Looking for a network tool

[Uberwilhelm]

Hi all.

I am looking for something that I can use to sniff my network and show me everything that is attached. I have been googling but can't really seem to come up with what I am looking for. Any suggestions?

Spiceworks is one popular free one...although sluggish.

The Dude is another good one, free.

Network Magic another.

Outstanding. Many thanks. I tried Spiceworks and it seemed to work ok, but did not accomplish the goal I was after. I have three wireless APs that I can't find the docs for and have no idea what their IPs are. So I was hoping this would find them. Nope. LOL I confirmed they are active and working but still nothing. Any other suggestions other than going and resetting them?

how is the unknown AP connected to your sniffing PC?
crossovercable?
hub?
switch? - has to manageble to enable mirrorport!

have you tried packetyzer?
