by Kaushal Shriyan 01 Dec '20

01 Dec '20

Hi, I am running CentOS Linux release 7.9.2009 (Core). Is there a way to upgrade OpenSSH version openssh-7.4p1-21.el7.x86_64 to the latest stable version openssh-server 8.4 using yum repositories or rpm binaries? Best Regards, Kaushal

CentOS and mdadm
by Nicolas Kovacs 01 Dec '20

01 Dec '20

Hi, I'm regularly using software RAID for my CentOS storage servers, either with RAID 1 or RAID 6 depending on the number of disks. Here's two questions about mdadm I've always been wondering about. 1. I'm not sure about the --metadata option. Let's say I want to create a simple RAID 1 setup, I'm usually doing it like this: # mdadm --create /dev/md/boot --level=1 --raid-devices=2 \ --metadata=1.2 /dev/sda1 /dev/sdb1 If anyone can explain the exact meaning of --metadata, I'd be grateful. Oh, and is it OK to use --metadata=1.2 in CentOS 7.x and 8.x ? 2. I'm regularly encountering the mdadm --misc option in various tutorials on the Internet. I looked it up in mdadm's manpage, but it doesn't seem to be documented. Any idea what this option does ?

Physical position of swap partition on the disk
by Nicolas Kovacs 01 Dec '20

01 Dec '20

Hi, Here's a question to the fine-tuning gurus. Yesterday while installing a fresh CentOS server, I wondered how big of a deal the physical position of the swap partition on the disk is. Here's an example of a simple MBR partitioning scheme on a legacy BIOS machine with a 60 GB SSD: * /dev/sda1: 500 MB /boot ext2 * /dev/sda2: 4 GB swap * /dev/sda3: 55 GB / ext4 In the old (Slackware) days, I created the partitions manually using fdisk. Now when I do something similar in Anaconda, I have to reason in terms of mount points. So in a similar order I create the /boot partition, the swap partition and the root partition. What happens here is that Anaconda will always invert the root and swap partitions and put the swap partition at the end of the disk. So my setup looks like this: * /dev/sda1: 500 MB /boot ext2 * /dev/sda2: 55 GB / ext4 * /dev/sda3: 4 GB swap I'd be curious to know what's the reason behind this, and if this kind of configuration detail is really significant.

Anaconda : MBR vs. GPT
by Nicolas Kovacs 28 Nov '20

28 Nov '20

Hi, I've always been a bit puzzled by the fact that Anaconda provides no option to manually create a partition table and specify if it's MBR or GPT. >From what I can tell - at least under CentOS 7.x - Anaconda will default to MBR, even if I specify a BIOS Boot partition. Maybe it switches automatically to GPT if the disk size requires it ( > 2 TB IIRC) though I don't have any corresponding hardware here to test it. Is this documented somewhere? Or is there a nifty little trick to tell Anaconda to prefer GPT partition tables?

Emulate Ghost4Linux with standard Linux commands?
by Nicolas Kovacs 28 Nov '20

28 Nov '20

Hi, I'm currently trying to solve a tricky problem, and I don't even know if it's possible. Let me describe the situation with a practical example. In my office I have a sandbox PC for testing various setups that can't be tested in a virtual machine. I'm using this machine to test various setups with the Linux distributions I'm using, namely CentOS 7, CentOS 8 and OpenSUSE Leap 15. I have a series of Ghost images of these systems on a local FTP server, and I'm using G4L (Ghost4Linux) to transfer these images to and from the server. * https://sourceforge.net/projects/g4l/ On a side note, I take care of zeroing unused disk space in order to get relatively compact disk images like this: # dd if=/dev/zero of=/0bits bs=20M ; rm -f /0bits Besides my local sandbox machine, I also have a sandbox server in a datacenter, which I'm using for testing Internet-facing stuff. I'd like to be able to do something similar with this public machine, e. g. backup the whole disk content completely agnostic in terms of partitions and file systems and send it to a public FTP server. Unfortunately I can't boot G4L on this server, since I don't have physical access to the machine. The datacenter is about 700 km from where I can live. What I can do: fire up a rescue console via an administration web interface and boot a live Linux system, either Ubuntu 16.04 or 18.04. Now here's the question. From within my live system, how could I compress my system into a compact image and then send it to a distant FTP server? And once this is done, how could I get my image back from the server?

