没有subnet6声明用于eth0

Question

当我试图启动dhcp6服务器时，我总是在syslog中得到这个错误。我使用的命令是。

sudo service isc-dhcp-server restart

我得到的错误是：

No subnet6 declaration for eth0 (fd30::1:ff4e:3e:0:2c).

我的ifconfig是：

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.115.43  netmask 255.255.252.0  broadcast 192.168.115.255

我的dhcpd6.conf如下所示。

Answer 1

inet6 fd30::1:400b:3ffd:a32e:6c3c  prefixlen 64  scopeid 0x0<global>

您在分配给接口的fd30:0:0:1::/64子网中有一个ip，并且您似乎没有用于该/64的subnet6
