The other day, I had to update a VM configuration managed via libvirt from the command line. There are different ways to do this. The easiest probably is to use the virt-manager application and use the GUI to modify things. ... virt-manager screenshot ... ...

This article is here as a reminder. So, for testing, I needed to configure a Cisco CSR1000V virtual router as a bridge. So I used a version 16 Cisco IOS XE image. To make my life easier I used the "wizard" that runs the first time to automatically configure bridgning. Ironically, this created an invalid ...

This article is a copy of this article and shows how to rename/change name of a network interface. Alpine Linux uses busybox mdev to manage devices in /dev. mdev reads /etc/mdev.conf and according to mdev documentation one can define a command to be executed per device definition. The command which is going to be used to change network interface name is nameif. ...

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. Would be better ...
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 that I wrote these short scripts. Remote scripts ...
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 or controller. ...

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 as NFS. FS-Cache is built into the Linux kernel 2.6.30 and higher. ...

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

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 would make a good server with low power consumption. For that I updated my NASCC firmware so that it would boot a USB key, and update my CentOS image creation script. This worked well, I was able to boot CentOS without that much effort altogether. I myself have an Epson Stylus CX5500 which unfortunately only comes with binary drivers. This was not much of a problem since the NAS200 has a i486 compatible CPU. I find this is relatively unique among different NAS models. Alas, the performance was quite disappointing. I should be used to the NAS200 underperforming. But really, this was truly sad. I did not bother to test the printing, but I did try scanning with it. Running scanimage to scan a single page was taking over 15 minutes before I hit Ctrl+C. It was an idea, but the results were so sub par. The only take-aways of this are: ...
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 cache back-end is cachefiles. Therefore, once you set up cachefiles, it will automatically enable file caching for NFS shares. ...