dnf via ansible fails if baseurl is used on CentOS 8
by Thomas Eriksson 26 Nov '20

26 Nov '20

Hi, I ran into an odd issue on CentOS 8, anyone seen this? When repos are configured to use baseurl instead of mirrorlist, the ansible dnf module fails. It is as if it is ignoring the baseurl configuration. #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra baseurl=http://my.local.repo.server/$contentdir/$releasever/BaseOS/$basearch/os/ If trying to use the dnf module in ansible, dnf is still trying to find a mirror to use and fails. ansible test-build-0 -m dnf -a "name=zsh state=present" test-build-0 | FAILED! => { "changed": false, "msg": "Failed to download metadata for repo 'BaseOS': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried", "rc": 1, "results": [] } Using dnf locally from the command line works fine with baseurl If I re-configure with repos using mirrorlist again, ansible dnf works as expected. Just looking for ideas... /Thomas

Replacing SW RAID-1 with SSD RAID-1

Hi, I want to replace my hard drives based SW RAID-1 with SSD's. What would be the recommended procedure? Can I just remove one drive, replace with SSD and rebuild, then repeat with the other drive? Thanks Frank -- <listfrank1(a)gmail.com>

Xorg --configure
by Michael Hennebry 24 Nov '20

24 Nov '20

I'm currently running Centos 8 off an SD card. It, unlike F32, lets me use my monitor's full 1440 x 900. Both seem to use defaults and EDID, but F32 gets it wrong and saddles me with 640 x 480 when I can find the incantation to have it run at all. The configuration files and directories I can find are pretty much empty. How do I add --configure to the Xorg command line? 'Tis my understanding that would generate a configuration file that I could port to F32. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

installing Centos 8 to an SD card
by Michael Hennebry 24 Nov '20

24 Nov '20

I'm trying to install Centos 8 from a CD burned with Centos-8-2-2004-x86_64-boot , to an SD card in a USB SD card reader. The installer appears not to notice the card reader. Doing a df from tty2 also provides no notice of the card reader. Can what I am trying to do be done? The card currently has a German Knoppix on it. I know from experience that my machine can boot from it. How do I make this happen? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

Password manager for the command line ?
by Nicolas Kovacs 24 Nov '20

24 Nov '20

Hi, On my workstation and my laptop I'm using KeePassXC to store login credentials for my websites. The database is stored in my OwnCloud share, so it's synchronized between my two computers. Ideally I'd like to have something similar for my servers, but command-line driven. I know these tools exist but I haven't tested them yet. What I have in mind is a command-line password manager that stores the database in an encrypted database - like KeePassXC - and then I could eventually store this file in a private Gitlab repo to centralize it and access it from all my servers. Can you recommend any particular command line password manager ? Any recommendations / caveats for this kind of setup ?

Thunderbird 78.4.0 after update
by R C 23 Nov '20

23 Nov '20

Hello, after an update I ended up with Thunderbird 78.4.0, it looks a little different, which is ok, but it seems that all my descriptions and also alerts disappeared. Is that a known problem? If so, how to fix that. (btw; I am not sure if I ever installed/used lightning, but that addon/extension doesn't seem to be there anymore.) If it is a known problem, is there a way to fix that? thanks, Ron

X defaults
by Michael Hennebry 23 Nov '20

23 Nov '20

I've been trying to move from Centos 7 to fedora. My monitor is 1440x900, but fedora only believes it's 640x480. Grrrr. xrandr has not helped. I've been trying to write X configuration files to tell fedora 1440x900, but no joy. Is there a way to get X to tell me its current beliefs, very preferably in configuration file format? According to the log file on Centos, everything was defaulted or probed. It contains no numbers. My guess is that fedora has different defaults and they are wrong for me. I've had problems like this before, so I'm unwilling to install until I know I can run a live version. That makes life clunky. I have to boot to non-graphics, do my editing and change the runlevel. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

