I've contacted fejed some time ago. He just sniffed on his LAN and what he wrote about is simply DHCP/BOOTP packet catched in the wild (they're sent to 255.255.255.255). If you wanna get CM configuration file you have to go one step further. Acquire similar packet from your network, take a look at it, find TFTP server address and filename and just grab this file from TFTP server. > > RFC 2669 has some interesting stuff about the DOCSIS system, though its somewhat outdated. I think that most interesting resources are at cablemodems.com and cablelabs.com. -- pozdrawiam, -= Marcin Dawcewicz =- mailto: mivat_private "When freedom is outlawed, only outlaws will be free"
