I need to capture packets between a cable modem and a
router for diagnostic purposes. I have inserted a hub
between them, so I can attach the Win2K system to it,
but I need to avoid having the capturing system
inserting packets of its own as it might either mask
the problem I am trying to diagnose or create new
problems.
I have downloaded and installed Wireshark 0.99.4 on a
Windows 2000 system. I am able to capture packets on
my ethernet interface with the interface enabled and
in full operation, but if I disable the interface as I
expect I will need to in order to operate "stealthy"
the interface is not available to select for capture
in Wireshark.
How do I need to configure things to be able to do
what I need? Can I define another ethernet interface
using the same NIC that has no protocols enabled on it
and then swap which one is enabled? Do I need to
disable all protocols on the existing interface for
the capture and then manually re-enable them when I
want to reconnect to the network?
Any help appreciated.
Dave
