If would work with other BSDs? or Mac OS/X? possibly. fwip(4) is what Windows and a lot of other operating systems use to accomplish this feat. Last I check, it was no in the generic kernel and had to be compiled in, specified in the loader.conf(5), or loaded with kldload(8). #device fwe # Ethernet over FireWire (non-standard!) #device fwip # IP over FireWire I had the fwip driver working with a Windows XP box for a little while. It worked fairly well, but I don't think it was really any faster than ethernet (at least for what I was doign with it). Hope this helps. George Fazio N3GQF mailto:gfazio@n3gqf.us
