[opensuse] boot32.efi for 64 bits processor and Leap
by jdd 16 Aug '24

16 Aug '24

Hello, We see more and more often very small but powerfull computers, atom multicore 64 bits, but with UEFI 32 bits firmware. I have one now ("It Works TW891" paid 129€ - 32Gb ssd + 2Gb ram, runs almost perfectly windows 10 32bits or Debian 64bits). these computers can be installed with 64 bits distros, but they need absolutely a 32 bits loader. Right now I on ly know of the hybrid debian 32/64bits dvd to be able to install. Notice that *only the loader* have to be 32bits, the generic name being boot32.efi copying a generic loader to the Leap EFI folder allows booting, and probably installing (I couldn't make all the tests), but the generic one gives only a grub prompt, not handy. Could it be possible to add to the Leap isos this 32 bits loader? only this one have to be 32bits, AFAIK nothing else have to be changed. thanks jdd -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] How to make sure that each vNIC in guest is always associated with a correct VLAN?
by Martin T 14 Aug '24

14 Aug '24

Hi, I have six virtual bridges in xen host machine and following virtual machine configuration file section defining the vifs: vif = [ 'bridge=br10', 'bridge=br20', 'bridge=br30', 'bridge=br40', 'bridge=br50', 'bridge=br60' ] This means that in the guest(openSUSE Leap 42.1) I have six vNICs(eth0 - eth5). Can I be sure that eth0 is always connected to br10, eth1 to br20, etc? Or should I specify a MAC address for each vNIC created like this: vif = [ 'bridge=br10, mac=00:14:5E:11:C6:F1', 'bridge=br20, mac=00:14:5E:11:C6:F2', 'bridge=br30, mac=00:14:5E:11:C6:F3', 'bridge=br40, mac=00:14:5E:11:C6:F4', 'bridge=br50, mac=00:14:5E:11:C6:F5', 'bridge=br60, mac=00:14:5E:11:C6:F6' ] .. and then configure udev rules which make sure that interface associated with MAC 00:14:5E:11:C6:F1 and br10 is always named eth0, interface associated with MAC 00:14:5E:11:C6:F2 and br20 is always named eth1, etc? Or maybe there is a better way using /etc/sysconfig/network/ifcfg-* files? thanks, Martin -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Bad blocks on a ReiserFS volume. How to retrieve files?
by Silviu Marin-Caea 14 Aug '24

14 Aug '24

I have a large hard-disk (120 GB) on which some blocks went bad. Now, it cannot be mounted. Attached is what debugreiserfs says. What can I do; I'm newbie to reiserfs architecture. I thought that ReiserFS keeps copies of the superblock or something, like ext2/3 does. reiserfsck says "error occured looks like hardware problem. bread cannot read block 13271040". That's the actual number it displays. PS I have asked the same question on the reiserfs-list, but it's extremely low traffic. Maybe someone here knows more. Thank you Filesystem state: consistency is not checked after last mounting Reiserfs super block in block 16 on 0x1642 of format 3.6 with standard journal Count of blocks on the device: 29945160 Number of bitmaps: 914 Blocksize: 4096 Free blocks (count of blocks - used [journal, bitmaps, data, reserved] blocks): 29154954 Root block: 14969 Filesystem is NOT clean Tree height: 4 Hash function used to sort names: "r5" Objectid map size 10, max 972 Journal parameters: Device [0x0] Magic [0x34ae2c74] Size 8193 blocks (including 1 for journal header) (first block 18) Max transaction length 1024 blocks Max batch size 900 blocks Max commit age 30 Blocks reserved by journal: 0 Fs state field: 0x0 sb_version: 2 inode generation number: 35482 UUID: 48d29ced-fe37-4c68-adf8-32ace9f2be45 LABEL: Set flags in SB: ATTRIBUTES CLEAN

[opensuse] Project management software question for project managers
by Ted Byers 29 May '24

