Re: Interesting perspective
Hymilaya is ZLE or non-stop Windows like kernel. The linux HA is Steeleye SW and HW like this: http://h18004.www1.hp.com/solutions/enterprise/highavailability/dl380/index. html Alan Robertson's linux-ha.org project is the "heartbeat" package that has some kits available; when he was at SuSE I recall we had Apache, and DRDB, with SAP and Oracle in the works. Some of this work also went into the oss.sgi.com "Failsafe" project that Alan and Lars Marowsky-Bree headed up. Most, well really all I know of, our Linux customers use Steeleye, and this is on Dell or IBM too. Solaris customers I have seen here use Veritas. Regards, Jon On 3/17/03 7:49 PM, "Steven A.

I've been using versions of Clark Connect which are built on RHL 7.x, and _that_ does have exim. So, make Postfix the second choice ahead of Exim (for RHL), and use the 7.3 source rpm and build that (unless there are s390 binaries in rawhide). -- Cheers John.

Yes, swat uses basic http authentication: be careful not to use it from someone else's browser!

It takes a lot of work, but it can be > done. Yes, but if you bring clustering into the game, then suddenly cheaper hardwares can become more relieble. The author also forgets that the guests need patching as well. Having all of them as guests on a mainframe, or as separate machines in a farm is not all that different in that respect, because remote-management tools are good enough for the basic tasks. And you can still load the new software to one unused computer in the farm, start it, and then swap-out the bad computer you want to retire. Requires some more hardware, but the hardware is much cheaper, anyway. A bigger problem is that there are simply more machines to patch. This is the basic issue: machines are not patched because their admins (or admin-replacements) don't bother. Admining a system is not a task that requires a special admin (that should be aware of patching). But this is not a technological issue. Note that the technologies for simpler updates (or for pushing updates from the vender) are ways to work around the admin problem . And as usual, the author manages to confuse the different meanings of the word "virtual" (a java/c# VM is not quite relevant here). Anyway, just my unlearned opinion -- Tzafrir Cohen mailto:[EMAIL PROTECTED] http://www.technion.ac.il/~tzafrir/

As always, rpm --help man rpm I have some reservations about the use of non-standard packages and procedures with vendor's releases. If you can keep with one vendor for all your software needs, then you have a fairly simple life keeping track of vulnerabilities from a single source, and you can be confident that when the time comes to upgrade your software, your vendor's procedures have been tested for your environment and will most likely work. When you bring in third-party software to assist with that maintenance, such as webmin, then you introduce the worry that it might do something differently. It might be that webmin is entirely compatible with the way Red Hat, SuSE, Turbo Linux and Debian do things, but I wouldn't bet on it. Perhaps when it's a standard part of the distro (as it is in Debian), it's been coerced to comply. Similarly, you have the question as to how well Postfix will fit into the way your vendor does things. Vendors have their own ways of initialising the system and maintaining its configuration, each is different from the others. Those differences contribute to different people's views as to which distribution is "right for us," and they won't go away. Red Hat, in RHL 7.x, ships one MTA, and that is sendmail. If you don't believe that MTA is suitable for your use, and you are using Red Hat Linux, then I suggest you look at the exim package shipped with Red Hat Linux 8.0. The _only_ reason I suggest this as the first-choice replacement is that it is reasonable to suppose Red Hat will include it in the next release of RHL for S/390 & zSeries, and so any additional maintenance issues will terminate at that time. If you think neither of those suitable, then you really are on your own and you need to allow for the extra maintenance costs associated with your choice, and you should consider hiring or otherwise obtaining competant support for your choice. Now, if you're not using RHL, the points still apply; I'm sure you can translate to one of the other vendors. You are, of course, entitled to mix and match as much as you like, and I've done it for years on my home computers where there are no commercial realities. The premier distro for the mix&match croud has to be Debian, with almost 9000 packages shipped as standard in Woody. -- Cheers John.

Where exactly do you get this error?
What is your hostname?
Sett either 'myhostname' or 'mydomain' in /etc/postfix/main.cf if your
hostname is not a FQDN and/org you wish to use a different one.
('myhostname defaults to the hostname, 'mydomain' defautls to the domain

It is likely that something did not get patched/compiled quite right, or in the proper order, when I did the updates. Also, this is a demo SLES7 installation. Although SuSE originally told us that it's the same code as production only with limited support for a limited time I am beginning to doubt that.

