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:...

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). I will be using 192.168.1.254 in the following Log into OpenWRT and go to System → Startup → Local Startup (the text input at the bottom of the page) and add this line above exit 0: ip neigh add 192....

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 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” IPv6 tunnels through a TUN/TAP device....

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....

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 work....

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?...
