Moving virtual machines from KVM to ESXi 6.0

Using OpenWRT to change Chromecast’s DNS resolvers

Chromecast may be smart and handy but annoyingly Google have decided to force it to use it’s own name servers as resolvers (which is a pain when the local resolver is configured to allow clients to use US Netflix, Hulu and the like). If you are running a OpenWRT based router, you are in luck Custom  In … Read more

iptables on a ChicagoVPS (OpenVZ) VPS
