playing DVDs on C7
by Fred Smith 20 Dec '15

20 Dec '15

Hi all! I'm trying to finish setting up my newly upgraded C7 system. It's on the same hardware I ran C6 on for several years. on C6 I had no trouble playing DVDs (after installing tons of packages and libdvdcss). Well, on C7, I've got totem (videos) and all its plugins I can find via yum, VLC (from nux) all the gstreamer and gstreamer1 packages I can find, everything with "dvd" in its name, including libdvdcss from nux. vlc will kinda play movies, i.e., moving garbage appears on the screen, sometimes it'll resemble something from the movie, but most of the time not so much. I can't figure out what's missing here. Totem played a movie for me this afternoon, flawlessly, but now I can't get it to do anything. sometimes it starts up as a plain gray box with no borders, no controls, no nothing, and has to be killed. sometimes it draws the player controls but never starts playing. I've got two DVD drives, one of them replaces a broken one, but the other one has been there for 2-3 years. I've been googling for hours, but haven't turned up anything that I haven't already tried. I'd appreciate suggestions. thanks in advance! here's some yum listings of things I have installed: yum list installed | grep -y dvd dvd+rw-tools.x86_64 7.1-15.el7 @anaconda libdvdcss.x86_64 1.2.13-1.el7.nux @nux-dextop libdvdnav.x86_64 4.2.0-8.el7 @anaconda libdvdread.x86_64 4.2.0-6.el7 @anaconda radvd.x86_64 1.9.2-9.el7 @base yum list installed | grep -y vlc vlc.x86_64 2.2.1-6.el7.nux @nux-dextop vlc-core.x86_64 2.2.1-6.el7.nux @nux-dextop vlc-extras.x86_64 2.2.1-6.el7.nux @nux-dextop yum list installed | grep -y totem totem.x86_64 1:3.14.3-5.el7 @cr totem-nautilus.x86_64 1:3.14.3-5.el7 @cr totem-pl-parser.x86_64 3.10.5-1.el7 @cr yum list installed | grep -y gstreamer PackageKit-gstreamer-plugin.x86_64 1.0.7-5.el7.centos @cr gstreamer.x86_64 0.10.36-7.el7 @anaconda gstreamer-ffmpeg.x86_64 0.10.13-15.el7.nux @nux-dextop gstreamer-plugin-crystalhd.x86_64 3.10.0-11.el7 @epel gstreamer-plugins-bad.x86_64 0.10.23-5.el7.nux @nux-dextop gstreamer-plugins-bad-free.x86_64 0.10.23-20.el7 @anaconda gstreamer-plugins-bad-nonfree.x86_64 0.10.23-2.el7.nux @nux-dextop gstreamer-plugins-base.x86_64 0.10.36-10.el7 @anaconda gstreamer-plugins-good.x86_64 0.10.31-11.el7 @anaconda gstreamer-plugins-ugly.x86_64 0.10.19-17.el7.nux @nux-dextop gstreamer-tools.x86_64 0.10.36-7.el7 @anaconda gstreamer1.x86_64 1.4.5-1.el7 @cr gstreamer1-libav.x86_64 1.0.6-1.el7.nux @nux-dextop gstreamer1-plugins-bad-free.x86_64 1.4.5-3.el7 @cr gstreamer1-plugins-bad-freeworld.x86_64 gstreamer1-plugins-base.x86_64 1.4.5-2.el7 @cr gstreamer1-plugins-good.x86_64 1.4.5-2.el7 @cr gstreamer1-plugins-ugly.x86_64 1.0.6-2.el7.nux @nux-dextop -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. ------------------------------- Romans 5:8 (niv) ------------------------------

