PPS: On a consulting job one time, I helped my customer patch out the license check for some expensive Unix circuit simulation software they were running. They had bought a faster, newer machine and wanted to run it there instead of on the machine they'd bought the "node-locked" license for. The faster their simulation ran, the easier my job was. Actually, I think we patched the Unix kernel or C library that the program depended upon, rather than patch the program; it was easier.
Kernel. Instead of calling the subroutine that would retrieve the 32-bit hostid from the PROM, you just did a load immediate with the right number. The instructions were the same length, so everything worked fine :)
Not that I know of any places that actually did this, of course :) /ji --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
