ls permissions format changed in CentOS 8
by Kenneth Porter 26 Oct '19

26 Oct '19

When I use "ls -al" on a directory, for files with only owner read/write permission, the displayed attributes are "-rw-", not "-rw-------". That means the file names don't line up with other files in the directory, which makes the listing harder to read. What changed where and how do I fix that?

Have "system"/Hunspell dictionaries stopped working in CentOS 7 Firefox?
by Toralf Lund 25 Oct '19

25 Oct '19

Until quite recently, multiple spell-checker languages were available in Firefox on my CentOS 7 system. (They could be selected from "Languages" under the right-click menu in text boxes.) After a recent system upgrade, there is only "English (United States)". I don't think I had installed any extra Firefox dictionaries as such, but the "global" spell-checking support is set up to support a few extra languages via hunspell-<lang> software packages. I believe Firefox used to be able to pick these up - probably through a link from /usr/lib64/firefox to /usr/share/myspell that the CentOS firefox package provides. Did I get that right? Has the mechanism stopped working? Is there any way to re-enable the system dictionaries? Note that I get all the expected dictionaries in Thunderbird, which appears to rely on a similar hack. My Firefox is "firefox-68.1.0-2.el7.centos.x86_64". Thanks. - Toralf

smart card auth
by Stephen Berg (Code 7309) 25 Oct '19

25 Oct '19

I updated my work desktop to kernel-3.10.0-1062.4.1.el7.x86_64 yesterday as I was leaving. This morning booted into that new kernel I was unable to login using my common access card. Rebooted in the previous kernel (3.10.0-1062.1.2.el7.x86_64) and smart card login works fine. Anyone else seeing any similar problems? I haven't had time to dig deeply into the logs yet but I did a bunch of pcscd restarts overnight, about once per hour according to monit. -- Stephen Berg, IT Specialist, Ocean Sciences Division, Code 7309 Naval Research Laboratory W: (228) 688-5738 <- (Preferred contact) DSN: (312) 823-5738 C: (228) 365-01

UEFI and PXE
by isdtor 25 Oct '19

25 Oct '19

We have a working PXE setup. I've tried to adapt it to UEFI as per RHEL6 manual, but the client won't boot. Strangely, tcpdump shows that the client tries to download all files via tftp from the dhcp server rather than the tftp server (they are different). next-server is pointing to the tftp server. Any clues?

fresh C7.7 install
by Jerry Geis 25 Oct '19

25 Oct '19

HI all, I just did a fresh C7 install using kickstart. fdisk -l /dev/sda shows: # Start End Size Type Name 1 2048 2050047 1000M EFI System EFI System Partition 2 2050048 104450047 48.8G Microsoft basic 3 104450048 112642047 3.9G Linux swap 4 112642048 234440703 58.1G Microsoft basic What extra do I need to specify in my kickstart so that the "type" above is not Microsoft basic? For example, currently a line in my kickstart would be: part /home --ondisk=/dev/sda --fstype ext4 --size=58G --asprimary What is missing so the type is set correctly to linux root or linux home? Thanks, Jerry

Putting together a system build, AMD based. Ryzen 5 CPU on X570 chipset with Radeon RX480 GPU. Guessing this will be supported by Centos OK?

I will give this a try as this only on an experimental machine and it will be rebuilt when 8.1 comes out, and hopefully epel will be updated by then. -- Cheers Bill

Difference between "CentOS Linux 8" and "RHEL8"
by Sergio Belkin 25 Oct '19

25 Oct '19

Hi, I've read about all recent changes about workflow: Fedora>CentOS Stream. I understood that in the end CentOS Linux (8) keeps on being "built from publicly available open source source code provided by Red Hat, Inc for Red Hat Enterprise Linux"[1] Is that correct? I mean the only that changed are CentOS upstream (Fedora and Centos Stream) didn't it?

