First step, before you do anything else, is pull the hard drive, put it into a hot-swap or external bay, and dd the entire drive to an identical one. THAT goes to forensics. Alternatively, pull the h/d, put in a new one, reset the BIOS to factory settings - that includes pulling the battery... *then* set what you need, and then build it new, and restore from backups. <snip> Why, yes, we did just do this, um, last year, after a compromise via a WordPress security hole. It did not manage to get to any other systems (we checked, and only a few run WordPress). mark

determining what depends on a rpm
by Frank Cox 17 Dec '18

17 Dec '18

yum remove lightdm That command tells me that it's also going to remove lightdm-gobject and lightdm-gtk. rpm -q --whatrequires lightdm no package requires lightdm So obviously we can't take the word of the --whatrequires option from the rpm command since yum remove tells me that there are two. That being the case, using yum remove to determine the actual dependency chain is not all that helpful since (a) only the root user can do that, which seems unnecessary when all you want to get is a report about the installed packages that the rpm command can already read as a user, and (b) you're taking a chance of fat-fingering something and destroying your system by accident. Ultimately it would be very useful to have some kind of a tool that would generate a report from the rpms installed on a system and tell you exactly what depends on what else. Among other things you could use that report to remove stuff that's not needed in any installation. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

SSD no longer detected - slightly off topic
by Jerry Geis 16 Dec '18

16 Dec '18

Hi All, I have a new Samsung SSD 2T 860 type device. I connected it to my centos 7.6 system using external USB 3.1 that has power and data supplied over the USB cable. I do this all the time with a 120G SSD works fine. Formatting the device worked fine - then I mounted it and tried to copy 1.5T of data. The copy never finished through the night. I think there wasn't enough power for the SSD.... Now when I power the SSD with an external USB with power the disk is not seen when I plug it in. Any thoughts how to get the device to be seen under external USB power so I can reformat and get it going? Thanks, Jerry

SFTP - Private/Public Authentication Keysets Beyond The First Set
by Gary Braatz 15 Dec '18

15 Dec '18

I'm new to SFTP and using this mailing list was able to successfully create my first Private/Public keyset for a vendor hosting the SFTP server (I'm the client). I created the keyset by typing this: # ssh-keygen -t rsa When asked for the password/passphrase I hit <Enter> and afterwards "id_rsa" and "id_rsa.pub" were created in "/root/.ssh/". I provided "id_rsa.pub" to the vendor and when told they were ready I initiated an SFTP transfer. During the first connection I was asked for the vendor-provided password and after entering it was successfully connected to the vendor's sftp server. During successive connections I was not again asked for the password. This allowed me to create fully automated batch file transfers.my objective. Setting up my second vendor is not going as smoothly. I did exactly the same thing for my second vendor with the exception of typing "rsa_vendor2" during keyset generation (I assumed I had to use a different name for the new keyset). # ssh-keygen -t rsa_vendor2 Files "id_rsa_vendor2" and "id_rsa_vendor2.pub" were created in "/root/.ssh/" and I gave "id_rsa_vendor2.pub" to the second vendor. I initiated the first connection with the second vendor and was asked for the vendor-provided password which I entered and a successful connection was made. The problem is unlike with the first vendor I am asked for the password every time I connect to the second vendor's server. Because I am being asked for the password I am unable to create fully automated batch file transfers. The second vendor is telling me they added the public key to their server as required. Did I miss a step or do something wrong on my end? Was I correct using a different name for the new keyset or would the new keyset information have been appended to the information already in id_rsa and id_rsa.pub for the first vendor? Any help you can provide will be greatly appreciated.

CentOS7 kickstart question
by isdtor 14 Dec '18

14 Dec '18

Is it not possible to use an nfs based repo for kickstart under CentOS 7.5? E.g. repo --name=epel --baseurl=file://server/path/to/local/copy/of/epel With trial and error I figured out that this is the correct syntax to use for an nfs-based repo. But packages from this repo in the %packages section are not found. You have specificed that the package 'bla' should be installed. This package does not exist. ... It works with http off the same server and location, but I'd rather not use that. NFS installation as such, using nfs --server ... -- dir ..., off the same server and filesystem is working fine. So there is no problem here with nfs or repo setup.

