XRDP idle disconnect
by Todor Petkov 27 Sep '19

27 Sep '19

Hello, I have a machine with Centos7, Plasma desktop and XRDP. Many people log in the machine, and then press 'X' of the rdp window, instead of logging off. Is there a way to automatically log off their sessions, similar to MS Windows setting? Thanks,

CentOS 8 creates /boot with ext4
by Anand Buddhdev 27 Sep '19

27 Sep '19

I just installed CentOS 8 in a VirtualBox VM, to explore it. Immediately, I noticed something strange. I insatlled it using a kickstart file, whose partitioning section is this: zerombr clearpart --all --initlabel reqpart --add-boot part pv.01 --ondisk=/dev/sda --size=1 --grow volgroup vg01 pv.01 logvol / --name=lv_root --vgname=vg01 --size=1 --grow bootloader --driveorder=sda On CentOS 7, this resulted in an XFS-formatted /boot filesystem. In CentOS 8, this created an EXT4-formatted /boot filesystem. I looked through RHEL 8's release notes and other documentation, but could not find any place that mentions this change. Does anyone know if this is deliberate, or a bug of some kind? Regards, Anand

LVM and thin snapshots
by Georgios 27 Sep '19

27 Sep '19

Hi there! Im new here. Im trying to install Centos 8 on my laptop. I also want to have a contingency plan in case something brakes. My first thoughts were to use LVM. The idea is that i would take multiple snapshots of the system during the day/week and will keep them for a short time. I read RHEL documentation about how lvm works and pretty much understand how to manage the above scenario with LVM snapshots and encryption. If i understood lvm snapshots will cause delay the system after multiple snapshots. The best way to avoid it is using thin snapshots. At rhel documentation it says that is possible for a non thin volume to get a thin snapshots. [Correct me if my above assumptions are wrong or if there is a better solution for my purpose.] So i created a group with 3 volumes groups and one thin pool. Im trying to take a snapshot and i get the message. "Cannot use writable LV as the external origin." I read somewhere that i should change it to read only and then take a snapshot. Although that would be a problem i just try it to see if it works. Then i got the message "Cannot use active LV for the external origin" Any ideas??? Thanks in advance Georgios

For those who come across this thread, I've found the exact list of changed and dropped package between rhel:7 and rhel:8: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/ht… Too bad that the "note" column is empty in the dropped package table. NO word about reason or possible alternatives. Also too bad that those drops were not advertised before release so developers could think about migrating there code. That would have helped me a lot if I had knew that docbook-utils-pdf would be dropped....I would have searched for an alternative long ago. Olivier.

Hello All, I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I’m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you, Xinhuan Zheng

Missing packages in centos8 mirrors or do I miss something?
by LAHAYE Olivier 26 Sep '19

26 Sep '19

Hi, I need to port OSCAR Cluster and SystemImager softwares to centos8, but I miss a lot of package that seems to be built for centos-8. For example, I cant find docbook-utils and docbook-utls-pdf while I see them here: https://koji.mbox.centos.org/koji/buildinfo?buildID=651 I’ve installed epel-release and elrepo-release and centos-release-stream. Do I miss something or is it a matter of time due to mirro syncs? I misse btrfs packages, perl-Tk packages, docbook packages and many more that I can find on https://koji.mbox.centos.org/koji/builds Where am I wrong? PS: I’m running CentOS-8 in docker (roboxes/centos8 wainting for official centos:8 container). (I think that my issue is not related to the container though as I can’t find packages on mirror repos. -- Olivier LAHAYE

USB of ISO image
by Jerry Geis 26 Sep '19

26 Sep '19

Hi I did the dd iso to my USB. all is fine. I can mount the second partition (which is not iso 9660) and edit the grub.cfg file. Question is what do I run after that so my new menu option appears ? grub2-install /dev/sdd Is that the correct command to get grub to notice my new file ? Assuming sdd is the USB disk of course. Thanks, jerry

USB thumb drive for CentOS 7.7 to install
by Jerry Geis 26 Sep '19

26 Sep '19

I took the "everything" iso and did the dd command to my 16G thumb drive. I booted and entered my usual ks=http://xxx on the boot line. All good so far. It gets my kickstart file and installation begins. At some point it says Installing libreoffice-opensymbol-fonts (492/1948) Retrying download of 1:libreoffice-opensymbol-fonts-5.3.6.1-21.el7.norarch then after 10 retries it fails. I have verfied this file is on my USB disk, I have re-downloaded from different mirror, the Everything file, dd that to my USB disk, tried the re-install and still the error. I don't know what to try next. Jerry

