fail2ban ban not working
by Gary Stainburn 08 Apr '20

08 Apr '20

I have fail2ban on my mail server monitoring Dovecot and Exim. I have noticed that it has stopped banning IP's.

C8.1 Grub problem
by Alessandro Baggi 08 Apr '20

08 Apr '20

Hi list, I reinstalled on my workstation CentOS 8.1. I explain: I'm a KDE user but packages shipped from EPEL currently are buggy so I prefer a stable and functioning system to work with. So I tried to remove KDE workgroup and installed group "Workstation" but the system bricked so I reinstalled with GNOME. I've an nvidia gtx 1050ti GPU so I installed kmod-driver from rpmfusion. After the installation of Nvidia driver, I rebooted, gdm start and after I perform the login the system freeze. So this problem happened to me with C7.5 and nvidia driver. In my case I need to blacklist i915 module and system works. Also in this case I tried to boot centos changing grub kernel parameters pressing 'e' in the grub menu and adding "i915.modeset=0 rd.driver.blacklist=i915", booted and system works. So I tried to make this permanent updating grub configuration adding the previous directives (and removed rhgb and quiet) to /etc/default/grub and run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg. Reboot the system and checked again kernel parameters on grub menu and seen that nothing changed. Booted and freezed. I checked /boot/efi/EFI/centos/grub.cfg and kernelops has the new directives. Seems that grub configuration does not take effect. I made another test inside a VM installed with minimal selection and remove rhgb and quiet parameters and worked fine. The vm is BIOS and my workstation UEFI. How I can solve this problem? Currently to boot my system I need always to add this params. Thank you in advance

The community will instantly recognise both from their long standing and well established support for the CentOS Project over the years, initially as consumers and community participants, and in more recent times as active across various initiatives in and around the project space. Over the last sixteen years the CentOS project has established itself as a critical component in the open source ecosystem online. In order to maintain this leading role and help drive success for the wider open source ecosystem, we are moving to a more contributor-centric model. A key part of enabling this goal is to evolve our transparent governance. Pat and Thomas have shown keen interest in participating in this specific endeavour, and we are excited to welcome them to the team, helping us get there. Thomas (alphacc) works in the Controls group within the CERN Beams department [3]. He has contributed to the CentOS Project since 2012, as a member of the infrastructure team. He helped to bootstrap a few Special Interest Groups, helped the QA team with reports, and now mainly designs and improves the Community Build Service [4]. Thomas?s sponsor on the Board is Mike McLean, who will help oversee his transition to project leadership. Patrick (jcpunk) works at Fermi National Accelerator Laboratory [5]. He is part of the Scientific Linux team [6] and works on systems that perform Data Acquisition for various experiments at Fermilab. Although a long time member of the community, formally Pat began working with the CentOS Community when Fermilab decided to use CentOS 8 [7] as its EL8-base platform. Pat?s sponsor is Johnny Hughes, who will help oversee his transition to project leadership.

C7, odd log off issue

Fresh C 7 install, fully updated... but whenever I go to log off, whether with ctl-alt-delete, or from the menu, instead of logging me off, it restart X, with me still logged on. The second time I try, it logs me off. Anyone seen this behavior? mark

CentOS 8.1 cron does not send mail
by Tobias Kirchhofer 06 Apr '20

06 Apr '20

Hi, we experience difficulties with crond behaviour sending mail since CentOS 8.1. The cron job is the same like we used in CentOS 7. crontab -l /usr/bin/python3 -c 'import random; import time; time.sleep(random.random() * 3600)' && /usr/local/bin/backup.sh backup.sh writes the backup to the remote backup server. There are around 30 machines with the same cron job. The python part spreads the jobs over an hour so that the backup server is not struck at once from about 30 machines. The change in behaviour is that crond sends no mail anymore. It is because of the logical and (&&). Without this crond sends mails. What has changed in CentOS 8 and does anyone has an idea how we could fix it? Thank you! Tobias -- collect(a)shift.agency

Trying again: KDE fails with a gray screen after login, can't reinstall
by mark 04 Apr '20

04 Apr '20

I set for graphical mode, I get the login screen, I change to KDE, and the screen goes black, then after minutes, gray with a cursor, and that's it - I left it overnight, no change. Brand new install (as of yesterday). Missed any "agree to license", and missed choosing software. Manually groupinstalled Installed Environment Groups: KDE Plasma Workspaces Development and Creative Workstation Tried to reinstall: No group named KDE Plasma Workspaces exists I'm assuming I need to install something else, but does anyone have a clue? I really do NOT want gnome. mark

