我想用 alpine 创建一个 dhcp6 服务器
我正在使用 Kea-dhcp6。我的文件配置如下：
{
# DHCPv6 configuration starts on the next line
"Dhcp6": {
# First we set up global values
"valid-lifetime": 4000,
"renew-timer": 1000,
"rebind-timer": 2000,
"preferred-lifetime": 3000,
# Next we set up the interfaces to be used by the server.
"interfaces-config": {
"interfaces": [ "eth0" ]
},
# And we specify the type of lease database
"lease-database": {
"type": "memfile",
"persist": true,
"name": "/var/lib/kea/dhcp6.leases",
"lfc-interval": 1800,
"max-row-errors": 100
},
"preferred-lifetime": 3000,
"valid-lifetime": 4000,
"renew-timer": 1000,
"rebind-timer": 2000,
# Finally, we list the subnets from which we will be leasing addresses.
"subnet6": [
{
"subnet": "3003::0/112",
"pools": [
{
"pool": "3003::20-3003::ffff"
}
]
}
],
"reservations": [
{
"hw-address": "00:0c:29:60:f8:3d",
"ip-addresses": [ "3003::101" ]
}
]
# DHCPv6 configuration ends with the next line
}
}
它正在运行，但 MAC 地址为“00：0c：29：60：f8：3d”的虚拟机返回此错误：
udhcpc6: started, v1.32.1
udhcpc6: sending discover
udhcpc6: sending select
udhcpc6: no IAADDR option, ignoring packet
udhcpc6: sending select
udhcpc6: no IAADDR option, ignoring packet

udhcpc6: sending select
udhcpc6: no IAADDR option, ignoring packet
udhcpc6: sending select
udhcpc6: no IAADDR option, ignoring packet
udhcpc failed to get a DHCP lease
有人能帮我吗 ？？？
我运行了这个命令：
kea-dhcp6 -d -t /etc/kea/kea-dhcp6.conf
其回报为：

它似乎有效，但客户端没有收到任何 IP
请帮帮我
我将 conf 文件更改为：

# DHCPv6 configuration ends with the next line
}
}
当我在 Alpine VM 客户端中运行 udhcpc6 时，它的返回结果是
udhcpc6: started, v1.32.1
udhcpc6: sending discover
udhcpc6: sending select
udhcpc6: IPv6 obtained, lease time 4000
但如果我运行 ifconfig 我看不到任何 IP
解决方案？？
答案1
是的，Alpine 没有从我的路由器获取 IPv6，我只运行 DHCPv6 来提供 IPv6 IP。
通过安装 dhcpcd 我能够使其工作。apk add dhcpcd