Running a command at startup
by Robert Moskowitz 13 Dec '18

13 Dec '18

On a support forum, I was told that to turn off my board's blue led run: echo none | sudo tee /sys/class/leds/blue\:heartbeat/trigger Well, this does not survive a system reboot. So I was told: Add the off bit to /etc/rc.local Add it above "exit 0" So of course, CentOS is past using rc.local and recommends: # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this fi So can someone point me to how to make this into a simple systemd service? thanks

core file generation
by sthustfo 13 Dec '18

13 Dec '18

On my cent os 7 system, I can trigger a running process to dump core by sending a signal from console (kill -SIGABRT pid). However after generating some core files in this way, the system no longer generates any more core dump files. The core file pattern is set to /tmp/store/core.%h.%e.%p.%t. Is there any way to find out why the core files are no longer generated? There is sufficient disk space and permission to the folder is also intact. The initial core files generated are found in the specified folder. Any logs help explain this behavior? Thanks.

CentOS 7.6 external USB dmesg issue

12 Dec '18

I have a brand new 2T external Samsung SSD disk. (two of them) for backup. I tried the first one and had an issue, I tried the second one and got the same issue. Am I doing something wrong ? I find it hard to believe the SSD (both) are bad. I plugged in the USB 3.1 adapter, I fdisk /dev/sdd, n, p, default, default, w. then mkfs.ext4 -j /dev/sdd1, then just mount and rsync.

Install a package with repository for your system: $ sudo yum install centos-release-scl # 2. Install the collection: $ sudo yum install rh-php72 # 3. Start using the software collection: $ scl enable rh-php72 bash At this point you should be able to use php just as a normal application. Examples of commands run might be: $ sudo systemctl start rh-php72-php-fpm $ php my-app.php $ sudo yum install rh-php72-php-devel $ sudo yum install libxml2-devel $ sudo pear install Cache_Lite $ sudo pecl install xmldiff More information about this collection can be found at https://www.softwarecollections.org/en/scls/rhscl/rh-php72/ This collections is CentOS-based rebuild built by SCLo SIG community, and the packages have been available in Red Hat Software Collections 3.2 for RHEL: https://access.redhat.com/documentation/en-us/red_hat_software_collections/… So, for RHEL-based builds, follow the steps in the documentation above. About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the collection NodeJS being released here, we also build and deliver databases, web servers, and language stacks including multiple versions of PostgreSQL, MariaDB, Apache HTTP Server, Python, Ruby, Ruby on Rails and others. You can learn more about Software Collections concepts at: https://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes how to get involved and help with the effort.

Libreoffice on 7.6
by Jerry Geis 11 Dec '18

11 Dec '18

When I try to run libreoffice on CentOS 7.6 for a slide show (using my macro that I have always used since CentOS 6.0) I get a runtime error that "Presentation is not found". I updated then to the current download 6.1.2 and tried again - I get the same error. If I go back to a 7.5 machine - same macro - it works just fine. This happens on any of my CentOS 7.6 machines. Any idea why its not happy ? This is the line (second one) in the macro it gets basic runtime error oDoc = StarDesktop.loadComponentFromURL(url, "_default", 0, aProps) oDoc.Presentation.Pause = 0 There don't seem to be permission errors - everything is owned by the right user and +r etc... The error is Basic runtime error property or method not found: Presentation. What might I be missing , thanks ? Jerry

Centos7 broken after update
by Patrick Bégou 10 Dec '18

10 Dec '18

I've launch a "yum update" while I was going to lunch. 1 hour later the system was completely freezed (no mouse, no keyboard, screen black, no network). I try a hard reboot => kernel panic on the new kernel I boot on the old kernel => boot hangs with gnome-shell failure. SSH was OK so I remove the new kernel and re-install gnome shell. Reboot is ok but now the computer freeze (no mouse, no keyboard, screen black) after some time. Yum asks to run yum-complete-transaction Running yum-complete-transaction says: There are 1 outstanding transactions to complete. Finishing the most recent one The remaining transaction had 1537 elements left to run then many package to be removed and start a very long dependances check and show a lot of errors at the end with a depsolving loop limit reached: Erreur : Depsolving loop limit reached.

