yum not updating dependency during install
pe flag

I have a situation where my-software requires my-common via:

Requires: my-common >= 1.2.0

During yum update my-software, my-common is not upgraded, and is left at version 0.0.1.

Why is yum not updating my-common -- and the install of my-software completes without error, even though the dependency for my-common is not resolved?

NFS mounted XFS file systems not visible using xfs_quota
de flag

With CentOS7, I made the leap to XFS (from ext4) and since then I have been unable to query quotas on NFS Clients via the quota or xfs_quota commands. The xfs_quota command also does not report any information relating to the NFS mounted XFS file systems. The CentOS7 NFS Server does enforce those quotas over NFS, which is nice, but that can be even more frustrating when NFS Client users bump up aga ...

Tenable su+sudo and selinux
in flag

My Not-A-Sysadmin-Boss wants me to explain this but I can't really find an answer? When using TENABLE SC to scan a RHEL7 system the account used to do the scan connects via ssh then uses sudo to perform its checks. But when selinux is enforcing some checks cannot be performed, one such check does a cat of /etc/passwd but is denied when selinux is enforcing. The work around is to configure SC to use s ...

Linux - User name with a "$" cannot sudo
cd flag

We are beginning to add our RHEL 7.9 Linux machines to AD. As a part of that we would like to restrict the use of sudo to the administrators. The admin group we will call ServerAdmins and we added it to the sudoers file. The issue we have is the individual administrator ID has a "$" in the name. EXAMPLE: admin$user. When we add this line to the sudoers file it fails.

RHEL 7.9: rpm --eval "%dist" is now .el7_9 instead of just .el7

Here, we've recently upgraded some of our systems from RHEL 7.8 to RHEL 7.9, and I'm facing an issue related to the "dist" returned by the rpm tool.

In some scripts, we share between RHEL7 and RHEL8 systems, we use the command: rpm --eval "%dist" to determine the local RHEL flavor: ".el7" or ".el8"

Starting with RHEL 7.9, the command now return: ".el7_9" instead of just ".el7".
