How to do virtual IP on NetworkManager
by Jerry Geis 18 Jan '21

18 Jan '21

Hi All, I use virtual IP from time to time on CentOS 7. just take something like eth0 and make eth0:1 put in there the IP and subnet and bring up the new IP and it works. How do I do that with NetworkManager on the command line (assuming all static IP information) I do something like this from nmcli to set the static address: nmcli connection modify eth0 ipv4.method manual ipv6.method ignore autoconnect yes ipv4.addr 192.168.1.8/24 gw4 192.168.1.1 ipv4.dns 8.8.8.8 How then do I add a virtual IP? Thanks Jerry

Graphic setup issues...help wanted
by Kay Schenk 17 Jan '21

17 Jan '21

The problem. I can NOT change my screen resolution from GUI. I boot to multi-user, then get "into" graphical. First, some background. My original install of CentOS 8 -- maybe 8.2? -- about 3 months ago -- went pretty well but I kept having lockup issues. No issues with graphics using intel graphics or sound using either aplay at command line or GDM. (I also have NVIDIA which I have not configured.) I upgraded to 8.3 at some point. Still all OK with graphics but still lock up issues. At some point, I decided to start completely over and did a clean install of 8.4. I am now using CentOS8 Stream as my primary repo. Some questions? When I first boot, where is the probe of my video card done? Looking at DMESG, I couldn't determine this. When I "start" graphical, I get the following messages which are apparently related, from Xorg.1.log module loading section... [ 985.857] (II) LoadModule: "glx" [ 985.857] (II) Loading /usr/lib64/xorg/modules/extensions/libglx.so [ 985.859] (II) Module glx: vendor="X.Org Foundation" [ 985.859] compiled for 1.20.10, module version = 1.0.0 [ 985.859] ABI class: X.Org Server Extension, version 10.0 [ 985.859] (==) Matched modesetting as autoconfigured driver 0 [ 985.859] (==) Matched fbdev as autoconfigured driver 1 [ 985.859] (==) Matched vesa as autoconfigured driver 2 [ 985.859] (==) Assigned the driver to the xf86ConfigLayout [ 985.859] (II) LoadModule: "modesetting" [ 985.859] (II) Loading /usr/lib64/xorg/modules/drivers/modesetting_drv.so [ 985.859] (II) Module modesetting: vendor="X.Org Foundation" [ 985.859] compiled for 1.20.10, module version = 1.20.10 [ 985.859] Module class: X.Org Video Driver [ 985.859] ABI class: X.Org Video Driver, version 24.1 [ 985.859] (II) LoadModule: "fbdev" [ 985.859] (II) Loading /usr/lib64/xorg/modules/drivers/fbdev_drv.so [ 985.859] (II) Module fbdev: vendor="X.Org Foundation" [ 985.859] compiled for 1.20.3, module version = 0.5.0 [ 985.859] Module class: X.Org Video Driver [ 985.859] ABI class: X.Org Video Driver, version 24.0 [ 985.859] (II) LoadModule: "vesa" [ 985.859] (II) Loading /usr/lib64/xorg/modules/drivers/vesa_drv.so [ 985.859] (II) Module vesa: vendor="X.Org Foundation" [ 985.859] compiled for 1.20.3, module version = 2.4.0 [ 985.859] Module class: X.Org Video Driver [ 985.859] ABI class: X.Org Video Driver, version 24.0 [ 985.859] (II) modesetting: Driver for Modesetting Kernel Drivers: kms [ 985.859] (II) FBDEV: driver for framebuffer: fbdev [ 985.859] (II) VESA: driver for VESA chipsets: vesa [ 985.859] (EE) open /dev/dri/card0: No such file or directory [ 985.859] (WW) Falling back to old probe method for modesetting [ 985.859] (EE) open /dev/dri/card0: No such file or directory From messages I've seen on this problem, the lack of /dev/dri/card0 is the crux of the issue but I have NO idea of how it gets created.

bnxt_en :: interface renamed with a suffix
by Adrian Sevcenco 17 Jan '21

17 Jan '21

Hi! i had a very unpleasant surprise when an unconnected interface named enp97s0f1 was renamed when connected .. and after reboot i seen this in dmesg: [ 3.665192] bnxt_en 0000:61:00.1 enp97s0f1d1: renamed from enp97s0f1 does anyone have any idea what is going on? I disabled anything i could (to have a proper normal nic that do not act and do things behind the OS) like making sure that the broadcom nic is set to SF and disabled any function that could be disabled.. so why the rename? Thanks! Adrian

