Hi, I'm programmer from Poland working alone on http://guardix.net project. It's software that helps keeping Cyber Cafe working properly including store management, barcode scanners suport, cash registers etc. Software is a client-server solution, management part works on Linux/Unix/*BSD and the 'plugin' that block computers works on Windows and Linux/Unix/*BSD. Problem: I don't know how to make identification key of customer's host. For example MotherBoard unique ID, is there is any posibility to get some kind of host KEY? My software is almost 'ready to sell', but I have to secure it somehow. I'll be grateful for any help, greetengs from Poland :) -- +----------------------------------------------------+ | Bartlomiej Jarocki filip at guardix.net | | http://guardix.net - Linux Cyber Cafe Software | +----------------------------------------------------+
