| If AIX CDE (X11) is not used, this is Not Applicable. Check the system to determine if "X11.apps.clients" is installed: # lslpp -L X11.apps.clients If the "X11.apps.clients" fileset is not installed, this is a finding. Check if "xlock" command exists using the following command: # ls /usr/bin/X11/xlock The above command should display the following: /usr/bin/X11/xlock If the above command does not show that "/usr/bin/X11/xlock" exists, this is a finding. |