Serial Communication
by Chris Olson 19 Dec '15

19 Dec '15

Many years ago, we began scrapping the RTOS approach for some of our timing-critical applications. Our first applications were based on Solaris real-time extensions and served well us well for many years. Then came the era of shaky support for Intel Solaris and we moved many applications to Linux. There appeared to be no actual need for special real-time features with a good Linux distribution kernel and a GHz processors. One of our most productive applications involves special test equipment computers that drive high speed serial ports. The original development of these systems had the "added benefit" of helping us to learn udev rules. The serial communication is very flexible and most of it is script driven. A current need to update computing platforms is driving script review. There appears to be a bit of variety in outputs to the serial drivers. The echo of a string with redirection to the serial driver, cat of a file with redirection to the serial driver and dd of=/dev/.... are methods used at various places in the scripts. It is not at all clear what drove the choice of the output method at various points in the application. In addition, changing the method of output has not succeeded in breaking most of the applications. Is there some fundamental difference between these methods of output to the driver that might trip us up as we simplify the scripts and port to new computer platforms? Thanks in advance for any assistance.

Today's Topics: 1. Release for CentOS AltArch 7 (1511) on x86_64 (Karanbir Singh) ---------------------------------------------------------------------- Message: 1 Date: Sat, 19 Dec 2015 00:47:23 +0000 From: Karanbir Singh <kbsingh(a)centos.org> To: CentOS Announcements List <centos-announce(a)centos.org> Subject: [CentOS-announce] Release for CentOS AltArch 7 (1511) on x86_64 Message-ID: <5674A91B.40508(a)centos.org> Content-Type: text/plain; charset=utf-8 I would like to announce the general availability of the following CentOS AltArch 7 Releases: * CentOS AltArch 7 (1511) for i686 * CentOS AltArch UserLand 7 (1511) for Armhfp * CentOS AltArch 7 (1511) for PowerPC64 (TechPreview) * CentOS AltArch 7 (1511) for PowerPC8 LE (TechPreview) We anticipate CentOS AltArch 7 (1511) for Aarch64 will be ready for release within the coming days, and will be announced independently. The CentOS AltArch SIG is a group of people working to build alternative architecture support derived from CentOS Linux's sources. You can find more details about the AltArch group at https://wiki.centos.org/SpecialInterestGroup/AltArch including details on how to get involved and ways to get help for architecture specific issues. Releases under the AltArch SIG are hosted at http://mirror.centos.org/altarch/ and available from external mirrors via rsync, http, ftp as usual, however under the /altarch/ path. Yum configs shipped in the altarch builds points at mirror.centos.org instead of mirrorlist or the external mirrors, as we are still working through the mechanics to facilitate the wider mirrorlist process. We hope to have this in place within the next 2 months, and updates to the yum configs will be issued, when ready, via an updated centos-release rpm. We are hosting a CentOS Dojo in Brussels, Belgium on the 29th Jan 2016. Lots of the key people working on the AltArch builds will be present there and it would be a great forum to engage with these groups. You can get the details for the event at https://wiki.centos.org/Events/Dojo/Brussels2016 including the registration links. In order to bootstrap these builds, we have turned on direct downloads of this content from mirror.centos.org. We do encourage people with the capacity to help seed with external mirrors. Details on howto run a CentOS Mirror are available at https://wiki.centos.org/HowTos/CreatePublicMirrors A key part of our AltArch plans is to make resources available to all the other SIG's in the CentOS environment, so they are able to build, test, deliver their content for these architectures. We are working on setting things up, and hope to start rolling out altarch support for https://cbs.centos.org/ in the first quarter of 2016. If you are engaged in any of the SIGs and would like to find out more details, please come along to our buildsystems meeting that takes place on Mondays in #centos-devel on irc.freenode.net. Details on this meeting and the other SIG meetings can be found in our community meetings calendar published at https://www.centos.org/community/calendar/ . Bug reports and feedback about specific packages should be filed at https://bugs.centos.org/ against the relevant package name, for project CentOS Linux 7, in the same manner as you would for x86_64. However, do mention the architecture as applicable. -------- CentOS AltArch 7 (1511) for i686 : This architecture build supports 32-bit Intel/AMD x86 machines and 32 bit IOT x86 boards.

