Answer 1

You only have LL addresses, what are you going to scan? Let me explain, you do not have a normal ipv6 network and addressing on the interface.

Answer 2

If ff02::1%ifname does not respond to ping6, then scanning the IPv6 network is problematic. If the switch used EUI-64, then you can generate a link-local address from the MAC ( calc ). Well, or as a last resort, when enabled, it should send ICMPv6 notifications to prevent possible address conflicts, and this notification can be caught by a sniffer.

Answer 3

var x = "hello";
var arr = x.split('')

Answer 4

In some places mixed up the source and receiver.
x[i] = z[i];
=>
z[i] = x[i];
