B2D 伺服器 IPv6網卡設定！

學校伺服器網卡設定：

# vi /etc/network/interfaces

auto lo eth0

iface lo inet loopback

iface eth0 inet static

address 163.27.210.1

netmask 255.255.255.192

network 163.27.210.0

broadcast 163.27.210.63

gateway 163.27.210.62

iface eth0 inet6 static

address 2001:288:6200:217::1

netmask 64

up /sbin/ifconfig eth0 inet6 add 2001:288:6200:217::1 || true

重啟網卡，不知為何不成功？IPv6果然難搞。
我覺得我DNS設定應該沒錯，也經過再三dig的確認。靈機一動，下指令查網卡的設定：

# ifconfig

eth0  Link encap:Ethernet HWaddr 00:0E:2E:F0:BB:F2

        inet addr:163.27.210.1 Bcast:163.27.210.63 Mask:255.255.255.192

        inet6 addr: 2001:288:6200:217:20e:2eff:fef0:bbf2/64 Scope:Global

        inet6 addr: fe80::20e:2eff:fef0:bbf2/64 Scope:Link

        UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

        RX packets:9527 errors:0 dropped:0 overruns:0 frame:0

        TX packets:8079 errors:0 dropped:0 overruns:0 carrier:0

        collisions:0 txqueuelen:1000

        RX bytes:1202385 (1.1 MiB) TX bytes:2113003 (2.0 MiB)

        Interrupt:18 Base address:0x2c00

lo    Link encap:Local Loopback

       inet addr:127.0.0.1 Mask:255.0.0.0

       inet6 addr: ::1/128 Scope:Host

       UP LOOPBACK RUNNING MTU:16436 Metric:1

       RX packets:2276 errors:0 dropped:0 overruns:0 frame:0

       TX packets:2276 errors:0 dropped:0 overruns:0 carrier:0

       collisions:0 txqueuelen:0

       RX bytes:244782 (239.0 KiB) TX bytes:244782 (239.0 KiB)

果然網卡的IPv6位址 2001:288:6200:217::1，並沒有被啟動！
這就是因為啟用 IPv6 功能後，因為auto-configuration，自動建立的 Link-local 位址。為
2001:288:6200:217:20e:2eff:fef0:bbf2/64

死馬當活馬醫，直接以指令設定：

# ip -6 addr add 2001:288:6200:217::1/64 dev eth0

但每次重開機都要下這個指令實在麻煩，把它寫進防火牆設定檔就好。

# vi  /etc/init.d/rc.local
貼上 ip -6 addr add 2001:288:6200:217::1/64 dev eth0 

哎，累啊！

還好有臥龍小三的IPv6文件：
