A strange rdiff_backup error and its solution

Author: Stephan  |  Category: Linux, Netzwerk, Sonstiges

After a longer migration of rdiff_backup repository (4 Weeks) I got this strange error

[03/20/13 13:31:44] Exception 'Found too many current_mirror incs!' raised of class

What happened ? Because of the very long Migration of the repository more than one current_mirror Statusfiles had been synced.
In the errormessage above it had been two files .
how to solve ?
Simply delete in all rdiff_datadirs all current_mirror* files except the newest one and your rdiff_backup is running again

Numlock Madness with my ubuntu netbook

Author: Stephan  |  Category: Linux, Netbook

Last weekend my netbook had a very strange behaviour. When pressed “O” a “6 “appeared instead .; instead of a “.” a “,” appeared and so one.
It was the behaviour of a constantly pressed FN Key.
After an hour of debugging I found the solution. I used an external keyboard some days before ( with NUM Lock ) and my system saved this setting. releasing NUM Lock and the strange behaviour was gone.

1-wire Problems with ubuntu and ds2490

Author: Stephan  |  Category: Linux, Netzwerk

After installing a new 1-Wire controller onto my Ubuntuserver the load was raising to 3 and higher and the server wasn’t manageable.
The Problem was the kernel driver. After unloading thecorrosponding modules and editing /etc/modprobe.d/blacklist
the system was operable again

blacklist wire
blacklist ds2490

After that I build owfs and everything was fine

custom hosts file for DNS-Problems

Author: Stephan  |  Category: Linux, Netzwerk, Weltgeschehen, windows

After big DNS-Problems at DENIC , manager of the .de domain, I think its not the worst idea to have a hostfile with the most important IPs.

A suggestion google.de ixquick.com heise.de wikipedia.org tagesschau.de robtex.com

This File belongs into the directory /etc at Linux Systems into %windir%\system32\drivers\etc at Windows Systems.
You should use this file only in case of DNS Problems