SIG Notes: https://wiki.centos.org/SpecialInterestGroup/AltArch/Arm32 The armhfp build is delivered as a userland build, implying that kernel and bootloader delivered is not derived from the CentOS Linux 7 distro, but comes from either an upstream kernel.org mainline kernel or is a vendor supported kernel for their own hardware piece. As such, the Armhfp build does not aim to deliver a complete feature set, and is labelled as a UserLand release. There are also no installer images delivered for this architecture. The images shipped are ready to run and are board specific. While there is plenty of desktop and X related support available, our focus for these builds has been towards the server and IoT roles. We have a dedicated mailing list for the ARM ports ( both Armhfp and Aarch64 ) at https://lists.centos.org/mailman/listinfo/arm-dev ; questions specific to these builds and images should be posted there. * CentOS-Userland-7-armv7hl-Minimal-1511-BananaPi.img.xz sha256sum : d461144b471434a275268e85828def38c09e265da24b71d2f10771d264532368 direct link : http://mirror.centos.org/altarch/7/isos/armhfp/CentOS-Userland-7-armv7hl-Mi… * CentOS-Userland-7-armv7hl-Minimal-1511-CubieTruck.img.xz sha256sum : 17c3944429ac323c636ee955062d8177219f397fea4416dca87ca19092b646ec direct link : http://mirror.centos.org/altarch/7/isos/armhfp/CentOS-Userland-7-armv7hl-Mi… *CentOS-Userland-7-armv7hl-Minimal-1511-RaspberryPi2.img.xz sha256sum : 05e8c58cd837b90c0ab423b3730ee20ad185e19f346f531d3717c51358ea72cf direct link : http://mirror.centos.org/altarch/7/isos/armhfp/CentOS-Userland-7-armv7hl-Mi… -------- CentOS AltArch 7 (1511) for PowerPC64 (TechPreview) : This architecture is for 64-bit IBM POWER7 machines using big endian byte ordering.

CentOS 7.2 - Fast TSC calibration failed.
by Earl A Ramirez 19 Dec '15

19 Dec '15

Dear All, I have downloaded CentOS 7.2.1511 DVD and tried to install it on a new laptop that comes with an Intel i7 6th generation processor and don't matter which option I use (install, test media or troubleshooting); I get the following error: [ 0.000000] tsc: Fast TSC calibration failed [ 0.321345] pnp 00:0d: can't evaluate _CRS: 1 At this time I am not able to use any keys on the keyboard; therefore, the only option I have is to power the laptop off. The laptop specifications are as follow: Processor : Intel Core i7-6700HQ 2.6GHz (Turbo up to 3.5GHz) Skylake RAM : 32 GB DDR4-SDRAM Graphics Coprocessor : NVIDIA GTX960M 2GB GDDR5 Chipset Brand : Intel I waited for CentOS 7.2 because I saw that upstream had [0] "the 'intel_idle' and 'pstate' driver updated to support 6th Generation Intel Core processor". Shall I file a bug for this or will I need to create a ISO with an customised kernel or use one of ElRepo's 'lt' or 'ml' kernels which will include support for the new hardware. The full specification of the laptop can be found here [1] [0] https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/ht… [1] http://store.asus.com/us/item/201510AM170008064/A17602 -- Kind Regards Earl Ramirez

CentOS 7 installer bug?
by m.roth＠5-cent.us 19 Dec '15

19 Dec '15

The other admin I work with seems to have found a bug in the installer. The setup is: two internal SSD drives. Once the GUI gets to "select drive to install on", he goes to <ctl><alt><f2>, creates a RAID 1, and partitions it, regular MBR (they're small). 1G for /boot as the first partition, 2G for swap as the second partition, and the rest for / as partition 3. fdisk shows the partition types correctly. Back to the GUI, select the MD drive... and /boot's fine, / looks ok... but the one for swap shows with 0 bytes. Anyone else seen this behavior? mark

google chrome future / centos 7
by Richard 18 Dec '15

18 Dec '15

I'm seeing the following banner when I start up google-chrome 48-beta (48.0.2564.48 beta (64-bit)) on my 7.2 machines: This computer will soon stop receiving Google Chrome updates because this Linux system will no longer be supported. Does this portend a support issue for chrome on centos-7 in a few months when the underlying changes make their way into their -stable (since, as I understand it/as last I remember, in the centos world we don't have benefit of the RH chromium release)?

