Re: how to prefer temporary address? (raspbian / stretch)

At the moment my raspy (stretch-based Raspbian) is getting a /128 static
lease from my router out of the /48 I get from the he.net tunnel.
It also has a /64 address which seems stable across reboots but is not a
slaac address.
It would be clearer if you posted the output of
ip -6 addr
If you have privacy concerns feel free to mangle the /48 prefix assigned
by the tunnel broker.
Where does this /64 address come from? In the logs I see it mentioned by
avahi-daemon and dhcpd but I cannot find a corresponding lease file.
dhcpd (ISC DHCP server) or dhcpcd (DHCP client daemon) ?
More important, how do I get the sytem to generate and prefer a
temporary address for outgoing connections?
sysctl net.ipv6.conf.${INTERFACE}.use_tempaddr=2
How to set it at the system configuration level depends on the network
configuration framework used. With ifupdown, add the following option to
the iface stanza in /etc/network/interfaces :
privext 2
