I'm trying ssh scripted rsync using a faster cypher like you suggested and seems that transfer on 10GB is better of default selected cypher (129 sec vs 116 using aes128-gcm, I tested this multiple times). Now I will try to check on the entire dataset and see how much benefit I gain. Waiting that, what do you think about bacula as backup solution? Thank you in advance.

CentOS 7 host with guests as bridge cannot access host
by Jerry Geis 02 Apr '20

02 Apr '20

I have CentOS 7 host. Two guests on bridge network setup by GUI and virt-manager. 1 CentOS 8 guest 1 Win 10 guest Both cannot access the host. They can other machines on the network. Guests can access the internet just not the host. I used virt-manager GUi to set up everything. Selected the eth0:macvtap and Bridge. I "desire" bridge network. If I select something else I get access to host - but of course machine is not on the main network. Thoughts ? Jerry

Especially on a server. Per core temperatures in linux for Zen2 is done using (a very up to date kernel with its k10temp module). Alternatively one can look at: https://github.com/ocerman/zenpower.git I don't know if it works with the c8 kernel (but it does not work with the c7 one). But in the end. Why care about per core temperatures? Setup basic monitoring of the server using ipmi or whatever the vendor supports. /Peter K

Cloud Image building (like CentOS is doing it)

Hello, I was not able to find information about how CentOS is building its Cloud Images. I know packer etc are able to do it, but I am interested in how CentOS is building its own images as we like to adapt that for our Openstack Cloud. thanks for any hints Nicolas

centos 6 vs 7
by Divine Tanyingoh 02 Apr '20

02 Apr '20

Issue: After installing vms on vmware, I noticed a difference in behavior between centos 6 vs 7. On centos 6 I cannot ping the hostname and get a reply without first resolving in the /etc/hosts file by adding a new entry: 192.168.0.47 server1.example.com. But for centos 7 I am able to ping the hostname and get a reply even when I have not made any changes to the /etc/hosts file. Why is there this difference between centos 6 vs 7. Thank you for your assistance.

CentOS 8 Gstreamer and Mplayer
by Mark LaPierre 31 Mar '20

31 Mar '20

Hey Y'all, What replaced Gstreamer and Mplayer in CentOS 8. RPM finder finds both for CentOS 6 and 7 but not 8. There must be a replacement for them but I don't know what. I appear to be having codec issues but, not knowing what's supposed to handle the jobs that the two programs used to do, I don't know where to look for a commercial set of codecs compatible with the application. I'm getting error messages, "No video with supported format and MIME type found." when visiting certain web sites with Firefox. I would try it with Chrome but that does not appear to be available in the CentOS 8 repos either. I found solutions to this issue on the net that involved turning off HTML5 direct rendering and using Flash, but that's not going to happen. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Some problems with Unbound under CentOS8
by Carlos Lopez 30 Mar '20

30 Mar '20

Good morning, I have detected two strange problems with unbound under CentOS8 (fully patched). I have tried same configuration in an OpenBSD host, and these problems do not appear. a/ Error mesage “connection refused”. I am using this unbound server to resolv DNS records for our internal domain (Bind9 is configured to listen in localhost interface, port 5353 udp and in the same host where unbound runs). When I try to run a nslookup query like this: > set q=any > my.internal.dom ;; Connection to 127.0.0.1#53(127.0.0.1) for my.internal.dom failed: connection refused. > And I don’t understand why. Bind9 resolves this without problems, but unbound returns connection refused. Unbound is configured to listen in 0.0.0.0 and allow all connections (access-control: 0.0.0.0/0 allow). The strange thing is that it only happens with that kind of request, any other request works fine. b/ Unbound tries to connect to Root DNS servers directly. Every time unbound starts, it tries to connect to root DNS servers directly and not through internal DNS. I am using a second unbound server as a cache nameserver in a DMZ zone and unbound anchor timer service is disabled. My forward config is: forward-zone: name: "." forward-addr: 172.22.54.6@53<mailto:172.22.54.6@53> Any idea why these problems occur? -- Regards, C. L. Martinez

Upgrade to CentOS8

Hi folks I have a couple of Zotac mini PCs running CentOS7 which I want/need to upgrade to CentOS8 In theory, they are CentOS8 capable, but assuming Murphy might be lurking around, I prefer validating the hardware before starting the effective installation As there is no LiveCD, what would be the recommended way to do this?

Need help to fix bug in rsync
by Simon Matter 28 Mar '20

28 Mar '20

Hi, I've discovered a bug in rsync which leads to increased CPU usage and slower transfers in many situations. When syncing with compression (-z), certain file types should not be compressed during the transfer because they are already compressed. The file types which are not to be compressed can be seen in the man page section --skip-compress. Unfortunately skipping the default file types doesn't work and all transferred data is being compressed during the transfer. This is true for all versions since 3.1.0. Steps to Reproduce: 1. run 'rm -f Z ; rsync -azv alpha:z.gz Z' Actual results, transferred data was compressed during the transfer: sent 43 bytes received 63,873 bytes 25,566.40 bytes/sec total size is 628,952 speedup is 9.84 Expected results: No compression should happen for .gz file. Additional info: Note that the source file 'z.gz' was an ascii text file to show clearly that compression took place. Please the following BZ for more info: https://bugzilla.samba.org/show_bug.cgi?id=14323 https://bugzilla.redhat.com/show_bug.cgi?id=1816528 I tried to locate the bug in the code but failed. That said I'm not a C developer and therefore need some help from someone who understands C better than me. Any help is much appreciated! Thanks and kind regards, Simon

