RedHat Linux network configuration (directly modify the configuration file instead of setup)
To create a Linux server, you must first understand the meaning of the configuration files related to network services in the Linux environment and how to configure security. In Linu
One: DHCP service validation1: Before we have installed the CentOS, we chose the network mode for the NAT mode, then how can we quickly implement virtual machine system access to the extranet? Can you go directly to the Internet, let's tryPing baidu.com2: Prompt unknown name or service, come to us to view the next IP, I have been using ifconfig, just see can use IP addr, we use IP addr tryIP addr3:ENS33 is our net

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission.
I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking m
After the virtual machine is installed, two NICs are added to the network connection:
Among them, vmnet1 is the network interface in the host-only mode of the virtual machine, and vmnet8 is the network interface in the NAT mode, which will be described in detail later.

(3) Bridge (VMNET0): Bridging mode, this is the need for us, to the virtual machine Mac OS assigned A and host the same IP address, and the host LAN other machines have the same principal status

Now some hosts have multiple NICs how to configure each NIC with a different IP address for the same network segment:1. Use Ifconfig to see how many network cards are available: I'm hosts are Nic:eth0 and Eth8.An IP has been configured on the eth0 now I need to configure the IP address on the ETH82. First check that the NIC is well connected: for example, if the light on the interface is shining, the line
