ubuntu 配置ip地址命令（Ubuntu配置IP地址命令） Ubuntu configure the IP address command The IP command line is configured as follows Sudo GEDIT /etc/network/interfaces DHCP The DHCP configuration is as follows (assuming Internet access via eth1) # The primary network interface DHCP to find our address - use Auto eth1 Iface eth1 INET DHCP / / designated as DHCP Then restart Sudo /etc/init.d/networking restart Static IP Static IP address configuration is as follows (assuming the Internet through eth1 The primary network interface #) Auto eth1 Iface eth1 INET static / / designated as static Address 192.168.3.90 //IP address Gateway / 192.168.3.1 gateway Netmask 255.255.255.0 / subnet mask Also need to restart Sudo /etc/init.d/networking restart DNS Configure DNS if necessary Sudo GEDIT /etc/resolv.conf Nameserver 192.168.3.2 In addition, a detailed explanation is given: The network parameters of the Ubuntu are stored in the file /etc/network/interfaces, and the default setting uses DHCP, which reads as follows: The primary network interface # Auto eth0 Iface eth0 INET DHCP The method for setting static IP is as follows: 1) edit /etc/network/interfaces 1.1) shielding the DHCP line The primary network interface # Auto eth0 #iface eth0 INET DHCP 1.2) add parameters related to static IP The primary network interface # Iface eth0 INET static Address 192.168.0.10 Netmask 255.255.255.0 Gateway 192.168.0.1 2) edit /etc/resolv.conf, set DNS Nameserver 202.96.134.133 Nameserver 202.106.0.20 3) execute the following two commands to enable the new settings $sudo ifdown eth0 $sudo ifup eth0 Ifconfig Whether the Linux is installed automatically or we manually install it, Linux asks you questions about the network and configures the software. This is for configuration The basic command of the network card is ifconfig. After the ifconfig command is executed, the system will set the necessary parameters in the kernel table so that Linux knows How to communicate with the network card on the network. Th