Desktop Over NFS Home Blocked By Firewalld
by Michael B Allen 22 Nov '20

22 Nov '20

Hi, Just installed CentOS 7 that serves a home dir automounted over nfs. SELinux is disabled. If I go to the client (oldish version of Fedora) doing su - username works fine and the nfs export is mounted and I can see all files and everything seems well. But trying to actually login to the desktop from the client machine does not work. It starts to login but then just hangs with a black screen. Trying to just launch libreoffice --writer from a terminal as the nfs mounted user also hangs on the spash screen. If I then go to the server and 'systemctl stop firewalld', the desktop instantly logs in fine and libreoffice works from the term. So firewalld is blocking something that the Fedora desktop needs. What is it? What services do I need to add to firewalld? Thanks, Mike

server rebooted email
by Kenneth Porter 19 Nov '20

19 Nov '20

I used to put a line in rc.local to email root that my server rebooted. Does anyone have a nice systemd unit file to do the same? Also useful would be a shutdown email with the output of uptime. (I usually do that manually when rebooting for a kernel update.)

(C8) root on mdraid
by Łukasz Posadowski 18 Nov '20

18 Nov '20

Hello everyone. I'm trying to install CentOS 8 with root and swap partitions on software raid. The plan is: - create md0 raid level 1 with 2 hard drives: /dev/sda and /dev/sdb, using Linux Rscue CD, - install CentOS 8 with Virtual Box on my laptop, - rsync CentOS 8 root partition on /dev/md0p1, - chroot in CentOS 8 root partition, - configure /etc/mdadm.conf, grub.cfg, initramfs, install bootloader on both sda and sdb drives. I think I can do first four of the above, but my CentOS installation acts strange after rebooting the server.

Intel RST RAID 1, partition tables and UUIDs
by H 18 Nov '20

18 Nov '20

I have been having some problems with hardware RAID 1 on the motherboard that I am running CentOS 7 on. After a BIOS upgrade of the system, I lost the RAID 1 setup and was no longer able to boot the system. Testdisk revealed that the partition tables had been damaged and because I had earlier saved information from fdisk, I was able to recreate the partitions. However, booting into the BIOS and recreating/synchronizing the RAID from one of the disks (took around 20 hours for 256 GB disks), I again lost the ability the boot and the partition tables were similarly damaged. Eventually I was able to boot the system again from one of the two disks and it is now up and running, now running without RAID. - Should I expect that the Intel RAID 1 setup changes the partition tables? I should add that the disks were originally created after the RAID 1 was setup. - After fooling around with testdisk (and prior to that, parted), it turned out that I had lost the disk UUID for both disks, they were both set to 000... Partition UUIDs seemed unchanged from before, including the LUKS partitions. Are disk UUIDs (not partition UUIDs) not used by Linux since I have not - yet - seen any effects of the missing disk UUIDs? Because there seems to be a couple of other issues with the motherboard, I expect to have it replaced early this week but I am still interested in learning more. Thanks.

Best practice preparing for disk restoring system
by H 18 Nov '20

18 Nov '20

Short of backing up entire disks using dd, I'd like to collect all required information to make sure I can restore partitions, disk information, UUIDs and anything else required in the event of losing a disk. So far I am collecting information from: - fdisk -l - blkid - lsblk - grub2-efi.cfg - grub - fstab Hoping that this would supply me with /all/ information to restore a system - with the exception of installed operating system, apps and data. I would appreciate any and all thoughts on the above!

why does virtual console start affect graphical start up?
by Kay Schenk 18 Nov '20

18 Nov '20

Hello all-- I have 3 CentOs 8 kernels insalled on my new machine -- 1. 4.18.0-193.14.2.el8_2.x86_6 2. 4.18.0-193.19.1.el8_2.x86_64 << using this one for this graphical boot 3. 4.18.0-193.28.1.el8_2.x86_64 Only #3 will boot without a *Virtual console can not start *error message but it hangs up trying to get into graphical mode, although it will boot to multi-user. The first 2 seem to work reaosnably well in either graphical or multi-user but I get a *Virtual console can not start *in boot messages with both of these. Does anyone know anything about this? Having a heck of a time trying to prevent lock ups. Thanks. **

