Re: Capturing packets on 'loopback' on Win7?

[Jeffrey Schmidt <schmidtj () seapine com>]

Martin,

   Well, thanks for the suggestion – I appreciate that you’re trying to help. Unfortunately, that wiki article you 
originally linked in your first reply, has the following to say:

“This adapter is a virtual network adapter you can add, but it will not work on the 127.0.0.1 IP addresses; it will 
take its own IP address.”

Well, I’ll keep hunting. I’ve actually moved to working on a different project, but I’ll probably come back to this 
eventually. Perhaps not – the problem I was trying to debug seems to have fixed itself (man I hate when that happens, 
because it means I never figured out the source to begin with, and it might come right back and bite me later, but as 
long as it’s not happening, it’s hard to debug).

Jeff,

To be honest not an expert on this, but my assumption would be that the loopback adapter needs to have 
127.0.0.0/8<http://127.0.0.0/8> address, which is the loopback address range. Maybe that is your problem.

Hello,

   I tried installing the MS Loopback adapter, and assigning it an address. I can successfully access the web server on 
the machine using the local address (10.0.10.1). I tried using Wireshark to capture packets on that adapter, but none 
of the SOAP traffic I’m trying to capture is actually showing up in Wireshark. Any ideas?

Hello,

   Is it possible to start a capture on the loopback interface on Windows 7? I have a client and server both running on 
the same machine which I’ve Installed Wireshark on. However, it appears that I cannot capture that ‘local’ traffic – 
only packets sent and received by the physical Ethernet device on my computer?