Security bulletins for CentOS 8 and CentOS Stream
by Salman Baset 14 Jan '21

14 Jan '21

Hello, I was wondering if security bulletins for CentOS 8 (till its EOL date at the end of 2021) and CentOS Stream will be available any time soon. I have not seen any security bulletins for these two operating systems on this page, but we have seen Red Hat security bulletins for Red Hat 8. https://lists.centos.org/pipermail/centos-announce/ Thanks Salman

LTS
by Thomas Stephen Lee 13 Jan '21

13 Jan '21

Hi, CentOS Linux can continue as Fedora LTS or something similar with a five-year life cycle. After five years, users can opt for paid upgrades. We can also work with System manufacturers to pre-install the free LTS on their products, which will increase our user base. --- Lee, Community User.

Reboot/shutdown without login
by Kenneth Porter 12 Jan '21

12 Jan '21

I installed CentOS 8 on a Dell server and it's been running fine as a headless system, admin'd remotely by ssh. Now I'd like to allow someone to shut it down at the console without logging in. Is there a way to do that? Or do I need to get the GUI working? I tried switching it into graphical mode ("systemctl isolate graphical") and the console freezes with nothing but a non-blinking text cursor at top left. The usual virtual console switching hotkeys (ctrl-alt F1-F7) don't do anything when it's hung like this. The system is still responsive in my ssh session. It doesn't recover if I switch back to multi-user target so I have to reboot it to make the console useful again. I'm guessing I'm lacking a good video driver. (It's an R720xd I inherited and the latest drivers on Dell's site are for RHEL 7.)

rare but repeating system crash in C7
by Fred 07 Jan '21

07 Jan '21

Hi all, I'm hoping someone can help me figure this out. every now and then (less than monthly, maybe every 2-4 months, or so, I'll walk up to my C7 box (my home PC) in the morning, wiggle the mouse to wake up the screen, and after a second or so, instead of a live screen, the keyboard shift-lock and scroll-lock keys light up. if I wait a few (tens of) second(s) I find it is rebooting, as the BIOS splash screen appears. it boots normally and comes up with everything apparently working fine. Note that I tend to leave myself logged in 24/7/365 since there's nobody here except my wife and myself, and she has her own Linux box. as it happened again this morning, I grabbed some lines from /var/log/messages that show the last few minutes before it rebooted and the first 3 or four statements as it began to reboot: Jan 2 08:50:12 fcshome kernel: xhci_hcd 0000:03:00.0: Looking for event-dma 00000000a9f2cb10 trb-start 00000000a9f2cb20 trb-end 00000000a9f2cb20 seg-start 00000000a9f2c000 seg-end 00000000a9f2cff0 Jan 2 08:50:13 fcshome kernel: xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 8 comp_code 13 Jan 2 08:50:13 fcshome kernel: xhci_hcd 0000:03:00.0: Looking for event-dma 00000000164858d0 trb-start 00000000164858e0 trb-end 00000000164858e0 seg-start 0000000016485000 seg-end 0000000016485ff0 Jan 2 08:51:12 fcshome dbus[1192]: [system] Activating service name='org.fedoraproject.Setroubleshootd' (using servicehelper) Jan 2 08:51:13 fcshome dbus[1192]: [system] Successfully activated service 'org.fedoraproject.Setroubleshootd' Jan 2 08:51:14 fcshome setroubleshoot: SELinux is preventing /usr/sbin/smbd from read access on the sock_file cups.sock.

I note that there was a selinux event early in this list of events, but I see those frequently and they normally don't cause a crash. if I scroll upward from this list, I find more of the same above what is shown here. The selinux event seems to be related to a SMB mount. since I have a Synology box on the LAN, and it stays mounted nearly all the time, I suspect the selinux event has something to do with that, but I have no idea why it would cause a crash once every few months. Is that selinux event something I need to fix? I'm further guessing that "xhci_hcd" has something to do with USB, am I right? If so I don't know what it would be... Clues would be greatly appreciated! Thanks in advance! Fred

