS
machine. That is it sits on the regular FAT32 partition, who uses the
2.2.19 kernel, because of the assertion by the folks at Slackware that
the UMSDOS handling is broken in the 2.4.x kernels. They have made
that one, based on the 2.4.5 kernel. In that it would break the file
system behavior. 

Would anyone familiar with the kernel creation process be able
confirm, or even deny that it has been repaired by the later 2.4.x
kernels? In this case it would be the 2.4.19, or 2.4.20 kernel.

I phrased my subject that way, so that people would have some idea
regarding the distribution I use.

Okay, I'm still having issues with the Guest LAN using Virtual
Hipersockets.
Below is what I have coded for the Linux Master.  I can get to the machine
using the VCTC, but I can not get to the machine via Virtual Hipersockets.
I can get to the 10.22.25 subnet from the VCTC connection, but that won't
do.  I need to find a way to get the working without the VCTC.  It seems
that my primary problem is on the Linux side, but I can not figure out why
this will not work.  Do I need to have a physical Hipersocket or physical
connection via OSA-E to point to as the gateway for the Linux machines?
Sorry for constantly returning, but I think I'm getting close with the help
I've received thus far.

That is true in concept, although fuzzy in the details. In 1973, S/370
virtual  had just been delivered, there was DOS/VS (born  of DOS), VS1
(first born of MFT), VS2 R1 (or SVS - first born of MVT). MVS came a
few years later. [No one talks about FS any more...]

In the late 1970s, IBM made a public commitment to resolve any
problems related to security/denial of service/etc ... in MVS. Now MVS
begat OS/390, which begat z/OS etc etc. It was the commitment to cure
security holes which made the difference.

Now it is: if you don't buy Linux, you just as good as fired.

Which is pretty well how my storage opinion piece for Computer Weekly starts:

Fashion often seems to rule the IT world - sometimes beneficially.  It used to be said 
that
you couldn't get fired for buying IBM - so many people thought the same as you that you

No, I don't think so. Since you are using a OSA-2 card this one should
be lcs-based, not QDIO-based? Since lcs is open source you shouldn't need
the OCO-modules.

> I tried to find it on the net but it was nowhere to be found.

Debian doesn't distribute the OCO-ramdisk due to legal concerns. You can
find a script for building the OCO-ramdisk on

http://people.debian.org/~sgybas/deb390/scripts/

But anyway, you shouldn't need it.

Have a look at the end of /etc/modules.conf on your installed system. You
should see something like

alias tr0lcs
#alias eth0   lcs
alias eth0   qeth
alias ctc0   ctc
alias escon0 ctc
alias iucv0  netiucv

Try changing this to

alias tr0lcs
alias eth0   lcs
#alias eth0   qeth
alias ctc0   ctc
alias escon0 ctc
alias iucv0  netiucv

(removing the # from the second line and putting it in front of the
third line). Now the lcs-driver will be used for your ethernet card
instead of the OCO qeth-driver (which probably is not installed on
your system). This hopefully will fix your problem.

Re: Power of Open Source - Microsoft Warns SEC of Open-Source Threat

[John Ford]

Maybe they think that if they use open source software as part of their
proprietary software that they would have to make their software open.
AFAIK, it doesn't matter unless you distribute your software with the OSS
stuff embedded (and thus no longer open). If I'm wrong... straighten me
out...

Okay, I'm still having issues with the Guest LAN using Virtual
Hipersockets.
Below is what I have coded for the Linux Master.  I can get to the machine
using the VCTC, but I can not get to the machine via Virtual Hipersockets.
I can get to the 10.22.25 subnet from the VCTC connection, but that won't
do.  I need to find a way to get the working without the VCTC.  It seems
that my primary problem is on the Linux side, but I can not figure out why
this will not work.  Do I need to have a physical Hipersocket or physical
connection via OSA-E to point to as the gateway for the Linux machines?
Sorry for constantly returning, but I think I'm getting close with the help
I've received thus far.

Re: Yet Another Systems Programmer Trying to Install Linux390

[Post, Mark K]

Kenny,

Having been through this before myself with an LPAR install, the path of
least resistance here would be to use the Ethernet adapter to get the system
installed and running, and then compile the CLAW driver and start using it.
That will involve the least amount of hair loss during the process.

CIO Today Article: The State of Samba

[Post, Mark K]

This was sent to me by a co-worker.  It's a fairly generic article about
Samba, until it gets to the end, when they quote Jeremy Allison about some
of the things that are going to be included in Samba 3.x:

The most exciting new feature in version 3.0, according to Allison, is Net
RPC Vampire.  This tool allows a Samba server to transfer the user database
from a Windows NT 4.0 domain server. "It sucks down the database ... and
then you've converted completely transparently. You've basically just
migrated to Samba..  It was a piece that was missing [in earlier versions];
we didn't understand how to work the account transfer."  Allison noted that
when 3.0 comes out, "it will be relatively smooth for people who want to
migrate from NT 4.0 to Samba instead of Windows 2000."

