gdm postsession scripts
by Leon Fauster 20 Mar '20

20 Mar '20

Its seems that only the "Default" script in /etc/gdm/PostSession gets processed. Is this the intended behaviour? This makes packaging harder. Or can drop-in scripts/files be enabled? Thanks for hints, Leon

Re: [CentOS] CentOS 8 VM 800x600
by Jerry Geis 19 Mar '20

19 Mar '20

Ok I tried that and rebooted. I get all kinds of lines in X log that says FBDEV(0): mode "1440x900" not found. FBDEV(0): mode "1024x768" not found. Funny thing is I set up a different CentOS 7 and Windows 10 guest - and they are scaling just fine and I get higher resolutions. Its just my CentOS 8 guest that is 800x600. Thoughts? Jerry

crypto-policies / per connection based config
by Leon Fauster 18 Mar '20

18 Mar '20

EL8 workstation: crypto-policies is set to DEFAULT. I need to establish a VPN connection via NetworkManager (Gnome UI) that uses a legacy protocol. Downgrading the policies globally in /etc/crypto-policies/back-ends (I do it just for one backend) helps to establish the connection. To protect this workstation I want to have this config just for this connection (its openssl based that needs opensslcnf.config adapted) and not for all openssl based services. Is a per connection based config possible? Thanks for hints, Leon

signing modules

Is there an "easy" way to just sign all kernel modules in the /lib/modules directory ? I'm getting an error about a module not being signed so not loading. CentOS 7.7 UEFI booting. (I cannot remove UEFI as hardware does not allow it). Thanks, Jerry

Xorg on CentOS
by Jerry Geis 17 Mar '20

17 Mar '20

I am trying to find a way to tell the ORDER of X drivers. I have a VM image of CentOS 7. If I boot the image I want the generic driver to load. But if I put that image on hardware I want the Intel driver to load. So if I specific the /etc/X11/xorg.conf.d/20-intel.conf and specify Intel - this is great for the physical device. But booting my image it fails cause there is not Intel hardware. How can have ONE X config that specifies Intel first and if not present load generic VGA stuff. Thanks, Jerry

Does tuned on CentOS 6.9 (i.e. tuned-0.2.19-18.el6.noarch) do any dynamic tuning, or does it only support static configuration via a static profile? Chris

CentOS rpm versioning
by koka miptpatriot 16 Mar '20

16 Mar '20

Hello Clair vulnerability scanner considers the latest version of CentOS mariadb vulnerable, because of RHSA-2019:3708 It states, that mariadb must be updated at least to the version "10.3.17-1.module+el8.1.0+3974+90eded84". CentOS' last version is "10.3.17-1.module_el8.1.0+257+48736ea6". Rpm/yum considers CentOS' version older, than RHEL's. % rpmdev-vercmp 3:10.3.17-1.module_el8.1.0+257+48736ea6 3:10.3.17-1.module+ el8.1.0+3974+90eded84 3:10.3.17-1.module_el8.1.0+257+48736ea6 < 3:10.3.17-1.module+el8.1.0+3974+ 90eded84 That's why Clair considers it's vulnerable. Is there any way to fix it? -- skype: miptpatriot

EPEL Package update?
by Chris Boyd 15 Mar '20

15 Mar '20

We run RANCID at the day job to back up switch and router configs. Version 3.11 adds some support for devices we need. The current EPEL version is 3.9. I filed a request at Fedora to get it updated, which they have completed (version 3.11), but it still hasn't made it into the EPEL for CentOS. What's the right place/process to get the update into EPEL for CentOS? All pointers appreciated. --Chris

Software gone AWOL...
by Robert Heller 12 Mar '20

12 Mar '20

I am moving from a CentOS 6 VM to a CentOS 7 VM and two pieces of software I use seem to be missing: RT (from Best Practical Solutions) -- an RPM for rt 3.1.13 was in EPel 6 and until recently, was also in EPel 7. It is not there now. Since it is just Perl code, I wonder if I can just install the el6 rpm on a CentOS 7 system. Bugzilla -- I installed this from an RPM on my CentOS 6 server (bugzilla-3.4.14-2.el6.noarch). It is not in the EPel 7. It too is noarch (also Perl code) and wonder if I can just install the el6 rpm (if I can find it somewhere -- a yum search bugzill finds it, but it is not actually there in the repo. Are there other solutions? (Installing RT "from source" is something of a bear, since there are lots of Perl module dependencies, that I would rather yum deal with if possible.) -- Robert Heller -- 978-544-6933 Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

I would like to set keyboard shortcuts for all 12 workspaces. Google shows numerous solutions for ubuntu but I cannot get any of them to work on Centos 7 with gnome 3.

