Hi Ed, just as a side issue to this, because my ISP (I don't

about my VPN provider) IPv6 at all for anything, I was setting IPv6 to
'ignore' via Networkmanager in KDE (Gnome doesn't seem to have the
same options) but that was causing messages in the logs at boot time
about IPv6 not being ready. How do we stop the network from attempting
to activate IPv6 and then producing these messages when it has been
turned off?

I decided to do a test and add ipv6.disable=1 to the kernel parameter on one of my
VM's. In the past, this was sufficient. However, doing only this now results in
selinux errors. To avoid those you also need to add
"net.ipv6.conf.all.disable_ipv6 = 1" to /etc/sysctl.conf.

Remember that V6 is some option you do NOT have the option to ignore. And that strange
quirks could be solved by "net.ipv6.conf.all.disable_ipv6 = 1"
Some countries make haste implementing it, while others don't.
I was expecting that it would be countries like CN and CU where visitors would be
confronted with an IPv6-only situation.
However, last February I found out that our appliance didn't work, because of
IPv6-only. Here, in Europe, just some miles away in Belgium, Brussels.
So you better get your head out of the sand.