Running script before reboot or shutdown
by Carlos Lopez 07 Jan '21

07 Jan '21

Hi all, I am trying to configure a script as a systemd service to run first when a shutdown or reboot is called. This script execute some scp commands to copy some files to other machines. My actual defined systemd’s file is: [Unit] Description=Remote copy some files before reboot/shutdown Before=poweroff.target halt.target shutdown.target reboot.target DefaultDependencies=no [Service] Type=simple ExecStart=/bin/true ExecStop=/usr/local/bin/remote_copy RemainAfterExit=yes [Install] WantedBy=multi-user.target But it doesn’t work. “remote_copy” is working when it is executed from root shell. I am using CentOS-8 fully patched release. Any idea what am I doing wrong? Regards, C. L. Martinez

fail2ban problems - not banning
by Gary Stainburn 06 Jan '21

06 Jan '21

Hi everyone, I've got fail2ban and firewalld set up on a C7 box, in theory protecting dovecot, exim and ssh but I'm not convinced it's doing anything. in /var/log/fail2ban.log I'm getting loads of entries such as: 2020-12-22 19:08:08,100 fail2ban.actions [1836]: WARNING [dovecot] 78.128.113.67 already banned I think this is because the actual ban is not working. I have entries such as: 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- exec: ports="0:65535"; for p in $(echo $ports | tr ", " " "); do firewall-cmd --add-rich-rule="rule family='ipv4' source address='113.110.47.81' port port='$p' protocol='tcp' reject type='icmp-port-unreachable'"; done 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- stderr: 'Error: INVALID_PORT: 0:65535' 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- returned 102 2020-12-22 19:38:27,620 fail2ban.actions [1836]: ERROR Failed to execute ban jail 'dovecot' action 'firewallcmd-rich-rules' info 'ActionInfo({'ip': '113.110.47.81', 'fid': <function <lambda> at 0x7f119f084050>, 'family': 'inet4', 'raw-ticket': <function <lambda> at 0x7f119f0845f0>})': Error banning 113.110.47.81 I've done some Googling and received lots of responses about fail2ban failures but I can't find anything relating to this.

Folks In examining the file /etc/dovecot/conf.d/10-ssl.conf I see the text line: ssl_cipher_list = PROFILE=SYSTEM Yet, I cannot find any documentation that explains what that causes, where the values are stored. I ask because I don't see that text line in other installations of Dovecot 2.3 on other distros. Can anyone point me to an explanation? David

PostgreSQL 13 on CentOS 7
by H 06 Jan '21

I am compiling an application that uses postgreSQL 13 and Qt 5.12. I have built the latter from scratch and successfully linked with libraries for postgreSQL 9.6 (the current version on CentOS 7) but have run into problems with postgreSQL 13. The server, client and libs are available in the postgres repository but I also need the devel library which in turns requires llvm5.0-devel which does not want seem to available... Has anyone successfully build an application use pg 13 or otherwise used postgresql13-devel? Thanks.

Is EPEL compatible with Stream?
by Kay Schenk 04 Jan '21

04 Jan '21

Hello all-- All good in the Stream for me. :) Because Stream will tend to be more "forward moving" than previous CentOS releases, is it still OK to set up EPEL as a repo? So far, I've only installed terminus fonts from CentOS 8 EPEL, but I'm just wondering about this. Generally, are there any cautions against enabling specific repos to use with Stream? -- ------------------------------------- "Don't let anyone dull your sparkle." MzK

units command, crazy output
by Fred 31 Dec '20

31 Dec '20

whenever I use the units command from a script, e.g.: elapsed=86500 echo elapsed time: `units "$elapsed sec" hms` elapsed time: *Currency exchange rates from 2012-10-24* 24 hr + 1 min + 40 sec the man page even says it outputs that when run without arguments. My question is why in the world does it? certainly when run from within a script doing conversions of time using the "hms" option, I don't want that to be stuck in the middle of my output. Anybody know why it does that, or how to make it quit? (I know, I use sed to filter it out, but can't understand why I should have to. Thanks in advance! Fred

Disk choice for workstation ?
by Nicolas Kovacs 27 Dec '20

27 Dec '20

Hi, My workstation is currently equipped with a pair of Western Digital Red 1 TB SATA disks in a software RAID 1 setup. Some stuff like working with virtual machines is a bit slow, so I'm thinking about replacing the disks by SSD. I'm hesitating between three different setups: 1) Use a relatively small SSD (120 to 240 GB) to reinstall the system on it. Keep the two SATA disks in a RAID 1 array and mount /home on it. 2) Use a larger SSD (500 GB to 1 TB), install everything (including /home) on it. Keep the two SATA disks in a RAID 1 array and mount them on /data for storage. 3) Get rid of the disks and go full SSD, with a 1 TB disk. Any advice from the hardware gurus on this list?

