networking.service 無法啟動 eth0:2 和 eth0:3,但我的設定似乎是正確的。
我嘗試了幾件事,還將網路卡從 ens3 重命名為 eth0
/etc/網路/介面:
auto lo
iface lo inet loopback
allow-hotplug eth0
auto eth0
iface eth0 inet static
address xx.xxx.xxx.xxx/22
gateway xx.xxx.xxx.x
allow-hotplug eth0:1
auto eth0:1
iface eth0:1 inet6 static
address 2a03:xxxx:x:xxxx::1000/64
gateway fe80::1
allow-hotplug eth0:2
iface eth0:2 inet6 static
address 2a03:xxxx:x:xxxx::2000/64
gateway fe80::1
allow-hotplug eth0:3
iface eth0:3 inet6 static
address 2a03:xxxx:x:xxxx::3000/64
gateway fe80::1
預期的:
啟動時,eth0 和 eth0:1 會自動啟動。
ifup eth0:2 和 ifup eth0:3 調出其他網路卡
實際的:
ifup eth0:2
RTNETLINK answers: File exists
ifup: failed to bring up eth0:2
ifup eth0:3
RTNETLINK answers: File exists
ifup: failed to bring up eth0:3
它給出了錯誤,但儘管出現錯誤,適配器仍已加載並且 IPv6 正在工作。
另外,如果我添加
自動 eth0:2
自動 eth0:3
Networking.service 啟動失敗:

儘管網路服務失敗,但所有 IPv6 都正常運作。
我不知道出了什麼問題。
答案1
您嘗試eth0:x
對 IPv6 使用過時的介面別名格式 ( ),但這不起作用。這些實際上並不是獨立的接口,而且從來都不是。十多年來也一直建議不要使用它們。你不應該這樣做。 (並且您應該忽略 Debian wiki 中關於此方法的長期過時警告。)
正確的配置是將所有位址放在介面中eth0
(或者更確切地說,ens3
因為它不應該再這樣了eth0
)。
