linux - Ubuntu｜开机ifconfig没有eth0只有lo和无线，之前修改过/etc/network/interfaces 中的信息

Question

过程是这样的：

• 因为校园网客户端的原因，需要修改电脑的ＭＡＣ地址。

• 根据教程改了/etc/network/interfaces 中的信息：

原本是：

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

改成这样了：

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

＃试过下面这三行命令
#auto enp1s0   
#iface enp1s0 inet static
#hwaddress ether 30:65:EC:32:48:D3

＃也试过下面这两行命令
#auto enp1s0
#iface enp1s0 inet dhcp*

＃现在用的是这个
iface enp1s0 inet static
pre-up ifconfig enp1s0 hw ether 30:65:EC:32:48:D3

现在：

ifconfig -a

enp1s0    Link encap:Ethernet  HWaddr 40:8d:5c:a5:5c:c2  
          BROADCAST MULTICAST  MTU:1500  Metric:1

          RX bytes:2714584 (2.7 MB)  TX bytes:839383 (839.3 KB)

ifconfig 的话 没有最上面那个

＃怎么永久修改ＭＡＣ地址成 30:65:EC:32:48:D3 和解决上面的问题？

Answer 1

Ask and answer your own questions.
No command line is used, it is a graphical operation

System Setting in the upper right corner --> network -->Select the network card you are using (Wired) --> options -->Ethernet (Ethernet) -->Cloned MAC address: ::::(MAC address you want)-->Restart**　

I found a very powerful Ubuntu question and answer community AskＵbuntu.com. Basically, I can find answers to all the questions I encountered on it. Unfortunately, I found out about it too late.
