Centos 8 and logwatch
by Blaž Bogataj 14 Nov '20

14 Nov '20

Hello I am trying to get logwatch working on CentOS 8. System is fully updated. Usually install minimal version and then add only necessary with yum. On CentOS 7: install logwatch and get daily logwatch report on mail. On CentOS 8: install logwatch but no way to get mail. Am I doing something wrong? Or miss something? Thanks in advance Blaz

yum update security updates only
by Eric Chennells 14 Nov '20

14 Nov '20

Hello, I'm trying to do a yum update and only apply the security patches. I'm aware of yum update --security , however when I do that it fails to install any updates. I've tried this on a fresh 7.8.2003 (core) system, as well as the Centos 7 AMI on AWS, specifically ami-04a25c39dc7a8aebb and I get the same results. There are definitely security updates to apply. For each package which needs to be updated, it lists "<package name>" from updates removed (updateinfo). Does anyone know what's going on here? Thanks, Eric

Today's Topics: 1. Release for CentOS Linux 7 (2009) on armhfp aarch64 i386 ppc64 ppc64le and power9 (Pablo Sebasti?n Greco) 2. Release for CentOS Linux 7 (2009) on the x86_64 Architecture (Johnny Hughes) ---------------------------------------------------------------------- Message: 1 Date: Thu, 12 Nov 2020 09:31:25 -0300 From: Pablo Sebasti?n Greco <pgreco(a)centosproject.org> To: centos-announce(a)centos.org Subject: [CentOS-announce] Release for CentOS Linux 7 (2009) on armhfp aarch64 i386 ppc64 ppc64le and power9 Message-ID: <9f9bc188-2372-b845-e424-0d9e30c74d53(a)centosproject.org> Content-Type: text/plain; charset=utf-8; format=flowed I am pleased to announce the general availability of CentOS Linux 7 (2009) for across our alternative architectures. Effectively immediately, this is the current release for CentOS Linux 7 and is tagged as 2009, derived from Red Hat Enterprise Linux 7.9. As always, read through the Release Notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 - these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from the users. ---------- Updates, Sources, and DebugInfos Updates released since the upstream release are all posted, across all architectures. We strongly recommend every user apply all updates, including the content released today, on your existing CentOS Linux 7 machine by just running 'yum update'. As with all CentOS Linux 7 components, this release was built from sources hosted at git.centos.org. In addition, SRPMs that are a byproduct of the build (and also considered critical in the code and buildsys process) are being published to match every binary RPM we release. Sources will be available from vault.centos.org in their own dedicated directories to match the corresponding binary RPMs. Since there is far less traffic to the CentOS source RPMs compared with the binary RPMs, we are not putting this content on the main mirror network. If users wish to mirror this content they can do so using the reposync command available in the yum-utils package. All CentOS source RPMs are signed with the same key used to sign their binary counterparts. Developers and end users looking at inspecting and contributing patches to the CentOS Linux distro will find the code hosted at git.centos.org far simpler to work against. Details on how to best consume those are documented along with a quick start at : http://wiki.centos.org/Sources Debuginfo packages are also being signed and pushed. Yum configs shipped in the new release file will have all the context required for debuginfo to be available on every CentOS Linux install. 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. Note that older content, obsoleted by newer versions of the same applications are trimmed off from repos like Extras/ and Plus/ However this time we have also extended this to the SIG content hosted at mirror.centos.org, and some older End of Life content has been dropped. Everything we ever release, is always available on the vault service for people still looking for and have a real need for it. ---------- Special notes Altarch kernel: After RedHat's decision to deprecate power9 and aarch64 releases during the 7.7 cycle, and our decision to keep building them with the others (using the kernel from RHEL8), we decided to keep down this road. As 7.x and 8.x releases are not in sync, released kernel is 4.18.0-193.28.1 (8.2), but we're working on updating it to 4.18.0-240 (8.3) soon. ---------- Download In order to conserve donor bandwidth, and to make it possible to get the mirror content sync'd out as soon as possible, we recommend using torrents to get your initial installer images: Details on the images are available on the mirrors in a file called 0_README.txt next to the isos. That file clearly highlights the difference in the images, and when one might be more suitable than the others. Altarch images can be downloaded at : http://mirror.centos.org/altarch/7/isos/ sha256sum for ppc64 1f53ccce8867412a91eca3d0dd99333ebef871ffba3b6fb3af7eb14e280dc653 CentOS-7-ppc64-Everything-2009.iso dbc2d0609140f5d689dd16cdb64bfa181bf2c31f72ff41b9ab9dd5241dd74e0e CentOS-7-ppc64-NetInstall-2009.iso 2cae62d1e24965de6d62c8031d0be745f836c99f9640184055fc4d99e29be966 CentOS-7-ppc64-Minimal-2009.iso sha256sum for ppc64le 1e1f4a7cebd9fa99af5de34543ae8d874c2fa2ac9ca16b17dbef85a7f36f8ea4 CentOS-7-ppc64le-Everything-2009.iso 76423e534281666d00c0989ab7e4cb48e0b412207a9e8fd6269bfef23a7e71c7 CentOS-7-ppc64le-NetInstall-2009.iso 145286cee095acc549b6fb9ebcaa394bb6d4919b7f95a0b0aa4a707a57ea80ed CentOS-7-ppc64le-Minimal-2009.iso sha256sum for power9: d7b93fe2c33dd4ed01c1b83c7abd20d20e5a46e9da469c1df1f506f19f1278b3 CentOS-7-power9-Everything-2009.iso 4795492d5361268aad79be27123c78909925f5648489f790718df6d6b7c0b039 CentOS-7-power9-NetInstall-2009.iso e4bd38480e65a4462004f30f69c4b193c687e77b7ad96d567c33581a64873568 CentOS-7-power9-Minimal-2009.iso sha256sum for i386: dd238357e1750cfb25fc87e5c21891598599bf5df3ee2a749a6fd1a8fe5ec937 CentOS-7-i386-Everything-2009.iso 96c3ae101f200cac2c0d6d03a1642d69cc8f501a568ce2cc3e5ffdfdc090145f CentOS-7-i386-NetInstall-2009.iso bcbde5d345c5013fa618c38380765547be01a354883b3055f32d7067dd7b5bca CentOS-7-i386-Minimal-2009.iso shasum256 for aarch64 / ArmServer: b898822822fd5ffacc8da074adcd6b882ac0f73a269111b15871e16c2ce9d774 CentOS-7-aarch64-Everything-2009.iso 3c53c686d72649adc9afde1865b3f7fa79212966f387634eaf249a66fccfec53 CentOS-7-aarch64-NetInstall-2009.iso 1bef71329e51f9bed12349aa026b3fe0c4bb27db729399a3f9addae22848da9b CentOS-7-aarch64-Minimal-2009.iso 54951b0ba40065931d39c6051a1c91cedebd6e2a0694242595faa39424a25e1b images/CentOS-Userland-7-aarch64-generic-Minimal-2009-sda.raw.xz 99ef70e48d0499e2b59ab45eafe67581bcc8fa997638e936852f0f6255995faf images/CentOS-Userland-7-aarch64-RaspberryPI-Minimal-4-2009-sda.raw.xz sha256sums for armhfp: d2c647d265c075727714fc30b916a6f5a48ec54e980d75807c4cfdfc31da0e13 CentOS-Userland-7-armv7hl-generic-GNOME-2009-sda.raw.xz 339f9ead25bde5433a6146e05ad87f29a0ac0bd83a927e7b827177897e24208c CentOS-Userland-7-armv7hl-generic-KDE-2009-sda.raw.xz 1b99b4e73427e3e4973a358271e8d1582c23eb31c21fbd732762488bec366348 CentOS-Userland-7-armv7hl-generic-Minimal-2009-sda.raw.xz e83bc778d41221b575066f14e9aa42c47cdb64e4bf6df48d790d438766a41275 CentOS-Userland-7-armv7hl-generic-Minimal-lpae-2009-sda.raw.xz f45fcaabf55e3453ac37faed76b201716e4585a5de049b56dac81dbd36496d64 CentOS-Userland-7-armv7hl-RaspberryPI-GNOME-2009-sda.raw.xz 96b27c95f9b81f68db8e6ebeb3a3ef38daf4da88f82f47e64e1b1b9c2574c982 CentOS-Userland-7-armv7hl-RaspberryPI-KDE-2009-sda.raw.xz 38953b1c8580fe9a7ed740960a3965b378e7be56dc4b1563b3b329b3614a03c4 CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-2009-sda.raw.xz dd5e038337fb564b2f6cb45302c8d5aa1c7b92e8e67655d42b9368426a5d05b9 CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw.xz a6555b0754b119c1ee15f81ae258c9deb8e89cf0aec8e679b660a42d67c75b8f CentOS-Userland-7-armv7hl-RootFS-Minimal-2009-sda.raw.xz -------- Additional Images The container, Vagrant, Cloud and Atomic Host images are being prepared and will be released in the next few days.

