PPPoE (Point-to-Point Protocol over Ethernet) is a protocol used by many ADSL service providers. Roaring Penguin's PPPoE software is a reliable program for connecting unix systems to PPPoE service providers without requiring any kernel patches. Note that this port has had little testing (it works on 5-CURRENT to access T-Online in Germany from the client side) and the server side is entirely untested.
