Chromium 85 does not load any pages
by H 24 Sep '20

24 Sep '20

I just upgraded chromium on my CentOS 7 system and ended up with nothing loading. I tried to downgrade using yum downgrade chromium but there does not seem to be an older version on my system, nor does EPEL seem to have version 84 which is what I ran before. First, does anyone know why chromium 85 does not load /anything/? Firefox runs fine. Second, why is chromium 84 not available in EPEL? Thanks.

ZFS and encryption on CentOS 7
by H 23 Sep '20

23 Sep '20

Can I ask what the prevailing opinion is on ZFS and encryption on CentOS 7? Is encryption in ZFS stable? If so, I would use it on a new naked drive I just added. If not, I might stick with LUKS and XFS for now. The drive is a 2 Tb SSD. Thanks.

Forefox on C7 - uses wrong program to view download folder
by Gary Stainburn 23 Sep '20

23 Sep '20

I've got a C7 laptop using the default repo's (installed plus epel). My firefox has decided to use the wrong program to view the downloads folder. If I download and save a file, then click on the Downloads icon and click on view folder containing the file, it opens the MP3 editor EasyTag instead of Dolphin or Konquror. How do I change it back.

iptables & voip
by Gregory P. Ennis 22 Sep '20

22 Sep '20

Everyone, I would like to use our gateway linux machine to give bandwidth preference to voip udp packets. Can anyone point me to a tutorial about the use of voip and iptables? I usually prefer to use iptables instead of firewalld. iptables is more intuitive, and easier to understand. Thanks much!!! Greg Ennis

CentOS Linux updates released (RSS Feeds)
by Johnny Hughes 21 Sep '20

21 Sep '20

As you may or may not know, we do not have the ability to currently announce CentOS Linux 8 announcements on the CentOS Annonuce Mailing List. We would like to add this in the future. For now, what we do have is an RSS feed for all updates that get released. Use your favorite RSS Feed Tool (I use Thunderbird .. lots of other things available). https://feeds.centos.org/ Subscribe to the xml file you are interested in .. for example, for normal CentOS Linux 8 x86_64 arch installs .. you would subscribe to: https://feeds.centos.org/centos-8-x86_64-BaseOS.xml https://feeds.centos.org/centos-8-x86_64-AppStream.xml This is for people who have asked about what rpms are updated and how to see when new updates happen on CentOS Linux 8. But it works for all versions of CentOS (There are xml files for all repos of CentOS Linxui 6. 7, and 8 .. Also CentOS Stream). Thanks, Johnny Hughes

CentOS 8 LSI SAS2004 Driver
by William Markuske 20 Sep '20

20 Sep '20

Hello, I've recently been given domain over a number of supermicro storage servers using Broadcom / LSI SAS2004 PCI-Express Fusion-MPT SAS-2 [Spitfire] (rev 03) to run a bunch of SSDs. I was attempting to do fresh installs of CentOS 8 and have come to find out that RedHat deprecated support for a number of HBAs for 8 including all running the SAS2004 chip. Does anyone know if there is a driver available for this chip from a third party repo? My google searches have led me to believe that EPEL 8 has a kmod-mpt3sas package but it does not seem to exist though multiple blogs have stated otherwise. If anyone knows if there is a solution for CentOS 8 that would be great or if I have to roll back to CentOS 7 for card support. Thanks, William

Drive failed in 4-drive md RAID 10

I got the email that a drive in my 4-drive RAID10 setup failed. What are my options? Drives are WD1000FYPS (Western Digital 1 TB 3.5" SATA). mdadm.conf: # mdadm.conf written out by anaconda MAILADDR root AUTO +imsm +1.x -all ARRAY /dev/md/root level=raid10 num-devices=4 UUID=942f512e:2db8dc6c:71667abc:daf408c3 /proc/mdstat: Personalities : [raid10] md127 : active raid10 sdf1[2](F) sdg1[3] sde1[1] sdd1[0] 1949480960 blocks super 1.2 512K chunks 2 near-copies [4/3] [UU_U] bitmap: 15/15 pages [60KB], 65536KB chunk smartctl reports this for sdf: 197 Current_Pending_Sector 0x0012 200 200 000 Old_age Always - 1 198 Offline_Uncorrectable 0x0010 200 200 000 Old_age Offline - 6 So it's got 6 bad blocks, 1 pending for remapping. Can I clear the error and rebuild? (It's not clear what commands would do that.) Or should I buy a replacement drive? I'm considering a WDS100T1R0A (2.5" 1TB red drive), which Amazon has for $135, plus the 3.5" adapter. The system serves primarily as a home mail server (it fetchmails from an outside VPS serving as my domain's MX) and archival file server.