I'm trying to pinpoint where my problem might be (e.g. gcc, glib, libtools, LPRng, PEBCAK). Oh yeah, I've read several f'ing manuals and either don't see the problem addresses or have missed it. Hope that ends the confusion. Steve
Re: LPRng Seg Faulting
Your questions are a little confusing. The title talks about segmentation faults, but you ask about successful compiles. Try reducing the optimization level in the make files to -O1 or even -O0. That has, sometimes, corrected that problem for me, with other packages. What version of glibc are you using? gcc 3.2 is _not_ the distributed version for SLES7. You may want to post the gcc command for the module that is segfaulting. Sometimes options/switches that work fine on Intel Linux are not appropriate for Linux/390.

Yeah. Scared the dickens out of me the first time we tested it with a system that mattered -- I kept thinking "if this thing burps on one of the production disks, we are *dead meat*".

Re: Interesting perspective
I think only the big user who has a sysplex can really keep up something running all the time. You can do rolling IPLs on an MVS sysplex, and install maintenance or a new release of the operating system without shutting the whole sysplex down. Of course us having an MP3000, I have no real experience with this. I did VM for several years until we got rid of it, and yes, I agree, you have to IPL for a lot of changes.

Re: Interesting perspective
Perhaps the writer was referring to a Sysplex where multiple LPARs are running z/OS with a coupling facility in the middle. Using MQ Series clustering, DB2 Data Sharing, VSAM RLS, VIPA, and the like, you could switch workload from one image to another, IPL the image you drained, and migrate the workload back. It takes a lot of work, but it can be done. On Monday 17 March 2003 16:35, you wrote: > I agree. The writer is wrong.

Hopefully someone knows if my coding is correct, or why the devices defined don't come up online. Maybe this is normal. I don't have my Linux1 Lpar running. We don't have VM. I did notice that the E00 devices have the PARTITION keyword, and the D00 devices don't. I didn't notice that before today when I looked at the IOCP deck I generated on Friday.

Re: getting to samba
Speaking from my recent experience with Samba, I also did not have to compile Samba. But I did have to take the RPMs I got for the particular distribution I was on and install them. This was accomplished after I acquired the latest tarball for Webmin tarred it and installed it. I then used Webmin to both install the Samba RPM and then access SAMBA then SWAT from the server page.

Re: Postfix Install problem
Actually, a third choice proved to be backreving Postfix to postfix-1.1.7-6.src.rpm which allowed a rebuild requiring more of the standard RPMs from the MCS mirror site for this distribution. I guess it would be safe to say that progress on s390 will tend to lag that of i386. Now it appears that I have my hostname specified incorrectly. the rebuilt postfix rpm needs it to be a FQDN like cofr3.linuxvm.gov . Perhaps one of you would be kind enough to direct me as to how a change like this could be made? Thank you in advance for your time. >>> [EMAIL PROTECTED] 03/13/03 04:51PM >>> On Thu, Mar 13, 2003 at 03:58:06PM -0500, Kenneth Illingsworth wrote: > The last package that I needed to install Postfix onto a RH v7.2 i > virtual s390 machine was something called 'alternatives'.

The "alternatives" mechanisms was invented by debian and adopted by Mandrake (do you use their packages? Or is it a later version or RH?) It is aimed at solving file-conflicts between packages. For example: both sendmail and postfix have /usr/sbin/sendmail . And each has its sendmail(8) man page in /usr/share/man/man8/sendmail.8.bz2 (IIRC) This means that you can't have both sendmail and postfix installed on the same system at the same time. Even though they don't conflict most of the stuff (actually they have some other file conflicts). So /usr/sbin/sendmail becomes a symlink to /etc/alternatives/sendmail . The alternatives program allows several candidates to register themselves for it (e.g: /usr/sbin/sendmail.postfix) . There are actually "groups" of such links, because if you want postfix's sendmail to be /usr/sbin/sendmail you probably want its man page as well. So the way I see it you have two options: 1. drag the alternatives package in. Hope that it doesn't depend on two much. IIRC Mandrake (at least in earlier versions) had the alternatives as part of the package rpm (yuck!). 2. You probably don't need such alternatives for your specific site, so: remove any trace to alternatives from the package. Maybe you simply need to add a number of symlinks to the %install scripts and slash some lines from the %post and %preun scripts. -- Tzafrir Cohen mailto:[EMAIL PROTECTED] http://www.technion.ac.il/~tzafrir/

