1. Create a network session instance
View network information and network status
nmcli connection show
Using con-name parameter specifies the name of the company's network
nmcli connection add con-name company ifname ens33 autoconnect no type 192.168.10.1/24 gw4 192.168.10.1
Using con-name parameter specifies the name of the network session for home use home there is no need to manually specify
nmcli connection add con-name home type ethernet ifname ens33
After successfully creating a network session "can be used to create nmcli command to view all network sessions
nmcli connection show
Use nmcli command-configured network session is permanent, so when we get home from work smoothly start the home network session, the card will be able to obtain the IP address through DHCP
nmcli connection up home
If a virtual machine is requested to switch the system into a virtual network card bridged mode
Session Initiation company to stop home session
nmcli connection down home
nmcli connection up company
ifconfig
If you want to delete the session, execute nmcli command execution E map ah connection command, and then you want to delete the session can be stand-alone Deler
2. Bind two network cards
LAN equipment in the same mode, you can bind the network card, otherwise the two network cards can not Hu Chuan data
Use a text editor vim configuration of LAN equipment specified parameters
vim /etc/sysconfig/network-scripts/ifcfg-eds33
vim /etc/sysconfig/network-scripts/ifcfg-eds38
The equipment also need to be named after binding bond0 and write into IP addresses
vim /etc/sysconfig/network-scripts/ifcfg-bond0
Let Linux kernel support NIC teaming drivers. Common NIC teaming drivers are 3 modes --mode0, mode1, mode6
mode6: usually two network cards are working, and automatic backup, no need to switch to provide ancillary support equipment
Create a file for the NIC driver binding using a text editor vim
vim /etc/modprobe.d/bond.conf
3. Configure sshd service
sshd is capable of providing remote access protocol in a secure way, it is now the preferred way to remotely manage Linux systems
