About Openkb

OpenKb.org was created to be a Administrator’s Note Center. Here you will find my personal notes on different server issues and fixes. I have been administrating servers since 1992 and was keeping my notes in my head. After a few years I then starting writing the notes down on scratch paper( Yeh , this really helped me when i needed them most). So I found this Open Source Program called “TikiWiki” and decided this was the perfect program to save my notes. Until the spammers found a exploit and I switched to WordPress .
