I'm playing with pppoe for the time being and I noticed something rather peculiar. I'm authenticating against radius server, and the Authentication says it is PAP - eg. clear text passwords. I've read through rfc 2516 and there is nothing said about the authentication with password. I'm wondering whether there is a way to sniff such passwords? I tried sniffing my own connection when I was connecting to the pppoe NAS but no luck. Where are the password and username contained - in the payload of some of the PAD* packets?

Regards.