Apologies - possible hardware problem?
by Jeffrey Layton 16 Nov '20

16 Nov '20

Good afternoon, I have a home workstation with an AMD CPU, Titan V GPU, 32 GB of memory, and a root SSD and /home on spinning disks. Right now it has xubuntu 18.04 on it and it would boot fine. I shut it down and restarted it to get an inventory before I put CentOS 8.2 on it. It won't boot now. It gets to the grub menu and freezes. I can't use the keyboard to select an item in the menu and I can't press enter to make it boot or press "e" to edit the boot line. It just sits there (seemingly forever). Here's what I've tred: 1. New keyboard/mouse - no change 2. Different monitor - no change 3. Booting from the CentOS 8.2 iso on a USB stick - no change 4. Replacing the TItan V card with a GT 1030 NV card - no change When booting from a USB stick, I get the BIOS splash screen and press "DEL" to get to the menu, but the menu never shows up. It just freezes. This one has me stumped. Not being able to boot from a USB stick is really puzzling. I've never seen that before. Possible bad MB? My apologies for using the list to help debug problems but since I'm moving to CentOS 8.2 I thought people might have some ideas. TIA! Jeff

mdadm raid-check
by hw 16 Nov '20

16 Nov '20

Hi, is it required to run /usr/sbin/raid-check once per week? Centos 7 does this. Maybe it's sufficient to run it monthly? IIRC Debian did it monthly. I just checked on Fedora 32. It does not run raid-check at all, at least not via a cron entry. /usr/sbin/raid-check is available, though. Is that an oversight? (I started it manually now and will check if it's run once I update to 33.)

ssacli start rebuild?
by hw 15 Nov '20

15 Nov '20

Hi, is there a way to rebuild an array using ssacli with a P410? A failed disk has been replaced and now the array is not rebuilding like it should: Array A (SATA, Unused Space: 1 MB) logicaldrive 1 (14.55 TB, RAID 1+0, Ready for Rebuild) physicaldrive 1I:0:1 (port 1I:box 0:bay 1, SATA HDD, 4 TB, OK) physicaldrive 1I:0:2 (port 1I:box 0:bay 2, SATA HDD, 4 TB, OK) physicaldrive 1I:0:3 (port 1I:box 0:bay 3, SATA HDD, 4 TB, OK) physicaldrive 1I:0:4 (port 1I:box 0:bay 4, SATA HDD, 8 TB, OK) physicaldrive 2I:0:5 (port 2I:box 0:bay 5, SATA HDD, 4 TB, OK) physicaldrive 2I:0:6 (port 2I:box 0:bay 6, SATA HDD, 4 TB, OK) physicaldrive 2I:0:7 (port 2I:box 0:bay 7, SATA HDD, 4 TB, OK) physicaldrive 2I:0:8 (port 2I:box 0:bay 8, SATA HDD, 4 TB, OK) I'd expect the rebuild to start automatically after 1I:0:4 was replaced. Is the new drive being larger than the old one (4-->8) causing issues?

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.

Enjoy the fresh new release! -- Pablo Greco ------------------------------ Message: 2 Date: Thu, 12 Nov 2020 06:41:38 -0600 From: Johnny Hughes <johnny(a)centos.org> To: CentOS-Announce <centos-announce(a)centos.org> Subject: [CentOS-announce] Release for CentOS Linux 7 (2009) on the x86_64 Architecture Message-ID: <2a5ce9c6-5e2c-2aa7-f2c8-afb508a1ec65(a)centos.org> Content-Type: text/plain; charset="utf-8" Release for CentOS Linux 7 (2009) on the x86_64 Architecture We are pleased to announce the general availability of CentOS Linux 7 (2009) for the x86_64 architecture. Effectively immediately, this is the current release for CentOS Linux 7 and is tagged as 2009, derived from Red Hat Enterprise Linux 7.9 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: e33d7b1ea7a9e2f38c8f693215dd85254c3a4fe446f93f563279715b68d07987 CentOS-7-x86_64-DVD-2009.iso 689531cce9cf484378481ae762fae362791a9be078fda10e4f6977bf8fa71350 CentOS-7-x86_64-Everything-2009.iso 07b94e6b1a0b0260b94c83d6bb76b26bf7a310dc78d7a9c7432809fb9bc6194a CentOS-7-x86_64-Minimal-2009.iso b79079ad71cc3c5ceb3561fff348a1b67ee37f71f4cddfec09480d4589c191d6 ?

