correct, Jeff has no intention of porting to linux, but the
changes to tcp_input are simple and easily understood. It
shouldn't be too hard for someone to port.

as for vacuum cleaners, in my past I once worked on a project
involving networking household appliances. I still have source
code, but alas, it is not TCP/IP based.... :slight_smile:
