03/2/2002 - Florian LaRoche of Red Hat reported a new version of their 64-bit beta had been uploaded. He listed some of the changes:

• kernel contains:
  • GPL lcs driver is now included
  • fix for samba problems
  • order2-3 patch from IBM
• many bug-fixes for the installation
• all rpms are now compiled with the newest binutils patch from IBM
• htdig/squid plus some other rpm updates

03/13/2002 - Sergey Korzhevsky shared his success in getting tape support to work to write a Linux/390 IPL tape. Most systems have 2 special character files and one special block file defined for each "set" of tape devices, e.g., rtibm0 (rewinding character tape 0), ntibm0 (non-rewinding character tape 0) and btibm0 (block tape 0), rtibm1, ntibm1, btibm1, etc. The entries in /dev (on a Red Hat 7.2 system) look like this:

crw-------    1 root     root      37,   0 Sep 23 11:25 rtibm0
crw-------    1 root     root      37,   1 Sep 23 11:25 ntibm0
brw-------    1 root     root      37,   0 Sep 23 11:25 btibm0


crw-------    1 root     root      37,   2 Sep 23 11:25 rtibm1
crw-------    1 root     root      37,   3 Sep 23 11:25 ntibm1
brw-------    1 root     root      37,   1 Sep 23 11:25 btibm1


crw-------    1 root     root      37,   4 Sep 23 11:25 rtibm2
crw-------    1 root     root      37,   5 Sep 23 11:25 ntibm2
brw-------    1 root     root      37,   2 Sep 23 11:25 btibm2

1. insmod tape390 tape=<address>
2. cd /dev; mknod ntibm0 c 254 1
   Driver uses major number 254 (in my case)
3. mt -f /dev/ntibm0 rewind
4. dd if=image of=/dev/ntibm0 bs=1024
   write the kernel image to tape
5. mt -f /dev/ntibm0 eof 1
   write an EndOfFile mark
6. dd if=parmfile of=/dev/ntibm0 bs=1024
   write the parmfile to tape
7. mt -f /dev/ntibm0 eof 1
   write an EndOfFile mark
8. dd if=initrd of=/dev/ntibm0 bs=1024
   write the ramdisk image to tape
9. mt -f /dev/ntibm0 eof 2
   write EndOfFile mark twice - for sure :)
10. mt -f /dev/ntibm0 rewind

03/13/2002 - Neale Ferguson reported SuSE's announcement of their 64-bit Linux/390 distribution's anticipated GA date: the beginning of May, 2002.

03/14/2002 - Dave Jones discovered this IBM press release pre-announcing the general availability of mySAP.com for Linux for zSeries (64-bit) only, on May 31st of 2002. It includes a testimonial from Burghart Pohler, data center manager of Alcatel SEL AG, on the ease of installation and the results of their performance tests. (No numbers were given, of course. This is a press release after all.)

03/14/2002 - James Melin reported that he was unable to boot Linux/390 in an LPAR off a PAV volume on his Shark (IBM ESS) box. He was able to use PAV volumes from Linux/390, just not boot off them. He closed his note with this comment:
"The reason that PAV volumes for boot volumes seem to work under VM is that VM is managing the I/O for the VM guest and it knows enough to make the PAV volumes interoperable. It appears to be only when Linux is native in an LPAR, that the PAV volume as a boot media fails."

03/15/2002 - In response to some people having problems with Samba on Red Hat's 7.2 system, David Sainty of Red Hat posted this comment:
"I would suggest trying my patched samba package set, available at: ftp://people.redhat.com/dsainty/s390/
These packages should be identical to those you have already, with the exception that there is an added patch to disable use of the dnotify system call."

