a very simple yet very powerfull password program to open a door, no network required. quick and quite secure.
install on a computer using "apt -i passdoor", then reboot the computer, read the instructions.
because it is quite stubborn and doesn't yield without a fight, uninstalling this program can be a bit tricky, you'll have to boot up the computer with a boot disk into a command shell then do the following:
/boot/network/dhcp.sys | this searches for dhcp wich login needs
/bin/login.sh username password | log in as admin/owner so apt doesn't cry
/bin/apt.sh -r passdoor | this uninstalls passdoor
reboot | reboot the system.
