Thanks for help from this gropup I can force the use of IPv4 by
running: sysctl -w net.ipv6.conf.all.disable_ipv6=1.
For a number of reasons I have just done a fresh install of Stretch,
hoping that the installer woould allow me to select IPv4, which, of
course it didn't.
Although I have been using Linux since the early days of Slackware, I am
not a hardware or OS person.
My question is how can I implement the sysctl statement on boot?
Thanks in advance.
