If you're using PAP as an authentication scheme you must look into the packets that follow the PPPOE session, after you've found a PPPOE access concentrator a PPP session is established. You must look for a packet that is sent by the authenticating terminal (in this case your computer) to the concentrator. Try to do a wireshark capture and apply this filter rule "pap and eth.src==XX:XX:XX:XX:XX:XX", and replace the x part with the terminal's mac address. If a frame matches the filter it should contain the user and password in the payload. Check out RFC1334 for more info. -- Alex Nedelcu CCNA, SNRS, CSVPN ------------------------------------------------------------------------ This List Sponsored by: Cenzic Need to secure your web apps?
