Admin@LearnRHEL - Int.009 - Using hostnamectl
Target Audience: #Linux Users and Linux Engineers of #RedHat variants (#RHEL, #CentOS, #ALMALinux, and now #RockyLinux).
Subject: Using hostnamectl to its full potential.
Details: Hostnamectl is a very powerful and diverse tool. It can perform: the obvious renaming of your host; and alter other fields of interest about the host such as icon-name (which may be of some use), chassis (which may or may not be useful depending on its application to your needs), location (which can be useful to imply geo-location or office-location),and deployment (implying “environment type”).

      You are welcome. I am glad there was enough audio loudness for your to accomplish your task. I am reworking many of the videos on my channel due to the lack of loudness and have not even started on the Gitlab-associated videos yet. Those will come in due time. Glad this worked for you though!😃

    • @learnrhel8291
      @learnrhel8291 Рік тому

      No, as this is a matter of system security you really want to create the aide.db.new.gz, and then rename/move it to aide.db.gz with ownership as root:root and limit the MODE to 0600 (-rw-------). You can generate the aide DB using the command "sudo aide --init" but remember to move the file to drop the "new" part, as I indicate above.