Re: getting to samba
Root for system. It uses whatever ID has UID 0 for update authority. Any other usable ID should give you query-only access to some of the screens. I have systems that use local domain authorization (smbpasswd), and remote domain authentication (SECURITY=DOMAIN with a PASSWORD SERVER), and it works the same for both. > -Original Message- > From: Daniel Jarboe [mailto:[EMAIL PROTECTED] > Sent: Monday, March 17, 2003 1:30 PM > To: [EMAIL PROTECTED] > Subject: Re: [LINUX-390] getting to samba > > > > > > bad auth... > > > Use root and your root password. > > that's what i used > > root for the system, or root for smbpasswd?

Re: reset a computer
OK, so if I read this correctly, you want to boot the system, have it do some custom setup if it hasn't already been done, and then record the fact that your setup has been done for future boots. At some point, you want to be able to revert to the master configuration and re-do the custom setup in a possibly different way on demand. Is that what you're shooting for? If so, then you need to do some work in both CMS and Linux. Your Linux systems should have only a private writable 191 and a link to a shared R/O 192 that initially IPL CMS and use CMS facilities to define the basic configuration of the virtual machine. The PROFILE EXEC on the 191 should test for a LINPROF EXEC on the 192 (which will be accessed as D automagically by CMS, execute it as the "common" configuration part of the Linux setup for the parts of the Linux virtual machine configuration that are the same for all the guests, then test for EXEC D that contains CP and CMS commands that make this virtual machine unique at the VM layer. The EXEC should write two files on the A disk (one indicating that the basic setup has been performed (call it CONFIG COMPLETE), and the second file should contain a list of Linux commands that need to be executed after booting to perform the Linux half of the configuration. The EXEC should terminate by IPLing Linux from the appropriate boot device. On the Linux side, you will have to ensure that the CMS filesystem utility is available in the boot partition, and in the setup for init, a step is performed to copy the the file containing the Linux commands from the CMS A disk to a known location in the Linux guest. Suitable /etc/init.d entries should be made to read and execute the commands in the file as part of the boot. Your EXEC can check for the existance of the CONFIG COMPLETE file on the A disk and react accordingly. If you want to force reconfiguration, delete CONFIG COMPLETE and your EXEC can go through the setup steps and rewrite the CONFIG COMPLETE and Linux command files when done. If necessary, the EXEC can DDR over a master copy of the base Linux image and start from there.

Re: Patch available to add LOADPARM support to ZIPL
John, In general, they don't have the power to veto contributions. Since the good folks in Boeblingen are the architecture maintainers, they have a _lot_ of influence. That's true of every kernel developer that's responsible for a certain area. Overriding them is done reluctantly, but it has been done in the past, and it will be done again in the future. There's just got to be a really good reason for it.

Re: Patch available to add LOADPARM support to ZIPL
But so does the HMC I/O handler and the shutdown signal. The QDIO driver uses the undocumented SIGA instruction but it's there. There needs to be a mechanism where code (under the GPL) can be entered into the development stream without worrying about "lawyers at 10 paces". At the moment if the IBM team get things from the canonical source (i.e. kernel.org) they have no problems in using it and there are no questions asked. There seems to be a somewhat artificial distinction being drawn between this method and some form of direct donation. This is something that IBM management now needs to address: we're either doing the open source thing or not. No one's been burned yet so let's start getting a little more adventurous. -Original Message- My guess? I haven't a clue, but I'd venture to say...never. It uses undocumented (SERVC) facilities and I don't know if IBM "legal" would look kindly on that.