Conky on CentOS 8
by Bill Maidment 24 Oct '19

24 Oct '19

Hi I've been using conky in conjunction with gcalcli on Scientific Linux 7 to display google calendar data on screen. In CentOS 8, I have set up the gcalcli part, but I can't find a conky rpm. Is anyone working on creating this for CentOS 8? There appears to be an rpm for fedora 28 onwards, but there are dependency issues. Can anyone help? -- Cheers Bill

CentOS 8: what changed (regular UNIX admin commands)?
by Valeri Galtsev 24 Oct '19

24 Oct '19

Hello Experts! I'm sure many of you run CentOS for some time already. My question is: is there some place that lists which of the most often used sysadmin commands are gone and what are replacements for them. Or what else one needs to do after successful installation. (in the past it was process accounting that was not enabled by default, but which gives you quite some handle in investigating compromise). I just tried quite ordinaly command of freshly installed CentOS 8: last and got an error: last: (default utx db): No such file or directory I realize that it could be just me, and I'll cope with that myself one way or another but this one prompted me to ask everybody: Is there anything I can read so I can learn what differenmt to expect on CentOS 8 from, say, CentOS 7? Thanks.

rsync: did not see server greeting.
by Ralf Prengel 24 Oct '19

24 Oct '19

Hallo, until last week I used a debian system for syncing debian and centos mirrors. Everything worked fine for years. After installing centos 7 rsync doesn t work any longer. The configuration of the firewall is the same as before. The message I see is rsync: did not see server greeting. Has anyone a hint for me? Are ther any main differences between rsync debian and rsync centos? Thanks Ralf

moving from centos 8 to stream? (and possibly back again?)
by Robert P. J. Day 23 Oct '19

23 Oct '19

just installed stock centos 8 x86_64 and did "dnf update", now reading up on centos stream, and wondering: 1) can i, at any time, decide to convert this system to centos stream, notwithstanding any normal updates i've done in the meantime? 2) if i'm running centos stream and decide it's just too progressive for me, can i dial it back to "regular" centos down the road? rday -- ======================================================================== Robert P.

Centos 8 hardware compatibility testing?
by Frank Cox 23 Oct '19

23 Oct '19

With Centos 7 and earlier I've been using the Live CD image to test new hardware (laptops etc) for compatibility. That way I can get a desktop up and try the sound and the networking and whatnot without affecting what is already installed on the machine, and then if everything looks good I can just run the installer right from the Live CD image. There's no Live CD image for Centos 8, so what would be a good way to accomplish the task of testing new hardware with Centos 8 before attempting to install the operating system? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Stream not installing centos-release-stream
by Rich Greenwood 22 Oct '19

22 Oct '19

It looks like anaconda isn't installing centos-release-stream when you install CentOS 8 Stream. I just did a minimal install through PXE and it pulled everything from the 8-stream repository and installed the stream versions, but didn't install centos-release-stream. (Below is the output of yum list \*release\* immediately after install.) This means that it will not get updates from stream. Is this intentional or is this a bug? --Rich Last metadata expiration check: 0:06:02 ago on Tue 22 Oct 2019 11:02:55 AM PDT.

C8 regression / tmp on tmpfs
by Leon Fauster 22 Oct '19

22 Oct '19

Does someone have a working tmp on tmpfs via systemctl enable tmp.mount under CentOS8/RHEL8? This seems to work straight in EL7 ... # LANG=C systemctl enable tmp.mount The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...). 4) In case of template units, the unit is meant to be enabled with some instance name specified. -- Leon

Migrating users to new server
by Kenneth Porter 22 Oct '19

22 Oct '19

An age-old problem and there are some simple awk/grep-based scripts to handle the easy cases. Are there any more sophisticated tools that can extract all non-system users and groups and then merge the result into the password/group/shadow/gshadow files of a new server? I don't need home directories or mbox inboxes created because I'll rsync those over once I've created the users. Tricky problems include merging entries for existing users and groups, and renumbering if one is moving from a 500-based system to a 1000-based system. (I did the latter long ago so don't need it this time.) Red Hat's page with some simple commands to handle the easy cases: <https://access.redhat.com/solutions/179753>

Failure to install boot loader on Dell PowerEdge R720xd
by Kenneth Porter 21 Oct '19

21 Oct '19

What command does the installer use to install the boot loader? I sucessfully installed CentOS 8 to the server, with /usr on a mirrored SSD pair on the RAID controller and /boot on the internal SD card (where Dell wants one to boot from). Before rebooting, I inspected the installation at /mnt/sysimage and the disk usage looked reasonable. I saw a grub directory in /boot but no second stage boot loader nor any config files for it. At the end of the process, I got an error message that the installer failed to install the boot loader and the resulting system wouldn't boot. It didn't. There were no details useful for diagnosis. So now I'm about to boot the installer DVD into rescue mode to manually install the boot loader and see the real error message. So what command do I issue?