Mostly better: new C7
by mark 04 Apr '20

04 Apr '20

Well, I gave up, and reinstalled C7. This time, I realized I needed to make a software choice before the install, and did so. My install, yesterday, was a minimal. Silly me, yesterday, after that, I did a groupinstall of KDE Plasma Workspaces... and it did *NOT* include all the dependencies to run KDE. Having installed a KDE desktop, much is better... with one exception: I can't seem to find any games. I tried yum groupinstall "Games and Entertainment", which showed when I did group list... and was told it was empty. Now what am I missing? I do have epel and rpmfusion, both free and non-free. mark

Upgraded to 7.10 from 6...
by mark 03 Apr '20

03 Apr '20

Let me start out by making clear I *LOATHE* gnome, ok? So I don't want to hear about it. What's happening is this: I did this: yum groupinstall "Development and Creative Workstation" yum groupinstall "KDE Plasma Workspaces" Now, when I go in graphical mode, I try to change to kde on login. Nope - minutes later, I can see a cursor, and a gray screen. Ditto on the "safe mode", and ditto on "gnome classic". What have I missed? mark

IOMMU and kernel
by Georgios 03 Apr '20

03 Apr '20

Hi. Im trying to set intel_iommu=on on kernel parameters at grub but for some reason it doesnt work. I edit /etc/default/grub file and i add the parameter. then i run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg and then i reboot. when i run virt-host-validate i get QEMU: Checking if IOMMU is enabled by kernel: WARN (IOMMU appears to be disabled in kernel. Add intel_iommu=on to kernel cmdline arguments) when i edit the grub menu durring boot and i put intel_iommu=on and the i run again virt-host-validate i get QEMU: Checking if IOMMU is enabled by kernel: PASS any ideas? I tried editing other variables like GRUB_TIMEOUT and it seems to me that changes are applied. Thanks in advance

C8 and backup solution
by Alessandro Baggi 03 Apr '20

03 Apr '20

Hi list, I'm searching a valid backup system to perform backups of 3 server, one local and 2 remote, and 2 linux workstation. (this number could be higher in future). Currently I'm testing bacula, scripted rsync with hardlink and borgbackup on C8.1. Bacula works without any problem, well tested, solid but complex to configure. Tested on a single server (with volumes on disk) and a full backup of 810gb (~150000 files) took 6,30 hours (too much). I would run deduplication but 1. bacula on C8 is not compiled with aligned 2. bacula put attention on some possibile bad scenario where deduplication could be a problem in losing one block that could break many files with the same shared block. So deduplication is secure or I should be away from it? scripted rsync. Simple, through ssh protocol and private key. No agent required on target. I use file level deduplication using hardlinks. To perform compression and block deduplication I could use fs like zfs (not available from epel) or use something like stratis (I don't checked if it offer deduplication in this moment). Encryption could be performed on fs level. Using a scripted rsync is the simpler way but there is something that could be leaved out by me (or undiscovered error). Simple to restore. BorgBackup is another solution similar to rsync in some way. It works like rsync through ssh but while rsync simply sends data, borg run deduplication, compression and encryption on place. Why is similar rsync? Because I need another script to run borg. It is not a complete solution and it works on push method and not pull like with bacula or rsync. If I would manage all my server from a central backup server is a problem, so to accomplish this I should run the borg command from the central server on the target server that point back to the remote repository (located on the central server). There is another solution with borg: using sshfs but is 4 time slower (too much solwer). I have not so much experiences on backups and choosing the bad tool could be dangerous so I need some suggestion. What backup solution do you suggest for my scenario? Thank you in advance. Alessandro.

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).

centos 6 vs 7

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
by Patrick DERWAEL 29 Mar '20

29 Mar '20

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? Thanks! <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

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

Building a NFS server with a mix of HDD and SSD (for caching)
by kadafax＠gmail.com 24 Mar '20

24 Mar '20

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 !

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

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

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
by Jerry Geis 17 Mar '20

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

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

Slightly OT : where is Cipherli.st ?
by Nicolas Kovacs 16 Mar '20

16 Mar '20

Hi, Up until recently, I've been using the excellent https://cipherli.st resource to configure SSL on my servers. I tried to take a look again today, but the site seems to have vanished. Anybody knows what's happened ? Has it moved ?