Sound/missing sof firmware in CentOS since 8.4
by Kay Schenk 23 Dec '20

23 Dec '20

Hello all -- I switched to Stream yesterday hoping it would fix some issues I'd been having with CentOS 8.4 but alas it did not. I started out installing 8.2, maybe kernel 4.18.0 -147?, on my laptop about 2 months or so ago and the sound worked fine. Now, it does not. I seem to be running into this problem... https://bugzilla.redhat.com/show_bug.cgi?id=1772498 I have located the rpm for this SOF package but as it states in this link, it can NOT be installed with my current alsa version. Thoughts? Guidance? -- ------------------------------------- "Don't let anyone dull your sparkle." MzK

Disabling a firewalld zone
by Mauricio Tavares 21 Dec '20

21 Dec '20

So I created a zone so I could put apply the same rules in a set of networks firewall-cmd --permanent --new-zone=pickles firewall-cmd --permanent --zone=ldap --add-source=192.168.102.0/24 firewall-cmd --permanent --zone=ldap --add-source=192.168.10.0/24 firewall-cmd --permanent --zone=ldap --add-source=192.168.3.0/24 firewall-cmd --permanent --zone=ldap --add-service=pickles firewall-cmd --reload Let's say I want to temporarily disable it. How can I do that? RIght now best I can do is completely delete it firewall-cmd --permanent --delete-zone=pickles firewall-cmd --reload which seems to be a bit harsh (good thing I documented my zone creation so I can just past the above commands and be done)

Questions about Stream
by Andrey 18 Dec '20

18 Dec '20

OK, we realized that the changes are final, and must somehow deal with it. Before making final decisions we need some answers. 1. What about bugs and security issues? The FAQ says: "Security issues will be updated in CentOS Stream after they are solved in the current RHEL release." Consider the scenario: a bug or security issue found in both Stream and current RHEL. It was fixed in RHEL in a few days. How fast it will be fixed in Stream? Obviously, it needs some time to port the fix to newer version of package. Days or months? Another scenario: a bug or security issue found in Stream but NOT in current RHEL. How fast it will be fixed in Stream? In a few days or in next RHEL release (up to 6 months)? 2. What to do in 2024, when Stream 8 is EOL. Perform full reinstall of all servers to Stream 9? Or there will be some kind of major version upgrade? A note about hardware: we don't know now what drivers will be dropped from RHEL and Stream 9. Bad news for server owners: in 2024 they may be forced to upgrade hardware or move to RHEL 8 because of its longer lifecycle.

CentOS 8.3 bugs
by d tbsky 18 Dec '20

18 Dec '20

Hi: just try to install CentOS 8.3. I use two sata disks and create mdadm raid1 with LVM. Normally when I want to reinstall this system, anaconda should recognize the raid1/lvm so I can reformat it. anaconda at CentOS 8.3 failed to do the job. I tried Scientific Linux 7.9 and RHEL 8.3, both can recognize installed CentOS 8.3 correctly and let me reformat it. and there is no net-snmp-perl package in CentOS 8.3 repository. although it is in RHEL 8.3. wait for next bug-to-bug distribution....

Exactly. That's why it's so weird that those people, today, think that CentOS Stream won't be usable, based on their interpretation of the official statements from Red Hat. Red Hat's statements weren't taken into consideration before, but now they're a sign of doom? > If they ... even allowed ANYONE ELSE that was not employed by Red Hat in > 2014 to even come close to learning the secrets of rebuild, no backlash > would have happened I'm going to stop you there, because the CentOS maintainers kept that process out of public visibility long before Red Hat was ever involved. If you think users should know more about the process, then you are pointing fingers at the *wrong* people. I don't want this to become a flame war. So rather than pointing fingers, let's focus on the fact that CentOS Stream promises to be developed in the open, resolving the problem that you're describing. Red Hat is fixing the thing you're complaining about. Red Hat is giving us the thing that has been requested more often, by more people, than any other change in CentOS, and the result is that the press is full of stories about users being angry, because five people on the mailing lists sent a lot of messages. (About half of the traffic in the threads on centos and centos-devel comes from five people, and various people replying to them.) > But no, as soon as Oracle started rebuilding RHEL source code Red Hat > first made things difficult for everyone to create kernels (source code > was not srpms anymore but tar?) You're misinformed. Kernels are still built from SRPM, but the archive used is no longer an upstream release with a series of patches. The reason for the change is not insidious. It's unfortunate that the pristine source + patches can't be maintained, I agree, but speaking as a developer: maintaining hundreds of patches that touch intersecting files and rebasing them all when earlier patches are updated is an incredibly difficult and time consuming task. And, if I remember correctly, applying all of those patches took almost as long as building the kernel. If it takes that long to just prepare the source code, that's a major hit to productivity when a developer needs to work on the code or build the SRPM to validate changes. And, ultimately, there's very little value in shipping those patches when the vast majority of them are already in the current version of the upstream kernel, and they're merely backported to the older release that Red Hat supports. It's an entirely different story when distributions are shipping patches that they don't push upstream, but that's not generally what you see with the kernel package.