Using anaconda gui without mouse
by Gianluca Cecchi 13 Nov '20

13 Nov '20

Hi, I should use Anaconda gui in CentOS 8.2 graphical way but the idrac doesn't map the mouse. What are the shortcuts for using only a keyboard? In particular it seems I'm blocked in the partitions page Any time I select one and press enter to configure the right side details/parameters, I don't find a way then to come back to the left side and move up/down to select another partition and configure its parameters. I would like to use it and not text install. Thanks, Gianluca

I had two models in my head: 1) The Frescobaldi playback module did the MIDI-> sound conversion. 2) The virtual card passed the signals on to the physical card. Perhaps your third model is correct. -- J Martin Rushton MBCS

Unable to get dummy interfaces to persist across reboots in CentOS 8
by Frank Even 13 Nov '20

13 Nov '20

Hello all, hoping someone can help me out here. I cannot get dummy interfaces on a new Cent8 build to persist across reboots. On Cent7 - this is the process I use: Create Dummies: # cat /etc/modules-load.d/dummy.conf dummy # cat /etc/modprobe.d/dummyopts.conf options dummy numdummies=4 # ip link add dummy0 type dummy ## - repeating a/ ascending dummyN adapters for as many needed # service network start # dracut -f Now this was different than even how 6 handled it, forget how I finally dug that up (possible I even asked here). I've applied this same configuration to a Cent8 box I'm trying to stand up and it all appears to work fine, but unlike the Cent7 boxes, when the Cent8 box comes back up, all the dummy adapters are missing. I've been searching all over trying to find some documentation on this to no avail. I'm hoping someone has some suggestions here to help out. Thanks, Frank

I need to schedule a process/program every hour on the hour between 9am and 4pm on the 2nd through the 9th of each month except on Saturday and Sunday. So, I tried this entry: 0 9-16 2-9 * 1-5 ./myprog.sh Unfortunately it runs outside of the 2nd through the 9th and still runs on Sat. through Sun. Is there a way to do this (outside the program itself)? -Frank

MIDI on a VM
by J Martin Rushton 12 Nov '20

12 Nov '20

I have an application (Frescobaldi/Lilypond) that generates and plays MIDI files. Due to problems with flatpak I can only run it on C8 or Fedora, both of which live on VMs. The host is running C7. I've tried "adding hardware", specifically a virtual sound card, to the VMs, but still they remain silent. How do I connect the virtual sound cards to the physical sound card so that I can hear the music? Thanks, Martin -- J Martin Rushton MBCS
