The goal of a sysadmin

January 13, 2021 | Philosophy

Providing infrastructure, including IaC with high availabillity and single point of failure in consideration. Help developers containerize and deploy their code. Make sure the organisation is compliant with any legislation (as GDPR). Make use of, and implement encryption, where ever nessesary. Diversify, Segregate, Hash, Backup and implement the Priciple of Least Priviledged in your infrastructure.

There are two sides to a being a sysadmin: Behind the scenes and in front of the scene!

You may get credit for the first and get bashed for the latter. But, both seems to be expected of a sysadmin.


I'm a Sysadmin, network manager and cyber security entusiast. The main purpose of this public "notebook" is for referencing repetitive tasks, but it might as well come in handy to others. Windows can not be supported! But all other OS compliant with the POSIX-standard can (with minor adjustments) apply the configs on the site. It is Mac OSX, RHEL and all the Fedora based distros and Debian based (several 100's of OS's), all the BSD distros, Solaris, AIX and HP-UX.