Cheers,,,Steve -Original Message- From: Ferguson, Neale [mailto:[EMAIL PROTECTED] Sent: Monday, March 17, 2003 7:53 AM To: [EMAIL PROTECTED] Subject: NGPT - Vale >From the NGPT developers... On behalf of the NGPT team, we would like to announce a change in direction for the Next Generation POSIX Threading (NGPT) project. As many of you may know by now, a new POSIX threading library NPTL (http://people.redhat.com/drepper/nptl-design.pdf) is now available for Linux and we don't want to split the community to choose one over the other. The Linux 2.5 kernel has added many new features in the areas of Scheduler, POSIX signal handling, clone() improvements and futexes that make highly scalable and performing threads a more viable solution in Linux. With this in mind, we have decided to stop adding new functionality to the NGPT pThread library and will go in pure support mode. We will provide full support for the existing NGPT releases and to those who have incorporated NGPT in their current releases, and work to bring solutions for other threading requirements to the NPTL community for discussion and dispositioning. Currently, using Glibc-2.2.x, NGPT can be used as Linuxthreads replacement library. However, NGPT will not be supported under Glibc-2.3. Our original goal was to make threading in Linux more scalable and POSIX compliant, and it seems clear that NPTL has addressed such issues quite well. We will continue focus and working in the direction of improving overall threading performance in Linux. In summary, we feel that this decision is the best way to support the community for the long term. We would also like to participate to improve threads scalability and POSIX compliance for threading package in Linux. If anyone has any questions or concerns about this decision, please email us or the NGPT mailing list at [EMAIL PROTECTED] We will be happy to answer any questions or discuss these changes in more detail.

Re: synchronizing user directories
As David's pointed out, DIRMAINT and CSE let you do this fine. In fact you can do this without CSE, but then you need to develop your own locking mechanism to make sure that the same guest (assuming it has the same dasd on each side) isn't running in both places simultaneously. Having two guests with write links to the same disk is a recipe for disaster. Adam

Re: synchronizing user directories
Yes. Look into a VM feature called Common System Extensions (CSE). It takes some planning to do this, but as long as both VM systems can directly share disks, that's exactly what CSE was designed to do. DIRMAINT has support for syncing user directories in CSE complexes, and if the directory is not on the IPL volume, you can share it between systems. Warning: this is NOT trivial to set up. It is also not very well documented any longer -- the information is there, but is scattered. There is some discussion of CSE in the CP Planning manual, but you would be well advised to find a copy of Alan Altmark and John Fransicovich's recent presentation on VM clustering techniques from the z/VM Expo or WAVV to explain in more detail what is involved. -- db David Boyes Sine Nomine Associates > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Tim-Chr.

Re: getting to samba
Ralph, That's what he's talking about. SWAT has it's own built-in web server, and it uses inetd to listen on port 901 for any requests. That means that /etc/inetd.conf has to tell inetd to start SWAT when it gets a request on that port.

Re: using lcs module with two type of adapters?
Abdullah, It should be possible, but not by trying to load the module twice. You'll need to provide the parameters for both interfaces when the module is first loaded. The "Linux for S/390 Device Drivers and Installation Commands" book at http://www10.software.ibm.com/developerworks/opensource/linux390/docu/l390dd 03.pdf should give you some ideas how to do this.

Postfix Install Problem (continued)
My apologies in advance if this already made it to the listserv. I have reason to believe that it did not make it though since we are using an old version of GroupWise (v5.5) running on evan an older version of Novell (V4.11), and the action status of 'pending' does little for my confidence. Hence my sudden and extreme interest in Postfix as a replacement MTA. Here is what I tried to send to the existing thread: - Choice 2 below sounds good. Unfortunately, I do not know where the %post and %preun scripts are. Nor can I seem to get the find command to zero in on them. Can I assume that they can be edited with vi? Additinally, my standard way to uninstall a package is to do so from within the package tree in Webmin. However, the 'alternatives' package is not contained within that list! The man pages do not indicate such, but I suspect that there is an unistall parameter like RPM --uninstall available?

The way I see it you have two options: 1. drag the alternatives package in. Hope that it doesn't depend on two much. IIRC Mandrake (at least in earlir versions) had the alternatives as part of the package rpm (yuck!). 2. You probably don't need such alternatives for your specific site, so: remove any trace to alternatives from the package. Maybe you simply need to add a number of symlinks to the %install scripts and slash some lines from the %post and %preun scripts.

