I'm trying to use Ethereal to look at the packets going between LFS and an InSim program that I am working on. Unfortunately, I just found out that Ethereal doesn't support the loopback interface on Windows, so I can't look at local packets.

Is there a way around this? Is there a different packet analyzer that allows you to capture loopback connections?

When you say it doesn't support loopback on windows, do you mean just 127.0.0.1? If not, have you tried connecting to LFS via the public IP of your machine (if your on a LAN likely something like 192.168.0.x)

this might work, still for ethereal

Thanks for the replies. I ended up runing LFS on a different machine on the network and am looking at the traffic that way instead.