CentOS 8
by mark 25 Sep '19

25 Sep '19

I just skimmed through the deprecated, and there's a *lot*. But one hit me in the face: if you make a change to /etc/nsswitch.conf, you need to REBOOT THE SERVER? Ok, did this come from Redmond?* Oh, and I note virt-manager replaced by cockpit. Can someone pass along a little note: Sybase has had, for a bunch of years, a required program... called cockpit. I think they've got the name by priority.... * I thought that "your cursor has moved; please reboot Windows to have this change take effect was a joke... until, about 5-6 years ago, I found in trying to set up samba at home on Win 8 that if I changed the workgroup name... it required Windows to be rebooted. So... really? nsswitch.conf, and reboot? Now I think I'll install C 7 to dual boot on my lady's workstation, rather than 8. mark "or my manager this I should go to ubuntu, which I dislike...." mark

Today's Topics: 1. Release for CentOS Linux 8 and CentOS Streams (Karanbir Singh) ---------------------------------------------------------------------- Message: 1 Date: Tue, 24 Sep 2019 17:38:36 +0100 From: Karanbir Singh <kbsingh(a)centos.org> To: CentOS Announcements List <centos-announce(a)centos.org> Subject: [CentOS-announce] Release for CentOS Linux 8 and CentOS Streams Message-ID: <beeca6a3-6abd-2416-85e9-311571fc9990(a)centos.org> Content-Type: text/plain; charset="utf-8" We would like to announce the general availability of CentOS Linux 8 and the new CentOS Stream, on all architectures. ---------- CentOS Linux 8 This is the first release for CentOS Linux 8 and is version marked as 8.0-1905, derived from sources published by Red Hat, delivered via git.centos.org First, please read through the release notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOSLinux8 - 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 and should be the first port of call for anyone looking to use CentOS Linux 8. ---------- CentOS Stream When the CentOS Project announced it was joining forces with Red Hat in January 2014, we put an emphasis on how the new relationship would ?(drive) forward development and adoption of next-generation open source technologies?: https://www.redhat.com/en/about/press-releases/red-hat-and-centos-join-forc… In the intervening years, the Project has grown to deliver not just a Linux distribution, but an entire set of sub-communities using new services in support of development work done on top of that distro. Special interest groups (SIGs) have provided a base for layered projects to develop on a stable platform. Additionally, CI/CD, the community build system, better Git repository hosting, and container pipelines, amongst others, have brought modern code and development practices to the broader CentOS community. With the introduction of CentOS Stream https://wiki.centos.org/Manuals/ReleaseNotes/CentOSStream we are excited to continue working with Red Hat http://redhat.com/en/blog/transforming-development-experience-within-centos to bring you the biggest step forward the CentOS Project has ever undertaken. CentOS Stream is a rolling-release Linux distro that exists as a midstream between the upstream development in Fedora Linux and the downstream development for Red Hat Enterprise Linux (RHEL). It is a cleared-path to contributing into future minor releases of RHEL while interacting with Red Hat and other open source developers. This pairs nicely with the existing contribution path in Fedora for future major releases of RHEL. In practice, CentOS Stream will contain the code being developed for the next minor RHEL release. This development model will allow the community to discuss, suggest, and contribute features