Need help with sles9 install using nfs mount
I have set up an installation NFS export for installation of sles9 via NFS, the CDs content have been copied into the special directory structure as documented in the release notes as show here . (mkdir -p installroot/sles9/CD1 # now copy the contents of SLES CD1 into this directory mkdir -p installroot/core9/CD1 # now copy the contents of SLES CD2 into this directory mkdir -p installroot/core9/CD2 # now copy the contents of SLES CD3 into this directory mkdir -p installroot/core9/CD3 # now copy the contents of SLES CD4 into this directory mkdir -p installroot/core9/CD4 # now copy the contents of SLES CD5 into this directory mkdir -p installroot/core9/CD5 # now copy the contents of SLES CD6 into this directory ln -s sles9/CD1/boot boot ln -s sles9/CD1/content content ln -s sles9/CD1/control.xml control.xml ln -s sles9/CD1/media.1 media.1 mkdir -p installroot/yast echo "/sles9/CD1 /sles9/CD1\n/core9/CD1 /core9/CD1" > yast/instorder echo "/sles9/CD1 /sles9/CD1\n/core9/CD1 /core9/CD1" > yast/order) The installation starts properly, I go through and select the dasd to be used, then activate the dasd, then select proper partitioning and software to be installed. The installation formats the dasd the asks for the installation media, I get the following message "Insert 'SUSE LINUX Enterprise Server 9 CD1' URL 'NFS://xx.xx.xx.xx/sles/sles9//sles9/CD1\n/core9/CD1' Error(Media:not attached)" I can type in a new path and select OK or select ABORT or SKIP. I'm not sure what the correct path is? The NFS export is at xx.xx.xx.xx:/sles/sles9.

IBM Open Sources Object REXX
This is interesting. I got an IBM announcement today with a headline of "Software withdrawal and service discontinuance: IBM Object REXX." When I clicked on the link (http://www.ibm.com/isource/cgi-bin/goto?it=usa_annred&on=904-207) it took me to a page that states: Effective January 12, 2005, IBM will withdraw from marketing selected programs licensed under the IBM International Program License Agreement. For details, refer to the Additional information section.

Samba destroys qeth driver II
According to "Device Drivers and Installation Commands - October 7, 2004" (http://www10.software.ibm.com/developerworks/opensource/linux390/docu/lx24jun03dd04.pdf) "PORT_NAME Must be specified for each OSA-Express CHPID in QDIO mode. Identifies the port for sharing by other operating system images. On z900, z800, and on S/390 mainframes the PORT_NAME can be 1 to 8 characters long and must be uppercase. All operating systems sharing the port must use the same PORT_NAME. Example: NETWORK1. This parameter is required only for z900, z800 and S/390 mainframes. For z990 and later mainframes you are advised to omit it." We are running on a z990, so I guess it's not needed. And are the following entries even needed?

Samba destroys qeth driver
We've been fighting an extremely annoying issue where heavy Samba usage causes a loss of network connectivity through an OSA card. Sometimes the problem will correct itself, like after 12 hours yesterday, and sometimes we'll have to manually reload the qeth module. Linux system logs contain absolutely no errors. The Samba logs report a connection loss after the obligatory timeout, but nothing at the time of the outage. I'm now questioning whether we've got this device properly defined. Is 'portname' required for this to function correctly? Where are OSA errors logged to? Some archived postings from 2002 mentioned using addresses which start with denominations of 4 (i.e. 0, 4, 8), is that still correct and a possible source of flaky behavior? /etc/modules.conf ... alias eth0 qeth alias hsi0 qeth ... /etc/chandev.conf ... noauto;qeth0,0x0600,0x0601,0x0602 noauto;qeth1,0x0800,0x0801,0x0802 /var/log/boot.msg ... <4>qeth: loading qeth S/390 OSA-Express driver ($Revision: 1.337.4.22 $/$Revision: 1.113.4.8 $/$Revision: 1.42.4.4 $:IPv6:VLAN) <6> qeth: allocated 0 spare buffers <4>qeth: Trying to use card with devnos 0x600/0x601/0x602 <4>qeth: Device 0x600/0x601/0x602 is an OSD Express card (level: 0551) <4>with link type Gigabit Eth (portname: ) <6> qeth: Broadcast packets will not be echoed back on eth0. <4>qeth: Trying to use card with devnos 0x800/0x801/0x802 <4>qeth: Device 0x800/0x801/0x802 is a Guest LAN Hiper card (level: V445) <4>with link type magic <4> qeth: IPv6 not supported on hsi0 ...

