You can use the -i argument to specify the interface tcpflow should
use. If you get 'interface not configured' it means you have to
configure the interface via the operating system (e.g. ifconfig).

ummmm... Okay....
So exactly how should it be configured?
Any help greatly appreciated. I am also having the Device not configured errors...

type ifconfig -a
at a command line...this is as far as I have gotten on this. Any help would be appreciated.

Sounds like you should try BrickHouse, download it from versiontracker.com
with it you can monitor ethernet, PPP, PPPoE, Airport and IP Gateway you'll like it
let me know

This is a fantastic utility. Check this out: I have my Mac and a PC connected to a small hub on my desk. That's connected to a hub in the next office. When my PC has TCP traffic, TCPflow picks it up. Why is that? More interestingly, I can see the passwords (transmitted in clear text by Outlook) when the PC checks my email! What if I were connected to a larger hub at an office where it mattered? Could I see everyone's usernames and passwords when they check their email?

>When my PC has TCP traffic, TCPflow picks it up. Why is that?
What you are witnessing is the difference between a hub and a switch. Incoming traffic from a hub will be broadcasted to any machines connected to it. Packets that are not intended for your IP are normally ignored, but packet sniffers log the receipt of the packet.
Switches only send packets to the machines that they are intended for.

How interesting! Thanks very much. I new that a switch was more secure, but had never actually witnessed how public the information is!

I think TCPflow picks up the data going to the PC because in the Ethernet specification(Carrier Sense Multiple Access/Collision Detect) frames go to every interface on the collision domain(any interface connected by a link-layer device like a hub).
Anybody know how to configure tcpflow for a pppoe0 device??
