RedHat Linux

Issue with accessing Red Hat Linux via Putty as I am not getting IP address

Below is the error message encountered, "Error: Connection activation failed: No suitable device found for this connection (device lo not available because device is strictly unmanaged).and I am not seeing Network Symbol as well highlighted below in screenshot.



Running the Command, "nmcli n on" has fixed the issue.

  • nmcli - CLI tool for manage Network Manager on Linux based systems
  • nmcli d - to list the devices managed by Network Manager 
Found this solution in this YouTube Video