storage for mailserver
by Michael Schumacher 20 Sep '20

20 Sep '20

hi, I am planning to replace my old CentOS 6 mail server soon. Most details are quite obvious and do not need to be changed, but the old system was running on spinning discs and this is certainly not the best option for todays mail servers. With spinning discs, HW-RAID6 was the way to go to increase reliability and speed. Today, I get the feeling, that traditional RAID is not the best option for SSDs. I am reading that all RAID members in SSD-arrays age synchronously so that the risk of a massive failure of more than one disk is more likely than with HDDs. There are many other concerns like excessive write load compared to non-raid systems, etc. Is there any common sense what disk layout should be used these days? I have been looking for some kind of master-slave system, where the (one or many) SSD is taking all writes and reads, but the slave HDD runs in parallel as a backup system like in a RAID1 system. Is there any such system? Any thoughts? best regards Michael Schumacher

Be sure it's the drive you want to find then put dd if=/dev/sdf of=/dev/null into a shell, but don't run it. Look at the drives and hit enter and watch for which one lights up. Then ^c while watching to be sure the light turns off exactly when you hit it.

erasing a disk
by david 15 Sep '20

15 Sep '20

Folks I've encountered situations where I want to reuse a hard-drive. I do not want to preserve anything on the drive, and I'm not concerned about 'securely erasing' old content. I just want to be able to define it as an Physical Volume (in a logical volume set), or make it a ZFS disk, or sometimes make it a simple EXT3, ExFAT or NTFS disk. However, old 'signatures' get in the way and Linux sometimes refuses to let me proceed. I know that a fool-proof solution is to use the "dd if=/dev/zero bs=32768 oflag=direct" on the disk, but when we're talking USB-connected hard drives of 8 TB, that's an operation that can take days. The disk in question might even have been corrupted. This would make using 'zpool destroy' to clear out a ZFS disk, or I've tried erasing the first megabyte of the disk, but there are ZFS or LVM structures that get in the way. So, does anyone have an efficient way to erase structures from a disk such that it can be reused? Something like -erase first N blocks (block defined as 4096) - Erase <number> blocks starting at block <number> - erase last <number> blocks At least such an algorithm would be quicker than erasing 8 TB of data.

Server entering Emergency Shell, but continues fine after pressing Enter
by Quinn Comendant 12 Sep '20

12 Sep '20

Hello all, I've got an odd problem that doesn't seem to be mentioned anywhere. I have several identical CentOS 7 servers (GCE instances). I recently ran `yum update` and rebooted all of them. All the servers came back fine except one. I opened a connection to the serial console of the broken server, and was greeted with this prompt: … Cannot open access to console, the root account is locked. See sulogin(8) man page for more details. Press Enter to continue. I pressed Enter, and the boot process continued successfully! Just to test, I restarted the server again, and the same thing happened: I had to manually log in to the console and press Enter before it would complete the boot process. No other step was required. I also tried creating a snapshot of the disk, and booted a new VM with a boot disk imaged from the snapshot. The same problem occurred, pressing Enter was all that was required. Earlier in the boot log, it shows "Started Emergency Shell", which is why there was a "Press Enter" prompt. The error that the "root account is locked" isn't the issue; the root account is locked on all our servers. So, in summary: something is causing the server to enter an Emergency Shell, but continues successfully after pressing Enter. That's odd because if Emergency Shell is loaded, usually something more serious is happening and requires more actions to get the server to boot. Anybody have any idea what could be causing this? I don't see any significant errors in the boot log, but I would appreciate if anyone has a moment to help me look for issues. Here's a copy of the serial console boot log – you can find the "Press Enter to continue" on line 536: https://write.as/dwuts24dcw6yh0kf.txt Thanks! Quinn

Thunderbird won't start after move to new box
by Gary Stainburn 12 Sep '20

12 Sep '20

I've tried moving my Thunderbird profile from one C7 box, a standard PC to another C7 box, a DELL server. I did this by rsync'ing ~/.thunderbird. However, on the new box, Thunderbird only starts if I run it -safe-mode. If I don't run it in safe mode I see the window flash up and instantly close. No errors or notifications appear in the terminal window., Anyone got suggestions on what could be wrong, or how I can diagnose it? Google just seems to bring up hits for problems on Windows boxes.