I'm looking forward to the future of CentOS Stream
by Gordon Messmer 17 Dec '20

17 Dec '20

Personally, I think that changing focus on CentOS Stream is going to make CentOS (and maybe even RHEL) better in the same way and for the same reasons that Fedora is a better distribution than Red Hat Linux was. CentOS Stream should fix the biggest problems that CentOS has had in the past, providing a reliable, free LTS distribution with community participation. Having read the announcement, along with hundreds of reactions in blogs, forums, and mailing lists, I am of the opinion that all (or a reasonable approximation thereof) of the vocal concern is the result of the overloaded term "stable" as it applies to software distributions. If we imagine a spectrum of individuals in which one end of the spectrum is individuals whose primary occupation is in release engineering for software distributions and the other end is individuals who primarily consume software distributions, I would expect that individuals on one end to mostly use the term "stable" in the sense of compatibility and semantic versioning, and the other end to use the same term in the sense of having fewer bugs. The use of that word causes people at one end of the spectrum to infer a completely different message than people at the other end intend to communicate. If we never use the ambiguous term "stable" and instead use the terms compatibility and reliability (the two common meanings of "stable" at different ends of the spectrum), I think that various aspects of CentOS Stream will be better than CentOS, or the same as CentOS. With respect to compatibility: I think most developers are familiar with semantic versioning. Semantic versioning is used by some applications and libraries to indicate the nature and extent of changes. The version is presented numerically as Major.Minor.Revision. When new interfaces are added, the minor number is increased. Those changes don’t affect backward compatibility. When individual interfaces are changed or removed, the major number is increased. Those changes aren’t backward compatible. That allows consumers to infer that if an application is compatible with 8.1, then it is also compatible with 8.2 and later, but might not be compatible with 9.0. Red Hat Enterprise Linux applies that concept to the entire software distribution, providing independent software vendors a convenient means of communicating their compatibility. If they’ve tested their application on RHEL 8.2, then any RHEL 8 host patched to at least that release is expected to run the application. Moreover, Red Hat will continue to publish security patches to each given minor release’s channel, allowing consumers to "pin" a host to a minor release. Those hosts will not receive feature updates, but will mitigate vulnerabilities. CentOS Stream isn’t going to feature minor releases, and isn’t going to provide semantic versioning of the distribution. The same application that the vendor has validated on RHEL 8.2 will run on a fully patched CentOS Stream 8 host, but might not run on a host that isn’t fully patched. On the surface, it appears that CentOS users will lose the convenience provided by semantic versioning. I would simply point out that the CentOS developers have never supported running CentOS in any state other than fully patched. They don’t publish security information in the package repositories, and they don’t support any means of pinning a host to a minor release. For practical purposes, CentOS Stream will need to be fully patched for compatibility purposes, just like CentOS is, and will be equally suited for production purposes. To put a really find point on that: Semantic versioning is only meaningful for hosts that are not fully patched. A fully patched host is expected to be compatible with any application validated for that major release. With respect to reliability: Many of the people concerned about the change in focus refer to CentOS Stream as a "beta" for RHEL. That is not how Red Hat or the CentOS maintainers describe CentOS Stream( anywhere that I've seen), and I think it ignores most of the development, testing, and distribution pipeline. At the risk of oversimplifying that pipeline a whole lot, in the future Free Software will pass through several stages on the way to RHEL: Stage 1: (Software Development) The majority of development and testing is done in individual upstream projects, outside of Red Hat. Stage 2: (Release Development, aka Rawhide) The initial work to build and integrate individual packages with the rest of the software distribution is done in what is essentially a development branch of the software distribution. Stage 3: (Stable[1], aka Fedora) Packages that have passed through review and QA are published for general use. There is no minor release, as major releases occur every 6 months and are supported for only 13 months, anyway. Compatibility is maintained by prohibiting significant version changes for applications and libraries "whenever possible." Users expect no new features during a release, but no breaking changes either. Stage 4: (Long Term Support, aka CentOS Stream) Packages that CentOS Stream includes from Fedora have proven reliable in a variety of workloads managed by many users of Fedora. These packages are expected to be very reliable as a result of testing by their developers, by package maintainers, and