Fun.. The worst thing I ever did was setup a Fibrechannel-over-IP link between .nl and Sydney. Latencies up to 1100 ms made the whole thing, from the FC perspective, umm, interesting to watch. Not useful, but interesting to see. Wilko NB: oh, I forgot the 1% packetloss, really helps for FC ;) -- | / o / /_ _ wilko@FreeBSD.org |/|/ / / /( (_) Bulte To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
