  1. Install Linux on a VM or physical machine. If VM bridge the virtual NIC to the physical NIC.
  2. Get the source for rp-pppoe (google rp-pppoe) and run make install in the src folder.
  3. Edit the configuration file and set it to PAP (as it is clear text).
  4. Start pppoe-server on the Linux machine.
  5. Connect the ISP device to the Linux box (physical NIC).
  6. Run Wireshark and filter for pppoed and pppoes.
  7. You should see the user ID and password show up around the 9th packet.