Hi list, I'm running CentOS 8.2 with Plasma from EPEL and I noticed that I have problem using numeric keypad of my keyboard when using plasma application like Konsole, Kcalc, Konqueror and all application of Plasma. Using Firefox, Thunderbird, xterm, Libreoffice all works as expected. So this problem is related to Plasma application. I noticed the same problem on sddm login. I noticed that to make the numeric keypad to work I need to press SHIFT+NUMKEY. I tried to manage Plasma keyboard configuration but nothing worked. I tried my keyboard on other PC and distro but the problem does not occour. I should try this using GNOME or XFCE but being a KDE user I would avoid to install the others. There is a way to solve this problem? Thank you in advance. Alessandro.

Conversion from Centos 5 to Centos 7 & mailx changes
by Gregory P. Ennis 07 Sep '20

07 Sep '20

Everyone, I have just upgraded a Centos 5 server to a Centos 7 server and am having difficulty with a change of behavior of mailx with the use of a command line of : mail -s 'This is the subject' user(a)domain.com < text_file.txt On Centos 5 when mailx was used by a program started by a cron job we were able to send a text file as an email message and the headers did not contain 'Content-Transfer-Encoding: base64' On Centos 7 the headers contain 'Content-Transfer-Encoding: base64' and when the client gets the e-mail they are unable to open it up. The interesting thing is that on Centos 7 when the command line is used by typing the above command 'Content-Transfer-Encoding: 7bit' is placed in the header and the client can see the e-mail without a problem. I have looked for a way to control the 'Content-Transfer-Encoding:' header to '7bit' when we use a cron job, but I have not been able to figure out how. Your suggestions would be appreciated. Thank you, -- Greg Ennis

ansible: which repo?
by Leon Fauster 06 Sep '20

06 Sep '20

What would you recommend: ansible is in EPEL8 and ConfigSIG. For the latter I do not see any sources in git.centos.org. Where they come from? I wonder with which repository I should use (long term)? dnf not checking gpg signature sounds scary: https://github.com/ansible/ansible/blob/v2.9.13/changelogs/CHANGELOG-v2.9.r… -- Leon

Updating ca-certificates
by isdtor 03 Sep '20

03 Sep '20

This is probably a stupid question: what is the correct way to update certificates if one has installed additional certs with update-ca-trust and the distro releases a new version of ca-certificates?

Tracking or checking backported kernel patches from upstream
by Carlos A. Carnero Delgado 03 Sep '20

03 Sep '20

Hi! I'm interested in finding out if a couple of upstream kernel patches were backported into CentOS (RHEL), in particular this one <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…> and this one <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…> . What's the procedure? After reading an article <https://www.redhat.com/en/blog/what-backporting-and-how-does-it-apply-rhel-…>, I went into Red Hat's bugzilla, and tried several search terms (including the kernel's commit ID) but found nothing. Thanks!

OPENVPN setup in CentOS-6 NetworkManager
by Janos G. Komaromi 02 Sep '20

02 Sep '20

Hi, I need some help. I have CentOS-6 installed on an older 32bit desktop. The command su -c "openvpn --config foo.ovpn" works well, but would like to do it from NetworkManager. (1) If I try to import foo.ovpn then the certificate file references are not populated. If I try to select files extracted from foo.ovpn then the Private key file cannot be selected and therefore setup is aborted. (2) If I create a .conf file with appropriate entries then NetworkManager imports it fully, including the .pem key file. However, connection is timed out, connection fails. I researched Internet, RFM, permissions, SElinux, messages, etc. to no avail, so I request support. Do I miss a component? Where can I examine the NetworkManager log? Why the .pem key file is not selectable? I try this mailing list first - and thank you. Janos -- Janos G. Komaromi sent it NOT from iPhone nor Google facebook, instagram, viber, snapchat, twitter, #@*~| etc. - neither of those https://jgklinux.jankom.net/

