Hi Chuck, 
Thanks for the shared info.
I don't have a problem with run wireshark to capture real-time tcpdump traces from one server which is located in one hop away. No issues at all. 
But my question is, how to take such a real-time tcpdump two or three hops away.
As I described in my first email, 
I have SSH access to Server A, But I don't have SSH access to Server B. 
Server A has SSH access to Server B.
So I need to capture real-time tcpdump of Server B, via Server A.
Regards,
Luke
