Even better, a blackhole route is better from a usability perspective i.e something like (hopefully right syntax): ip route add blackhole ipaddress or we can even send ICMPs back with "prohibit" in place of "blackhole" A qdisc would probably be the last thing on my mind to achieve such a goal. Note, one could argue that this could be because upto now, no such qdisc has existed ;-> I dont mind its inclusion (despite the oddity). cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
