Linux Administration Challenges
1) Upgrades and patches
a. Sometimes patching doesn't address all software. Some software
needs to be
patched separately from OS
b. Some software libraries need to be manually removed
c. Sometimes the recommended steps result in inconsistent updates

b. Validation of the systems after configuration changes is a
challenge on many
occasions. Sometimes we identify issues and broken dependencies
with nowhere to go.
Major issues to address
Linux kernel upgrade issues - There are many CentOS machines which
are appearing in report
as due for kernel upgrade. CentOS 7 is the last supported CentOS
version and will be ending the
support in 2024. CentOS 8 is not supported anymore. There are
several machines having
CentOS 7 & 8 as the OS and the recommendation for these machines in
to move to a different
supported flavor of Linux. These servers are hosting applications
such as NFS shares, Splunk
forwarders, Rapid 7 scanner, Zabbix etc. After rebuilding the
servers these applications need to
be properly configured and tested.
Linux Upgrade issues - There are several machines on Debian 10
which is losing support soon.
We know the process to upgrade them to Debian 11, but this doesn't
solve all the issues. There
are still references to old vulnerable libraries and software which
need to be cleaned up.

Openssl, rubygems , icu, etc.
which are reporting a referencing old libraries or vulnerable