Very cool, considering this involves a bit of effort today.

eWeek's editorial board has decided that for IT buyers,
Linux is no longer a luxury. If you want to stay employed,
you'd better consider the OS for your future development
plans. And if you're serious about Linux, you need to
evaluate SuSE Version 8.1. Our reviewers found that it not
only makes a great desktop OS, it also plays very well with
others - including Windows. Check out how well it runs
Microsoft Office: you might just be able to trash Windows
but keep your apps!

I've long-sinced discarded my sysgen listings, but I think VS2 Rel 2.0
surfaced in Canberra briefly in 74 which is about when we took delivery
of our first 168.

 
> In the late 1970s, IBM made a public commitment to resolve any

The commitment was made with the introduction of MVS. I recall some
training we received from IBM folk at the time, and the statement was
made, "We will accept APARs for any security problems."

As a junior sysprog about then, one of my tasks had been to examine VS1
dumps. I quickly decided an 0C1 with PSWKEY=0 was IBM's problem, and a
few more inches (this is pre decimal) of paper went on the IBM stack..

In '94 I discovered a neat trick for killing off initiators. I don't
recall whether I was running COBOL or HLASM2 (the translators, not
application programs), but if the translator was told to use all the
region, the initiator died and dumped.

The sysprogs didn't seem interested in persuing it; I thought it
constituted a security-type problem. True, JES2 simply started another.

Re: Debian install problem

[Maciej Ksiezycki]

Adam, Mark Post and Jochen - thank you for your replies.

For my unsuccesful attempts I used a ".ins" file created by myself and I
didn't know that the filenames might not be too long.
When I used the original ".ins" file from the Debian CD and changed the
filenames according to it, the installation went smoothly until the
first IPL. After the IPL I get a message from modprobe:
"can't locate module eth0". I am using OSA-2.

Is it so because I didn't load the oco.bin file ? I tried to find it on
the net but it was nowhere to be found.My distribution doesn't have it
either...

I installed the base system over the network (through FTP) without any
problems. My parmfile doesn't contain any network parameters since I
wanted to enter them manually.Why did it work for the base installation
and why did it not work after the IPL ?

Can anyone help, please?

The threat is threefold:

a) Lower volumes

b) Lower prices

c) Higher cost per sale

Now - I'm not in charge of Microsoft - that's Steve "take every one of their ideas and 
make
them our ideas" Ballmer's job.  But I'd suggest the next move has to be a radical 
review of
Microsoft's loss-making businesses (that's about everything apart from core OSes and 
suites)
and some pruning.

The xBox loss just doubled to $348 million, for instance.  Business Solutions (Great 
Plains,
bCentral and Navision) more than doubled its losses from $41 million to $93 million.  
MSN and
CE/Mobility also make losses.

Server OS contribution isn't that amazing - the company is held up by client software.

Re: Down time

[Fargusson.Alan]

This is a really good explanation, except that the stepping on other applications 
address space has not been a problem since Windows 3.1 (which is to say it was fixed 
in Win95, and NT).

Most of the system freezes seen these days seem to be due to storage leeks in the OS, 
although I traced one screen freeze to a bad driver.  Oddly enough I found that I 
could get out if that particular freeze by hitting CTRL-ALT-DEL twice, then ESC twice. 
 The first CTRL-ALT-DEL brought up a message on the screen, which I could not see, 
while the second put me in that blue screen with the "press CTRL-ALT-DEL to restart" 
message.  Pressing ESC put me back in Windows, with the screen unfroze, and the second 
ESC got rid of the message in Windows.

I think it's partly due to hardware.  S/390 hardware is very
reliable/stable.  I think it's partly due to software.  In the "PC" arena,
and by PC I mean Windows/Intel, software seems to be released before it
should without the proper testing.  My experience
with S/390 has been that because such critical applications are running on
the Mainframe, having an outage is not an option,
therefore extensive testing is done.

The attitude is a little different.  Mainframe'ers seem to be more thorough
in their work.  I think the attitude among some, not all,
in the PC arena is that if all else fails, just do a CTRL+ALT+DEL.  There
are "acceptable" risks.  Incomplete testing, etc.

>From what little I understand about the architecture of Windows compared to
other platforms is that Windows does a poor job of
memory and process management, causing a lot of the headaches.  Not
necessarily Blue Screens...don't really see too many
of those any more, but I hear problems of applications with "memory leaks"
and applications, once in memory, will walk on other
applications' address space...bad, very bad.

Now, my experience with Linux on Intel has been quite favorable.  Once all
the proper drivers for the particular hardware has
been properly configured, it will run like a champ for months if not years
before a reboot...er, I mean IPL.
