SLES9 Install with FTP under VM question

MySQL - glibc 2.2 - glibc 2.3 question
Got a question. We're currently running SLES8 SP3 with glibc 2.2.5. I was APPLY CHECKing, er, running rpm -Uh --test on mysql-4.0.18 and mysql-client. Several dependencies were indicated, including libc.so.6 (GLIBC_2.3) needed for mysql-4.0.18. I then did a rpm -Uh --test on glibc-2.3.3-98. I received an error:failed dependencies with a list of products (like rpm, susewm, kdebase3, webalizer) that needed libdb.so.2 (GLIBC_2.0). So, actually, a few questions. What is the approriate thing to do here? Install glibc 2.3.3 and then re-install the products called out for libdb.so.2 and other GLIBC_2.0 dependencies? Install glibc 2.3.3 and install higher versions of the products called out for libdb.so.2? Is it better just to do a forced march to SLES9? Finally, is there a doc or HOWTO that talks about the sort of dependencies and issues between glibc versions and products that use them?

Re: MySQL - glibc 2.2 - glibc 2.3 question
snip It looks as though you're trying to install RPMs from SLES9 on a SLES8 system. Don't do that. If you need packages that are at the version levels in SLES9, then upgrade to SLES9. Trying to do otherwise will eventually result in just about the same thing, but with a whole lot more time spent (wasted), and greatly increased stress levels. /snip Yes, the RPMs came from SLES9. I see what I'm doing wrong. The RPMs were built for SLES9 (and with glibc 2.3) which is of course different from SLES8 (with glibc 2.2). Thanks, Mark.

Can multiple ethx be defined on one OSA-E port
Got a question: Can two network interface be defined with different IP addresses in a Linux instance (in this case an lpar, SLES 8) with both interfaces using devices numbers associated with the same OSA-E port? For example, assuming -000f are defined for a particular OSA-E port, can two interfaces be done: noauto;qeth1,0x,0x0001,0x0002;addparms,0x10,0x,0x0002 noauto;qeth2,0x0008,0x0009,0x000a;addparms,0x10,0x0008,0x000a And then associate two different IP addesses (say 192.10.20.01 and 192.30.10.10) with the two different interfaces, one to eth1 and one to eth2? Or, is there a more appropiate way to use two IP addresses when there is only one physical (OSA-E) port?

/snip on Yes, you can do it the way you asked. I guess the real question is: what are you trying to accomplish? The answer to that may be radically different from what you're trying to do. /snip off Thanks, Mark. Fair question. The OSA-E card has one port connected to a switch to the intranet and a given IP address is assocated with the network interface. A group of users would like to access the lpar but with an IP address that reflects their subnet. So I thought one way be be to define another eth_ and associate their IP address scheme with it.

LVM usage between lpars
Folks, Sanity check. I've defined two LVM physical volume groups. I plan to share these two volume groups between three lpars running Linux (SLES 8).

Question about method of backing up Linux/390 system to VTS
Folks, I have a SuSE Linux 2.4.19 system running on an lpar. I was planning on using Tivoli Storage Manager client for file-level backup to our NT-based TSM server (which would then send the data to the open-system side of our IBM VTS). [TSM is the standard mechanism for our proprietary 'open-system' backups.] But the lpar also has access to the s/390 side of the VTS. Have others used programs like dar or amanda to provide the same capability (file-level backing up to the VTS) without the network overhead (shipping the data out over the network). If so, and the s/390 side of the VTS is shared with other OS/390 lpars, can I rely on the VTS to manage the tapes (whether their scratch or not, ala TMS) or is there other software I need or would this run a foul with TMS on the OS/390 lpars?

rpm under chroot to 'apply' maintenance

I was wondering what exactly one can do in a native LPAR installation of Linux, using the 2.2x kernal (I've not gotten the 2.4 distribution) from SuSE to backup their system. With 2.2 native, you have limited options. You can attach a tape drive to the LPAR and use dump manually, or you can use Amanda, which is on your SuSE CDs. Amanda is by far the more attractive of the two options, and it supports connnecting over the network to another system and dumping to a remote tape drive. You can also use Tivoli Storage Manager if you have it, but the L/390 client seems rather unreliable at the previous release level -- I haven't tried the most current one yet, as they don't seem too interested in most of the 390 versions of TSM at the moment, and it's not cheap. CA has a product as well, but it's not cheap either. I understand that the 2.4 kernal allows/can allow the s/390 side of the coin to backup the Linux volumes natively? Is that the best way to go? (The 2.4 kernal/distribution) This is in general a good idea but it still allows only full-volume or full-partition dumps, which are great for DR, but not so hot for A.

Amanda is probably the best bet here as well, along with using DFDSS to do full volume dumps periodically with the Linux system down for consistency sake. -- db
Re: DASD Management Question
For quick and simple full volume dumps (so you have as least some sort of backup), I use the OFFLINDR utility from ftp.ox.ac.uk/pub/linux/s390/offlindr or maybe its www.clueful.co.uk/mbeattie/s390/offlindr.jcl now. Might want to check into Innovation's Upstream. Upstream is a great product and I'm pretty sure they have a Linux agent now. Dave No warrantee is implied or explicitly stated.

We've gotten our first instance of linux up in a LPAR with miminal issues. However we would like to back it up. IBM's DFHSM does not recognize the DASD format. Veritas has unoffically stated that they don't support a Mainframe Based facility. This pretty well leaves only IBM's Tivoli Dasd Management system. What about SILO's, we have STC's for mid-range and mainframe use. What about Tape Manangement Systems? Whats keeping track of, where? Comments, recommendations, and references are appricated! Thanks Gerald Benton
Re: New copyright bill could mean the death of Linux...
One would almost get the impression that the trial lawyers and congresspeople are just trying to export as many jobs and as much creativity as possible to other countries.

I look forward to the outlawing of Xerox machines - and indeed ballpoint pens (any hardware that can reproduce copyrighted material). This is of course an unintended consequence of the 1st amendment's creation of a market in congresscritters (they ought to trade the _ss*^%s on Wall St), and yet another illustration of lawmakers' propensity for solving all problems with yet further laws (if the only tool you have is a hammer, every problem looks like a nail).

No software from outside the US could be legally imported, since it wouldn't include the copy protection. It would also end the shared libraries, since I couldn't write a piece of software and give it to anyone else without violating the law and facing criminal charges. Robert P.

Resource and object access authorization products
Folks, We are presently evaluating a package called CA eTrust Access Control, which provides C2 and some B1 like security controls for resource and object access authorization. While we have been exploring SELinux, we ware looking for something that provides centralized security for applications hosted on Linux. Anyone know of any other products we should consider?

SE-Linux w/ Linux for S/390
Curious if anyone has tried to apply the NSA's SE-Linux patches to their Linux for S/390 or zSeries distribution. If you have, how did it go? What distribution and kernel level did you use? Did it impact you administration of the Linux system? Thanks Dave No warrantee is implied or explicitly stated. Do not bend, fold, spindle, or mutilate.