and fixes into RHEL more quickly. To do this, Red Hat Engineering is planning to move parts of RHEL development into the CentOS Project in order to collaborate with everyone on updates to RHEL. There will not be a CentOS Stream for versions released in the past, this is only a forward-looking version target. Please read through the release notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOSStream - 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 for both distributions are being built and will be online in the next few days to catchup. Sources and debuginfo for all the released content is also available online at mirror.centos.org and vault.centos.org; In the coming days, we will work to get the cbs.centos.org service enabled for both the new distributions, and encourage the SIG's to start considering their executions plans forward. ---------- 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: Get the torrent now : http://mirror.centos.org/centos/8/isos/x86_64/CentOS-8-x86_64-1905-dvd1.tor… SHA256 707a66357f72eb822ca113991f3bb86a1ac1ed5fbc2fa5d968ed25fb48ee985c http://mirror.centos.org/centos/8-stream/isos/x86_64/CentOS-Stream-x86_64-d… SHA256: 88604a95189f91162d1f89f0ac7436f3413812506a41b8ec286baeaa833b1e91 Images, sizes and their SHA256Sum's: CentOS-8-x86_64-1905-boot.iso: 559939584 bytes SHA256 a7993a0d4b7fef2433e0d4f53530b63c715d3aadbe91f152ee5c3621139a2cbc CentOS-8-x86_64-1905-dvd1.iso: 7135559680 bytes SHA256 ea17ef71e0df3f6bf1d4bf1fc25bec1a76d1f211c115d39618fe688be34503e8 CentOS-8-ppc64le-1905-boot.iso: 567736320 bytes SHA256 9062ae0d892126f57429c3194143e6e6e5485e5f32834e03d849bf5cf075ca7a CentOS-8-ppc64le-1905-dvd1.iso: 6376304640 bytes SHA256 bfd27297da1ddc1185a08fc65e46c58efebf51b25758ff8f12d29a6214aeae39 CentOS-8-aarch64-1905-boot.iso: 520048640 bytes SHA256 18a211a826bd3dd4d034ddc529303bc2b5dc6e1b63ea311644d7698e7b67fb3e CentOS-8-aarch64-1905-dvd1.iso: 5150640128 bytes SHA256 c950cf7599a2317e081506a3e0684f665ef9c8fe66963bf7492595d7c6ccc230 CentOS-Stream-x86_64-boot.iso: 558891008 bytes SHA256 e38192400212796085b7996f21828aa8f8a72d44b64059572eb8c725e13be4cc CentOS-Stream-x86_64-dvd1.iso: 8572108800 bytes SHA256 559715017959f5967d2b9876bd27f46d8a740e1d02f59dfb8fd5e7114dd5cc79 The iso files are also available for direct download from http://mirror.centos.org/centos/8/isos/x86_64 and http://mirror.centos.org/centos/8-stream/isos/x86_64 Other media, including container, cloud, live media etc will be posted in the near future. ---------- Events We try and organise Dojo's in various parts of the world as a one day event, to bring together people who use CentOS and others who are keen to learn about CentOS. The day's focus is on sharing technical knowledge and success stories. Its also a great place to meet and talk about upcoming technologies and learn how others are using them on CentOS. Dojo at fosdem - https://wiki.centos.org/Events/Dojo/Brussels2020 Please track the page at https://wiki.centos.org/Events/ for upcoming events, and if you would like to help organise something, do get in touch with us. ---------- Getting Help The CentOS ecosystem is sustained by community driven help and guidance. The best place to start for new users is at http://wiki.centos.org/GettingHelp ---------- Thanks I'd also like to thank our donors and sponsors for their continued support for the project. Additionally, the CentOS QA team, the Core SIG team and all the associated SIG's. And thanks to everyone who contributed with ideas, code, test feedback and promoting CentOS into the ecosystem. Enjoy! - -- Karanbir Singh, Project Lead, The CentOS Project +44-207-0999389 | https://www.centos.org/ | twitter.com/CentOSProject

