For the last few months I have been struggling with getting a Sun 2 (SunOS 3.3) to route TCP/IP over AX25. I have KA9Q net running (well just) but that is not really a good solution (for me) for a number of reasons that I won't go into here. So I have tried to come up with a solution that gets my packets for the AX25 network into and out of the kernel in order to use all those nice BSD comms facilities. I have looked at SLIP and and Julian Onions Tunnel Driver - but I need to do some hacking on these drivers and this is where my problem arises. I find after looking at all the header files and reading Leffler et al's wonderful book that there are still huge holes in my knowledge about how things work in the kernel and in the internet domain in particular. I don't have access to the source, but there must be more documentation and that's where I am asking for help. Does anyone know of any documentation that describes the data structures and data flows in a SunOS kernel especially the handling of TCP/IP.
