Question

我需要为本地计算机创建别名Ip，作为参考我使用https://websiteforstudents.com/switch-static-ip-address-ubuntu-17-04-17-10/

ifconfig将我的网络接口显示为：

wlp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.106  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::b7c0:76a:d0c0:3a7b  prefixlen 64  scopeid 0x20<link>
        ether 6c:71:d9:21:ff:61  txqueuelen 1000  (Ethernet)
        RX packets 389087  bytes 342937114 (342.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 270723  bytes 54566302 (54.5 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

但是当我按照参考文献中提到的那样运行sudo nano /etc/network/interfaces时，我看到了不同的文件内容：

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

所以我尝试手动将界面添加到/etc/network/interfaces：

# The primary network interface
auto wlp3s0
iface wlp3s0 inet dhcp

iface wlp3s0 inet static
address 10.254.254.254/24

但是当我正在运行sudo ifdown wlp3s0 && sudo ifup wlp3s0时，它无法正常工作：

ifdown: interface wlp3s0 not configured

我是新手，请帮我解决问题，谢谢！

别名的格式必须为 - wlp3sX：Y，其中X是物理网络接口编号，Y是网络接口编号别名。一切都在详细描述 - http://drach.pro/blog/linux/item/71-ip-address-alias-on-centos-6-6 http://semenushkin.ru/2010/09/28/ifconfig-alias/
