IIRC, there have been such incidents in the U.S. in the past, where a single party on dialup or cable modem could fux0r up their entire ISP. Try running a BGP daemon on your ISP's account, chances are, you can publish some bogus information as well. > There's a lot of very well developed routing best practices (just walk into > any nanog, ripe, apricot etc meeting for discussions, tutorials etc on > these, or troll through google). Pity is that some providers are just too > dumb to follow these. Look at the amount of best practices a voxel of vacuum has to follow to route electromagnetic radiation. In principle, routing packets from here to there can be done by very minimalistic decorations on top of that physics. The network is not nearly dumb enough yet. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