Weird problems with CentOS 7.6 1810 installer
by Nicolas Kovacs 10 Dec '18

10 Dec '18

Hi, I just updated my installation media for CentOS. I have a few sandbox PCs in my office, and I'm testing CentOS 7.6 1810 on them. There seem to be a few issues with the CentOS 7.6 1810 DVD. Checked DVD integrity on startup : OK. First attempt : installer froze on root password dialog. Second attempt : installer froze on dependency calculation. Third attempt : installer froze on network interface definition. Similar behavior on two different machines. On the same machine, the minimal DVD seems to work OK. I could manage to switch to another virtual console, and I have the following kernel log messages: WARNING: kernel:perf: interrupt took too long Any idea what's going on here? I should add that all the previous CentOS 7 installation DVDs worked perfectly on these PCs (Dell Optiplex 330).

Still getting Dropbox warning at login after uninstalling Dropbox
by Gary Stainburn 09 Dec '18

09 Dec '18

Lke many people I have received the message from Dropbox about their changes including the non-support for the old Linux RPM. As I no longer use Dropbox I thought I would just remove the nautilus-dropbox RPM. However, I am still receiving the warning every time I log in. Can anyone tell me what I need to do to stop this please. Gary

[OT] EPEL update?
by isdtor 09 Dec '18

09 Dec '18

Hi, OT for this list, but maybe I can get some pointers - how hard is it to get some packages updated in EPEL? The project web site sends you from link to link, and the ML web interface is horrible. No interest here to become a package maintainer or regular contributor. I have taken it upon myself to rebuild MATE from Fedora 29, seeing that the current EPEL-7 packages are four revisions behind. Also updated a few packages to their latest upstream version.

unable to stop drive timeout was reached
by Frank Cox 08 Dec '18

08 Dec '18

On a fully updated Centos 7 system with the Mate desktop, I've just encountered what appears to be a bug in.. something? I connected a USB portable hard drive and copied some files onto it, then right-clicked the icon and "Safely remove drive". After about thirty seconds I then unplugged the portable hard drive and removed it. Several minutes later a window appeared on my desktop that said "unable to stop drive timeout was reached". This is new; I've never seen it before so I think it's related to the last updates in some way. Google finds several mentions of this error message, here is one example: https://forum.manjaro.org/t/usb-drive-safely-remove-causes-delayed-error-me… -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

// RESEND // 7.6: Software RAID1 fails the only meaningful test
by Benjamin Smith 08 Dec '18

08 Dec '18

(Resend: message didn't show, was my original message too big? Posted one of the output files to a website to see) The point of RAID1 is to allow for continued uptime in a failure scenario. When I assemble servers with RAID1, I set up two HDDs to mirror each other, and test by booting from each drive individually to verify that it works. For the OS partitions, I use simple partitions and ext4 so it's as simple as possible. Using the CentOS 7.6 installer (v 1810) I cannot get this test to pass in any way, with or without LVM. Using an older installer, it works fine (v 1611) and I am able to boot from either drive but as soon as I do a yum update then it fails. I think this may be related or the same issue reported in "LVM failure after CentOS 7.6 upgrade" since that also involves booting from a degraded RAID1 array. This is a terrible bug. See below for some (hopefully) useful output while in recovery mode after a failed boot. ### output of fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000c1fd0 Device Boot Start End Blocks Id System /dev/sda1 2048 629409791 314703872 fd Linux raid autodetect /dev/sda2 * 629409792 839256063 104923136 fd Linux raid autodetect /dev/sda3 839256064 944179199 52461568 fd Linux raid autodetect /dev/sda4 944179200 976773119 16296960 5 Extended /dev/sda5 944181248 975654911 15736832 fd Linux raid autodetect ### output of cat /prod/mdstat Personalities : md126 : inactive sda5[0](S) 15727616 blocks super 1.2 md127 : inactive sda2[0](S) 104856576 blocks super 1.2 unused devices: <none> ### content of rdosreport.txt It's big; see http://chico.benjamindsmith.com/rdsosreport.txt