Video projector vs. onboard video card
by Nicolas Kovacs 25 Sep '19

25 Sep '19

Hi, I have a CentOS 7 desktop client installed on an old Dell Optiplex computer with an Intel video card integrated into the motherboard. The card has a single VGA connector, and the 19" monitor is connected to it. I wonder how I could connect a video projector to this computer while keeping the monitor, in a mirroring configuration, e. g. output is the same on the video projector and the monitor. Do I have to replace my onboard video card by something like an NVidia GT710 graphic card with two video connectors ? Or is there a different solution for this?

CentOS 8 Boot.iso image DHCP4 not working?
by Young, Gregory 25 Sep '19

I'm just wondering if anyone else is not getting a DHCPv4 address in Anaconda, using the CentOS 8 Boot.iso image? I get an IPv6 Autoconfig address, but it doesn't want to pick up a DHCPv4. This is in a Hyper-V Gen2 VM, connected to the same network all my other dev VMs are on, and picking up DHCPv4 without issue. And, congratz to the CentOS team on 2 releases in a week (or so)!

24 Sep '19

I *know* there has been a lot going on, and congratulations on getting CentOS 8 out! But(!), I don't see any updates to CO 7.7.1908 in the "updates" directory on the mirrors I typically use. All the files date from Sept. 14th. Is something broken? -- *Matt Phelps* *Information Technology Specialist, Systems Administrator* (Computation Facility, Smithsonian Astrophysical Observatory) Center for Astrophysics | Harvard & Smithsonian 60 Garden Street | MS 39 | Cambridge, MA 02138 email: mphelps(a)cfa.harvard.edu cfa.harvard.edu | Facebook <http://cfa.harvard.edu/facebook> | Twitter <http://cfa.harvard.edu/twitter> | YouTube <http://cfa.harvard.edu/youtube> | Newsletter <http://cfa.harvard.edu/newsletter>

Interesting update problem
by isdtor 24 Sep '19

24 Sep '19

I had problems updating a 7.6 machine to 7.7, so I reinstalled it from scratch and applied all the 7.6 updates, then attempted the 7.7 upgrade again. It failed with the same errors. I'm wondering where the problem is? # yum update ... [hundreds of lines of the next line] warning: Unable to get systemd shutdown inhibition lock Error in PRETRANS scriptlet in rpm package 1:java-1.8.0-openjdk-headless-1.8.0.222.b10-1.el7_7.x86_64 Error in PRETRANS scriptlet in rpm package 1:java-11-openjdk-headless-11.0.4.11-1.el7_7.x86_64 Error in PRETRANS scriptlet in rpm package kmod-kvdo-6.1.2.41-5.el7.x86_64 mesa-libEGL-devel-18.3.4-5.el7.x86_64 was supposed to be installed but is not! Verifying : mesa-libEGL-devel-18.3.4-5.el7.x86_64 1/3285 [repeating for dozens or hundreds of other packages] ... Failed: [list of all upgrade packages] Of course mesa-libEGL-devel-18.3.4-5.el7.x86_64 is not installed, that's the new version. The installed version is mesa-libEGL-devel-18.0.5-4.el7_6.x86_64. Where did it all go wrong? I tried clearing the yum cache and rebuilding the rpm db, no joy. Another 7.6 machine upgraded fine, although from a smaller installed package set.

deprecations leading up to C8
by Fred Smith 24 Sep '19

24 Sep '19

Was reading the long list of things being deprecated in the RHEL 8 release notes t'other day, and saw my old friend sendmail on the list. I've stuck by her because I've learned how she likes to be stroked to get the best out of her, and quail at the thought of taking on a new MTA and having to learn it all all over again. But I guess I'm going to have to, soon or late, probably sooner than later. :( Can anyone point me to resources specifically for helping us ignorant folk in converting all the arcan-ity in sendmail.mc into something equivalent for Postfix? Thanks in advancce!

7.7.1908, interface bonding, and default route
by Carlos A. Carnero Delgado 20 Sep '19

20 Sep '19

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24 GATEWAY=10.3.20.1 DNS1=10.3.2.8 BONDING_MASTER=yes BONDING_OPTS="mode=802.3ad xmit_hash_policy=layer2 miimon=100" The slaves (two of them) are configured like TYPE=Ethernet BOOTPROTO=none NAME=bond0-slave0 DEVICE=em3 ONBOOT=yes MASTER=bond0 SLAVE=yes After booting, the routing table is 10.3.20.0/24 dev bond0 proto kernel scope link src 10.3.20.131 metric 300 with no default route configured (manually adding it will work, of course.) This machine worked perfectly before, and it did during previous upgrades and reboots. Has anyone ever had this problem before? Thanks, Carlos.

running init disconnects ssh session
by Stephen Berg (Code 7309) 20 Sep '19

20 Sep '19

Noticing a new behavior lately. Logged in via sshd and ssh keys as root to a remote system. When changing runlevels between multi-user or graphical the ssh session is disconnected. It's not a big deal but annoying if I have other tasks to do on that particular system. I've tried logging in as normal user, su to root and it still disconnects the ssh session upon either an "init 3" or "systemctl isolate multi-user.target" command. -- Stephen Berg, IT Specialist, Ocean Sciences Division, Code 7309 Naval Research Laboratory W: (228) 688-5738 <- (Preferred contact) DSN: (312) 823-5738 C: (228) 365-0162

selinux reports

20 Sep '19

Hi all! I keep getting reports from selinux, like below, and I have no clue what the app is it's talking about, nor how do figure out if it should be allowed access or not. Anyone got any advice to offer? It says: The source process: /usr/sbin/xtables-multi attempted this access: open on this file: /run/xtables.lock Having no clue what xtables-multi is, or why or even if it should be able to open that file, I am at a loss: should I take action to enable it, or not?

