passive_discovery6 [-Ds] [-m maxhop] [-R prefix] interface [script]
-D do also dump destination addresses (does not work with -m)
-s do only print the addresses, no other output
-m maxhop the maximum number of hops a target which is dumped may be away.
0 means local only, the maximum amount to make sense is usually 5
-R prefix exchange the defined prefix with the link local prefix
Passivly sniffs the network and dump all client's IPv6 addresses detected.
Note that in a switched environment you get better results when additionally
starting parasite6, however this will impact the network.
If a script name is specified after the interface, it is called with the
detected ipv6 address as first and the interface as second option.
