[opensuse] openSUSE Windows AD client and Group Policies
by Roger Oberholtzer 03 Jun '15

03 Jun '15

In the office, our openSUSE machines join the Windows Active Directory. This works great and allows one to log in using the AD credentials. Not that we use that. But it works great. My question here is how much more we could use from the AD in Linux. I know that if SAMBA is a domain controller, it can serve group policy files to clients. But is there anything SAMBA as a client can do with Group Policies? I am thinking things like mapping shared drive or printers. I only seem to see (or recognize) this discussion in the context of a SAMBA controller, not as a client. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] vfat timestamp again
by Istvan Gabor 02 Jun '15

02 Jun '15

Hello: I took photos with a digital camera which saves the photos to a vfat formatted sdcard. The camera's clock is set correctly according to my local time. When I mount the vfat filesystem in openSUSE 13.2 using a card reader, the timestamps the photos are 2 hours ahead. (OpenSUSE 13.2 system time is set to UTC.) Eg. timestamp shows 18:20 instead of 16:20, the time when the photo was actually taken. I find this behavior - again - unacceptable, ridiculous, and annoying. Isn't there any option with which this stupid behavior could be changed so that the filesystem times would be interpreted as the user's local time? Is this so big expectation? I would like to archive the images, and therefore the timestamps applied at mounting will be preserved. I don't want to archive wrong timestamps, because it is important when the photos were taken. I know I can look at metainfo, but it is not real a solution. What I want is changing the timestamps applied when the filesystem is mounted. Thanks, Istvan -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Secondly when you remap sectors, it slows down the drive -- so that drive won't be within 'tolerance' for hardware RAID, so you'd need to replace the drive most likely (if you had a hot spare in the machine, it could immediately start a rebuild). Third -- RAID1 is safer than RAID6 for the same # of total disks in all cases w/same # of even spindles (need an even number for RAID1, obviously). If you only have 3 disks total, you could probably do RAID6 and it would be safer, but 1 data + 2 parity...ouch. But the 1st minimum size demonstrates the problem (and it gets worse w/more disks). With min number of spindles that will work for both: 4, RAID6 would have 2 data disks and 2 parity. while raid10 would have 2 data disks and 2 mirrors. If your failure rate is 'x', then the no-fail rate is 1-x per disk. In the raid 6, if any of the other 3 disks fail (in addition to 1st failure), the raid is toast. With a RAID10, there is only 1 disk that can cause the whole array to fail (the mirror of the one that went bad). If you get a 2nd fail on another pair, you can still rebuild. With only 1 disk "exposed" on RAID10, the % chance of the whole RAID failing is the %chance of 1 disk failing. However, w/raid6, there are 3 disks that are critical to rebuild the bad one -- their "no fail case is (1 - x)**3. I.e. say it was a 1% fail, 99% nofail. In RAID10 chances of whole RAID being safe would be 99% (the no fail rate for the 1 partner of the one that failed). In RAID 6, though it's .99**3 -- or .970. In that best case RAID6 has 3x the 'total fail' chances as the RAID10's. If you have 8 total spindles (6 data/2parity for raid6 vs. 4data+4mirror for raid10), then 1 disk goes. For RAID10, the total fail case only happens if the failed-drive's pair go's so it's still 99% chance of not failing. Vs. RAID6, .99**7 == .932) -- or a almost a 7% chance of a total fail vs. RAID10's 1% chance. The next point up is moving from 512-byte sect disks to 4k... It takes less space for a more power ECC on 4k than the one on 512: (from a Hitachi brief:) .... The second benefit is that a larger and more powerful error correction code (ECC) can be utilized, providing better integrity of user data.... > Only if you are using media scrubbing routinely can you have confidence > that the member drives go from "perfect" to failed without a silently > degraded state in the middle. --- LSI defaults them to once/week. > > When TB size drives first hit the market, a lot of raid5 rebuilds were > failing due to the silent bad sector degradation.