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

centos8 / anaconda EFI regression / HFS+ ESP
by Leon Fauster 12 Nov '20

12 Nov '20

Hi folks, years ago I had no problem installing CentOS7 on my iMac workstation (iMac Late 2015). The installation worked out of the box. Today I wanted to upgrade to CentOS8 and while configuring the partitions I get an error that the installation can not start because: "HFS+ ESP needed and mounted on /boot/efi". In fact they are the same partition as for CentOS7. Is this a regression of anaconda, implying that the EFI partition must be HFS based? I can boot CentOS7 with the vfat EFI partition ... -- Leon

BIOS RAID0 and differences between disks
by H 12 Nov '20

12 Nov '20

My computer running CentOS 7 is configured to use BIOS RAID0 and has two identical SSDs which are also encrypted. I had a crash the other day and due to a bug in the operating system update, I am unable to boot the system in RAID mode since dracut does not recognize the disks in grub. After modifying the grub command line I am able to boot the system from one of the harddisks after entering the LUKS password, seemingly without any problems but am obviously not running in RAID0 mode. When I booted in single-disk mode I am sure there were some new files created on the single SSD the system sees but I fairly quickly shut it down until this can be fixed. My question is: once the operating system fix has been released and I can once again boot in BIOS RAID0 mode and decrypting both SSDs (same password entered only once of course), how will the BIOS RAID0 react? How will it handle new files on one disk, altered timestamps etc.? Thanks.

systemd / services / current process list
by Leon Fauster 08 Nov '20

08 Nov '20

Hi, following requirement is needed here (forced by application migration from C6->C8): I have two services running under supervision by systemd. ServiceA: runs as user AppUser ServiceB: runs as user AppUser ServiceB can see "all" processes from AppUser (ps aux) running by systemd (in fact it sees no other processes). So ServiceB can see the processes of ServiceA. I have also a cron job that runs every 5 minutes as user AppUser. Now the problem is, that ServiceB via ps aux can't see the process of the cron job albeit running by the same AppUser. Which security feature of systemd can be altered to allow seeing all or at least AppUser's processes? ServiceA as only this "features": PrivateTmp=true ServiceB as only this features: PrivateTmp=true RuntimeDirectory=calculation RuntimeDirectoryMode=0755 Any hints would be great! Thanks, Leon

LibreOffice locking up
by H 07 Nov '20

07 Nov '20

I am running LibreOffice 5.3.6.1 under the latest update of CentOS 7 and the Mate desktop. Not infrequently LibreOffice Calc locks up and I have to force close the application. Altough the spreadsheet is rather large I would not consider it complex. This has been going on for some time and I am curious if the bug might be in LibreOffice or if there is some interaction with the Mate desktop that might be responsible. Both CentOS, LibreOffice and Mate have been regularly updated from the standard repositories for a long time. Does anyone else have the same problem?

Centos 8 and xfs_quota
by david 06 Nov '20

06 Nov '20

Folks I'm trying to use xfs_quota to keep track of disk space usage for my users. The documentation states that I should specify "uquota" as an option on the mount data in /etc/fstab. Yet, I cannot find the entry in fstab that corresponds to the Logical Volume that ends up being mounted on /home1. The system in question was installed on a single disk system. Later, after install, I added a second disk, created a Logical Volume on it, and mounted it as /home1, where all the user data gets stored. It holds an xfs file system. Upon examining /etc/fstab, there's no evidence of the second disk, yet it does get mounted: [root@ape ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri May 1 21:05:38 2020 # # Accessible filesystems, by reference, are maintained under '/dev/disk/'. # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # # After editing this file, run 'systemctl daemon-reload' to update systemd # units generated from this file. # /dev/mapper/cl_ape-root / xfs defaults 0 0 UUID=d5a206d6-7ea1-42b7-8f52-071e98d09f98 /boot ext4 defaults 1 2 /dev/mapper/cl_ape-swap swap swap defaults 0 0 [root@ape ~]# Yet, when I look at the current mounts of xfs file systems: [root@ape ~]# mount | grep xfs /dev/mapper/cl_ape-root on / type xfs (rw,relatime,attr2,inode64,noquota) /dev/mapper/vg_abcde-lv01 on /home1 type xfs (rw,relatime,attr2,inode64,noquota) [root@ape ~]# the LV of the second disk shows up. lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 25G 0 disk +-sda1 8:1 0 1G 0 part /boot +-sda2 8:2 0 24G 0 part +-cl_ape-root 253:0 0 21.5G 0 lvm / +-cl_ape-swap 253:1 0 2.5G 0 lvm [SWAP] sdb 8:16 0 5.2T 0 disk +-vg_abcde-lv01 253:2 0 5.2T 0 lvm /home1 sr0 11:0 1 597M 0 rom [root@ape ~]# How do I enable quotas on a file system that is being mounted but not in fstab? I suspect systemd has a role here, but I can't find any evidence. David