Re: Installing hcp
In this particular case, you don't really need the depmod command, since cpint doesn't have any dependencies on other kernel modules. In general, it's good practice to run the depmod command after making any changes in the /lib/modules hierarchy. What it does is examine each module, figure out what external references it has, and what other kernel modules provide those. This is what allows you to do a "modprobe modname" without worrying about the order in which other modules need to be loaded.

Re: Need help with wget for Yast Online Update
That's the way wget works. It uses the name "index.html" since that is frequently the default on web servers, but what it is _really_ doing is asking the server for a directory listing, and stuffing the output of that into a local file named index.html. I would suggest re-running your command with the "-d" option, and reporting your problem to [EMAIL PROTECTED] You might also want to mention if you're behind a proxy or firewall, if the wget command is from Cygwin or the "native" Windows version H.

Re: Linux Questions
About paging: I know that there has been much discussion here about giving virtual Linux instances too much virtual memory under VM. The issue is that Linux will us all memory for a disk cache. This same problem will occur under VMWare as well. Note that most OSes for x86 do the same caching that Linux does, so they will have the same problem. OSes that I know for sure will have a problem: Linux (of course), UnixWare (all version), SCO Unix (I forget the exact name, and yes SCO has two different and slightly incompatible Unix systems for x86), Solaris (all x86 versions), Windows NT/2000/XP. I am not sure about Windows95, but I think it does not cache. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Richard Troth Sent: Monday, October 11, 2004 1:53 PM To: [EMAIL PROTECTED] Subject: Re: Linux Questions I was pained around two months back when one of our marketing people made a snide comment about running MVS on VM "if you want your performance to drop".

If you have cable television, or if you are a radio hobbyist, you may have heard it before. The "insertion loss" for z/VM is very small, thanks to SIE assist. The "insertion loss" for VMware is much higher, more like it used to be for VM/370, or perhaps worse because the PC-class systems lack that uniform I/O.

Originally, VMware always let the host OS deal with virtual machine memory. Later, VMware would try to pin-down some host storage specifically for virtual machine use, a little like V=R. I run VMware on my newest box at home and only this past weekend flipped the switch to let guests page. (To me, that's the normal way to run a virtual machine!) VMware does have certain limits.

Just like on z/VM, the disk(s) a guest owns can be virtual or attached. Networking too is a lot more like z/VM: "host only" == guest LAN "bridged ethernet" == VSWITCH But your impression is DEAD ON in so far as z/VM and zSeries do a handier job of creating virtual machines. I go back to the "up to a dozen" virtual machines with VMware -vs- "dozens, hundreds, even thousands" of virtual machines with z/VM.

Fw: [LINUX-390] Linux Questions
My understanding is that Appendix A of SG24-4987 ("Linux for S/390") gives,
to my eyes, a good overview of how an S/390 (and now zSeries) differs from
an Intel. Having a huge cluster of Intel CPUs doesn't really give you what
a mainframe can provide.
Look, I don't know where the zSeries stands in number crunching (did
[EMAIL PROTECTED] ever build a VM/CMS version?) but the mainframe is optimized for
single-thread performance. A cluster does NOT give you single-thread
performance... and that's ignoring how you dispatch the workload in a
closely coupled SMP... especially since CPU power of a system doesn't
scale at 1:1 with additional CPUs unless heroic measures are taken to
minimize competition for main memory (I recall some of the tricks used in
the ol' UNIVAC 1100/80 to get around that). The main thrust of the zSeries
is to deal with huge quantities of data which, really, not many other
systems can cope with as neatly.
The real strength of a mainframe is the "take no prisoners" attitude
towards compromising H/W reliability _just_ for throughput-- though I/O
bandwidth and connectivity is _another_ historical advantage of mainframes
(I've no idea how the equation is now stacked given the new "DASD Farms"
like the Shark).
Now if only I had a real mainframe to play with ... though some of the new
pSeries boxes I do have ain't looking too shabby, but then I'm a pSeries
kinda guy.

Please respond to
Linux on 390 Port
I don't know that there's anything specifically comparing Linux on z/VM
versus VMWare. VMWare is one of the virtualization tools IBM is
recommending for their xSeries customers, so it has some merit to it.
Perhaps your local zSeries sales rep will have some thoughts on why VMWare
on Intel is not as good a choice as z/VM on zSeries hardware. :)
>From my perspective, VMWare is not nearly as mature a technology as z/VM.
It doesn't have anywhere near the system management and Linux-enabling
features that z/VM does. The Intel platform is not nearly as rock solid as
zSeries. If you price a full-blown Intel system with redundant everything,
etc., etc., you're getting up into the 10's of thousands of dollars, even
up
to $50K. It only takes a few of those to add up to one mainframe. They'll
knock your socks off on CPU-intensive workloads, of course, but if you have
a lot of mainframe-resident data that needs to be accessed, having a Linux
system on the same box and using HiperSockets is a nice setup for a number
of reasons.
Take a browse through the news articles and press releases at
http://linuxvm.org/Info/l390link.html to get a feel for why other people
have made the move, and see if any of it applies to your circumstances.

