VirtualBox Web Interface

I am personally using VirtualBox as a virtualization solution as it fits my needs and it integrates well with Ubuntu. I recently found that you can set up a web interface and manage Virtualbox through it. In the following article I’ll describe how you can set up the web interface for VirtualBox using phpVirtualBox and I’d also like to thank the developers for doing this great job.

Free US local number pointed to your Cisco VoIP gateway

Startup scripts in Ubuntu and Debian based Linux distributions

Here are 2 simple steps which help you to run a script when your Ubuntu machine boots:

Build your OpenWRT image file

As I said in a previous post I will need an OpenWRT image set with the baud rate of 9600 bps for the console port in order to have my improvised USB-RS232-TTL adapters work.

So the other solution I thought of was building my own RS232-to-3.3V TTL converter.
