This article is reproduced, describes how Ubuntu set up IP and network to connect to the networkIf you are using Ubuntu in a virtual machine, please refer to my previous article virtual machine net to set up the Network Settings section of the extranet, first set up the host network, and then configure the virtual machine Ubuntu IP and gatewayIf the host operating system is Ubuntu, please directly refer to

So what is the gateway? A gateway is essentially a network that leads to its IP address. For example, if Network A and Network B exist, the IP address range of Network A is "192.168.1.1 ~ 192. 168.1.254 ", The subnet mask is 255.255.255.0, And the IP address range of Network

IP address from the NIC to static, This field specifies the IP address of the NIC. IPV6INIT = no IPV6_AUTOCONF = no NETMASK = 255.255.255.0 # network mask corresponding to the network adapter NETWORK = 192.168.1.0 # NETWORK address of the NIC ONBOOT = yes # whether to set this network interface when the system starts. if it is set to yes, the device is activated when the system starts. II. CentOS

1. Check if connectivity is possible, ping the gateway using the ping commandThe beginning is always real unreachable2. Set IPsudo ifconfig eth0 133.133.133.190 netmask 255.255.255.0This sets the IP address and subnet mask of the NIC Eth03. Set the gateway sudo route add default GW 133.133.133.404. Ping the gateway to

Telecom address. Otherwise, you can only ping the China Unicom address. If both China Unicom and China Telecom addresses are configured, the two cannot be connected. Because it is not our company's network, we are not clear about the Upper-layer implementation method. We only know that China Unicom and China Telecom lead to different VLANs, and China Telecom and China Unicom cannot pass through, however, other machines with the same intervention method can work normally out of the internet, so
