Re: Red Hat 7.2 - install by tape?
can someone tell me what it means to not be able to insmod the qdio/qeth driver? As I understand it ... There are a number of ways to do networking on Linux on zSeries. Ususally the driver is a Linux module. Linux modules are often added to the Linux kernel via the insmod command. In order to insmod a module, it needs to be compatible. If the module is built at a different level than the kernel and contains no unresolved external symbols, the module can still be insmoded with the -f (force) flag. If there are unresolved symbols (data or code areas referenced, but not present), then the module simply will not insmod, and therefore cannot be used. This is the case with an upgraded Red Hat 2.4.9-31 kernel and the qdio/qeth modules at the 2.4.9-17 level available on IBM developerWorks. Therefore, if you want to upgrade the kernel, you cannot use the qdio/qeth drivers which are used for the OSA-Express in QDIO mode (TYPE=OSD) and for hipersockets. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Re: Red Hat 7.2 - install by tape?
Ken, You can insmod the IBM drivers with the new kernel. We're doing it, and it works fine. You have to use the '-f' option though, but only because SuSE I was talking Red Hat, not SuSE. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Re: Red Hat 7.2 - install by tape?
I am new to Linux (and UNIX) but need to do a proof-of-concept for using Linux on S390 for file and print serving. I was planning to use Red Hat 7.2 Be warned - using the GA code, the kernel will oops when you first write to a Samba share. You will want to apply the updates (However, if you apply the updates you will not be able to insmod the qdio/qeth driver, so you must be using a different network driver - hopefully this issue will be resolved soon). GA code is at: ftp://ftp.redhat.com/pub/redhat/linux/7.2/en/os/s390/ Updates are at: ftp://ftp.redhat.com/pub/redhat/linux/updates/7.2/en/os/s390/ Install GA, download all update RPMs to a directory and do rpm -Fvh * Then modify zipl.conf to pick up the new kernel # cd /etc # diff zipl.conf zipl.conf.orig 5c5 image=/boot/vmlinuz-2.4.9-31 --- image=/boot/vmlinuz-2.4.9-17 # zipl reboot. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061

Re: OK who messed with the redbook?
Hi list, I got the reply from the ITSO; the book is not going to be renumbered to -01 as the changes do not meet the criteria: For all - normal practice that is documented is that if 10%+ changes it is a new version #. Otherwise not so. Remember that our site shows a last revised date and there is also a Summary of Changes - if you choose. And whomever made the changed did not choose to include a Summary of Changes. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Re: OK who messed with the redbook?
Can I ask you to state publically and explicitly: what were the reasons given for the removal, by those who supported this action? We can surmise what they might be, but it would be interesting to hear... No. I don't recall details, and I've stuck my neck out as far as I care. Let's move on and get back to the fun stuff (gotta get this hsi0 working again). -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Imprints - worth the effort?
Hi list, Has anyone used imprints successfully on Linux on zSeries (imprints.sourceforge.net)? It sounds like a great concept of being able to download signed Windows printer drivers to a Samba machine for simple printer adds, but I'm not sure how mainstream/solid this project is. Thanks. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061

Re: Separate Group for each User
Hi, I've been working with some of these issues both on Linux and from Windows via Samba. This thread helped motivate me to tie up a few loose ends and write it up: In our little production Samba server, we leave the default group of users, but add team members to another group. This script adds new users using the group 'zntc' which of course must first exist: - #!/bin/bash # script to add a user to /etc/passwd and /etc/smbpasswd with the group zntc # use the Windows user name and type the Windows password 4 times for # password-free network drive maps # arg 1 is the user name if [ $# != 1 ]; then echo Usage: `basename $0` username else useradd -g users -G zntc $1 passwd $1 mkdir /home/$1 chown $1.users /home/$1 smbpasswd -a $1 fi - To share files r/w in the group on Linux we do the following: -Set umask 002 in /etc/profile (instead of umask 022) -Set group ownership of the directory to be shared (chgrp zntc /zntc) -Set the group execute bit on the directory (chmod g+s /zntc) To do the same for Samba we define the share [zntc] as follows: path = /zntc read only = No force group = +zntc create mask = 0664 directory mask = 0774 inherit permissions = yes Then group members modify each other's files, both on Linux and via Samba, but non-group members can just read. Also, I believe users can belong to multiple groups with the same behavior - I just haven't tested this part. I know this model allows users r/w to other user's homes - if this is a problem you could simply not create home directories or use the Red Hat model of each user in their own group - neither of which is optimal. I guess the optimal solution would be, in addition to having group ownership inherited, to have a umask inherited under directories. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Two Linux on zSeries redbooks residencies in April and May
Hi, You might be interested that there are two Linux on zSeries redbook residencies planned in Poughkeepsie, NY: Linux on zSeries and S/390: Systems Management, 15 April - 17 May. See: http://publib-b.boulder.ibm.com/residents.nsf/IntNumber/LS-K302?OpenDocument Linux on zSeries and S/390: Application Development, 22 April - 24 March. See: http://publib-b.boulder.ibm.com/residents.nsf/IntNumber/LS-K301?OpenDocument If you are qualified, the ITSO (redbook group) will pay travel and living expenses, but not salary. See the Web sites for all the details. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
ISP/ASP redbook is published!