Hallo, I try to use my own repo. The problem: The repo is working when using it while installing a fresh system using pxe and kickstart. When changing the content and rebuilding the repo new packages are not found. My question: What is the right way to reinit a repo complete? I tried several hints I found in the web but new packages are never found. Thanks Ralf Von meinem iPad gesendet

Manual partitioning and LVM
by Kenneth Porter 21 Oct '19

21 Oct '19

I can't seem to figure out how to partition for install. I've tried both CentOS 8 and 7.7 netinstalls. I've got 3 disks: sda (big hardware RAID array), sdb (SSD), and sdc (internal SD card for booting). I want to put /boot on sdc, /usr on sdb, and / on sda. I don't care what format is used on sdb and sdc, whatever will let it boot. I want LVM on sda so that I can use snapshotting for backups. I can pre-format sdb1 and sdc1 as ext4 usinga gparted live DVD. If I select manual partitioning, I can then label and assign those two to /usr and /boot. I can see sda in the drives available on the first detination screen but but I don't see it in the manual partitioning screen. So I don't see how to partition and format it as an LVM volume that I can mount to /.

Custom LiveCD images with CentOS8

CentOS 8 Docker container is missing dnf-plugin-ovl
by Richard Berger 19 Oct '19

19 Oct '19

Hi everyone, I've been running some tests on Travis CI with CentOS 7 and CentOS 8 based Docker containers and having issues with the CentOS 8 ones. With the centos:8 image, the RPM database eventually gets corrupted due to the default overlay2 storage driver used by Docker. This issue doesn't show with the centos:7 container. It already comes with the "fastestmirror" and "ovl" plugins installed. The "ovl" plugin is a workaround to avoid this corruption. See the bottom of https://docs.docker.com/storage/storagedriver/overlayfs-driver/ for more details. Fedora 29 and 30 already have an equivalent "dnf-plugin-ovl" package ( https://src.fedoraproject.org/rpms/dnf-plugin-ovl) However, I couldn't find it for RHEL8 or CentOS 8. I can use the "touch" workaround for now. But are there plans to bring this plugin to CentOS 8 and make it part of the CentOS 8 image, just like on CentOS 7? Or is there some other way to achieve the same with dnf? Thanks in advance, Richard -- Dr. Richard Berger richard.berger(a)temple.edu Office: SERC 716 Research Associate Professor, Dept. of Chemistry, College of Science and Technology Temple University, Philadelphia PA 19122

What is /etc/subuid ?
by Valeri Galtsev 18 Oct '19

18 Oct '19

Dear Experts, Could someone enlighten me about the following file: /etc/subuid ? This file appears to be owned by "setup" package. This is CentOS 7 system, and until now these files if existed were never changed. Today I have added user quite routine way, by doing /usr/sbin/groupadd -g 4500 [username] /usr/sbin/useradd -g [username] -u 4500 -c "User Name, email@domain" [username] And the file /etc/subuid changed and user was added into it: [username]:100000:65536 Nothing like that was happening before. This is first time I create account after update done on Oct 3, 2019. I checked several CentOS 7 machines, basically doing this: # grep subuid /usr/sbin/useradd Binary file /usr/sbin/useradd matches And CentOS 7 machines indeed may have that file name in the useradd binary. None of CentOS 6 machines has that. I tried to do FreeBSD-ism: man /etc/subuid came empty, and realized that I'm doing FreeBSD-ism. I tried to do search on the web (did not "google", I use duckduckgo... so I "did search"), and came pretty much empty. Is it just me, or indeed something in CentOS 7 indeed changed? And what is it? Another question on the same note: how do we find out what the file is about and is used for in Linux, apart from searching on the web. (When there are surprises like the one I had today, one does like to know what this particular file is used for). Thanks in advance for your answers.

