That little ARM machine is a beast in the size of a cigarette pack, featuring a total of eight CPU cores, an ethernet port and most importantly an USB 3.0 port to connect an external hard drive. It also comes with a plastic case, with a small fan inside and a PSU that is strong enough to power external hard drives connected to the USB ports. I ordered the smaller “Lite” version, which has a slightly lower CPU clock rate, but costs a lot less than its bigger brother.
In this post I’ll guide you quickly through the installation process of the ubuntu image on a micro SD-Card, how to make use of all the space on the microSD card and how to secure this little fellow a little after the installation of the image.
I’m running a Thin-Client as a home server and sometimes I need access to some files at home. Since those no-ip services didn’t prove that reliable in the past, I decided to implement a DynDNS substitute in PHP.
The concept is quite simple: Let the little server at home call a PHP script somewhere on a “big” Server that has a static IP. The big server then writes the IP to a file, so it can be read from anywhere. There are two scripts that have to reside on the big server: an index.php, which reads and echoes the IP, that was recorded, and another script in a .htaccess protected folder, which is able to write the IP of the home server to a file.
