can anyone please tell me how to obtain a processor's unique ID (if such a thing exist, which I believe does)? Or maybe some other unique number such as the Harddrive's serialnumber or mother boards unique id something. I need it to copy-protect a program which is nearly ready for distribution. Any references to tutorials of related subjects would also be much appreciated.
I don't have a CPU with an ID, so I wasn't sure if I was not seeing it in /proc/cpuinfo because it doesn't show it or because I don't have one, guess it's not there. If you are just looking for something unique, maybe try one of these:
hdparm -i /dev/hda: hard drive info
ifconfig eth0: NIC's MAC address is unique, but easily spoofed
look through the info files in /proc for something else unique