by real-world users. They are included in CentOS Stream when they are ready. Stage 5: (Long Term Support with Semantic Versioning of the OS, aka Red Hat Enterprise Linux) Packages that RHEL includes from CentOS Stream have a similar level of QA, but package updates that introduce new features and interfaces are accepted only once every six months when Red Hat publishes a minor release. There’s a lot of concern that CentOS Stream will offer less reliability than RHEL, but there’s currently no reason to believe that will be true. There is no evidence that the minor releases that are part of the RHEL lifecycle improve reliability, and as far as I know that's not the reason they're used. Their function is to offer semantic versioning of the OS. CentOS Stream will probably offer the same level of compatibility and reliability that CentOS does today, and should be equally appropriate or inappropriate for production use in the future as CentOS is now in that respect. And that brings me to the one aspect where I think CentOS Stream will resolve the one major, glaring problem that CentOS has today, that most users ignore: Security. With respect to security: Today, CentOS is a release stage after Stage 5 described above. The CentOS maintainers begin work on a minor release after that release is available to RHEL consumers, and the process of rebuilding those packages is often very time consuming. CentOS maintainers have to reverse-engineer the exact order in which packages are built, with the exact set of installed and available packages in the build environment in order to ensure that the resulting package actually uses the same interfaces that RHEL’s packages do. All packages require that ordering and build environment matching, but most packages are published in small sets and ordering is much easier to identify than it is when they are published in a large batch. As a result, security updates can’t be published for CentOS while the maintainers are rebuilding the minor release, because the build dependencies aren’t available yet. Those windows occur every six months, and are typically a month or more in length. [2] Today, CentOS users accept the risk that for roughly two months out of the year, their systems may have known vulnerabilities with no patch to remediate the problem. Personally, I think that’s a huge risk that needs to be weighed against the costs of RHEL licenses whenever CentOS is used in production. The good news is that CentOS Stream looks like it won't have that problem. CentOS Stream updates still won’t be prepared early, while vulnerability details are embargoed, but there aren’t any windows in which CentOS Stream can’t immediately begin work on preparing updates once the embargo ends. That means that CentOS Stream will be as secure as CentOS is today in between minor updates, and significantly more secure than CentOS is today while its maintainers prepare minor releases. The trade-off of significantly improving security in exchange for giving up semantic versioning of the OS is a huge improvement for production purposes. In addition, the announcement of the change in focus indicates that Fedora maintainers should have much better visibility into work going on within the RHEL release engineering process, and more opportunity to participate in that work, and I look forward to that. CentOS’s big security problem has always been compounded by the lack of any external visibility into the process. Based on the information available today, I expect CentOS to be a very reliable, reasonably secure distribution of GNU/Linux with Long Term Support. And judging by Red Hat’s mention that Facebook’s internal groups either are already using an internally curated OS built from CentOS Stream, or will be using it soon, I think I’m not alone in believing that. 1: I’m using the term "stable" here because I expect it to have both common meanings: compatibility isn’t broken within a release, and the software is expected to be reliable. 2: https://en.wikipedia.org/wiki/CentOS#CentOS_version_8

Is Oracle a real alternative to Centos?
by Frank Cox 17 Dec '20

17 Dec '20

Is Oracle a real alternative to Centos? I'm asking because genuinely don't know; I've never paid any attention to Oracle's Linux offering before now. But today I've seen a couple of the folks here mention Oracle Linux and I see that Oracle even offers a script to convert Centos 7 to Oracle. Nothing about Centos 8 in that script, though. https://linux.oracle.com/switch/centos/ That page seems to say that Oracle Linux is everything that Centos was prior to today's announcement. But someone else here just said that the first thing Oracle Linux does is to sign you up for an Oracle account. So, for people who know a lot more about these things than I do, what's the downside of using Oracle Linux versus Centos? I assume that things like epel/rpmfusion/etc will work just as they do under Centos since it's supposed to be bit-for-bit compatible like Centos was. What does the "sign up with Oracle" stuff actually do, and can you cancel, avoid, or strip it out if you don't want it? Based on my extremely limited knowledge around Oracle Linux, it sounds like that might be a go-to solution for Centos refugees. But is it, really? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

https://blog.centos.org/2020/12/future-is-centos-stream/
by Rich Bowen 17 Dec '20