03/15/2002 - In response to someone who was having problems, Carlos Ordonez gave a pointer to an IBM Redbook, "Technical Introduction: IBM eserver zSeries 800, SG24-6515-00", that talks about setting up an OSA Express Fast Ethernet card in QDIO mode, specifically with SuSE Linux Enterprise Server 7.2. The excerpt he quoted from page 123 of the book describes the problem and the workaround:

The installation procedure for the SuSE LINUX 2.4.7 distribution has a minor bug that prevents the automatic setup QDIO mode. However, this setup can be performed manually. To do this, select option 0 (no network). For security reasons, set up the root temporary password first:

   passwd root

   echo 'noauto ' >>/proc/chandev
   echo 'qeth0,0x0e30,0x0e31,0x0e32,0,0 '>/proc/chandev
   echo 'add_parms,0x10,0x0e30,0x0e32,portname:RPTRFET1 ' >>/proc/chandev
   insmod qdio
   insmod qeth
   ifconfig eth0 10.0.0.1 netmask 255.255.255.0 broadcast 10.0.0.255 up
   /etc/rc.d/inetd start
   /etc/rc.d/portmap start

   mkdir /mnt/newroot
   mount /dev/dasda1 /mnt/newroot
   cd /mnt/newroot/etc

• In modules.conf, we changed:

     alias eth0 off

  to:

     alias eth0 qeth

• In chandev.conf, we added the following lines:

     noauto
     qeth0,0x0e30,0x0e31,0x0e32,0,0
     add_parms,0x10,0x0e30,0x0e32,portname:RPTRFET1

   echo 'alias eth0 qeth '>>modules.conf
   echo 'noauto ' >>>chandev.conf
   echo 'qeth0,0x0e30,0x0e31,0x0e32,0,0 '>>chandev.conf
   echo 'add_parms,0x10,0x0e30,0x0e32,portname:RPTRFET1 ' >>>chandev.conf

03/15/2002 - Samy Rengasamy reported a problem he was having trying to get the Berkely DB 4.01 package to build in his system. According to the support folks he contacted, "The problem is that Berkeley DB does not include assembly language mutexes for the s390 architecture, and Linux POSIX 1003.1 pthread mutexes aren't sufficient for DB as they do not support locking between processes, only between threads in a single process." In response, Neale Ferguson submitted this post:
"Try this for a spinlock. It's similar to something I coded when I ported Postgresql a couple of years ago. (Have we been doing this for > 2 years already?)"

03/18/2002 - During a discussion about the differences between the "cdl" and "ldl" Linux/390 DASD layouts, Volker Sameske of IBM provided the following information:
"The Linux partition table in cdl case is hidden in a 390-like volume table (VTOC) in the second track.

"And you can specify a block on an ECKD DASD by specifying cylinder/head/sector or cylinder/track/block. Head and track are equal here, like sector and block."

ldl:
(cyl/trk/blk)
(0/0/1): 1st IPL record  - size: blocksize
(0/0/2): 2nd IPL record  - size: blocksize
(0/0/3): volume label    - size: blocksize (LNX1)
followed by the one and only partition

cdl:
(cyl/trk/blk)
(0/0/1) boot code      - size: 28 byte
(0/0/2) boot code      - size: 148 byte
(0/0/3) volume label   - size: 84 byte (VOL1)
(0/0/4) 1st IPL record - size: blocksize
(0/0/5) 2nd IPL record - size: blocksize (only if needed)
...
(0/0/n) empty          - size: blocksize

(0/1/1) format 4 DSCB  - size: 140 byte (describes VTOC itself)
(0/1/2) format 5 DSCB  - size: 140 byte (contains free space info)
(0/1/3) format 7 DSCB  - size: 140 byte (omitted for small disks)
(0/1/4) format 1 DSCB  - size: 140 byte (describes 1st partition)

http://biz.yahoo.com/iw/020318/039428.html

03/19/2002 - Axel Wirbser of IBM reported the following updates to the DeveloperWorks web site:

• Recommended gcc 2.95.3 bug fixes
• Recommended 2.4.7 "Order 2 allocation relief" patch who no longer breaks other architectures and compatible with the timer patch on the same kernel.
• Experimental 2.4.17 "Order 2 allocation relief" patch who no longer breaks other architectures and compatible with the timer patch on the same kernel.

03/20/2002 - In response to a comment about native Linux performance measurement tools to look at a sendmail problem Alan Cox posted this comment:
"top will show you process data
sard will show you disk statistics providing your vendor ships that feature (look in proc/partitions and you should see stuff like..
22 64 80043264 hdd 23376 219526 1943138 1722140 14309 266197 2244104 2311340 0 801060 4033700 )
vmstat will provide paging rate information (especially handy is vmstat 1)

Sendmail defaults to stopping listening based on load average, the value it picks may be a bit low for the S/390 i/o v cpu.

