CentOS

Only the different versions of the kernels were installed or deleted during the tests

That appears to say exactly the opposite of what I suggested and that you only updated the kernels. You must perform all updates, not cherry pick the ones you think you want.

Make sure that all packages are up to date, do not cherry pick updates. They are tested as a batch not individually.

I'd guess that's because the versions of the openldap packages that are in the baseos repo differ from the openldap-servers package from EPEL. The baseos packages are all 2.4.59-4.el9_0 vs the EPEL one which is 2.4.59-1.el9 and probably needs rebuilding. I'd suggest raising a request on bugzilla.red...

Judging by the path involved, that's part of jboss which is another Red Hat product. https://access.redhat.com/security/cve/cve-2021-4104 https://access.redhat.com/solutions/6577421 The second link can be read if you sign up for a free Red Hat Developer Subscription.

I'd guess your Meraki is fiddling with the SSL connection.

To use NFS you need uids to match exactly between all systems that use it.

What sort of controller are the disks attached to? If it's PERC Sxxx then it's FakeRAID and you need to go into the controller BIOS and set it to AHCI mode, not RAID, then do the install and create a linux software RAID array instead.

so it should match "first" even when the default route is added "prior".

IIRC, it won't let you add a route via a destination it cannot currently reach, hence the need to add the specific route before you can try to add the default route via it.

OVH use a weird network setup where the gateway is not in the same subnet as the host ip. You have to do special stuff to add a route to the gateway ip via the device prior to adding the default route. Something like

ip ro add 2.3.4.5 dev eth0
ip ro add default via 2.3.4.5

No. You appear to be looking for a fix for this vulnerability for CentOS Linux 8 and that went EOL at the end of December 2021 and there are no more fixes published after that date. If you are still running CentOS Linux 8 then you need to migrate to a different distro - either one listed in my SIG w...
