Moving virtual machines from KVM to ESXi 6.0

I’ve been running KVM for quite a while on my lab server. It’s been running without issue but with the release of vSphere/ESXi 6.0 I felt it was time to move back to VMware. I wanted to preserve the virtual machines already running so I set out to move these to ESXi. I ran into some issues which I’m not sure is a generic problem or specific to ESXi 6.0 but I’ll describe what I…

Random desktop background from command line

As mentioned in my previous post i synchronize my wallpaper folder between my desktop computers. While the are various ways of setting a random desktop background (XFCE – which I use – has this built in), I’ve had to conclude it’s just easier from the command line. In XFCE it is not possible to do this from cron it seems, so I made a script which is run at start-up: #!/bin/bash IFS=’ ‘ DIR="$HOME/etc/wallpaper" while true  do…

Wake on WAN using OpenWRT 12.09

If you have the need to wake up machines on your local LAN from the outside, there are a few steps you need to take to get it working with OpenWRT (12.09) Select an unused IP address (which you are certain will never, ever be used).

Installing and running Copy.com agent on a headless (Ubuntu/Debian) Linux

I’ve started to use copy.com instead of services like Dropbox, SpiderOak and similar.

Why? Because it’s fast (unlike Dropbox), it’s simple (unlike SpiderOak) and it’s able to run on all major platforms (Windows, OSX, Android, iOS and Linux, both graphical and console. Both are native Linux application).

This article explains how to install the agent on Linux – more specifically how to run the console agent on a Ubuntu-derived distribution.

IPv6 with tunnelbroker.net, ChicagoVPS and Ubuntu

I have recently moved my hosting to a couple of VPSes at ChicagoVPS and wanted to use IPv6 (via tunnelbroker.net) ChicagoVPS uses OpenVZ which presents a couple of problems $ ifconfig sit0 sit0: error fetching interface information: Device not found $ sudo modprobe ipv6 FATAL: Module ipv6 not found. It turns out, this is a fairly common problem though OpenVZ is supposed to support IPv6. Luckily, someone made a small userland program (tb-tun, which “tunnels”…

iptables on a ChicagoVPS (OpenVZ) VPS

iptables is not always easy to deal with so I prefer to use Uncomplicated firewall (ufw) in Ubuntu, because it simplifies configuring and maintaining my firewall rules. Unfortunately, ufw does not play nice with OpenVZ containers so I decided to find something else. In the end (after testing various things) I decided to install the package iptables-persistent which is not as sexy as ufw but gets the job done. iptables-persistent uses two configuration files /etc/iptables-persistent/rules.v4…

Wake on LAN from WAN with a TP-Link router

If you have a computer on your local network you want to wake from the Internet and you have a TP-Link router (in this case a TL-WDR4300) you are in luck First, create a “virtual server” (or port forwarding) in which we forward an arbitrary port to port 9 at the IP address of the machine you wish to turn on (Go to Forwarding → Add New): If you test as this point, it will…

Damn you, Google!

First post in a long time – Don’t worry, I haven’t been abducted by aliens from Omicron Persei 8 So today, Felicia Day launched her new personal show called the The Flog. Since I enjoyed this first episode immensely I decided it was time to extend my use of Youtube and subscribe to the channel (user?) Geek & Sundry. To the *sshats at Google: Why, oh why, do you punish me for using Google Apps?…
