Capturing packets from localhost on a windows system
Author
I''m debugging a network application on my windows machine, and because I don''t have a second machine handy, I need to go through the internal interface.
However, my current network sniffer, Ethereal, is unable to capture anything from the internal interface as this is apparently a limitation from Windows.
Are there any tools out there that will allow me to see what is going over the internal interface?
It would really help me a lot.
Thanks!
Just to make sure... Can you target your sniffer to check 127.0.0.1? That is the localhost address.

Nope, that''s the whole problem. Everything sent to the localhost address (127.0.0.1 as you mention) is not sent to a normally accessible network device in Windows. It''s handled internally, and can not be accessed through whatever API ordinary network sniffers use (I think, that''s what I read on the Ethereal forums).
I haven''t found a packet capture utility or device that works on Windows Loopback. if there is one, let me know. 
Also, Microsoft will automatically send a packet to the loopback if they see it for one of their local adapters. So you can''t target your local, non-loopback IP, it''ll still be send over the loopback adapter, so you won''t capture it.

Have you tried Packet Analyzer ?

sadly, I think it doesn't handle localhost ( I took the time to try it after posting )

Why not using your public ip (if you have one) instead of 127.0.0.1 if you have a direct conn to the net ?

I was browsing the Packet Analyzer website today(http://www.javvin.com/packet.html) and I found out that the version PRO support local host. Since I only have the trial "normal" version I can't verify this info
