hey..thanks........u r cracking the PPtp ...is there anyway to do the same but for pppoe?i tried to do it the same but there is problem only in the size for the packet asleap and the scripit uses special size of chap packet..while in pppoe its random .can u help me to do it ?

[g0tmi1k]

Yea, this uses Asleap to do all the cracking, and Asleap doesn't support pppoe.
Personally, I haven't look into pppoe, so I cant help you. Though doing a quick google search:

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.

RES: PPPOE password sniffing

great tut g0tmilk?

Thanks for the thanks

Pls help u, what it mean

1. echo 1 > /proc/sys/net/ipv4/ip_forward ?
2. wireshark -e eth1 "-k ?"

1.) This enable packet forwarding
2.) Start capturing immediately (def: do nothing)