System Time
by Chris Olson 11 Mar '20

11 Mar '20

A few years ago, one of our interns was curious about system time keeping features in computer systems. This intern was also the proud owner of an inexpensive Radio-Controlled Clock. The intern wondered why computer motherboards were not just equipped with a chip like the ones in the RCC so that their system time would always be correct. I posted a question about this on the CentOS email list and received more responses than those postings about problems with the new Firefox release. I must have really struck a very sensitive system time nerve. This large response was a bit of a surprise and included a bunch of time related horror stories. It became clear why using an RCC chip on motherboards would NOT be a good idea. GPS network time servers seemed to be a preferred choice. All of our bedrooms have Radio-Controlled Clocks. At 5:30 this morning, half of the clocks displayed the correct time. The other half of the clocks were incorrectly showing a time one hour ahead. Maybe this is one more piece of evidence to reject using an RCC time base for computers, at lease in thestate of Arizona.

Weird error when installing BIND on CentOS 7
by Nicolas Kovacs 11 Mar '20

11 Mar '20

Hi, I just installed a minimal CentOS 7 on an Internet-facing server. Installing BIND gives me this: Running transaction Installing : python-ply-3.4-11.el7.noarch 1/2 Installing : 32:bind-9.11.4-9.P2.el7.x86_64 2/2 /var/tmp/rpm-tmp.M6XABV: line 59: /etc/selinux/mls/rpmbooleans.custom: No such file or directory grep: /etc/selinux/mls/rpmbooleans.custom: No such file or directory /var/tmp/rpm-tmp.M6XABV: line 72: /etc/selinux/mls/rpmbooleans.custom: No such file or directory ValueError: SELinux policy is not managed or store cannot be accessed. Verifying : python-ply-3.4-11.el7.noarch 1/2 Verifying : 32:bind-9.11.4-9.P2.el7.x86_64 Should I be worried ?

Running CentOS 6 in a Docker container on a non-CentOS host
by Alfred von Campe 10 Mar '20

10 Mar '20

I have to support a legacy build that runs on CentOS 6. I’m new to Docker and would like to use the official CentOS 6.10 image (https://github.com/CentOS/sig-cloud-instance-images/blob/da050e2fc6c28d8d72… <https://github.com/CentOS/sig-cloud-instance-images/blob/da050e2fc6c28d8d72…>) as a Docker container on another host (probably some flavor of Ubuntu), but can’t figure out how to tell Docker to find that image. I also need to make some specific customizations that I would like to distribute locally but not share with upstream. Can somebody point me to some HOWTOs or tutorials? Most Google searches return how to run Docker on CentOS, which is not what I’m after. Thanks, Alfred

QEMU virt-manager video device
by Jerry Geis 09 Mar '20

09 Mar '20

I am trying to use the Video Virtio device and set it to Virtio (to get resolutions higher that 800x600). My host is CentOS 7 and my guest is CentOS 8. When I set the virtio for video - I get an add about QEMU does not support 'virtio' video device. Do I not have something loaded ? Real question is how to get video higher than 800x600. I tried every selection there Cirrus , QXL, VGA, VMVGA and virtio. Thanks, Jerry

Support for Intel Graphics 605 UHD
by Jerry Geis 06 Mar '20

06 Mar '20

I found this site https://www.linux-hardware.org/index.php?id=pci:8086-3185-8086-2212 Says the Intel UHD 605 graphics chip is supported in kernel > 4.11 centos 8 comes with 4.18 but I am not getting X on CentOS 8 with this chip. When I put this: Section "Device" Identifier "Intel Graphics" Driver "intel" EndSection in /etc/X11/xorg.conf.d it does not boot into X, when I remove it - it boots into X with generic driver - not the Intel driver. Thoughts ? Jerry
