online杜甫在ubuntu配置IPV6

skyboy

杜甫上运行的是ubuntu 16.04，正在尝试给机子配置IPV6，希望每次启动后自动获取IPV6

按online官网的配置试了，reboot 后会卡在下图那里10分钟才能完全起来，而且不能获取ipv6地址

online官网配置如下：

/etc/dhcp/dhclient6.conf :

interface "eno1" {
   send dhcp6.client-id DUID;
}

etc/network/interfaces comme suit :

iface eno1 inet6 static
    pre-up modprobe ipv6
    pre-up dhclient -cf /etc/dhcp/dhclient6.conf -6 -P -d -v eno1
    address IPV6ADDRESS
    netmask PREFIXLEN

然后我从我晚上搜索了一下，被配置改了下，一次启动后成功了，但过了2天，机子重启后，又出现楼上的哪种现象。

The relevant /etc/network/interfaces part:

# The primary network interface
auto eno1
iface eno1 inet dhcp
iface eno1 inet6 static
        address 2001:bc8:xxxx:xxxx::1
        netmask 56
        autoconf 0
        pre-up /sbin/dhclient -cf /etc/dhcp/dhclient6.conf -6 -P eno1
        pre-down /sbin/dhclient -x -pf /var/run/dhclient6.pid

Created by hand this /etc/dhcp/dhclient6.conf file:
# For Online.net dedibox IPv6 subnet
interface "eno1" {
        send dhcp6.client-id DUID
        request;
} (use whatever DUID your personal IPv6 subnet has, find it in Online's console)

标记下，online ipv6

原因找到了，是ufw把IPV6 DHCP的端口给封了

现在按online官网进行配置进行修改可成功运行，配置如下

/etc/dhcp/dhclient6.conf :

interface "eno1" {
   send dhcp6.client-id DUID;
}

etc/network/interfaces comme suit :

iface eno1 inet6 static
    pre-up modprobe ipv6
    pre-up dhclient -cf /etc/dhcp/dhclient6.conf -6 -P -v eno1 (这里记得把官网的-d参数去掉）
    address IPV6ADDRESS
    netmask PREFIXLEN
