At least Windows, most linux flavours and Mac OS X which make out the rest of the machines on our network here at Meraka Institute. One thing that I have against the way the stuff in -current is done at the moment, is that it seems to be a lot more work to just get ipv6 to work. Either I did things wrong or we are taking a step backward. Make no mistake, I like the idea of being able to control it per interface, but it seems that you have to enable it per interface with a long string for each... I would rather that it is enabled everywhere by default and then you disbale it where you do not want it. John -- John Hay -- jhay@meraka.csir.co.za / jhay@FreeBSD.org