UEFI booting
by Jerry Geis 20 Sep '19

20 Sep '19

I installed my first UEFI disk yesterday. Seemed to go fine. CentOS 7.6 x86_64 I then took that disk "out" of that machine and put it another machine - it seems to not even boot. I put the original disk back in that machine and it boots fine. I put the UEFI disk back in the machine I built it on and it works fine. They are similar machines either and i3 and i7. Shouldn't that work? Build a UEFI disk on machine A - move it to machine B? Thanks Jerry

Postfix vs. Thunderbird on Mac OS

conflicts in updating to CR repo
by Fred Smith 20 Sep '19

20 Sep '19

Note, first of all I haven't actually updated, I'm just running "yum update" to see what conflicts, if any, I get so I can be prepared when the final 7.7 release happens. I've traditionally used the nvidia packages from elrepo, but recently enabled rpmfusion (back when I started using 7.x, I disabled rpmfusion because it took them a looooong time to get a EL7 repository up). I use the priority plugin in yum, and have elrepo at priority 50 and rpmfusion at priority 60, so the elrepo nvidia packages should "win", but yum seems to be confused about which packages to use. So now when doing yum update (with CR enabled) I get this long list of dependency issues regarding the nvidia packages. I don't see any reason to switch to the rpmfusion packages, elrepo seems to do a good job of packaging and keeping them up to date: --> Processing Dependency: xorg-x11-drv-nvidia-390xx-libs(x86-64) = 3:390.129-1.el7 for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: nvidia-settings-390xx(x86-64) = 390.129 for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: libnvidia-tls.so.390.129()(64bit) for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: libnvidia-glcore.so.390.129()(64bit) for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Running transaction check ---> Package nvidia-settings-390xx.x86_64 0:390.129-1.el7 will be installed ---> Package xorg-x11-drv-nvidia-390xx-libs.x86_64 3:390.129-1.el7 will be installed --> Processing Conflict: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 conflicts xorg-x11-drv-nvidia-390xx Removing kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo - u due to obsoletes from kmod-nvidia-390xx.x86_64 3:390.129-3.el7 - u --> Restarting Dependency Resolution with new changes. --> Running transaction check ---> Package kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo will be an update --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 ---> Package nvidia-x11-drv.x86_64 0:430.40-1.el7_6.elrepo will be updated ---> Package nvidia-x11-drv.x86_64 0:430.40-1.el7_6.elrepo will be updated --> Finished Dependency Resolution --> Running transaction check ---> Package kernel.x86_64 0:3.10.0-957.21.2.el7 will be erased ---> Package kernel-devel.x86_64 0:3.10.0-957.21.2.el7 will be erased ---> Package kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo will be an update --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Conflict: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 conflicts xorg-x11-drv-nvidia-390xx --> Finished Dependency Resolution Error: nvidia-x11-drv conflicts with 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 Error: Package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 (elrepo) Requires: nvidia-kmod = 430.50 Removing: kmod-nvidia-430.40-1.el7_6.elrepo.x86_64 (@elrepo) nvidia-kmod = 430.40-1.el7_6.elrepo Obsoleted By: 3:kmod-nvidia-390xx-390.129-3.el7.x86_64 (rpmfusion-nonfree-updates) Not found Updated By: kmod-nvidia-430.50-1.el7_7.elrepo.x86_64 (elrepo) nvidia-kmod = 430.50-1.el7_7.elrepo Available: 3:akmod-nvidia-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 Available: kmod-nvidia-430.14-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.14-1.el7_6.elrepo Available: kmod-nvidia-430.26-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.26-1.el7_6.elrepo Available: kmod-nvidia-430.34-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.34-1.el7_6.elrepo Available: kmod-nvidia-430.40-2.el7_7.elrepo.x86_64 (elrepo) nvidia-kmod = 430.40-2.el7_7.elrepo Available: 3:kmod-nvidia-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 Available: 3:kmod-nvidia-3.10.0-1062.el7.x86_64-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 You could try using --skip-broken to work around the problem Thanks in advance for advice!

