DoorJam is the meatspace firewall for sudo room

sudo aptitude install build-essential libusb-1.0-0-dev libnfc-bin

npm install

Users swipe their access card in a Magtek USB magnetic swipe card reader and if the hash of their card data matches a hash in the access control file then a character is sent over serial to an arduino that then closes a relay for a number of seconds to open the door.

If the card is not recognized then its hash is logged in the failed_attempts file with the date and time of the attempt.

Swipe a new card and run the grant_access_to_last_failed_attempt.js script to grant people access.

sudo cp doorjam.initd.with-forever /etc/init.d/doorjam
sudo update-rc.d doorjam defaults

Now edit the /etc/init.d/doorjam file to ensure all paths are correct.

sudo cp doorjam.initd.no-forever /etc/init.d/doorjam
sudo update-rc.d doorjam defaults

Now edit the /etc/init.d/doorjam file to ensure all paths are correct.

Change the IP, path and :

ssh root@192.168.1.2 "cd /root/doorjam; ./grant_access_to_last_attempt.js <name and contact info of new user>"

You can also use the sudo_grant_access.sh script, but you should edit it to suit your environment.
