| 13 | Set the value reported for a network card MAC address. | |
| 14 | ||
| 15 | This program demonstrates the use of LD_PRELOAD to override the value | |
| 16 | returned by the library call. The library call in question is ioctl. | |
| 17 | When called with cmd set to SIOCGIFHWADDR, we override the value | |
| 18 | returned by the system call with the value from an environment | |
| 19 | variable. | |
| 20 | ||
| 21 | To use the program, first set the environment variable | |
| 22 | HWADDR_interface to the MAC address you would like to be returned. For | |
| 23 | example, to set eth0 to 11:22:33:44:55:66, do | |
| 24 | ||
| 25 | HWADDR_eth0=11:22:33:44:55:66 export HWADDR_eth0 Then set LD_PRELOAD | |
| 26 | to the absolute path of fakeif.so and call your test program. | |
