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

by lejeczek 22 Nov '20

22 Nov '20

hi guys I've just gotten a bunch of updates via yum and something weird seems to be going on after the update. System has: selinux-policy-3.13.1-268.el7_9.2.noarch selinux-policy-targeted-3.13.1-268.el7_9.2.noarch actually three different boxes, all the same: $ semodule -l No modules. and an attempt to install modules fails: $ semodule -i openvpn.pp Failed to resolve typeattributeset statement at /etc/selinux/targeted/tmp/modules/400/pe-openvpn/cil:1 semodule: Failed! Does above "usual" work for you? many thanks, L.

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.)

Help with VirtualBox on CentOS 7
by Jerry Geis 19 Nov '20

19 Nov '20

Any Virtualbox on CentOS guru's out there? I only have 1 VM on my linux host. in the update process to virtualbox 6.1.16 my config was lost. When I run Virtualbox my VM does not show. So I desire to add it back. My structure is this. ls -l /home/silentm/vmware/CentOS\ 64-bit\ LSI/ -rw------- 1 silentm silentm 8684 Aug 13 08:31 CentOS 64-bit LSI.nvram -rw-r--r-- 1 silentm silentm 0 Feb 27 2017 CentOS 64-bit LSI.vmsd -rwxr-xr-x 1 silentm silentm 2735 Aug 13 08:31 CentOS 64-bit LSI.vmx -rw-r--r-- 1 silentm silentm 272 Feb 27 2017 CentOS 64-bit LSI.vmxf -rw-r--r-- 1 silentm silentm 32796639232 Nov 17 08:34 CentOS 7-64bit LSI.vmdk -rw-r--r-- 1 silentm silentm 107382571008 Aug 13 09:05 CentOS 7.vhdx -rw-r--r-- 1 silentm silentm 323155 Aug 5 08:39 vmware-0.log -rw-r--r-- 1 silentm silentm 323085 Jun 30 14:14 vmware-1.log -rw-r--r-- 1 silentm silentm 256013 May 31 10:09 vmware-2.log -rw-r--r-- 1 silentm silentm 322239 Aug 13 08:31 vmware.log When I click add and goto the directory above - IT ONLY wants to add *.xml and *.vbox. So that is no good. When I click New and Enter my name, and use existing disk - it does not like that either. How can I get this same VM to be in my menu and run again ? Thanks, Jerry

(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. It recognizes the raid, but boots randomly with root on /dev/sda1 (and recognizes raid with /dev/sdb disk), or with root on /dev/sdb1 (and recognizes raid with /dev/sda disk). When booting from Linux Rescue CD, the raid with two disk is recognized.

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!