Greetings,
Having troubles with promotion of Linux for zSeries in corporate

on
the strengths against an intel platform running VMWARE. There have been
Questions come up about performance, Oracle, How many guests can we put out
there and what kind of performance loss per guest do we get or can we
expect? Just want to justify in spending a quarter of a million on the
hardware and be able to get what we need out of it. Does anyone know of
some
good docs pointing to these answered questions.

Fw: [LINUX-390] Confining a user to the home directory specified in the user record
Yes, and if they want to see more... that's what the refresh button on the
browser is for. (Yes, I'm smirking.)
Around here anonymous FTP is a no-no so if someone needs a file distributed
it goes up under the /HTML tree. (Yes, I'm _that_ lazy, I symlink /HTML to
wherever the document root is on the various systems I've got w/ web
servers, so it's kinda like symlinking /dev/tape to your "regular" tape
drive; before Linux the "real name" of various devices tended to be, well,
rather obscure.)
And I'm aware that any application that has a shell escape (like "less")
won't enforce the restricted shell, so you may need to look at chrooting if
you want _real_ security which symlinking can't get around.
I once wrote an old menu tool that I still use today for my wife; it can
be exec'd from the .profile so that she has a nice
arrow-down-then-hit-enter means of accessing her files (so I can
dynamically generate a menu and enter it so she can _see_ the files she
wants to view). A determined effort to use less' shell escape would work,
of course, since I've not re-written the linux-provided utilities for
security.
I'm thinking though that the web access is the smart way. If you use a CGI
you can look at the requestor's IP address and divine whether the person is
in the right subnet to read the file, too, but this last isn't *really*
security. Never mistake obscurity for security.

Re: Confining a user to the home directory specified in the user record
I thought about that but they wanna be able to less and tail the file. A lot of this is because I am about to go to pam authentication and don't want to add a bunch of short lived local users, or I'd simply add all of the developers to a group and go that way. I just don't want to, and my boss is going 'generic ID? No accountability! Restrict what they can do'. I originally had looked at this: http://www.netsoc.ucd.ie/flash but I didn't get it to make/make install properly. Basically I'm dancing because I've been told to dance. I tried using /usr/bin/rbash as the default shell. Works if you su to a user with that, but not if you ssh, so the rbash thing isn't gonna do it either.

Re: Betr.: Re: lcs0 problems
Hello Robin, I never tried to use the 2216 directly from Linux, there was no need. You either: - run Linux on zVM. Then it is far better to use Vswitch (or guest Lan on older zVM) and leave handling the 2216 to the VM stack. - or you run in LPAR. Then it is like any other LPAR (like zOS) with an LCS device, just like d/t3172. In fact IOCP thinks 2216 is 3172. In all cases you basically have just one connection to the hub. In the past I had the more difficult problems with routing through multiple subnets than with the physical connection itself. We use the first option as there are more Linuxes around than we can get LPARs.

Remember that the 2216 is different from an OSA in that it implemements a hub configuration. The Escon link is quasi a private subnet different from the outside networks.

Also notice the CUADD=1 on the CNTLUNIT which addresses LPAR 1. If you need the multiple LPARs you need to code multiple CNTLUNITs, each with a different CUADD. Remember to also code for those controlunits and devises in the 2216 config!

Re: Betr.: Re: lcs0 problems
Thanks Pieter, i think in our case we have all the parameters set correctly since it works under a z/os tcpip stack. if i had the iocds or 2216 coded incorrectly the lcs interface wouldn't initialize properly under z/os. did you use the 2216 under linux?

Recommended Reading for Head Start on z/VM
We are currently running SuSE Linux 8.1 SP03 in 2 native LPARs on an IBM
2066-002. We have recently enabled an IFL to correct some performance
problems. We now ordered z/VM so we can start running Linux as VM Guests.
We are MVS System Programmers who have learned Linux over the last year. We
know nothing of z/VM. Can anyone recommend any good documentation,
redbooks, or papers for us z/VM challenged newbies that can get us started.
Thanks as always.
Peter