Can't configure GDM after update to CentOS 7.6
by Nicolas Kovacs 07 Dec '18

07 Dec '18

Hi, It looks like the upgrade to CentOS 7.6 has been unusually disruptive with the GNOME desktop version bump and a series of moving targets under the hood. The result is some wreckage at my client's desktop installations, which I've been busy to repair since yesterday. First things first. I have a custom configuration of GDM, which consists mainly of two things. 1. Display my company's logo instead of the CentOS logo. 2. Disable the user list (since I have about 100 users here). Until CentOS 7.5, here's what I did. 1. Create a file /etc/dconf/profile/gdm : user-db:user system-db:gdm file-db:/usr/share/gdm/greeter-dconf-defaults 2. Create a file /etc/dconf/db/gdm.d/01-logo : [org/gnome/login-screen] logo='/usr/share/pixmaps/microlinux-logo.png' 3. Create a file /etc/dconf/db/gdm.d/00-login-screen : [org/gnome/login-screen] disable-user-list=true 4. Update dconf : # dconf update Now with CentOS 7.6 this doesn't work anymore. The /etc/dconf/db/gdm.d directory is nowhere to be found, and I'm currently mildly cursing the GNOME developers' (and Red Hat's) policy of releasing moving targets. Until now, the whole purpose of Enterprise Linux seemed to be low-risk updates. </rant> I've documented the whole GDM customization process until CentOS 7.5 in a short article on my french blog : * https://blog.microlinux.fr/gdm-centos/ Any idea how I can configure GDM with the new version ?

DNS bind - use of /etc/named directory
by John Horne 07 Dec '18

07 Dec '18

Hello, For many years we have modified the '/etc/named.conf' file to include local settings. The disadvantage with this is of course that when bind is updated, it creates an '/etc/named.conf.rpmnew' file. We then have to determine what is new, and apply the relevant changes to our modified named.conf file. There is, however, an '/etc/named' directory which I assumed was for local configuration settings. The main '/etc/named.conf' file makes no mention of this directory, so (I suspect) any config files in '/etc/named' would, by default, just be ignored. As far as I can tell we could put our local configuration settings into a file in '/etc/named', but we would then, once again, have to modify '/etc/named.conf' to tell it to include config files in '/etc/named'. We would then be back at square one in that any bind update would create an 'rpmnew' file. I admit I haven't actually tested this, but has anyone used the '/etc/named' directory and not had to modify the main '/etc/named.conf' file? I suspect, if not, then this should be raised as a possible bug since it would make sense not to have to modify the main configuration file at all.

New CentOS7 Install Yum will not work
by Ed Morrison 07 Dec '18

07 Dec '18

Hi Everyone: I have been fighting this all morning. I did a new (several) installs of CentOS7. Yum will not update the system. I have disabled ipv6, set yum.conf to use IPv4 only, disabled firewalld, disabled selinux, used both static ip and dhcp for network connectivity. I can ping any where on the Internet, including the mirrors, DNS works and ensured the base URL line was uncommented. Any help would be appreciated. Thanks, Ed This is the latest error I am seeing: [root@localhost ~]# yum check-update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#7 - "Failed connect to mirrorlist.centos.org:80; Operation now in progress" Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=extras&infra=stock error was 14: curl#7 - "Failed connect to mirrorlist.centos.org:80; Operation now in progress" One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: extras/7/x86_64

CVE-2018-1002105
by Adam Bishop 07 Dec '18

07 Dec '18

There was a critical vulnerability in Kubernetes published earlier in the week - CVE-2018-1002105. The vulnerability has been patched both the upstream project and by TUV, but the fix doesn't seem to have made it into the CentOS OpenShift build for 3.11: http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin311/ The fixed version is 3.11.43, version on the mirror is 3.11.0. I'm not 100% certain of the support state of OpenShift in CentOS as it's maintained by a SIG, so what needs to happen to get the vulnerability patched for CentOS?

Audacious broken on CentOS 7.6
by Nicolas Kovacs 07 Dec '18

07 Dec '18

Hi, Looks like the Audacious audio player from EPEL (which has worked fine in previous versions) is broken under CentOS 7.6. It refuses to start, and when I try to start it from the command line, here's what I get.

