Should be. The serial numbers are broadcast in cleartext. Just log all udp broadcasts to port 60000 on any net with SCO stuff on it and see ... You need to just look at the format of the udp packets, broadcast the same serial numbers from your own ip address, and that should have the desired effect of making you extremely unpopular. Repeat this process at enough Government sites where SCO have their big moneymaking contracts and /etc/cpd will disappear from the next release :-) -- Ronald Khoo +44 81 991 1142 (O) +44 71 229 7741 (H)
