Windows XP: tracing of packets on loopback-interface

[Franz Edler]

Hi,

is there any possibility to trace packets on loopback-interface of my
WindowsXP machine.
I want to trace IP packets sent from one application to the other (using
different ports).

On Linux e.g. I can trace on "any" interfaces, but this I cannot with
Wireshark on Windows XP, right?

...and note that Windows doesn't have something equivalent to the
"loopback interface" in the UN*X sense - as far as I know, it handles
traffic from the sending machine to itself by wrapping it around
internally without it passing through a fake network interface, so there
*is* no loopback adapter on which to trace.

The Microsoft Loopback Adapter looks like a regular network adapter,
with a regular network interface, and traffic sent to a loopback
address, or to another of the machine's network interfaces, doesn't go
through it.