ZFS fails with C7 957
by david 07 Dec '18

07 Dec '18

Folks I have two USB connected drives, configured as a mirrored-pair in ZFS. It's been working fine UNTIL I updated Centos from 3.10.0-862.14.4.el7.x86_64 to 3.10.0-957.1.3.el7.x86_64 The import of the pools didn't happen at boot. When I tried executing: zpool list I got the diagnostic suggesting I do /sbin/modprobe zfs And that command claimed the module didn't exist. YUM claims my updates are all up-to-date. I had to revert back to 862. Help? David

Firefox showing bogus sites after 'yum update'
by Gary Stainburn 06 Dec '18

06 Dec '18

I have just done a yum update for the first time in a while, and as part of that I believe Firefox got upgraded. After the reboot I restarted Firefox which had been closed down with the option to retain all open tabs/windows. However, when I restarted Firefox it had three new tabs, one being the ususal Firefox upgrade page. The other two were Phishing sites, one pretending to be Amazon the other I cannot remember. Has anyone else experienced this?

CentOS 7.6.1810 UEFI/Shim issue .. feedback wanted !
by Fabian Arrotin 06 Dec '18

06 Dec '18

We got some reports from people unable to reboot their nodes after updating to 7.6.1810, and basically to newer shim (v15). It seems to affect only nodes in UEFI mode, but without SecureBoot. We wrote that in the ReleaseNotes, including a link to the bug report : https://bugs.centos.org/view.php?id=15522 We have now a workaround in that bug report, and also a new interim build (not signed by Microsoft yet) but we need feedback , as the only node on which I could test this myself is my old 2008 iMac computer .. :-( Once we'll have enough positive (but also negative) feedback about this new build, we'll be able to send to Microsoft for signing and so consider that bug closed. Worth also noticing that if we can have that ready in the updates, we'll be able to spin a monthly iso that will then work on such uefi nodes too.

LVM failure after CentOS 7.6 upgrade -- possible corruption
by Gordon Messmer 06 Dec '18

06 Dec '18

I've started updating systems to CentOS 7.6, and so far I have one failure. This system has two peculiarities which might have triggered the problem. The first is that one of the software RAID arrays on this system is degraded. While troubleshooting the problem, I saw similar error messages mentioned in bug reports indicating that sGNU/Linux ystems would not boot with degraded software RAID arrays. The other peculiar aspect is that the system uses dm-cache. Logs from some of the early failed boots are not available, but before I completely fixed the problem, I was able to bring the system up once, and captured logs which look substantially similar to the initial boot. The content of /var/log/messages is here: https://paste.fedoraproject.org/paste/n-E6X76FWIKzIvzPOw97uw The output of lsblk (minus some VM logical volumes) is here: https://paste.fedoraproject.org/paste/OizFvMeGn81vF52VEvUbyg As best I can tell, the LVM tools were treating software RAID component devices as PVs, and detecting a conflict between those and the assembled RAID volume. When running "pvs" on the broken system, no RAID volumes were listed, only component devices. At the moment, I don't know if the LVs that were activated by the initrd were backed by component devices or the RAID devices, so it's possible that this bug might corrupt software RAID arrays. In order to correct the problem, I had to add a global_filter to /etc/lvm/lvm.conf and rebuild the initrd (dracut -f): global_filter = [ "r|vm_.*_data|", "a|sdd1|", "r|sd..|" ] This filter excludes the LVs that contain VM data, accepts "/dev/sdd1" which is the dm-cache device, and rejects all other partitions on SCSI(SATA) device nodes, as all of those are RAID component devices. I'm still working on the details of the problem, but I wanted to share what I know now in case anyone else might be affected. After updating, look at the output of "pvs" if you use LVM on software RAID.

