This was meant to be a signup form using a command-line program called arping and a ISC dhcpd.leases file on an OpenBSD 3.2 server for authenticating students' computers by MAC address in campus/student housing. Priorities changed and the signup form was postponed indefinitely.
Arping is a program that works with ARP packets on a network to identify the MAC address of an IP. Right now the script essentially parses the dhcpd.leases file to get a MAC address to compare to the arping results. Both would have to match to authenticate the user and put them in the system to have their Cisco switch port activated.