The long answer: Because RH believes/believed that the laptop environment is/was a key part of its growth strategy. The recent phenomenon of the widespread adoption of smart phones and tablets in place of laptops may bring that into question now, but the move to laptops was a deliberate business choice in my opinion. It remains to be seen whether or not RH can have its cake and eat it too. Sysadmins tend to be rather prickly people when it comes to people and things that appear to waste their time. It seems to me a strategy of dubious worth aggravating ones installed based chasing a chimera. However that may be, the world moves on and we perforce move with it or are left behind. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

CentOS-7 Security Updates
by Дмитрий Тесёлкин 18 Dec '15

18 Dec '15

Hi all, I'm trying to clarify the security updates policy for older CentOS-7 releases. There is a number of servers I'm supporting that are running CentOS-7 1503. When 1511 was released several days ago I've tried to upgrade several of those, but failed. I've got some strange errors with e1000 virtual NIC being restarted frequently with 'tx unit hang' errors. Anyway, it's not the thing I'd like to discuss here. What I'd like to know is the answer to the question "will there be any security updates for CentOS-7 1503, and how long"? I was searching on a wiki, but couldn't find anything clear enough. What I've found is the phrase in 1511 announcement letter This release supersedes all previously released content for CentOS Linux 7, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes. This makes me think that there will be no security updates for 1503 and the only way to get them is to upgrade to 1511, but I'd like to find any proof. Unfortunately, there is nothing about this in Release Notes :( -- Regards, Dmitry Teselkin