Hi list, The redbook Linux for S/390 and zSeries: ISP/ASP Solutions, SG24-6299 was published today. It is on the Web at: http://www.redbooks.ibm.com/abstracts/sg246299.html -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
Re: SAMBA help
So, read the docus;-) Try www.samba.org if you don't have them locally. And don't forget, the book Using Samba was donated to the open source community by O'Reilly** See http://www.oreilly.com/catalog/samba/toc.html Also, with later Samba releases, the whole book is available through swat. Just this makes setting up swat worth the small effort. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061 ** It's nice when an organization puts freely downloadable, decent books on the Web (Oh yes, the IBM ITSO will put out more than 200 free books this year - a small reminder for one of the many facets of IBM's support of the open source software community :))
Linux on the Mainframe BOF at LinuxWorld Expo, Jan 31, 2002, NYC
Hello list, Carlos Ordonez and I volunteered to host the following Birds of a feather (BOF) - well buried on the LinuxWorld Web site: Linux on the Mainframe Thursday, January 31, 2002 6:00PM - 7:30PM Location: ???, Jacob Javits Convention Center, New York, NY The mainframe (S/390 or IBM e-server zSeries) is getting more recognition as a viable Linux platform. Some would argue it is actually helping Linux become accepted in the enterprise. This BOF will bring together professionals using Linux on the mainframe, both under z/VM and in LPARs, or those who are simply interested. Audiences: All LinuxWorld Attendees BOF Leader(s): Carlos Ordonez, IBM Corporation Mike MacIsaac, Team Leader, IBM Corporation If you're attending the conference, please plan to come to this BOF. If you're not attending but have an interest, a general admission ticket is just $10 before Dec 27. If you want to also attend the talks, its more $$ but fairly reasonable. See http://www.linuxworldexpo.com There is no formal presentation as no equipment will be supplied. I was planning on digging up a questionnaire similar to the one that Neale Ferguson has distributed and summarized at other conferences. This will simply be an open session where people can meet each other and share their opinions. I was thinking of proposing the following topics: 1) The wisdom of IBM OCO network modules 2) The productivity of vi versus Emacs 3) Politics 4) Religion 5) Your current health status No - just kidding! :)) That might not lead to a productive session. More productive might be better focused topics such as: 1) How you plan to use Linux on zSeries in production 2) How you *are* using Linux on zSeries in production 3) Topics and areas that need to be addressed in 2002 4) Values you get from Linux on zSeries versus other platforms 5) Anything else except 1-5 from the first list Hope to see you there. Happy holidays everyone. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
ISP/ASP redpiece-redbook, Redbook plans for 2002
Do we have any idea when this is going to be available? It is still listed as a redpiece. This year, the editors promised me. It was ready to go Nov 1, and I could gripe about why it was held up, but that's just IBM's dirty laundry. Though it hasn't been updated on the Web since Oct 26th, the changes will be quite minor. I apologize for the delay, but I chose not to take this battle on. While I'm here, let me mention next year's plans for Linux redbooks. Those *proposed* to be funded are: Linux on zSeries and S/390: Application Development Linux on zSeries and S/390: Systems Management Linux on zSeries and S/390: HOWTO Anthology Use of Virtual Servers for Large Scale Linux on zSeries Deployment So watch for residencies to be announced. The HOWTO anthology is somewhat of a new concept - it will be a compendium of (8-10?) papers release during the year and published as a redbook at the end of the year. This is designed to enable timely publishing of specific topics. So if you can't get away for a residency but still would like to contribute to the community through IBM and the ITSO, consider writing and contributing a paper (topic and quality appropriate, of course). On a personal note, it looks like I'll be moving out of the ITSO on to another job at IBM POK. It's been a wild ride here and I've enjoyed meeting and working with many of you on this list. At least for the first three months of 2002, I'm hoping to button up the code associated with the redbook Open Source Software on z/OS and OS/390 UNIX, SG24-5944 (remember OS/390 UNIX? :). I'm not sure who will be leading the projects next year, but I will still be involved with them. So if you want to volunteer a paper, let me know for now. -Mike MacIsaac, IBM [EMAIL PROTECTED] (845) 433-7061
