using Sakura 6rd

      1. IPv6アドレスの算出 
        # printf "2001:e41:%02x%02x:%02x%02x::1\n" 59 106 69 124
2001:e41:3b6a:457c::1
      2. /etc/network/interfaces ファイルの編集 
        # vi /etc/network/interfaces   (以下を追加)
auto tun6rd
iface tun6rd inet6 v4tunnel
        address 2001:e41:3b6a:457c::1
        netmask 32
        local 59.106.69.124
        endpoint any
        gateway ::61.211.224.125
        ttl 64
        up ip tunnel 6rd dev tun6rd 6rd-prefix 2001:e41::/32
        up ip link set mtu 1280 dev tun6rd
      3. 設定反映を確認 
        # ifconfig tun6rd
tun6rd    Link encap:IPv6-in-IPv4
          inet6アドレス: ::59.106.69.124/128 範囲:Compat

another way

  • from ​さくらVPSのUbuntu 10.04でさくらの6rd（トライアル）を使う | Facebook
    • $ sudo cp /etc/apt/sources.list /etc/apt/sources.list.d/maverick.list
    • $ sudo sed -i s#lucid#maverick#g /etc/apt/sources.list.d/maverick.list
    • $ sudo vim /etc/apt/preferences.d/iproute-pin-600 
      Explanation: Do not install from maverick
Package: *
Pin: release n=maverick
Pin-Priority: -1

Explanation: Install iproute from maverick

Pin: release n=maverick
Pin-Priority: 600
    • これらに追加して、以下の設定が必要
  • /etc/apt/apt.conf.d/01ubuntu
  • これがないと、全てのパッケージがmaverickにupgradeされてしまう
    • $ aptitude -s safe-upgrade
