Recently I looked into WANEm, an open source WAN Emulator. However, despite being open-source, GPL-licensed, the source of the actual emulator elements (scripts, PHP site etc) did not seem to be available outside of the ISO live CD image. Whilst the live CD is very useful, it is always nice to access the code without needing to fire up a virtual (or real) machine.
So, in order to learn a little more about what was happening in the code, I’ve uploaded the source to GitHub:
