Re: Down time
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. -Original Message- From: Daniel Casey [mailto:[EMAIL PROTECTED]] Sent: Monday, February 03, 2003 7:28 AM To: [EMAIL PROTECTED] Subject: Re: Down time 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.

Re: eWeek Article: Microsoft Warns SEC of Open-Source Threat
To the extent the open source model gains increasing market acceptance, sales of the company's products may decline, the company may have to reduce the prices it charges for its products, and revenues and operating margins may consequently decline, it said. 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: Debian install problem
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 commitment for zSeries, S/390®, z/OS, and OS/390® dates back to 1973. http://www.ibm.com/servers/eserver/zseries/zos/security/systemintegrity.html 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...] 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.. 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. 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. -- Cheers John.

CIO Today Article: The State of Samba
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. http://www.newsfactor.com/perl/story/20673.html Very cool, considering this involves a bit of effort today.

Re: Debian install problem
Maciek, 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 ? 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. My distribution doesn't have it either... 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. 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 ? 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.

An Intel Slackware question about the 2.4.x kernels
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. --- Gregg C Levine [EMAIL PROTECTED] The Force will be with you...Always.

Suse 7 kernet 2.4 Packages
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 Amadeus

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.

Re: System administration facility/dirmaint
Hi all, somebody knows whats the diferences between the System Administration Facility and DirMaint? 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 situation is that the people from IBM told us that they will install it after install zvm, i have never heard about it, i read the info about it and i think that it is a replacement for DirMaint, so i want to know the diferences between both, and the experience of use. 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. -- db Thanks. =-) -- Alejandro Leyva Rabinovich.

Re: Suse 7 kernet 2.4 Packages
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.

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

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. __ L.

Re: Utilizing Linked minidisk in a reiser LVM environment
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 Mark Post -Original Message- From: Higgins, Joseph (ECSS) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 5:48 PM To: [EMAIL PROTECTED] Subject: Utilizing Linked minidisk in a reiser LVM environment We recently loaded UDB V8.1.
