本文介绍如何通过编辑/etc/network/interfaces文件手动更改网卡的MAC地址。操作包括使用sudo权限编辑配置文件，找到对应网络接口（通常是eth0），在dhcp配置下添加新的MAC地址，并重启网络服务使更改生效。

There are a lot of reasons you might want to manually set your MAC address for your network card. I won't ask you what your reason is.

To change this setting, we'll need to edit the /etc/network/interfaces file. You can choose to use a different editor if you'd like.

sudo gedit /etc/network/interfaces

You should see the line for your network interface, which is usually eth0. If you have dhcp enabled, it will look like this:

auto eth0
iface eth0 inet dhcp

Just add another line below it to make it look something like this:

auto eth0
iface eth0 inet dhcp
hwaddress ether 01:02:03:04:05:06

Obviously you would want to choose something else for the MAC address, but it needs to be in the same format.

sudo /etc/init.d/networking restart

You will need to restart networking or reboot to take effect.
