This is commonly done by those whose wish to gain access to a wireless network - by monitoring transmissions, you can pick up macs of connected devices, then spoof the mac to pretend you are one of those. (And no I don't!!) :rolleyes: | wuppo (41) | ||
| 384273 | 2005-08-29 22:05:00 | Hi beama I got the code to work - there are a couple of formatting issues when you copy and paste the code. The crrected code can be seen here. (www.vbaexpress.com) Thanks again for pointing me in the right direction. Chill - as Graham alluded to in his post, it is one measure of security to ensure copied versions of my software won't run on any PC other than my own. Given it has weaknesses, it's only one measure. Cheers, Andrew |

| 384275 | 2005-08-30 02:18:00 | The Burroughs mainframes had a system serial number wirewrapped on the backplane. ;) The MCP and all the other system software was licenced for one system, and there was probably a card containing that system number in the source deck. Of course, there wasn't much chance of getting away with pirating the software; even if there was any incentive: apart from anything else there weren't that many machines in the world. (I think, about 5 in NZ). The MAC address might be saved somewhere in Windows I don't know. Windows certainly knows how to find it. That might not be in the main DLL zoo; it could be in the TCP/IP code. You could certainly discover how it's found by looking at the source code of a Linux Ethernet driver. The Intel CPU serial number is disabled by default. It's probabaly enabled in the BIOS, but I haven't got any idea how it's accessed. |

(I think, about 5 in NZ) . About the only hack I heard about was the "warning" which said something like: [b]Do NOT cut the wire going from pin 48 of slot 12 on shelf 12 in cabinet 06 to pin 23 of slot 8 on shelf 11 . Doing this would make the CPU run at twice the standard speed[b] . The MAC address might be saved somewhere in Windows; I don't know . Windows certainly knows how to find it .
