Testing Wayland on Fedora 21 Live CD

Wayland on Fedora21 Live CD

Gnome does not use Wayland by default when the Live CD boots up. To use Wayland, do the following:

  • set a password on the user account e.g. open terminal and issue passwd
  • log out of Gnome
  • below the login prompt should be a small cog icon, click that and select Gnome on Wayland from the dropdown menu
  • login

Docker IPv6

Docker IPv6

The scenario is where the ISP assigns a /104 IPv6 network 'on link' (i.e. not routed): xxxx:yyyy:1::9c3:0:0/104

Configure Linux host

Add the following to /etc/sysctl.conf:

# Accept Router Advertisements even if forwarding is enabled.
net.ipv6.conf.eth0.accept_ra = 2