If so, uncomment that line and run "/etc/init.d/inetd restart", then try again from a browser. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061 "Noll, Ralph" <[EMAIL PROTECTED]>@VM.MARIST.EDU> on 03/17/2003 08:45:47 AM Please respond to Linux on 390 Port <[EMAIL PROTECTED]> Sent by:Linux on 390 Port <[EMAIL PROTECTED]> To:[EMAIL PROTECTED] cc: Subject:[LINUX-390] getting to samba how do i get to samba on kernel 2.2.16 i do ipaddress:901 i am on kernel 2.4.17 on s390 can you help??

synchronizing user directories
Hi, well, I know that my question is more VM related, that linux related, but anyway I have two VMs and want to run Linux-guests on both of them. My idea is that I can start a guest on both sides, so I have to make an entry in the user directoies on both VMs... so far, so good. Is there a possibility that I only have to make the appropriate entry once and that the two user directories are synchronized automatically? I think of dirmaint or something else... thx - Tim -

NGPT - Vale
>From the NGPT developers... On behalf of the NGPT team, we would like to announce a change in direction for the Next Generation POSIX Threading (NGPT) project. As many of you may know by now, a new POSIX threading library NPTL (http://people.redhat.com/drepper/nptl-design.pdf) is now available for Linux and we don't want to split the community to choose one over the other. The Linux 2.5 kernel has added many new features in the areas of Scheduler, POSIX signal handling, clone() improvements and futexes that make highly scalable and performing threads a more viable solution in Linux. With this in mind, we have decided to stop adding new functionality to the NGPT pThread library and will go in pure support mode. We will provide full support for the existing NGPT releases and to those who have incorporated NGPT in their current releases, and work to bring solutions for other threading requirements to the NPTL community for discussion and dispositioning. Currently, using Glibc-2.2.x, NGPT can be used as Linuxthreads replacement library. However, NGPT will not be supported under Glibc-2.3. Our original goal was to make threading in Linux more scalable and POSIX compliant, and it seems clear that NPTL has addressed such issues quite well. We will continue focus and working in the direction of improving overall threading performance in Linux. In summary, we feel that this decision is the best way to support the community for the long term. We would also like to participate to improve threads scalability and POSIX compliance for threading package in Linux. If anyone has any questions or concerns about this decision, please email us or the NGPT mailing list at [EMAIL PROTECTED] We will be happy to answer any questions or discuss these changes in more detail.

add new dasds
hi list, We recently installed Suse 7.0 in our H30 machine (lpar mode). During installation we specified only two dasds using the "insmod dasd" command. But now we want to add some more dasds to the system. How to do this. thanx in advance. janaks.
Re: using lcs module with two type of adapters?
the kernel is 2.4.7 They -WERE- the typical erros when you load a module about IRQ and stuff. I was trying to pass him the addresses but it fails. thanks to your answer I figured I do not have to do insmod anymore. now all I do is ifconfig eth0 and it works. Now my question is how important arethe following lines in modules.conf for the adapters configuration at boot: alias eth0 lcs alias tr0 lcs --- Vic Cross <[EMAIL PROTECTED]> wrote: > On 17.03.2003 at 18:10:15, Abdullah Al-humaid > <[EMAIL PROTECTED]> wrote: > > > Can I use the same LCS module with two type of > > adapters ( TR, EN)? we have a machine running > suse7 > > and we are trying to start the ethernet adapter > while > > the TR adapter is up using the same module but it > wont > > load. > > Yes, you can do this, but the module will load only > once.

Yes, you can do this, but the module will load only once. The LCS module will pick up all available adapters that have been configured to the channel device layer (chandev). This assumes a 2.4 kernel; if your system is on a 2.2 kernel, the parameters you specify to the module when it loads must specify all of the adapters you want. If you can tell us a little more about the error messages you are seeing, we will be able to give you some more information. Cheers, Vic Cross

In the ISP/ASP redbook, we were only partly joking when we suggested that you should draw network diagrams of your penguin colony without showing z/VM, for certain audiences. As Mark said earlier, replace the "z/VM TCP/IP" label with one that says "Router", and the "HiperSockets" label with one that says "Ethernet". It is not totally accurate, but from the point of view of the network guys it should be good enough to convey what you want. When everything's working and they want to look inside the zSeries cabinet for where the network kit is, *then* sit them down and fill in the gaps. ;-) > I'm also starting to appreciate how good it will be when I get z/VM v4.3 and > can use the broadcast ability of its QDIO guest LANs. Meanwhile, I'll see > what the network blokes can do for me. Unless you have an application that specifically requires broadcast, you won't really notice the difference. The ARP "simulation" that the Guest LAN code provides makes a Guest LAN look enough like Crashernet that most applications work just fine. Cheers, Vic Cross
using lcs module with two type of adapters?
Can I use the same LCS module with two type of adapters ( TR, EN)? we have a machine running suse7 and we are trying to start the ethernet adapter while the TR adapter is up using the same module but it wont load.
