[lab 10 poisoning and sniffing ] [ driftnet ] warning: link-level (LINUX_SLL) header is not supported

,

Hello everyone, I was working on the lab 10 and have difficulties on getting driftnet to work. When I use command (with arpspoofing),

driftnet -i tap0

I get no images. When I use the command,

driftnet

It pops up the warning message “warning: link-level (LINUX_SLL) header is not supported”. Can anyone help me to troubleshoot the driftnet? Thank you very much.

update: I can capture pictures using eth0. When I use tap0 and arpspoofing, i can see the new connections in driftnet (wtih verbose on). However, I still cannot get the pictures.
