You can find the slides (in German) here.
And yet another history book. “Where Wizards Stay Up Late: The Origins Of The Internet” by Katie Hafner is a great book about the early history of the internet.
You’ll learn how things started and why some things are the way they are.
1. Do not offer help for free ever again!
2. Only speak at conferences where the network is IPv6 enabled.
I’ll be giving a three hour Wireshark tutorial and a 1hour presentation about check_mk (and some other Icinga / Nagios related tools) at this years FrOSCon on August 25th and 26th. Both are in German. The tutorial is at a beginner level and hands on. So bring your own notebook. I’ll also explain some other network troubleshooting techniques.
Yes there was a time before the Internet. And people were able to communicate. In his book “The Victorian Internet” Tom Standage describes the history of the Internet before the Internet: The telegraph network. I realy enjoyed reading this book (ISBN-13: 978-0802716040).
If you need some inspiration on how to draw your network diagram take a look at Rate my network diagram.
Well maybe some of those diagrams are an example on how not to draw network diagrams.
This week I finally found the time to add them to my monitoring system using thisplugin .
Using check_mk and mrpe integrating the plugin was quite easy. I just had to add
TEMP-BL /usr/local/nagios-plugins/check_eds_tempprobe.py -H 1-wire -p 2 -w 26 -c 30
to the mrpe.cfg on my home server.
And I even get pictures:
Now I only have to cleanup my cabling and find a good position for the outside sensor.
