IPv6 with tunnelbroker.net, ChicagoVPS and Ubuntu
I have recently moved my hosting to a couple of VPSes at ChicagoVPS and wanted to use IPv6 tunnelbroker.net ChicagoVPS uses OpenVZ which presents a couple of problems $ ifconfig sit0 sit0: error fetching interface information: Device not found $ sudo modprobe ipv6 FATAL: Module ipv6 not found. It turns out, this is a fairly common problem though OpenVZ is supposed to support IPv6. Luckily, someone made a small userland program tb-tun, which “tunnels” IPv6 tunnels through a TUN/TAP device....