Hiding a grub menuentry?
by James Pearson 18 Oct '19

18 Oct '19

Does anyone know if it is possible to 'hide' a grub menuentry with CentOS 7 ? I have a custom menuentry that I don't want to be seen on the grub screen - but it needs to be selectable as the entry to boot via 'grub2-reboot' I've scanned the grub2 documentation - but I can't find anything obvious - so I'm guessing it can't be done - unless someone knows otherwise ?

DSA key not accepted on CentOS even after enabling
by Gianluca Cecchi 18 Oct '19

18 Oct '19

Hello, I have some users that connect to a server with their DSA key that is of type ssh-dss. I'm migrating (installing as new) the server where they connect to CentOS 8 + updates. I was not able to connect with the keys to this new server even after having added, as found in several internet pages, this directive at the end of /etc/ssh/sshd_config of the CentOS 8 server: # Accept also DSA keys PubkeyAcceptedKeyTypes=+ssh-dss and systemctl restart sshd I kept getting in journal the message: userauth_pubkey: key type ssh-dss not in PubkeyAcceptedKeyTypes [preauth] I saw that the sshd process had started with the option ... -oPubkeyAcceptedKeyTypes=rsa-sha2-256,ecdsa-sha2-nistp256, ecdsa-sha2-nistp256-cert-v01(a)openssh.com,ecdsa-sha2-nistp384, ecdsa-sha2-nistp384-cert-v01(a)openssh.com,rsa-sha2-512,ecdsa-sha2-nistp521, ecdsa-sha2-nistp521-cert-v01(a)openssh.com,ssh-ed25519, ssh-ed25519-cert-v01@openssh.com,ssh-rsa,ssh-rsa-cert-v01@openssh.com So I found the unit file for sshd that refers to /etc/crypto-policies/back-ends/opensshserver.config In the mean time I was able to reach my target going and editing the /etc/sysconfig/sshd file adding the whole line obtained from the above and adding ssh-dss CRYPTO_POLICY='-oCiphers=aes256-gcm(a)openssh.com, chacha20-poly1305@openssh.com,aes256-ctr,aes256-cbc,aes128-gcm@openssh.com,aes128-ctr,aes128-cbc -oMACs=hmac-sha2-256-etm@openssh.com,hmac-sha1-etm@openssh.com, umac-128-etm@openssh.com,hmac-sha2-512-etm@openssh.com ,hmac-sha2-256,hmac-sha1,umac-128(a)openssh.com,hmac-sha2-512 -oGSSAPIKexAlgorithms=gss-gex-sha1-,gss-group14-sha1- -oKexAlgorithms= curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1 -oHostKeyAlgorithms=rsa-sha2-256,ecdsa-sha2-nistp256, ecdsa-sha2-nistp256-cert-v01(a)openssh.com,ecdsa-sha2-nistp384, ecdsa-sha2-nistp384-cert-v01(a)openssh.com,rsa-sha2-512,ecdsa-sha2-nistp521, ecdsa-sha2-nistp521-cert-v01(a)openssh.com,ssh-ed25519, ssh-ed25519-cert-v01@openssh.com,ssh-rsa,ssh-rsa-cert-v01@openssh.com -oPubkeyAcceptedKeyTypes=rsa-sha2-256,ecdsa-sha2-nistp256, ecdsa-sha2-nistp256-cert-v01(a)openssh.com,ecdsa-sha2-nistp384, ecdsa-sha2-nistp384-cert-v01(a)openssh.com,rsa-sha2-512,ecdsa-sha2-nistp521, ecdsa-sha2-nistp521-cert-v01(a)openssh.com,ssh-ed25519, ssh-ed25519-cert-v01@openssh.com,ssh-rsa,ssh-rsa-cert-v01@openssh.com ,ssh-dss' and now it works with pubkey authentication based on DSA keys. Not going to the querelle of OpenSSH 7 removing DSA keys and DSA vs RSA (eg. some considerations by some years ago here: https://security.stackexchange.com/questions/5096/rsa-vs-dsa-for-ssh-authen… ), any hint on smarter way to add? I suppose further updates could change content of /etc/crypto-policies/back-ends/opensshserver.config that btw is part of crypto-policies-20181217-6.git9a35207.el8.noarch and not openssh-server-7.8p1-4.el8.x86_64 HIH others incurring in this problem and thanks in advance for any insight/hint, Gianluca