CentOS 8 two installs one is X and one is Xwayland
by Jerry Geis 27 Mar '20

27 Mar '20

HI All, I have two installs of CentOS 8. One is a VM and uses what sees as the OLD X as I get /var/log/X* files ... the other is on a real machine and seems to be using Xwayland and I have no /var/log/X* files. Couple things: 1) The VM is using qxl driver it seems. I do not see Xwayland running. 2) Xwayland is running on the physical box - and where are log files for it. Surprised its running two different ways. Thanks, Jerry

Hi list, I'm building a NFS server on top of CentOS 8. It has 8 x 8 TB HDDs and 2 x 500GB SSDs. The spinning drives are in a RAID-6 array. They are 4K sector size. The SSDs are in RAID-1 array and with a 512bytes sector size. I want to use the SSDs as a cache using dm-cache. So here what I've done so far: /dev/sdb ==> SSD raid1 array /dev/sdd ==> spinning raid6 array I've added "allow_mixed_block_sizes = 1" to lvm.conf to be able to add sdb and sdd in the same VG (because of the sector size missmatch). But as the LVs will only use one and only one PV I guess it's OK. # lvcreate -L 500M -n lv_cache_meta VGnfs /dev/sdb # lvcreate -l +100%FREE -n lv_cache VGnfs /dev/sdb # lvconvert --type cache-pool /dev/VGnfs/lv_cache --poolmetadata /dev/VGnfs/lv_cache_meta # lvcreate -l +100%FREE -n LVnfs VGnfs /dev/sdd # lvconvert --type cache /dev/VGnfs/LVnfs --cachepool /dev/VGnfs/lv_cache # lvconvert --cachemode writeback --type cache /dev/VGnfs/LVnfs --cachepool /dev/VGnfs/lv_cache # mkfs.xfs /dev/VGnfs/LVnfs And now I'm asking myself if I'm not doing something somewhat dangerous for a server that will be critical when in production :] The server has 128GB of RAM so maybe the caching in memory will be sufficient to achieve good performance ? What do you think ? Do you use something similar ? Thanks !

Firewalld direct.xml
by Jerry Geis 24 Mar '20

24 Mar '20

HI All - I created a /etc/firewalld/direct.xml file and put in it : <?xml version="1.0" encoding="utf-8"?> <direct> <chain ipv="ipv4" table="raw" chain="blacklist"/> <rule ipv="ipv4" table="raw" chain="PREROUTING" priority="0">-s 192.168.1.8 -j blacklist</rule> </direct> I rebooted, so then from the 192.168.1.8 machine I tried to ping the machine. I responds. I was expecting it not to respond? What do I not have right with the direct.xml file ? Thanks Jerry

Pidgin + pidgin-sipe audo/video calls to Skype for Business
by Toralf Lund 23 Mar '20

23 Mar '20

Has anyone got the audio/video call functionality to work with the CentOS 7 Pidgin packages? I primarily interested in Skype for Business/Office Communicator, but if you have anything else set up that supports audio/video, that may also be of interest. I recently tried to join a "scheduled conference", and got a (working) chat window, but didn't get any sound, and nobody else heard me. And there were no traces of video. I got an additional window with two sound-level bars, with a status line saying "Calling...", which seemed to get no further. I've tried "Test call" from the Accounts, with a similar result - a new window saying "Calling...", but no further progress. I then went ahead and tried "Call a phone number...", again from Accounts, and entered my cell phone number. Then got the "Calling..." window again, and an actual call to the mobile phone. But when I answered it, nothing much happened. The Pidgin window was unchanged, i.e. there was nothing to indicate that the call had been connected, and I couldn't hear any sound at either end. Also, there was no call signal or anything in Pidgin before I picked up. So, has anyone tried this functionality? Any luck? What's supposed to happen when I make a "Test call", anyway? Thanks. - Toralf

gnome-keyring auto locking
by Leon Fauster 21 Mar '20

21 Mar '20

Hey all, I am preparing some workstations with C8/GNOME here and wonder if there is a smart way to automatically lock the keyring after some defined time (e.g 1800 seconds). The net suggests killing the gnome-keyring-daemon process - not the smartest way. I can manually lock the keyring with seahorse but this way doesn't scale very well :-) Any hints? Leon

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

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

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

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

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

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

Anki on CentOS 7
by H 05 Mar '20

05 Mar '20

I am trying to run Anki on one of my computers running the latest update of CentOS 7. However, starting it in a terminal window shows it fails with the following messages: libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:${ORIGIN}/dri:/usr/lib/dri) libEGL warning: GLX: glXQueryVersion failed libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:${ORIGIN}/dri:/usr/lib/dri) libEGL warning: GLX: glXQueryVersion failed qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled qt: QXcbIntegration: Cannot create platform offscreen surface, neither GLX nor EGL are enabled qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled mpv not found, reverting to mplayer qt: WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed. qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled Aborted (core dumped) Anki 2.1.15-alternate comes with the QtWebEngine and I have this app running on two other computers running CentOS 7. Thus, not a general problem but probably related either to the graphics driver on this system xorg-x11-drv-ati or some configuration mismatch. It was suggested on the Anki support forum I ask in the distribution forum since they had no explanation...