29 May '24

I am looking for project management software I can install on my Suse box. Alas, there are quite a number of prducts that claim to be suitable project management products, but I am hoping to obtain a little help separating the wheat from the chaffe. Basically, when I open the project management software, I want to be able to choose from among a number of projects that are under way, and then see the relation between a client's wish list and the functional requirements specs, and then how these specs relate to the UML diagrams that have been created, and from there, what tasks have been defined for each requirement and the identity of all persons involved, the developers and their managers, and the person who designed the code that supports the requirement. And with that, I want to be able to see the project's timeline, the related bugs, &c. I would even want to be able to open the source code files and examine the code that was actually written. Here is my wish list: 1) a web application that stores data in either PostgreSQL or MySQL. 2) easy integration with UML tool (or has it's own UML tool that supports round trip engineering) 3) resource management (e.g. computers, and development tools, that can be used, personelle assigned to each task) 4) documentation of relation between functional requirements specs to specific tasks and specific unit and integration tests. 5) time/effort tracking 6) bug tracking, including data relating the existance of the bug, and effort required to fix it, to the person who wrote the original code, the person who supervised him or her, and the person who designed the 'feature' in question, the time taken to complete the original task, and the technologies used (to imprrove accountability as well as to determine retraining and continuing education needs (people aren't disposable, so instead of taking a harsh aproach to problems identified, I prefer to use education as a corrective, but I can't design corrective instruction without knowing precisely what the need is). I also need to know if a developer has a higher than normal bug rate simply because he doesn't take enough time to ensure the job is done right, or because I haven't adequately trained him, or because of a poor choice of tools, or somethng else that may be my fault. 7) use of task effort tracking history to generate provisional effort/cost estimates from new project's functional requirements 8) easy integration with open source ERP products like OFBiz (which may make trakcing resources and manpower easier, as well as connect real production data to the enterprise's accounting systems) 9) easy integration with CMS products, like Wordpress (especally for production documentation, includng degin documentation and user guides and reference manuals) 10) easy integration with verion control systems such as subversion. If there is a decent product that supports all of this, great (and language used to implement it doesn't matter), but if I have to write code to add missing requirements, then I am limited to those implemented using Perl or Java (and running on Tomcat). I don't know PHP well enough, and I don't know Ruby at all; and I really don't want to think about implementing this sort of thing in C++ (though I could if absolutely necessary). If you have project management experience, and use tools that are available for Suse Linux, what software product(s) did you use, and with what result? While I await relies, I will continue to review web documentation for those products I have found so far, to see if any of them are a) suitable for use in production and b) to see to what extent they support the features I am after. I have seen a number of products so far in my search, that deserve to be nameless, because they provide no way to relate cost estimates to one's team's track record, or to the details of the design, and seem satisfied with production of a pretty gantt chart (which is why I have formed the view that there is a whole lots of chaffe in the set of applications that call themselves project menement software - I have yet to find anything that really has the potential of being labelled wheat).

Sorry SuSE: 9.1 is Waste of time and money!
by Terje J. Hanssen 17 May '24

17 May '24

I am sorry to conclude that my upgrade from SuSE 9.0 Pro to 9.1 Pro has been waste of time and money for me, so far. The same I have to say about the free SuSE "Installation support". The reason is that my SuSE 9.1 installation only detects 1 of my 3 SCSCI devices (as I wrote in another subject on this forum: http://lists.suse.com/archive/suse-linux-e/2004-May/3254.html) Yamaha 4416S CDRW recorder detected HP DVD Writer 100i NOT detected Epson 1640SU scanner NOT detected It's rather stupid. I have installed 9.1 using the DVD disk just in the HP DVD drive, but after the installation of 9.1, the KDE/Konqueror /media/recorder cannot access it and YaST2 cannot install additional software from it. Only one "Cdrecorder" is found in My computer and that is the Yamaha 4416 drive, which the KDE/Konqueror file manager assign as /media/recorder11. I am sure 9.1 is the reason, as I hadn't this problems with 9.0. I have tried both an update and two several new installation of 9.1. Neither SJDS nor Windows on the same multiboot PC have problems to detect these devices. In my opinion SuSE should therefore debug 9.1 better and longer, and not leave the problems to the customers. I see SuSE notes on their web saying that they know SCSI scanners are not detected in 9.1. But regarding my HP DVD writer problem, the SuSE support (as usual) don't take the responsibility and argue that this problem (a combination of IDE disk and SCSI devices) isn't included in their free installation support! This sounds remarkable, and I have never had a modern PC of so simple model or configuration that it has fitted the limited rules for the free installation support. Terje J. Hanssen

