Cloudflare has upgraded their API to version 4 some while ago. https://api.cloudflare.com/#user-level-firewall-access-rule-properties I want to use the new APIs to block IP addresses using fail2ban. Using curl directly is a bit cumbersome, so I created a few php helper scripts. They can also be used in other projects. Thanks to andrieslouw at github https://gist.github.com/andrieslouw/3c833332cbf66f95ca6751f82013acf5 I didn’t […]

During boot up, grub was showing the error “Begin: Waiting for root file system… …” And after a minute or two waiting. “ALERT! /dev/sda1 does […]
MK809 II Picuntu upgrade to Ubuntu 14.04
Many moons ago I bought a MK809 II Android TV stick. This is a popular RK3066 device that one can flash G8’s Picuntu image, and run Ubuntu server on it. It was bleeding edge stuff where you could install an armhf version of Ubuntu 12.04 onto the stick. It makes an ideal “stick server” […]