What about Mate Desktop on Centos 8?
by Frank Cox 18 Sep '19

18 Sep '19

According to Twitter: https://mobile.twitter.com/CentOSProject/status/1173652996305170432 "The next version of #CentOS is being released September 24 and will be announced in all the usual places." I'm wondering about the status of the Mate Desktop. Looking under M here: https://mirror.csclub.uwaterloo.ca/fedora/epel/8/Everything/x86_64/Packages… I don't see anything about Mate. Which leads me to ask, what's its status then? I hope it hasn't died since that's what I use for all of my computers. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Effectively immediately, this is the current release for CentOS Linux 7 and is tagged as 1908, derived from Red Hat Enterprise Linux 7.7 Source Code. 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 trim'd 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. ---------- 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 at http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt - that file clearly highlights the difference in the images, and when one might be more suitable than the others. sha256sum x86_64: ba827210d4eb9313fc19120b9b85e7baef234c7f81bc55847a336114ddac20cb CentOS-7-x86_64-LiveGNOME-1908.iso 9a2c47d97b9975452f7d582264e9fc16d108ed8252ac6816239a3b58cef5c53d CentOS-7-x86_64-Minimal-1908.iso 9bba3da2876cb9fcf6c28fb636bcbd01832fe6d84cd7445fa58e44e569b3b4fe CentOS-7-x86_64-DVD-1908.iso 0ef3310d13f7fc140ec5180dc05369d2f473e802577466825205d17e46ef5a9b CentOS-7-x86_64-LiveKDE-1908.iso bd5e6ca18386e8a8e0b5a9e906297b5610095e375e4d02342f07f32022b13acf CentOS-7-x86_64-Everything-1908.iso 6ffa7ad44e8716e4cd6a5c3a85ba5675a935fc0448c260f43b12311356ba85ad CentOS-7-x86_64-NetInstall-1908.iso Information for the torrent files and sums are available at http://mirror.centos.org/centos/7/isos/x86_64 -------- Additional Images The container, Vagrant, Cloud and Atomic Host images are being prepared and will be released in the next few days. Look for an announcement posted to the centos-announce list for more information on availability for these in the coming days. ---------- Getting Help The CentOS ecosystem is sustained by community driven help and guidance. 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/CentOSProject 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 freenode.net 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! Thanks, Johnny Hughes

audit freeing multiple contexts (when running certbot)
by tony＠softins.co.uk 17 Sep '19

17 Sep '19

Apologies if it's considered off-topic, but I'm not sure in what part of the system the issue lies. So I am giving as much info as possible, not knowing which is most relevant. I have two VMs hosted on ESX, running CentOS 6.10 One has kernel 2.6.32-754.11.1.el6.i686 and the other has 2.6.32-754.18.2.el6.i686 Both have selinux, currently in permissive mode. On both machines we have noticed messages like the following appear in /var/log/messages from time to time: Sep 17 10:32:28 merlin kernel: audit(:0): major=252 name_count=0: freeing multiple contexts (1) Sep 17 10:32:28 merlin kernel: audit(:0): major=355 name_count=0: freeing multiple contexts (2) Sep 17 10:32:29 merlin kernel: audit(:0): major=252 name_count=0: freeing multiple contexts (1) Sep 17 10:32:29 merlin kernel: audit(:0): major=355 name_count=0: freeing multiple contexts (2) On further investigation, this only happens when certbot-auto runs (under python 3.4), whether or not it renews the certificate. The above instance was created by running the following command: [root@merlin ~]# date ; cd /opt/letsencrypt && ./certbot-auto renew ; date Tue Sep 17 10:32:24 BST 2019 /opt/eff.org/certbot/venv/lib/python3.4/site-packages/cryptography/hazmat/bindings/openssl/binding.py:163: CryptographyDeprecationWarning: OpenSSL version 1.0.1 is no longer supported by the OpenSSL project, please upgrade.

reconfigure centos-6.9 host to ignore missing nic
by James B. Byrne 16 Sep '19

16 Sep '19

I need to work on a host which has been offline and powered down for some time. I has CentOS-6.9 installed. At some point it had two nics, one on the motherboard (still present and working) and one as an expansion card. When booted the console displays: pciehp 0000:00:1c:0:pcie04: Failed to check link status repeatedly. How do I tell the host to ignore the missing nic or remove it from the system configuration so that the error is removed. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.