With RAID10, it's a constant. (Combinatorics) -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] html5 player of youtube says "An error has occured" on chromium
by Weiwu Zhang 02 Jun '15

02 Jun '15

Videos play fine on Firefox using HTML5 player of youtube.com, but the same videos give "an error has occured" on my chromium 43.0.2357.65-29.1. System is OpenSUSE 13.2, 64bit x86. Not a single video on chromium plays, e.g. youtube.com, lynda.com, presto.com.au, netflix.com.... There are no technical information besides the for-mago message "An error has occured". Strange enough, youtube.com/html5 on chromium says I have everything supported, 6 tickes all ticked. While youtube.com/html5 on Firefox says I have only 2 tickes of the 6 ticked: "HTML Video Element", and "WebM", Yet, Firefox perform okay when chromium can't. Why? If I do a google search, most people suggest that I should switch to HTML5 player instead of Adobe Flash (was done already), install gstreamer-0_10-plugins-ffmpeg and gstreamer-0_10-fluendo-mp3 (was done already, although don't think this suggestion is relevant, since youtube moved away from h.264 and mp3 codecs long ago), or check youtube.com/html5 (checked) Thanks! -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] libKF5WindowSystem5 devel package?
by blue hut 02 Jun '15

02 Jun '15

I would like to code on the LXQt project. So I checked out their code and walked my way through the cmake. Currently I am trying to compile lxqt-config. Running cmake and seeing what libs I need to install, so far I installed: libqt5widgets-devel libQt5DBus-devel libQt5xml-devel libQt5concurrent-devel libqt5-qtx11extras-devel libqt5-linguist-devel liblxqt-devel Now cmake is asking for FindKF5WindowSystem, exact message: CMake Error at /usr/share/cmake/lxqt/lxqt_use.cmake:62 (find_package): By not providing "FindKF5WindowSystem.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "KF5WindowSystem", but CMake did not find one. Could not find a package configuration file provided by "KF5WindowSystem" with any of the following names: KF5WindowSystemConfig.cmake kf5windowsystem-config.cmake zypper told me libKF5WindowSystem5 is already installed and i dont see a libKF5WindowSystem5-devel package for this one, no idea why. Why is there not devel package for this? Am I missing something here? :-) -- Michael -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] network manager only connects after 2nd or 3rd attempt
by Daniel Bauer 02 Jun '15

02 Jun '15

Hello, on my laptop with OS 13.2, after booting the network manager shows that it is connected to my wifi, but there is no connection to the internet, i can't even get to the router (192.168...) Then I click on disconnect and then on connect again and it usually works. Sometimes I need a third or a fourth attempt. It looks to me that if "connecting" takes a longer time, then the connection does not work, although shown as connected, and when it goes fast, it works... It does not depend on the distance to the antenna. What could be the reason for this? Where can I search and for what should I look? thanks for hints Daniel -- Daniel Bauer photographer Basel Barcelona http://www.daniel-bauer.com room in Barcelona: https://www.airbnb.es/rooms/2416137 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] SD card error
by jdd 01 Jun '15

01 Jun '15

Hello, I use quite often SD card for video recording. I have problems with card flow rate measuring, because video is sometime very demanding, so I try to verify the card before use. however, cards are chepaer nowadays, but the quality is variable. problem is that some tools works and give data, others do not work, and specialy rsync!! normally rsync gives at the end of the work a summary with the flow rte (often refered as "speed") the target file system is fAT32 (no choice) the card si test here failed on real record in a 5DMKIII, probably because the flow rate of the device (around 32Mb/s) was too high. but look at these results: http://susepaste.org/27536079 rsync gives an error after some time, but f3write do not and I have similar results for some days, now, sometimes error, sometimes not NB: f3write is a specialized tool to verufy SD cards, similar to the windows tool h2testw any idea? thanks jdd -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