Today's Topics: 1. Announcing release for Ruby 1.9.3, 2.0.0, 2.2 and Ruby on Rails 3.2, 4.0, 4.1 on CentOS Linux 6 x86_64 SCL (Honza Horak) 2. Announcing release for Python 2.7, 3.3 and 3.4 on CentOS Linux 6 and 7 x86_64 SCL (Honza Horak) ---------------------------------------------------------------------- Message: 1 Date: Thu, 17 Dec 2015 14:33:18 +0100 From: Honza Horak <hhorak(a)redhat.com> To: centos-announce(a)centos.org Subject: [CentOS-announce] Announcing release for Ruby 1.9.3, 2.0.0, 2.2 and Ruby on Rails 3.2, 4.0, 4.1 on CentOS Linux 6 x86_64 SCL Message-ID: <5672B99E.6060600(a)redhat.com> Content-Type: text/plain; charset=utf-8; format=flowed I am pleased to announce the immediate availability versions 1.9.3, 2.0.0, and 2.2 of the Ruby, and versions 3.2, 4.0 and 4.1 of the Ruby on Rails, now also on CentOS Linux 6 x86_64, delivered via a Software Collection (SCL) built by the SCLo Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo) This is an addition for the Ruby collections that are already available for CentOS 7 (https://lists.centos.org/pipermail/centos-announce/2015-November/021501.html) QuickStart ---------- You can get started in three easy steps (example of Ruby 2.2 and Ruby on Rails 4.1): $ sudo yum install centos-release-scl $ sudo yum install rh-ruby22 rh-ror41 $ scl enable rh-ruby22 bash At this point you should be able to use ruby just as a normal application. An examples of commands run might be: $ ruby my-app.rb $ gem install activeresource $ bundle In order to view the individual components included in this collection, including additional rubygems plugins, you can run: $ sudo yum list rh-ruby22\* rh-ror41\* The rh-ror41 collection relies on the rh-ruby22 collection and the ror40 collection relies on the ruby200 collection, so the Ruby collections will be also installed when the Ruby on Rails collection is installed. About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The collection rh-ruby22 delivers bundler and version 2.2 of the Ruby interpreter, while the collection rh-ror41 delivers version 4.1 of the Ruby on Rails framework that allows to create and run applications in Ruby or Ruby on Rails framework. The collection ruby200 delivers version 2.0.0 of the Ruby interpreter, while the ror40 collection delivers version 4.0 of the Ruby on Rails framework and bundler. The collection ruby193 delivers version 1.9.3 of the Ruby interpreter, bundler and version 3.2 of the Ruby on Rails framework. Some of the most common rubygems are also included in the collections as RPMs, the rest may be installed using bundler or gem tools. For more on the Ruby and Ruby on Rails, see https://www.ruby-lang.org, http://rubyonrails.org or https://rubygems.org. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the Ruby and Ruby on Rails collections being released here, we also build and deliver databases, web servers, and language stacks including multiple versions of PostgreSQL, MariaDB, Apache HTTP Server, NodeJS, Python and others. Software Collections SIG release was announced at https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html You can learn more about Software Collections concepts at: http://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto get involved and help with the effort. We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: https://www.centos.org/community/calendar) for an informal open forum open to anyone who might have comments, concerns or wants to get started with SCL's in CentOS. Enjoy! Honza SCLo SIG member ------------------------------ Message: 2 Date: Thu, 17 Dec 2015 14:52:58 +0100 From: Honza Horak <hhorak(a)redhat.com> To: centos-announce(a)centos.org Subject: [CentOS-announce] Announcing release for Python 2.7, 3.3 and 3.4 on CentOS Linux 6 and 7 x86_64 SCL Message-ID: <5672BE3A.8060506(a)redhat.com> Content-Type: text/plain; charset=utf-8; format=flowed I am pleased to announce the immediate availability of versions 2.7, 3.3 and 3.4 of the Python on CentOS Linux 6 x86_64 and CentOS Linux 7 x86_64, delivered via a Software Collection (SCL) built by the SCLo Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo) QuickStart ---------- You can get started in three easy steps (example of Python 3.4): $ sudo yum install centos-release-scl $ sudo yum install rh-python34 $ scl enable rh-python34 bash At this point you should be able to use python just as a normal application. An examples of commands run might be: $ python my-app.py $ easy_install Flask $ easy_install Django $ bundle In order to view the individual components included in this collection, including additional python modules, you can run: $ sudo yum list rh-python34\* About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The collections rh-python34, python33 and python27 deliver versions 3.4, 3.3 and 2.7 of the Python interpreter, pip installer (except python33, which does not include pip) and some other modules that are also included in the collections as RPMs. For more on the Python, see https://www.python.org/. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the Python collections being released here, we also build and deliver databases, web servers, and language stacks including multiple versions of PostgreSQL, MariaDB, Apache HTTP Server, NodeJS, Ruby and others. Software Collections SIG release was announced at https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html You can learn more about Software Collections concepts at: http://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto get involved and help with the effort. We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: https://www.centos.org/community/calendar) for an informal open forum open to anyone who might have comments, concerns or wants to get started with SCL's in CentOS.

Setting up PXE server
by david 18 Dec '15

18 Dec '15

Folks On a lark, I am trying to set up a PXE server so I can use network boots to load new computers {some of which are virtual) at home. It's more of an intellectual exercise than a work necessity. I've read several "how to" documents, and even the one on the RedHat site doesn't help. (For example, it refers to /etc/xinet.d instead of /etc/xinetd.d, and the careless references continue elsewhere.) My goal is to make it possible to load a computer using network boot with the equivalent of the "net-install" of Centos 7. My gateway computer serves as a DHCP and (internal) DNS server for my in-house machines. Are there any good references, or working examples I could look at? My gateway is running Centos 6, but I'm hoping the model will work when I convert the gateway to Centos 7. Thanks David
