Becoming Your Own ISP, Just for Fun

When moving into a new house, it’s important to arrange for the connection of basic utilities. Electricity, water, and gas are simple enough, and then it’s generally fairly easy to set up a connection to an ISP for your internet connection. A router plugs into a phone line, or maybe a fiber connection and lovely packets start flowing out of the wall. But if you’re connected to the internet through an ISP, how is the ISP connected? [Kenneth] answers this in the form of an amusing tale.

It was during the purchase of data centre rack space that [Kenneth]’s challenge …read more

Dummies Guide to Reverse Engineering

[Juan Carlos Jiménez] has reverse engineered a router — specifically, a Huawei HG533.

Over the five part series, he walks through the details of identifying the hardware serial ports which open up the doors to the firmware and looking at what’s going on under the hood.

The first part deals with finding the one or several debug ports on the hardware and identifying the three …read more

[Huan] Liberates a Router

[Huan Truong] was given a WiFi router and thought he’d improve it by installing a free firmware on it. Unfortunately, the router in question is a bit old, and wasn’t ever popular to begin with, which meant that it was unsupported by the usual open firmware suspects. The problem was that it only had a 4 MB flash to boot off of, but [Huan] was determined to make it work. (Spoiler: he did it, and documented it fully.)

The flash workaround consisted basically of repartitioning the space, and then telling u-boot where to find everything. On a router like the …read more
