I want to make my computer invisible or hidden to the other computers connected to the same wireless network. In other words, I want to turn off network visibility or network mapping.
I think this amounts to the ability to turn on and off the Windows Link-Layer Topology Discovery (LLTD) Responder. http://support.microsoft.com/kb/922120
On windows, I believe this would be comparable to setting the wireless network as Public instead of Home. I like to share files using Ubuntu when I am connected to my Home router, but I don't want to be discoverable or visible to clients on a public wifi network.
I have already created a shared folder on my desktop which installed some sort of networking components to interact with Windows, but I don't want the public wifi network to see this folder, or my computer name at all. I want to be invisible to other clients on the same network. Right now I am visible and can see other clients connected to this public wifi router.
(In case some ask: I do not want to disable SSID broadcasting on the router as it is a public wifi router that I do not have access to.)
Can anyone explain how to do this (preferably with a GUI method so I can reverse the steps when I connect to my Home network)?
