# This small utility will display all the informations about the network interfaces
# that one can use under Windows with modules using pcaprub and having the INTERFACE option (ex: arp_poisonning, arp_sweep, ...).
# To use th interface option under  Windows use the Index value displayed by this tool (ex: "SET INTERFACE 1")
