The program should be run just before the intended target user is about to log in. When run, the program will wait for the user to log in, hijack the session, and grant the specified user a security equivelance of the attacked user. With all addresses you must specify the Netork address, not just the MAC address. After setting the corresponding values, compile the program. The final step before running the program is to install a packet driver on INT 0x60.
Most network cards come with a packet driver on the installation disk.
If you do not have the installation disks, or the disks do not have the drivers on them, many drivers for many cards are available on the web. Normally you must specify which interrupt to use for the packet driver, if so, use 0x60. Just before the intended target is about to log in, run the program. Assuming you've set everything up correctly, the session will be hijacked, the specified user will be given a security equivelance of the attacked user, and the program will terminate. Now, reset your system and log in as the user who was granted the rights.
