sit0 is used for ipv6 tunneling (6to4), it is not a physical interface While you're in the Ubuntu environment, issue "lspci -k" to see which kernel driver your ethernet device uses. It is R8169 which is provided by: Symbol: R8169 [=y] Type : tristate Prompt: Realtek 8169 gigabit ethernet support Location: -> Device Drivers -> Network device support (NETDEVICES [=y]) -> Ethernet driver support (ETHERNET [=y]) -> Realtek devices (NET_VENDOR_REALTEK [=y]) The Gentoo Handbook has the following Networking section http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=8#doc_chap2 which tells you what to do.