by yh＠ottawa.com 03 Apr '24

03 Apr '24

Yesterday, I finally got sound going on my Linux setup. I downloaded RealPlayer G2 and it worked beautifully. Today, RealPlayer run but no sound coming out. All other sound functions still work. I can still play my CD, have system sound BUT no sound when I run RealPlayer. /var/log/message said kernel: Sound: DMA (output) timed out - IRQ/DRQ config error? but KDE sound still work. I have re-installed RealPlayer 3 times now, still no sound when I run the RealPlayer. Any help is appreciated.

[opensuse] Kernel compilation the openSUSE way?
by Bjoern Voigt 28 Nov '21

28 Nov '21

I usually take the newest openSUSE kernel (from repository Kernel_stable). But since some month I have a DVB T2 HD card, which requires a patch (see https://bugzilla.kernel.org/show_bug.cgi?id=194171) So I need to compile kernels myself. I have a working compilation path. But the current path has 12 steps! It takes some time. I wonder, why it is so complicated to configure, compile and install a Kernel under openSUSE. Is there a better/easier/automated way to configure, compile and install a Kernel under openSUSE? I know this blog article. But the article uses Vanilla kernels and also needs 6 steps. With additional patches (4 steps), third-party modules (2 steps) and cleanup (1 step) the article would also need 13 steps: Compiling the Linux Kernel, the SUSE way https://www.suse.com/communities/blog/compiling-de-linux-kernel-suse-way/ This is my Kernel configuration, compilation and installation path: 1. Update kernel-source and kernel-default from Kernel_stable repository 2. Save kernel-source: cp -a /usr/src/linux-4.x.y-... /usr/src/linux-4.x.y-my 3. Apply my patches cd /usr/src/linux-4.x.y-my patch -b -p1 < ~myuser/.../my-kernel-patch.patch 4. Copy standard configuration: cd /usr/src/linux-4.x.y-my cp -v /boot/config-4.11.4-1.gcba98ee-default .config 5. Edit .config: remove CONFIG_LOCALVERSION, CONFIG_DEBUG_KERNEL, CONFIG_EXPERT remove some hardware-dependent settings 6. edit configuration interactively: Disable CONFIG_EXPERT and CONFIG_DEBUG_KERNEL, because otherwise "make binrpm-pkg" creates huge kernel binaries. make oldconfig [...] Local version - append to kernel release (LOCALVERSION) [] (NEW) -my1 * * Configure standard kernel features (expert users) * Configure standard kernel features (expert users) (EXPERT) [N/y/?] (NEW) Kernel debugging (DEBUG_KERNEL) [N/y/?] (NEW) make menuconfig Do some additional configuration. 7. Compile kernel (-j4 for four processor cores, ionice and nice to reduce the load, binrpm-pkg for RPM without source-RPM) make clean nice ionice -c idle make -j4 binrpm-pkg 8. Install the kernel RPM package rpm -Uvh /usr/src/packages/RPMS/x86_64/kernel-4.x.y_my1-....x86_64.rpm 9. Install necessary symbolic links for "dkms" cd /lib/modules/4.x.y-my1 ln -sv /usr/src/linux-4.x.y-my source ln -sv /usr/src/linux-4.x.y-my build 10. Update third-party modules (e.g. Nvidia driver): dkms install -m nvidia -v 375.66 -k 4.x.y-my1 11. Cleanup cd /usr/src/linux-4.x.y-my make clean 12. Select Grub configuration and reboot grub2-once --list | less grub2-once 2 reboot Greetings, Björn -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
