Is this at home or at the office?
Your sniffing machine (computer A) is on the ethernet segment.
Your other computer (computer B) is on the ethernet segment.
Who is computer B talking to? A third computer on the ethernet segment?
Or perhaps with a computer on the Internet, off of your LAN.
If on the Internet, how is computer B getting to the Internet? Through
it's own PPP or SLIP connection? Or through the ethernet hub to another
PPP device?
Can you give us the IP addresses of:
Computer A, computer B, the computer(s) which computer B is talking to.
Also, could you explain in more detail how all the computers
are connected on the network. Are all on the same ethernet hub? And it
*is* a hub, not a switch, right? Are there routers, PPP connections,
ISDN or DSL "modems"?
