Server Howtos

These howtos are offered to both newbies and extablished SysAdmins who want to put a RHEL/CentOS/Rocky Linux server into operation either in a home or an office. They are offered without warranty; i.e. you use them at your own risk. They are taken from a working system, and in some cases I have kept my real-world domain name references to make it easier for you to understand. This is part of a project to remind me to document how I set things up, so more may follow when time/energy allows.