EL8: SElinux / dac_override / tmpwatch
by Leon Fauster 29 Aug '20

29 Aug '20

Hi, I'm moving some old stuff from EL6 to EL8 and one setup has a cron job which uses "tmpwatch -umc $dir" to clean some directories (/etc/cron.daily/tmpwatch). It seems that this triggers this AVC (SElinux mode is enforcing): type=AVC msg=audit(1598576896.772:4267): avc: denied { dac_override } for pid=11013 comm="tmpwatch" capability=1 scontext=system_u:system_r:tmpreaper_t:s0-s0:c0.c1023 tcontext=system_u:system_r:tmpreaper_t:s0-s0:c0.c1023 tclass=capability permissive=0 The tmpwatch exec line had "--force" before and I was hopping that this "capability" was the cause and deleted it but this night the AVC are still appearing. Is cron running in EL8 with stripped CAPs of? Does some one have an idea to address this? -- Thanks, Leon

CentOS 8 installer bug
by isdtor 28 Aug '20

Has anyone managed to create an encrypted disk partition with CentOS 8 kickstart? 1 reqpart --add-boot 2 part /boot --fstype ext3 --size=1024 --ondrive=sda 3 part pv.1 --size=1 --grow --ondrive=sda --encrypted --pashphrase="bla" 4 volgroup vol0 pv.100000 5 logvol / --vgname=vg_00 --name=lv_root --size=102400 --fstype=ext4 ... No matter what I specify in line 3, the installer bombs out. The only way to successful kickstart is to not encrypt the lvm pv. The contents of the passphrase are not to blame, installer still dies after accepting a passphrase from the console. 15:57:45,280 DBG kickstart: Looking for platform-specific boot requirements. 15:57:45,281 DBG kickstart: Applying requirements: PartSpec instance (0x7fbd40f44320) -- mountpoint = /boot/efi lv = False thin = False btrfs = False ...

CentOS7 and NFS
by Patrick Bégou 28 Aug '20

28 Aug '20

Hi, I need some help with NFSv4 setup/tuning. I have a dedicated nfs server (2 x E5-2620 8cores/16 threads each, 64GB RAM, 1x10Gb ethernet and 16x 8TB HDD) used by two servers and a small cluster (400 cores). All the servers are running CentOS 7, the cluster is running CentOS6. Time to time on the server I get: kernel: NFSD: client xxx.xxx.xxx.xxx testing state ID with incorrect client ID And the client xxx.xxx.xxx.xxx freeze whith: kernel: nfs: server xxxxx.legi.grenoble-inp.fr not responding, still trying kernel: nfs: server xxxxx.legi.grenoble-inp.fr OK kernel: nfs: server xxxxx.legi.grenoble-inp.fr not responding, still trying kernel: nfs: server xxxxx.legi.grenoble-inp.fr OK There is a discussion on RedHat7 support about this but only open to subscribers. Other searches with google do not provide useful information. Do you have an idea how to solve these freeze states ? More generally I would be really interested with some advice/tutorials to improve NFS performances in this dedicated context. There are so many [different] things about tuning NFS available on the web that I'm a little bit lost (the opposite of the previous question). So if some one has "the tutorial"...;-) Thanks Patrick

Laptop and NFS homedir
by isdtor 27 Aug '20

27 Aug '20

Afternoon, Are there any documented best practices for using NFS home directories on laptops? Right now, and this is on CentOS 7, when I disconnect the machine from the network, the desktop freezes, and I can't even tell if the machine switches to the wireless network. If this sort of adapter switching, which is standard in e.g. Windows 10, is even supported. Thanks for any insights.

Viewing changelog for packages to be updated
by Kenneth Porter 26 Aug '20

26 Aug '20

Is there some way to see the RPM changelog entries for a prospective yum update? Ideally I'd like to see just the entries that are newer than the version of the package I already have. I saw a new kernel in today's yum-cron email and I'd like to know what it's about and how urgent the issue is for me.

