Ad-Hoc rsync daemons

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

The high lights of void linux:

  • musl build - which is very lightweigth
  • Does not depend on systemd …

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 …

First of all, we must install the following components:

  • A DHCP server to assign IP addresses to our diskless nodes.
  • A TFTP server to transfer the boot image (a requirement of all PXE option roms).
  • A form of network storage (NFS …
