This document is of interest to customers installing APPX on an Intel/Unix platform, such as Linux, SCO, and NCR Unix. APPX versions prior to 4.1.8 require a HASP because Intel/Unix systems don't enforce unique CPU serial numbers. Versions after 4.1.8 can use the MAC address of the ethernet card and do not require a HASP.
APPX uses the MAC Address of the ethernet adapter as the serial number for Linux registrations. This document provides instructions on how to determine that number.