Look in /etc/sendmail.cf for

      # load average at which we just queue messages
      #O QueueLA=8

      # load average at which we refuse connections
      #O RefuseLA=12

03/20/2002 - In response to a query about using PAM to provide Linux authentication and resource control through to the LDAP server that is part of RACF, Franco Masone replied "A friend of mine helped me to write a little PHP3 script to test LDAP access from Linux/390 to OS/390 LDAP/RACF. Write to me directly if you want the code." He further commented "Our objective was to demonstrate that it's possible to validate user and pwd to RACF without duplicate users or to re-invent the wheel." That code is now available at:

03/25/2002 - Scott Courtney posted a link to a ZDNet Tech Update that looks at Linux/390. The writer was a little shy on S/390 background, particularly VM, so Scott said he sent him an email with some more information and a few URLs to look at as well.
http://techupdate.zdnet.com/techupdate/stories/main/0,14179,2857452-1,00.html

03/26/2002 - In response to a question about ways to "push" maintenance to multiple Linux/390 images, Dave Jones recommended taking a look at a product by Aduva:
"Their product maintains a database of what RPM packages, at what VRM level, are installed on each server in a server farm. Then when an RPM package is updated, the product automatically installs and configures the new patch on each server that needs it, and restarts the server. If other installed packages on a server need to be updated as well, Aduva handles that as well.
"There's a rumor that they are porting this application over to z/VM to support large Linux virtual server farms."

Other people recommended using packages such as rsync, rdist, etc, but Bill Barr recommended using expect/autoexpect to automate certain parts of the task. To use expect, you'll also need Tcl installed.
Jay van der Meer said "We are using ant and the ftp task. It uses a XML control file to handle the processing. It can handle different user id's, and other options per FTP site."

03/26/2002 - Gordon Wolfe posted a follow up to a problem he reported previously where he couldn't get Konqueror on SLES7 to work with his company's proxy firewall. It turns out that ECN was enabled by default in the TCP/IP stack, and some internal routers were having problems with it. Gordon's network person recommended issuing a

echo "0" > /proc/sys/net/ipv4/tcp_ecn

03/27/2002 - In response to a question/complaint about DF/HSM not recognizing the Linux/390 DASD format, Volker Sameske of IBM pointed out two HOWTOs that would be of interest to OS/390-z/OS shops that are using the Linux/390 cdl (compatible disk layout) format. The two HOWTOs are for storage administrators to use DFSMShsm and DFSMSdss to backup and restore Linux/390 partitions and volumes. Pointers to these two IBM HOWTOs have been added to the HOWTO page on this site.

03/27/2002 - There was some discussion on the mailing list about the hostid command, and just exactly what the value was that was being returned, and where it came from. Dougie Lawson finally posted a note that showed it was the little endian representation of the system's IP address. For example, his system with IP address 9.180.130.22 shows a hostid of B4091682, B4=180, 09=9, 16=22, 82=130. This can be complicated by whether a particular hostid displays the results in base 10, or base 16.

03/27/2002 - Mark Post reported an article about Ximian Connector. According to the article "Ximian Connector, a client-based product, serves as an extension to the company's Evolution suite of groupware products that enables Linux and Unix users to better manage personal information as well as to collaborate with Windows®-based colleagues using Exchange 2000."
Mark closed out with the comment "So, now we have the Bynari Insight server for shops that want to keep their Outlook clients but replace the Exchange servers, and we have the Ximian connector for people that want to keep their Exchange servers, but have a need for Linux desktop users to be able to connect. Or, you could replace the Exchange servers, and let your users decide which desktop they want, Windows® or Linux, and still be able to communicate effectively."

03/28/2002 - Mark Post reported that SAP had released its database code and development environment under the GPL some time ago. He downloaded them (about 13MB and 3MB, respectively) to see if they would build, but discovered that the development environment had some Intel binaries in it that were needed to do the build. An inquiry to the SAP team that supports the open source product said that the source to the development environment itself should be available in a few weeks.
