linux更改ip地址命令
It’s easy to change your IP address using a graphic interface, but did you know that Linux also lets you change your network card’s IP address using a simple command from the command line?
使用图形界面更改IP地址很容易，但是您是否知道Linux还允许您使用命令行中的简单命令来更改网卡的IP地址？
This trick should work on all Debian-based Linux distros, including Ubuntu. To get started, type ifconfig at the terminal prompt, and then hit Enter. This command lists all network interfaces on the system, so take note of the name of the interface for which you want to change the IP address.
这个技巧应该可以在所有基于DebianLinux发行版中使用，包括Ubuntu。 首先，在终端提示符下键入ifconfig ，然后按Enter。 该命令列出了系统上的所有网络接口，因此请记下要更改其IP地址的接口的名称。
To change the settings, you also use the ifconfig command, this time with a few additional parameters. The following command changes the network interface named “eth0” to use the IP address 102.168.0.1, and assigns the subnet mask 255.255.255.0:
要更改设置，您还可以使用ifconfig命令，这次使用一些附加参数。 以下命令将名为“ eth0”的网络接口更改为使用IP地址102.168.0.1，并分配子网掩码255.255.255.0：
sudo ifconfig eth0 192.168.0.1 netmask 255.255.255.0You could, of course, substitute in whatever values you want. If you run ifconfig again, you will see that your interface has now taken on the new settings you assigned to it.
当然，您可以用所需的任何值替代。 如果再次运行ifconfig，您将看到界面现在已经采用了分配给它的新设置。
If you also need to change the Default Gateway used by the network interface, you can use the route command. The following command, for example, sets the default gateway for the “eth0” interface to 192.168.0.253:
如果还需要更改网络接口使用的默认网关，则可以使用route命令。 例如，以下命令将“ eth0”接口的默认网关设置为192.168.0.253：
sudo route add default gw 192.168.0.253 eth0To see your new setting, you will need to display the routing table. Type the following command at the prompt, and then hit Enter:
要查看新设置，您需要显示路由表。 在提示符下键入以下命令，然后按Enter：
route -nThat’s all there is to changing your IP address from the terminal. If you’re interested in other great networking tools you can use at the terminal, be sure to check out our guide to the subject.
