Debian 7 上的 IPv6 连接断开

编辑：我根据搜索尝试了一些不同的方法。这是我的/etc/network/interfaces：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This line makes sure the interface will be brought up during boot
auto eth0
allow-hotplug eth0

# The primary network interface
iface eth0 inet static
    address 85.17.141.27
    netmask 255.255.255.0
    gateway 85.17.141.254
    # dns-* options are implemented by the resolvconf package, if installed
    dns-nameservers 85.17.150.123 85.17.96.69 85.17.150.123 62.212.64.122
    dns-search localdomain
    # up commands
    up ip addr add 85.17.141.33/24 dev eth0
    up ip -6 addr add 2001:1af8:4100:a00e:4::1/64 dev eth0
    up ip -6 ro add default via 2001:1af8:4100:a00e::1 dev eth0

然后ip addr show eth0输出：

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether d4:ae:52:c5:d2:1b brd ff:ff:ff:ff:ff:ff
inet 85.17.141.27/24 brd 85.17.141.255 scope global eth0
inet 85.17.141.33/24 scope global secondary eth0
inet6 2001:1af8:4100:a00e:d6ae:52ff:fec5:d21b/64 scope global dynamic 
   valid_lft 2591870sec preferred_lft 604670sec
inet6 2001:1af8:4100:a00e:4::1/64 scope global 
   valid_lft forever preferred_lft forever
inet6 fe80::d6ae:52ff:fec5:d21b/64 scope link 
   valid_lft forever preferred_lft forever

进一步ip -6 ro产出：

2001:1af8:4100:a00e::/64 dev eth0  proto kernel  metric 256 
fe80::/64 dev eth0  proto kernel  metric 256 
default via 2001:1af8:4100:a00e::1 dev eth0  metric 1024 
default via fe80::2d0:ff:fe9e:1800 dev eth0  proto kernel  metric 1024  expires 1627sec
default via fe80::2d0:2ff:fe33:3c00 dev eth0  proto kernel  metric 1024  expires 1627sec

最终，两个默认的原内核路由从输出中消失。不过，我的 IPv6 连接在夜间的某个时候仍然断开了。同样，只需运行一下，sudo service networking stop && sudo service networking start一切就恢复正常了。这两条fe80路由也重新出现了，这并不奇怪。有人有什么想法吗？

在旁边：任何 IPv4 连接都没有出现问题。

答案1

范围全局动态来自接口自动配置。前半部分与您的 IPv6 前缀相同，后半部分是 EUI-64（源自“FF:FE”和您的以太网 MAC 地址，除非您使用IPv6 隐私扩展）

如果你不想要它们，你可以通过以下方式禁用它们sysctl net.ipv6.conf.eth.autoconf = 0 前启动你的界面。

答案2

在 Debian 的文件中配置 IPv6 的正确方法/etc/network/interfaces是：

iface eth0 inet6 static
        address 2001:1af8:4100:a00e:4::1
        netmask 64
        gateway 2001:1af8:4100:a00e::1

您不应该有任何额外的up语句来配置您的 IPv6 地址。
