Seems funny to talk about 20 year old code that was a stop-gap measure to provide a bridging function the kernel had not (as yet) got, but here it is, my old bridge code.
When I first started getting involved in Free Software, I was also involved with hamradio. In 1994 I release my first Free Software, or Open Source program called axdigi. This program allowed you to “digipeat”. This was effectively source route bridging across hamradio packet networks. The code I used for this was originally network sniffer code to debug my PackeTwin kernel driver but got frustrated at there being no digipeating function within Linux, so I wrote axdigi which is about 200 lines.
The funny thing is, back then I thought it would be a temporary solution until digipeating got put into the kernel, which it temporarily did then got removed.
Recently some people asked me about axdigi and where there is an “official” place where the code lives. The answer is really the last axdigi was 0.02 written in July 1995. It seems strange to resurrect 20 year old code but it is still in use; though it does show its age. I’ve done some quick work on getting rid of the compiler warnings but there is more to do.
So now axdigi has a nice shiny new home on GitHub, at https://github.com/csmall/axdigi
