Hello, I think I find out why :
http://sources.debian.net/src/macchanger/1.7.0-1/src/mac.c In mc_mac_random() [mac.c:71] - 'mac' argument is saved into 'newmac', on the stack [mac.c:79] - every byte of 'mac' is randomized [mac.c:87] - 'mac' is overwritten by 'newmac' value (original 'mac' value at function entry) [mac.c:105] Thank you -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