17 Dec '20

The future of the CentOS Project is CentOS Stream, and over the next year we’ll be shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release. CentOS Linux 8, as a rebuild of RHEL 8, will end at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux. Meanwhile, we understand many of you are deeply invested in CentOS Linux 7, and we’ll continue to produce that version through the remainder of the RHEL 7 life cycle. https://access.redhat.com/support/policy/updates/errata/#Life_Cycle_Dates CentOS Stream will also be the centerpiece of a major shift in collaboration among the CentOS Special Interest Groups (SIGs). This ensures SIGs are developing and testing against what becomes the next version of RHEL. This also provides SIGs a clear single goal, rather than having to build and test for two releases. It gives the CentOS contributor community a great deal of influence in the future of RHEL. And it removes confusion around what “CentOS” means in the Linux distribution ecosystem. When CentOS Linux 8 (the rebuild of RHEL8) ends, your best option will be to migrate to CentOS Stream 8, which is a small delta from CentOS Linux 8, and has regular updates like traditional CentOS Linux releases. If you are using CentOS Linux 8 in a production environment, and are concerned that CentOS Stream will not meet your needs, we encourage you to contact Red Hat about options. We have an FAQ - https://centos.org/distro-faq/ - to help with your information and planning needs, as you figure out how this shift of project focus might affect you.

CentOS advisories for 8 release
by Olivier Bonhomme 17 Dec '20

17 Dec '20

Hello dear CentOS community, I'm writing on this mailing list because I'm discovering CentOS 8 after several years of practice on CentOS 7. One of my main concern about a distribution is Bug Fixes and Security Fixes. For CentOS 7, all fixes where identified on CentOS-Announces lists with CESA, CEBA and CEEA which is a good thing in order to identify how a distribution can be broken, vulnerable. However, I didn't find any announcement for CentOS 8. I tried to investigate about any changes about announcement policies but I didn't find anything reliable. So I'm asking here what is exactly the status about announcements for CentOS 8 ? Is it a thing who totally disappeared replaced by Red Hat advisories or is it something different ? Or maybe it is just not planned yet ? Explanations would be very welcomed. Thanks for your answer Regards, Olivier Bonhomme

Software raid Oddity
by Paul R. Ganci 17 Dec '20

17 Dec '20

I have a CentOS 7.9 system with a software raid 6 root partition. Today something very strange occurred. At 6:45AM the system crashed. I rebooted and when the system came up I had multiple emails indicating that 3 out of 6 drives had failed on the root partition. Strangely I was able to boot into the system and everything was working correctly despite > cat /proc/mdstat also indicating 3 out of 6 drives had failed. Since the system was up and running despite the fact more than 2 drives had failed in the root raid array I decided to reboot the system. Actually I shut it down, waited for the drives to spin down and then restarted. This time when it came back the 3 missing drives were back in the array and a cat /proc/mdstat indicated all 6 drives were again in the raid 6 array. So a few questions: 1.) If 3 our of 6 drives of a raid 6 array supposedly fail, how does the array still function? 2.) Why would a shutdown/restart sequence supposedly fix the array? 3.) My gut suggests that the raid array was never degraded and that my system (i.e. cat /proc/mdstat) was lying to me. Any Opinions? Has anybody else ever seen such strange behavior? -- Paul (ganci(a)nurdog.com) Cell: (303)257-5208

What are the differences between CentOS Linux and CentOS Stream?
by Turritopsis Dohrnii Teo En Ming 17 Dec '20