CR repo update disaster for my desktop.
by Rob Kampen 05 Dec '18

05 Dec '18

I have a centos 7.5 desktop workstation with dual nvidia graphic cards running three monitors. I use the i915 motherboard graphics adapter for the third monitor with bumblebee to work the magic to enable the three contiguous work spaces. I use the kmod nvidia drivers for the two graphics cards. This has worked without a hitch for 5 months until this weekend. I enabled the CR repo and did the yum update. Some 800+ rpms were offered and all seemed to resolve depenancies OK, so yes it was started. The updates completed and all looked good, until the reboot. Initially the new kernel would boot just fine but the gdm/gnome desktop hung. No login offered. Reboot and select previous kernel, great, offered login, but the desktop barely settles before gnome crashes, and gdm restarts and I get to login afresh. Eventually I have, removed bumblebee, disabled the on board graphics adapter, reinstalled gnome multiple times, removed nvidia drivers, blown away my .gnome and related folders, tried as a new user, (no customizations of the desktop) all to no avail. Current situation is under my user account cannot get stable desktop for more than 10 seconds before it sends segfault error 4 in libc-2.17.so What do I do now? Seems that these big updates need to be applied in sub batches with reboots in between so that one can back out. Any ideas appreciated. Rob ⁣Sent from BlueMail

Accidentally nuked my system - any suggestions ?
by Nicolas Kovacs 05 Dec '18

05 Dec '18

Hi, My workstation is running CentOS 7 on two disks (sda and sdb) in a software RAID 1 setup. It looks like I accidentally nuked it. I wanted to write an installation ISO file to a USB disk, and instead of typing dd if=install.iso of=/dev/sdc I typed /dev/sdb. As soon as I hit <Enter>, the screen froze. I tried a hard reset, but of course, the boot process would stop short very early in the process. Now, I have backups of the important stuff of course, so no real catastrophe. But it would be nice if I could get back the data from my disk directly. I booted a rescue disk (Slax 9.6.4) and I can see my disks as well as raid arrays /dev/md125, /dev/md126 and /dev/md127. Oh, my partitioning scheme is manual and quite simple. Everything is RAID 1, I have a /boot array on /dev/sda1 + /dev/sdb1, swap on /dev/sda2 + /dev/sdb2 and / on /dev/sda3 + /dev/sdb3. I tried to mount /dev/sda3 directly from the rescue disk: # mount /dev/sda3 /mnt But I only get this: mount: unknown filesystem type 'linux_raid_member' I'd be very grateful for suggestions.

7.5 -> 7.6 problems
by Gregory P. Ennis 05 Dec '18

05 Dec '18

To all, I started the process of updating some of our systems from 7.5 to 7.6. Most of the servers had no problems, but several of the desktops had some difficulties. I was required to perform several yum commands to update as much as possible in the format of yum update a* then b* etc. Then after I got everything updated that would update in this manner and after the use of "rpm -Va --nofiles --nodigest" and with the use of yum update --skip-broken I am getting the following that would not update : Packages skipped because of dependency problems: libvirt-bash-completion-4.5.0-10.el7_6.3.x86_64 from updates libvirt-client-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-config-network-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-config-nwfilter-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-interface-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-lxc-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-network-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-nodedev-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-nwfilter-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-qemu-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-secret-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-core-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-disk-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-gluster-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-iscsi-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-logical-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-mpath-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-rbd-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-scsi-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-kvm-4.5.0-10.el7_6.3.x86_64 from updates libvirt-devel-4.5.0-10.el7_6.3.x86_64 from updates libvirt-libs-4.5.0-10.el7.x86_64 from base libvirt-libs-4.5.0-10.el7_6.2.x86_64 from updates libvirt-libs-4.5.0-10.el7_6.3.x86_64 from updates libvirt-python-4.5.0-1.el7.x86_64 from base Is there something I can do to finish this process or is this just related to a repository problem. -- Greg Ennis

In this script there is an occourrence to systemctl stop httpd and hostname command and I got error on permission on this 2 commands. Reading RHEL 7 SELinux Guide seems that I need a domain transaction but I don't know how to solve this. Can someone put me in the right direction? Thanks in advance.

Dell server dropping packets
by Jerry Geis 04 Dec '18

04 Dec '18

Hi All - I have a Dell R430 server running CentOS 7.5 that is dropping packets on the network. Its connected to Cisco switch at AUTO for the port. The server reports 1000M on the network. I even changed the setting for the switch to 1000M full, that did not seem to make a difference either. What else might I look at as to why its dropping packets? Its mainly 90'ish percent idle. so not doing much at this time. I have no idea what else is happening on the network. I set a windows box on the same network and just did a "ping" to the server and once in a while it lost the packets or my putty connection dropped etc... Thoughts? Ideas? Thanks! Jerry
