How to adapt the scap-security-guide for DISA CIS for CentOS8 Linux

admin •
The scap-security-guide changes in format with each new guide.  CentOS 8 is not fully represented within the guide.  The XMLs provided differ in context, so the RHEL XML must be used to generate the report but requires a small patch to do so. The CUI Profile The ssg-rhel8-ds-1.2.xml contains the profile cui, while the one for ssg-centos8-ds-1.2.xml does not. [root@admin...Read More »

Automated Scripted Install of WordPress on CentOS8/RHEL8 Linux

admin •
I have written a couple of installation scripts to install WordPress throughout the years.  This is the latest in that series to install WordPress 5 on a minimal install of CentOS8. Among the differences between this script and previous ones, is that this will be installed in it's own directory /wordpress rather than /. Basically, write the script as seen below,...Read More »

Linux: How to logout a user

admin •
A user was logged in via XRDP and the screen locked.  Each attempt to logon also resulted in a locked screen.  Rebooting is not an option.  There needed to be a way to identify the user and forcibly log them off, and there is. Logged on as root and typing the who command lists users and logons.  A great working...Read More »

Another way to install Java JDK 8

Oracle updates their product often and with a naming convention that doesn't permit for any reasonable guess as to what the next version should be. ...Read More »

Install DOSBox on CentOS 7
