On each machine i used tcpdump -i <interfacename> ip6 Pve1 is source machine Pve2 is destination machine i see the ssh packet on pve1 dump i don't see the ssh packed from pve2 dump of course what i can't tell is 1. did the ssh packet hit the wire or not or got discarded by the driver= after tcpdumpsaw 2. if the packet did hit the wire did pve2 see it and discard the packet= before it got far enough up the stack to be seen by tcpdump... 3. and I am a little unclear how i could do that given this is a point t= o point connection of thunderbolt (i have seen classic IP so both a and b = above) pve1 root@pve1:~# cat pve1.tcpdump 11:55:49.665770 IP6 xxxx:xxxx:830:81::81 > xxxx:xxxx:830:81::82: ICMP6, ech= o request, id 19484, seq 1, length 64 11:55:49.666154 IP6 xxxx:xxxx:830:81::82 >