How to disable i915 module
by Ian Pilcher 15 Sep '19

15 Sep '19

I am setting up CentOS 7 on my new firewall. This will run as a head- less system, accessed via a serial console when necessary. It's only a 2GB system, so I don't see any reason to have the GPU consuming any of the RAM. I've blacklisted the i915, drm, and drm_kms_helper modules and rebuilt the initramfs, but the i915 module is still being loaded. Anyone know what might be loading the module and how I can stop it? TIA! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ========================================================================

RPMDB problem
by Fred Smith 15 Sep '19

15 Sep '19

When doing yum operations I get this message at the end of whatever yum was doing: ** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows: brscan4-0.4.8-1.x86_64 is a duplicate with brscan4-0.4.3-1.x86_64 It is true, if I do "rpm -qa | grep brscan" it shows two of them. what's the best/proper way to deal with this? -remove both, reinstall one? -remove one? which one? I don't see a feature in rpm (or yum) for removing a single one of duplicate packages. How? Thanks in advance!

File server as host for a Windows Server VM?
by miguel medalha 14 Sep '19

14 Sep '19

I hope that someone here can give some advice on the following: I have a Samba based Active Directory. A CentOS 7.6 machine runs as a file server and hosts the Windows user profiles for all the Windows workstations. Now management has decided that they need a Windows server for a couple of administrative applications, which need MS SQL Server. That would be the only role of this Windows. Since the above mentioned server has enough resources (2x Quad Core Xeon 2.66 GHz with HT and 48 GB of RAM, a dual port 10 Gb NIC) I thought of making it a host for a Windows virtual machine using KVM. Given the resources and current setup we have, at the moment it wouldn't be practical to implement both servers as VMs on top of a bare metal hypervisor. According to your experience, is there any motive why I shouldn't use such a setup? Thank you for any insights.

Opinions on using CR repository in production environments.
by Gwaland 14 Sep '19

14 Sep '19

I was wondering what people's opinions are on running the CR repository on production systems? I'm currently predisposed to not do it since it indicates it hasn't fully gone through QA yet. But from my understanding except for the alt-arch systems these are just recompiles of the redhat RPMs after debranding right? I'm Curious how other people are treating this repository since, from the sounds of it, rpms are going to be in holding here between releases. So would you treat it as a production repository or for testing only? Do we know how it's actually intended to be treated? Any opinion is appreciated.

clamd / amavisd missing socket
by Jon LaBadie 12 Sep '19

12 Sep '19

I think something along these lines appeared before but I was unable to find them. I'm on a 7.6 system, been running clamav and amavisd-new since 6 days with little problem. On a recent reboot, clamd@amavisd does not start up and fails manual start. The problem seems to be the missing socket that connects the pair, "/var/run/clamd.amavisd/clamd.socket". I believe this should be created by systemd files but I see no indication of them on my system. Anyone know which files might be missing and where to get copies? Or a work around to run clamd@amavisd and get rid of the "*** UNCHECKED ***' additions to my my Subject lines? BTW manual creation of the socket with netcat had no effect on the startup.

Increase logging verbosity of saslauthd?
by Jobst Schmalenbach 12 Sep '19

12 Sep '19

Hi CentOS 7.X, sendmail.x86_64 8.14.7-5.el7, cyrus-sasl.x86_64 2.1.26-23.el7 There are conflicting message on how to increase the logging of saslauthd. I know I can do this: /usr/sbin/saslauthd -d -n0 -m /var/run/saslauthd -a pam but that requires a terminal as saslauthd logs the output to STDOUT, this is not what I want. I would like to have it started as a daemon and verbosity of logging increased into a log file. How can I increase the verbosity of logging for saslauthd? thanks -- Jobst Schmalenbach If you think knowledge is expensive, try ignorance.

NFS Server on Centos 7.6.1810 dying without reason
by Erick Perez - Quadrian Enterprises 07 Sep '19

CUPS job handling
by hw 06 Sep '19

06 Sep '19

Hi, is it somehow possible to make CUPS automatically redirect jobs, and following jobs, away from printers which can not print them to other printers that can print them until the printers that couldn't print them are again able to print them? Like I have a bunch of label printers which are all the same, and all of which are prone to run out of labels or out of ribbon every now and then. It can take hours or even days before someone can refill a printer. Hence it would be very useful if CUPS could be told something like "if printer A doesn't print, move its current job to printer B and divert all new jobs sent to A to printer B instead until A prints again". What exactly happens when a printer that is member of a class can not print a job that was sent to the class? Will the unprintable job be automatically moved to another member of the same class, or will it only be aborted and never printed? With a class of two printers and one of them running out of labels, /var/log/cups/error_log only holds: ... [Job 174733] Stopping unresponsive job. What does this mean? Has the job been printed or not? Has it been printed after I refilled the printer?
