I installed OpenWrt on my router and I wanted to get MAC address of some machine connected to it.
With ipv4 I would use
arp command. But I want to resolve HW address knowing ipv6 addr. I have read that ipv6 has ndp protocol replacing arp and the command to lookup MAC table is
ip -6 neigh show, but the problem is BusyBox in my OpenWrt does not have
ip command and i am not sure if installing some package can bring it. So I wonder if there is any way to check MAC table for ipv6? Maybe I can just
cat some file?
Edit: I installed ip package with
opkg manager so now i can use
ip -6 neigh show, but I'm still wondering if I can get the same info using