easy way to stop old ssl's
by Jerry Geis 16 Oct '19

16 Oct '19

HI all, When CentOS 7 was created things like SSLv2 TLSv1 TLSv1.1 etc... were all OK, but now they have fallen out of favor for various reasons. Updating to CentOS 7.7 does not automatically disable these types of items from apache - is there a script that is available that can be ran to bring a box up to current "accepted" levels ? Or is that an edit by hand, do it yourself on all your boxes or create your own script type of thing. Just checking if there is an easier way. Thanks, Jerry

Odd issue with 7.7.1908 updated with qemu-kvm-ev
by Lamar Owen 15 Oct '19

15 Oct '19

So, I have a client that has an internal use application that needs an ancient version of libc5. That's not a typo; libc5. Before the server that ran it died about a year and a half ago (said server was an AMD K6-2/450 with a 6GB Western Digital Caviar drive that had been spinning nearly continuously for almost 20 years!) it was running on Red Hat Linux 5.2. The last version of CentOS that shipped with a libc5 was 2.1. So I set them up a KVM guest running CentOS 2.1, mainly because Red Hat 5.2 wouldn't recognize the network at all, using the e1000 network driver, and it ran well. Now, yes, there are no updates, but no it doesn't matter; it's an internal use application that has a very small footprint and very low risk. After the update on the host to 7.7.1908, the network stopped running. The host also has a CentOS 7 guest that is still working properly. If I change the 2.1 system to not automatically load the e1000 driver and console in and 'modprobe e1000' manually, it starts working again, for a while. Any ideas as to where to start looking? qemu-kvm-ev itself, or libvirt? I'm planning to start out with rollbacks to the previous versions of each to try to find where the issue starts.

CVE-2019-6470 - dhcpd6 bug in CentOS 8 not being fixed?
by Steinar Skjelanger 14 Oct '19

14 Oct '19

The CVE-2019-6470 bug in isc-dhcp for ipv6 causing the server to crash on a regular basis is marked as "will not fix" for RHEL 8 on Red Hat's web site [1]. It's already got a fix for RHEL/CentOS 7, and other distros (like Ubuntu and Fedora) have released fixes. Is anyone familiar with the issue, or know about a (reasonable) workaround? Or why Red Hat doesn't want to fix it? I tried to contact Red Hat support to get their reasoning, but as we only have self-support subscriptions with them, they were not particulary interested in talking to me.

CentOS 8 virt-manager
by Tom Bishop 13 Oct '19

I am thinking about building a new host and trying to decide if virt-manager is working on CentOS 8. I thought I saw previously on the mail list that there were some issues but cannot find the thread right now. If anyone has migrated some workloads from 7 and seen any issues let me know. Thanks :)

Is it a way to upgrade CentOS 7 to 8?
by Pierre Malard 13 Oct '19

Hi, I’m looking for a method to upgrade my centos 7 servers to 8 and I don’t find anything to do that! I’m a very newbie with CentOS? My choices where gone to Debian or Ubuntu and it was very simple. Just some files must be changed (/etc/apt/source.list). My search suggest a RELH subscription. Is it the only way?

C8 and KDE
by Alessandro Baggi 12 Oct '19

Goog morning to the list, for all users that are interested about KDE Plasma on Centos 8 you can install KDE from epel. All packages are get from epel-playground and epel-testing and some packages seems need to be build. I run "yum grouplist" and see kde workspace available. I tried to install it, reboot my machine and running startx a KDE plasma session was correctly launched. I think that this is a testing release and not ready for production but if you want play you can try. Maybe you will find bug and can help EPEL to fix. Best regards.
