I was looking into the system's sync/shutdown/halt user accounts and found this page: <https://access.redhat.com/solutions/44682#comments> I wanted to reply to the comments I found there so I logged in. Now I can't see the comments or otherwise interact with the page. I'm using Chrome on Win10-x64 and disabled my ad blocker (uBlock Origin). I tried opening the page in an incognito window, and again I can see the comments while logged out. The same thing happens with Firefox. (This looks like a handy way to allow those with physical access to shutdown my system in an emergency. The next problem is how to restrict such logins to the console, and not allow them via ssh.)

Prevent a particular kernel from being deleted
by Frank Cox 11 Jun '21

11 Jun '21

Somewhat related to my inquiry earlier today about the disappearing sound card, I just got to wondering if there's a way to "pin" the kernel that works with the soundcard such that it won't be deleted with future updates until and unless there's a future kernel released that solves the sound card issue. "dnf versionlock" appears to almost do what I want, but it just locks a package to a particular version and doesn't allow it to be upgraded past that. I'd like to be able to install updated kernels as they are released, but somehow tell dnf to never delete kernel version 4.18.0-240.22.1.el8_3.x86_64. In the normal course of events that kernel would be deleted after a certain number of kernels are installed afterward (as specified by the installonly_limit number in /etc/dnf/dnf.conf. So is there a way to tell dnf to update kernels in the usual manner but always keep a certain installed version until otherwise instructed? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

CentOS Community Code of Conduct
by Rich Bowen 08 Jun '21

08 Jun '21

As per my email in April - https://lists.centos.org/pipermail/centos-devel/2021-April/076769.html - and per the approval of the Board of Directors, we have published the new CentOS Community Code of Conduct: https://www.centos.org/code-of-conduct/ This Code of Conduct is in effect immediately, and the reporting process described in there is in effect immediately. One note: The doc says that it is "a living document and will be updated when and if it is deemed necessary." One change that we forsee very soon is that, rather than me, as Community Architect, being the sole responsible party for reporting CoC incidents, I will be assembling a small CoC committee. While I have identified some of the people who will be part of that committee, I thought it was good to go ahead and publish the CoC as is, and modify it once that committee is all in place. Thanks to everyone that participated in the review process for this policy. --Rich, on behalf of the Board of Directors.

Fwd: Pre-announcement of an ISC DHCP security issue scheduled for disclosure 26 May 2021
by Kenneth Porter 07 Jun '21

07 Jun '21

-------- Forwarded Message -------- Subject: Pre-announcement of an ISC DHCP security issue scheduled for disclosure 26 May 2021 Date: Fri, 21 May 2021 11:44:19 -0800 From: Michael McNally <mcnally(a)isc.org> To: dhcp-announce(a)lists.isc.org Hello, dhcp-announce list subscribers, It has been a while since our last post to this list. Since the last time we posted news of a new release of ISC DHCP, Internet Systems Consortium has adopted a practice of pre-announcing expected security disclosures in order to give operators who use our products a little advance warning and planning time. For that reason, I am writing you today to let you know that a vulnerability in ISC DHCP will be publicly announced next week on Wednesday, 26 May 2021. Further details about that vulnerability will be publicly disclosed next week, and new releases of ISC DHCP that correct the vulnerability will be made available at that time. It is our hope that this pre-announcement will aid DHCP operators in preparing for that disclosure when it occurs. Yours sincerely, Michael McNally (writing for ISC Security Officer) _______________________________________________ dhcp-announce mailing list dhcp-announce(a)lists.isc.org https://lists.isc.org/mailman/listinfo/dhcp-announce

Static configuration: prevent /etc/resolv.conf from being overwritten on first reboot
by Nicolas Kovacs 07 Jun '21

07 Jun '21

Hi, Here's something that's puzzling me. Starting from a minimal installation of CentOS 7, network configuration is DHCP. I'm launching nmtui to define a static configuration. I'm providing the IP address as well as the gateway, but no DNS server. I'm quitting nmtui and I'm editing /etc/resolv.conf to provide my DNS server: # /etc/resolv.conf nameserver 192.168.0.254 I reboot my server, and I don't know why, but my /etc/resolv.conf has been overwritten: # Generated by NetworkManager So I edit this file again: # /etc/resolv.conf nameserver 192.168.0.254 And starting from here, it works, meaning /etc/resolv.conf is not overwritten on subsequent reboots. Q: how can I prevent /etc/resolv.conf from being overwritten on the initial reboot? I vaguely remember having to kill some process before editing it, but unfortunately I don't remember which one.

Upgrade to 8.4 .2105 Problems
by Alan McRae 05 Jun '21

05 Jun '21

The yum upgrade from 8.3 to 8.4 on my main machine looked as if it was working fine so I went to have a coffee. When I came back the screens were blank so I don't know what happened. On rebooting the screens are still blank. I have two graphics cards running three displays. I have a "rescue" system on the same machine that upgraded from 8.3 to 8.4 fine. The 3 screens work fine on this. I am not sure the upgrade completed properly. For example the new kernel: vmlinuz-4.18.0-305.3.1.el8.x86_64 was not present in /boot. Even worse, "yum upgrade" said there was nothing to do and would not install it. I installed the kernel package manually. /etc/redhat-release says CentOS Linux release 8.4.2105 My main question is: Where are the config files for the screen(s). This used to be something like /etc/X11/xorg.conf. Since I have a working rescue system my current plan is to compare/copy the config files. Suggestions please as to where I should start. It is difficult to work without a GUI. I have ssh access to the machine. Thanks Alan -- Alan McRae

