我正在尝试为设置虚拟 IP 。但配置后，当我尝试查看配置时，ucarp发生了一些奇怪的事情。我像这样更改ifup ifdown/etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
# The primary network interface
auto enp0s3
iface enp0s3 inet static
address 10.1.178.153
netmask 255.255.255.0
gateway 10.1.178.1
dns-nameservers 10.1.171.200
#######################
# ucarp configuration
#######################
# vid : The ID of the virtual server [1-255]

iface enp0s3:ucarp inet static
address 10.1.178.150
netmask 255.255.255.0
gateway 10.1.178.1
dns-nameservers 10.1.171.200
以下是此后终端程序的输出
$ sudo service networking restart
$ ifconfig

我尝试取enp0s3下来以便enp0s3:ucarp可以取上去，但是有一个惊喜＃1
$ sudo ifdown enp0s3
RTNETLINK answers: No such process
$ ifconfig

好吧，现在enp0s3我尝试提起的那个没有出现enp0s3:ucarp。但是出现了惊喜＃2
$ sudo ifup enp0s3:ucarp
RTNETLINK answers: File exists

Failed to bring up enp0s3:ucarp.

无法理解；无法配置ucarp；请求某人帮助我获得一些内心的平静！！
- 是否
ifconfig显示活动网络配置/所有网络配置，无论启动/关闭？ - 如何建立虚拟地址导致主接口也启动？
答案1
/run/network/ifstate没关系，Ubuntu 15.10 的更新似乎已经解决了这个问题。此外，还学会了交叉验证每个操作。
