I fear there is no difference above the transport layer. For wireless cards, you can tell the difference by inspecting the card itself. For devices, that are connected to normal ethernet card via TP, the computer has no way to tell, because the device behaves like a repeating HUB or switch. Some devices use a different link layer (eg. X.25 or may be PPP), so you can tell from te device configuration. But the IP layer never makes any difference, so you can't tell from remote machine unless one endpoint of the connection is willing to tell you. Why do you need to make such a distinction? ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
