This article is on using rsnapshot and an external inexpensive USB drive to back up personal data easily. |
Zabbix is a very complex software that takes weeks to fully understand. One of the most interesting, most complex and least documented features are escalations. They are used to define a schedule what Zabbix is supposed to do when a certain event occurs. Like waking up the system administrator or do some automatic emergency cleanup tasks. |

If you need to rename a larger number of files following a certain pattern then you will long for an automated solution. The 'rename' command helps you here that is (at least on my Debian installation) part of the Perl installation. All you need to know is the basics of regular expressions to define how the renaming should happen. |
Many system administrators seem to have problems with the concepts of pipes and redirection in a shell. A coworker recently asked me how to deal with log files. How to find the information he was looking for. This article tries to shed some light on it. |

After I went from analog cable TV reception to a shiny satellite dish on our roof I was facing new challenges. Like how the hell do I watch TV on my workstation now and how do I record programmes to DVD now? Luckily the watching part was a cakewalk thanks to kaffeine.

Sometimes a network service is just not behaving the way it should. And the log files do not help you either. Then it is time to use the power of tcpdump and Wireshark to get a deeper look on what is actually happening on the wire. If you have an X11 running on the host in question you may just start Wireshark and start recording the traffic. However often you need to record traffic that is running on a machine you can just login through SSH. Don't panic - you can still analyze the traffic. |
Usually modern desktop Linux distributions make it easy to automatically mount external storage media like USB flash sticks. But if all else fails this article may help you. |

Bacula is a nifty backup software that is network-capable and stores data in the database for faster retrieval in case you need a certain file back. As a big fan of cheat sheets I created this cheat sheet. |