Good day from Singapore, What are the differences between CentOS Linux and CentOS Stream? At the moment, I only know that CentOS 8 support will end on 31 December 2021 while Red Hat Inc will shift its focus to CentOS Stream. Is CentOS Stream going to be very similar to Fedora Linux, shipping with the latest Linux Kernel like 5.10.1? I am looking forward to hearing from you. Thank you. -----BEGIN EMAIL SIGNATURE----- The Gospel for all Targeted Individuals (TIs): [The New York Times] Microwave Weapons Are Prime Suspect in Ills of U.S. Embassy Workers Link: https://www.nytimes.com/2018/09/01/science/sonic-attack-cuba-microwave.html ******************************************************************************************** Singaporean Targeted Individual Mr. Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 14 Feb 2019 and refugee seeking attempts at the United Nations Refugee Agency Bangkok (21 Mar 2017), in Taiwan (5 Aug 2019) and Australia (25 Dec 2019 to 9 Jan 2020): [1] https://tdtemcerts.wordpress.com/ [2] https://tdtemcerts.blogspot.sg/ [3] https://www.scribd.com/user/270125049/Teo-En-Ming -----END EMAIL SIGNATURE-----

What about the AltArch repositories? (+ some experiments with aarch64 on Raspberry Pi)
by Mathieu Baudier 17 Dec '20

17 Dec '20

Hello, given the recent change in direction of CentOS, what will become of the AltArch repositories? (like CentOS 7 aarch64 and the related kernel repositories) I have been experimenting (with some success) with running a regular CentOS 8 aarch64 (ARM 64 bits) on a Raspberry PI 4 (with 4GB RAM), using the aarch64 kernel-rpi2 provided by CentOS 7 AltArch [1]. (a few more technical details below) This is a very different question than what is currently hotly discussed on this list, with the end of the bug-for-bug clone of RHEL, as there were never expectations that such settings would be supported. But on the other hand, I liked to use CentOS for innovation in a given field (mostly Java related) as its stability allowed one to go deep into one direction with "other things being equal" (contrary to Fedora, which is always moving in all directions). I guess that all these "side projects" (and SIGs, etc.) will disappear as well, won't they? Cheers, Mathieu ## More details about running CentOS aarch64 on a Raspberry Pi 4 As for my experiments with running CentOS 8 on a Raspberry Pi 4, a bit more details, so that these efforts are not completely lost. Two approaches were working : - From a plain CentOS 7 AltArch aarch64 installation, perform a CentOS 8 aarch64 install in a chroot (with the --installroot option) + a clean kernel-pi2 install from the CentOS 7 kernel-pi2 repository. Then copy the chroot to an .img file, and use this image to initialise an SD card. - From a plain CentOS 7 AltArch aarch64 installation, perform an in-place upgrade to CentOS 8 (first install dnf from EPEL, then switch the repos, and it works) The second approach had better device support on the Raspberry Pi 4 (most importantly the wifi, which was not working with the first approach), but this was probably a matter of subtle kernel / modprobe configs that were beyond my skills. I thought that I would share all this at some point, and ask for help from the CentOS AltArch developers; but I guess it is irrelevant right now. Both approaches were working equally well on the Raspberry Pi 3 (but Fedora support is good for this version, while Raspberry Pi 4 is not supported, so I tend to use Fedora aarch64 on them). As for what is actually the point of doing all this, this is not for weekend hobby tinkering, and it is relevant for server-side applications. ARM 64 bits is becoming an important platform (hence the fact that RHEL is now supporting it, MacOS will soon completely move to it, etc.) especially if one is interested in climate-friendly low-power IT, also on the server-side. But finding hardware is not easy and the (cheap) Raspberry Pi have 64-bit capable processors, even though the default distrib (Raspbian, based on Debian) does not yet support 64 bits (but they are working on it [2]). After trying many distributions, a paradox was that CentOS was actually the easiest to deploy and use in order to get some results (thanks to the work of the AltArch team!) In my case, the main interest was to test on ARM 64 bits GraalVM, the next generation Java platform, which can compile Java (and other programming languages) to native code. These builds require a lot of memory, but with an extremely slimmed down CentOS 8 and the 4 GB memory of the Raspberry Pi 4, it worked! [3] On a different layer, I could also test Eclipse SWT (Java user interface library) on this architecture (but on the plain CentOS 7 aarch64 with GNOME), and provide some quick feedback to Eclipse developers on their recent support for the whole Eclipse IDE on ARM 64 bits.

Blog article: CentOS is NOT dead

Hi, Here's an interesting read which makes a point for CentOS Stream: https://freedomben.medium.com/centos-is-not-dead-please-stop-saying-it-is-a… tl;dr: Communication about Stream was BAD, but Stream itself might be a good thing. Here's why.
