Question : sharing open ports in c#

I am looking to attach to an open port used by ETRADE on my local pc. I would like to open the same port and catch the same data that is being sent down by etrade into one of my c# applications. Can anyone point me in the direction for sharing open ports?

Answer : sharing open ports in c#

i don't believe have 2 listeners on the same port and path but you can probably write some kind of packet sniffer application to get the info that is coming into port.

i don't know how helpful it will be but here is a link that has links to tutorials.
