I just realised that I cannot ping4 if I use /dev/tun0. I reverted my
configuration back to /dev/tap0. Following this, ping4 works again, so
I assume that tinc is connected.

I double checked and it seems fine. Because four eyes see more than two: :)

    A $ cat /usr/local/etc/tinc/hosts/B
	Address = B
	Subnet = fd16:dcc0:f4cc:0:0:2::/96
	Subnet = 10.2.0.0/16

	-----BEGIN RSA PUBLIC KEY-----
	<secret>
	-----END RSA PUBLIC KEY-----

The same file is on B.