GVIM annoyances
by Gary Stainburn 06 Nov '20

06 Nov '20

I've just upgraded from my old F9 box to C7, which of course means lots of changes. However, the ones are are annoying me most are with VIM. No matter what I do I can't get gvim to open in a reasonable size. I have a dual headed setup (laptop + external) and every time gvim opens it takes up both screens. I've tried a few suggestions including the one below without success. In fact this one causes X to crash when I start gvim. The second problem I have is the selection of the font. My old box had "sans Regular 12" which was a lovely font to work with. However, when I choose the same font on the new box it's hideous. I don't know best how to request this, but basically how can I have my nice old font back? |if has("gui_running") " GUI is running or is about to start. " Maximize gvim window. set lines=999 columns=999 else " This is console Vim. if exists("+lines") set lines=50 endif if exists("+columns") set columns=100 endif endif |

Style Guide for ASCII Text Documents ?
by Nicolas Kovacs 06 Nov '20

06 Nov '20

Hi, Can anyone on this list recommend a good style guide for formatting technical documentation (HOWTOs related to CentOS servers) using ASCII text only ? Markdown and/or AsciiDOC are *not* an option, since these documents should be easily readable in a text console.

enp0s25 disconnect
by Michael Hennebry 04 Nov '20

04 Nov '20

I tried to boot a Centos 8.2 install CD, one burned with Centos-8-2-2004-x86_64-boot . In the setup, it persisted in telling me that ethernet thing enp0s25 was disconnected. Nyet. 'Twas working several seconds previous and is working now. This is a showstopper. How do I debug it? Also, whatever else it did, I now have environment variable HOSTNAME=2001-48F8-3004-2CE-1AE9-F1BF-8759-FF4C-dynamic.midco.net . It shows up on my terminal window headers and as part of the prompt on one terminal.

dnsmasq centos 7
by Jerry Geis 03 Nov '20

03 Nov '20

HI I setup dnsmasq on my computer. I tested with an entry in /etc/hosts for laptop.w530 I tested with "host laptop.w530" and I get unresolved (expected). If I add "nameserver 192.168.1.8" (my computer) to top of /etc/resolv.conf and do "host laptop.w530" I get 192.168.1.105 - so seems to be working. Then I goto another machine, add the "nameserver 192.168.1.8" to /etc/resolv.conf and do the same "host laptop.w530" and it does not resolve. I can "telnet 192.168.1.8 53" to my machine and I get a response. Am I missing something to have "other" machines ask my machine for name resolution ? Thanks, Jerry

ThinkStation with BIOS RAID and disk error messages in gparted
by H 03 Nov '20

03 Nov '20

My ThinkStation runs CentOS 7 which I installed on a BIOS RAID 0 setup with two identical 256 Gb SSDs after removing Windows. It runs fine but I just discovered in gparted something that does not seem right: - Launching gparted it complains "invalid argument during seek for red on /dev/md126" and when I click on Ignore I get another error "The backup GPT table is corrupt, but the primary appears OK, so that will be used." I then click on OK whereupon I again see the second error message. I then see "Not all of the space available to /dev/sdb appears to be used, you can fix the GPT to use all of the space (an extra 6832 blocks) or continue with the current setting? " I click on Fix but nothing seems to happen. I am not sure what /dev/md126 is but it is the exact same size as sda and sdb which I believe are the two RAID disks. I also have two other hard disks which seem to be fine, one using XFS, the other ZFS. Does this look familiar to anyone? Given the error messages it seems this is something I ought to fix sooner rather than later. Any idea what I should do? Thanks.
