Guess who's back, Don't run... I come bearing gifts... Fellas, in light of my rather long list of "noob" posts a few weeks back... I decided to go back and bang my head against the keyboard until I got the .ova file for the Debian 10 Perfect Server tutorial working in virtualbox, so that I can do my "noobie bumbling" in a slightly less public space than this forum. And, of course, I decided to keep good notes as I went, resulting in this "Annotation HowTo" that I published to help other noobs get started with the .ova file in virtualbox and, thereby, reduce the number of posts from folks like me in a forum like this. Check it: https://www.howtoforge.com/communit...-the-howtoforge-ova-file-in-virtualbox.86952/ In any case, along the way, I did run into one mystery that I can't decipher myself. Whenever I run lynis in the vbox environment, I get the following error message: Code: [+] Software: System tooling ------------------------------------ - Checking automation tooling - Ansible artifact [ FOUND ] - Automation tooling [ FOUND ] - Checking presence of Fail2ban [ FOUND ] Found no accessible config files for 'filter.d/postfix-sasl' under /etc/fail2ban Unable to read the filter 'postfix-sasl' Errors in jail 'postfix-sasl'. Skipping... I don't get this error on my prod server, that I manually configured according to the tutorial. I compared (diff) files in /etc/fail2ban/filter.d can't see anything immediate indicator of what could be wrong. Any thoughts?
