My tale of IPv6 blues
My ISP provider is KPN. They recently enabled IPv6 in my street. I was using before a IPv6 Tunnel Broker, starting with SixXS and after they went out, with Hurricane Electric. So naturally, I decided to switch to KPN's native IPv6 service.
They provide a /64 prefix, which is reasonable …
Ad-Hoc rsync daemons
The other day I needed to copy a bunch of files between to servers
in my home network. Because of the volume I wanted to copy the files
without having to go through ssh's encryption overhead. So I
figured I could use netcat for the data transport.
To do …
Z-Wave Associations with With Vera UI
I couldn't find any to the point documentation on how to do this, so I am writing this.
The way I understand Z-Wave associations work is that once devices are in the same Z-Wave network, a device can directly send a command to another device without intervention of the Hub …
Installing Void Linux

issues around glibc, it works quite well. Most compatibility

- Does not depend on
systemd …

If you often mount and access a remote NFS share on your system, you will probably want to know how to improve NFS file access performance. One possibility is using file caching. In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such …

Windows administration from the command line
Windows system administration is very mouse driven and to reach all tools you need to browse through Windows explorer.

Using a NAS200 as a Print server
Last weekend I had a small weekend project to move my All-In-One Printer/Scanner from my Xen host server to a spare NAS200 I had lying around. Since the NAS200 has a i486 compatible CPU, and I had been able to run a CentOS 5 distro before, I figure it …
Enable local file caching for NFS share on Linux
In Linux, there is a caching filesystem called FS-Cache which enables
file caching for network file systems such as NFS. FS-Cache is built
into the Linux kernel 2.6.30 and higher. In order for FS-Cache to
operate, it needs cache back-end which provides actual storage for
caching. One such …

Askozia Desktop Appliance
So last weekend finally had some time to work with a Askozia Desktop Appliance.
It actually arrived much earlier but without a Power Supply. Initially I though, "this is strange; I didn't know this supported PoE". (Power Over Ethernet). It turns out it didn't and there was a shipping mistake …

This is done by:
- globally distributed reverse proxy cache network
