My first project with my shiny new Raspberry Pi was to create a tool to make my job easier. I'm a network technician for a large ISP. Often times I run into equipment that has been installed in difficult to access or non-ideal conditions (outdoor cell tower cabinets). Standing around with a cable connected to my laptop isn't always the easiest or most fun to do. When equipment fails and needs to be replaced and reconfigured, I'd much rather have a wireless way to connect and sit in my truck or a more comfortable/safer spot. Summers here reach 43C and Winters get below freezing at times, especially in the middle of the night when network maintenance is done.
Hardware I used:
Prolific PL2303 USB to Serial adapter
Ralink RT5370 Wifi Adapter
Both USB devices were supported right out of the box. I didn't have to install any specific drivers.
First thing I did was remove the GUI from the Wheezy install and get rid of some packages I didn't need. This step isn't necessary, but I'm kind of OCD about what's installed on my linux machines. The following thread has some useful information: http://www.raspberrypi.org/phpBB3/viewt ... 5&p=126875
Next, I turned the RasPi into a wifi AP using this guide: http://sirlagz.net/?p=589
Once the WiFi AP was up and working, I installed ser2net and configured it for the different console settings I needed based on the devices. Some of the devices I work on don't use the default 9600 baud rate. I used the following guide and adapted it to my needs: http://mellowd.co.uk/ccie/?tag=ser2net
The last step was to get my tftp server setup on the LAN port. I set a static IP on eth0 and copied various files into my tftpboot directory (Cisco IOS and other router files). I used the following guide to setup the tftp. http://www.davidsudjiman.info/2006/03/2 ... in-ubuntu/
Next on my todo list is to find a good solution for a battery pack. There's usually always an AC outlet wherever I'm working, but I'd rather have a battery powered device to cut down on wiring, or for when there is no AC outlet. I'd like to connect a couple cables and then go find a comfortable spot to sit.
