Use dokuWiki as a document container

For an internal project, I use decentralized text files to write documentation. This documentation needs to be (re)distributed, and historical diff-info needs to be able to be shown after the decentralized documents are merged with each other and the master branch is re-pulled from the bare repository into the decenttralized devices.

The flat files themselves are possibly edited using a simple editor, like gedit. but the files are shown on the separate decentralized laptops using DokuWiki (in this case, dokuwiki is .not. per se used as the editor itself [at this moment]).

Install and run Conficker Network Scanner

The University of Bonn computer science institute's persons Felix Leder and Tillmann Werner wrote a scanner to check if there is a chance that a computer is infected with Conficker by checking the behavior of ports.

To get it running on a (clean install of Ubuntu), these actions can be taken:

First, prepare standard libraries (via python-dev) and some extraction tools (tar and unzip)

sudo apt-get install python-dev tar unzip

Sample ZFS tanks & mountpoints setup

This page will show how I added 6x1TB disks, in three different, mirrored tanks. Three separate tanks, because for usage in the file system I created three mount points in order to have each disk-pair serving one file system mount point. The reason for this is so I can use one of the three mount points as my personal-data pool (family/holiday pictures, family/holiday videos) so I can plug it out of the server and take it with me in a second in case I need to leave the premises and require a quick backup.
