In Brussels, PhilV wrote a patch to udhcpd assign 10.x.x.x adresses from the last digits of the MAC address: http://reseaucitoyen.be/wiki/index.php/PatchesUdhcpd http://bulles.topgame.be/ReseauCitoyen/udhcp.patch -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-4148403 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators."