Hi, I am trying to create a mock configuration file that points to my local dnf repo. I have the following in the mock config template: [local-repo] name=my-Local baseurl=http://yumrepo.example.com/yum-repository/local/centos/8/x86_64/ failovermethod=priority skip_if_unavailable=False When I try to run mock I get the following error: (vgeppetto3 pts18) $ mock -v -r epel-8-x86_64 /home/mock/rpmbuild/SRPMS/centos-release-8.2-2.2004.0.1.el8.1.src.rpm File "<string>", line 238 baseurl=http://yumrepo.example.com/yum-repository/local/centos/8/x86_64/ ^ SyntaxError: invalid syntax ERROR: Error in configuration (vgeppetto3 pts18) $ I copied the url out of a yum repo file I am using that works with dnf on a centos 8 machine.

CentOS7 page-ranges printer option seems ignored
by Josh 24 Aug '20

24 Aug '20

A follow up on https://lists.centos.org/pipermail/centos/2020-July/351009.html In addition to page size problems I just found out that page-ranges option is ignored. To reproduce I created a two page PDF file and printed it like lp -d printer_name -o page-ranges=1 twopage.pdf Two local printers, HP and Canon output two pages. Printers were configured using CUPS UI by selecting the appropriate USB printer, then manufacturer and then PPD from a list of models. If I move printers to a Fedora 32 system they print correctly. Upgrading CentOS7 CUPS server from 1.6.3 to latest 2.3.3 had no effect. I wonder what else needs to be updated to resolve this problem. Thank you. -- Josh

CentOS 8 kernel-4.18.0-193 shim issue
by Mark LaPierre 21 Aug '20

21 Aug '20

Hey All, Is it safe to allow the 193 series kernel update now? Last time I tried that my system refused to boot. I had to roll back to the 4.18.0-147 kernel to get my machine to reboot. Since that happened I've been watching this mail list for acknowledgement that the problem has been corrected while refusing the kernel update. I may have missed the announcement that the issue was resolved and the the update is now approved. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Jamulus for Centos
by Robert Moskowitz 20 Aug '20

20 Aug '20

Is anyone running their own Jamulus server? I have an x86_64 system running Centos7 that I can try bringing it up for my wife. So I better get it right! I have found rpms for 3.4.7.1 at: https://pkgs.org/download/Jamulus But on SourceForge I am seeing source for ver 3.5.10. In blogs I am seeing that the better client is for at least ver 3.5.1. Are there rpms available for some 3.5 version? thanks

Boot fails with lvm snapshot
by Patrick Bégou 20 Aug '20

20 Aug '20

Hi, I have a strange problem with my centos7 file server. I have a large data storage (75TB in RAID6, managed by lvm) and each night I create a snapshot (removing first the previous one). The snapshot is mounted read-only so if a user remove a file accidentally he can restore it in the same day. However, if this snapshot exists, reboot of the server freeze at boot time and I must manually remove this snapshot. Why ? There are no entry in /etc/fstab for this snapshot, it is a cron script that manage this snapshot and mount it. Patrick

Where can CentOS7 yum-cron logs be found?
by Gunnar Niels 19 Aug '20

19 Aug '20

I'm trying to setup two CentOS7 systems with automatic security updates to run as my kubernetes nodes. I've also centralized all my outgoing mail through my mailgun service, so I've been using the cli tool "mailx", which I have configured with my credentials. Coming from Fedora32 and CentOS7, dnf-automatic had a helpful emission target that was "email_command". By default it sent notifications using this command. With yum-cron, all I see is "email", which doesn't appear to use the "mail" command. I would like to set up something myself to send the daily yum activity, but it's not clear at all where I should expect the yum-cron "stdio" output to end up at. I "started" the service, which is really just creates sentincal file to allow the yum.daily cron entry to run. However, when I look at /var/log/yum, there's nothing there of interest. I can see that it claims to have run, but I have no idea what it did. Is there another place I should be looking for what this actually did? Separately, I'm looking for a way to confirm its behavior. I was able to do this on my dnf systems by downgrading a package, but if I use `yum downgrade X` on this CentOS7 system...it just reports success and does nothing. Any ideas about that one? -GN
