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. I will show the steps on how to build your image. Please note that I am using Ubuntu as OS but it should work with any other Linux distributions, you just have to install the dependencies.

Serial console cable for your Linux router

Today I have been trying to get some working console cables for the Asus WL-500 routers I have. The first thing I tried was using an old Nokia CA-42 data cable which includes an Prolific USB to 3.3V TTL converter but unfortunately it ended in getting a messy input and output. So the other solution I thought of was building my own RS232-to-3.3V TTL converter.