Sound card disappears on Acer laptop with latest kernel
by Frank Cox 04 Jun '21

04 Jun '21

4.18.0-240.22.1.el8_3.x86_64 Sound works as expected. 4.18.0-305.3.1.el8.x86_64 only "dummy output" shows up under the Sound Preferences on the desktop. I guess there's a kernel bug somewhere that's causing the driver for that soundcard to not load? The lshw command (when running kernel subversion 240.22.1, i.e. the "old kernel") tells me that it has this soundcard: *-multimedia description: Multimedia audio controller product: Sunrise Point-LP HD Audio vendor: Intel Corporation physical id: 1f.3 bus info: pci@0000:00:1f.3 logical name: card0 logical name: /dev/snd/controlC0 logical name: /dev/snd/hwC0D0 logical name: /dev/snd/hwC0D2 logical name: /dev/snd/pcmC0D0c logical name: /dev/snd/pcmC0D0p logical name: /dev/snd/pcmC0D10p logical name: /dev/snd/pcmC0D2c logical name: /dev/snd/pcmC0D3p logical name: /dev/snd/pcmC0D7p logical name: /dev/snd/pcmC0D8p logical name: /dev/snd/pcmC0D9p version: 21 width: 64 bits clock: 33MHz capabilities: pm msi bus_master cap_list configuration: driver=snd_hda_intel latency=32 resources: irq:128 memory:df1a8000-df1abfff memory:df180000-df18ffff -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Today's Topics: 1. Announcing the latest release of CentOS Linux 8 (2105) (Rich Bowen) ---------------------------------------------------------------------- Message: 1 Date: Thu, 3 Jun 2021 16:52:37 -0400 From: Rich Bowen <rbowen(a)redhat.com> To: centos-announce(a)centos.org, "The CentOS developers mailing list." <centos-devel(a)centos.org> Subject: [CentOS-announce] Announcing the latest release of CentOS Linux 8 (2105) Message-ID: <8d631d5c-8df9-fec9-82fe-ee27b45bea89(a)redhat.com> Content-Type: text/plain; charset=utf-8; format=flowed Release for CentOS Linux 8 (2105) We are pleased to announce the general availability of the latest version of CentOS Linux 8. Effectively immediately, this is the current release for CentOS Linux 8 and is tagged as 2105, derived from Red Hat Enterprise Linux 8.4 Source Code. As always, read through the Release Notes at: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.2105 - 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 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 8 machine by just running 'dnf update'. As with all CentOS Linux 8 components, this release was built from sources hosted at git.centos.org. 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/dnf-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 have been 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 8, 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 trim'd off from repos like extras/ and centosplus/ ---------- Download We produced the following installer images for CentOS Linux 8 # CentOS-8.4.2105-aarch64-boot.iso: 677838848 bytes SHA256 (CentOS-8.4.2105-aarch64-boot.iso) = 106d9ce13076441c52dc38c95e9977a83f28a4c1ce88baa10412c1e3cc9b2a2b # CentOS-8.4.2105-aarch64-dvd1.iso: 7325042688 bytes SHA256 (CentOS-8.4.2105-aarch64-dvd1.iso) = 6654112602beec7f6b5c134f28cf6b77aedc05b2a7ece2656dacf477f77c81df # CentOS-8.4.2105-ppc64le-boot.iso: 722780160 bytes SHA256 (CentOS-8.4.2105-ppc64le-boot.iso) = 4a83e12f56334132c3040491e5894e01dfe5373793e73f532c859b958aeeb900 # CentOS-8.4.2105-ppc64le-dvd1.iso: 8484990976 bytes SHA256 (CentOS-8.4.2105-ppc64le-dvd1.iso) = 9cfca292a59a45bdb1737019a6ac0383e0a674a415e7c0634262d66884a47d01 # CentOS-8.4.2105-x86_64-boot.iso: 758120448 bytes SHA256 (CentOS-8.4.2105-x86_64-boot.iso) = c79921e24d472144d8f36a0d5f409b12bd016d9d7d022fd703563973ca9c375c # CentOS-8.4.2105-x86_64-dvd1.iso: 9928966144 bytes SHA256 (CentOS-8.4.2105-x86_64-dvd1.iso) = 0394ecfa994db75efc1413207d2e5ac67af4f6685b3b896e2837c682221fd6b2 Information for the torrent files and sums are available at http://mirror.centos.org/centos/8/isos/ -------- Additional Images Vagrant and Generic Cloud images are available at: http://cloud.centos.org/centos/8/ Amazon Machine Images for Amazon Web Services are published by ID into a number of regions.

The best place to start for new users is at http://wiki.centos.org/GettingHelp We are also on social media, you can find the project: on Twitter at :http://twitter.com/CentOS on Facebook at :https://www.facebook.com/groups/centosproject/ on LinkedIn at :https://www.linkedin.com/groups/22405 And you will find the core team and a majority of the contributors on irc, on irc.libera.chat in #centos ; talking about the finer points of distribution engineering and platform enablement. ---------- Contributors This release was made possible due to the hard work of many people, foremost on that list are the Red Hat Engineers for producing a great distribution and the CentOS QA team, without them CentOS Linux would look very different. Many of the team went further and beyond expectations to bring this release to you, and I would like to thank everyone for their help. We are also looking for people to get involved with the QA process in CentOS, if you would like to join this please introduce yourself on the centos-devel list (http://lists.centos.org/mailman/listinfo/centos-devel). Finally, please join me in thanking the donors who all make this possible for us. Enjoy the fresh new release!

Hello All, At the moment im using http://mirror.centos.org/centos/8/ repo on my CentOS 8 host and I noticed, that im missing quite many new packages/updates what 8.4.2105 repo contains. Is there a possibility that they will also be transferred to on /8/ repo or should I start using /8.4.2105/ on my host ? Regards, Kimmo For Internal Use Only
