2. Experimental content
1. Vmware virtual machine software installation;
2. NAT network to realize Linux Internet access
3. SSH terminal login software SecureCRT installation
4. SecureCRT through SSH protocol to log in to the Linux system from other hosts
5. Use winscp to realize file transfer between hosts
6 、Close the Vmware Linux virtual machine correctly
Three, experimental steps
1. Vmware virtual machine software installation
Configure the virtual machine (virtual machine -> settings): memory is 1G, processor is 2 and display resolution is 1024 * 768.
After configuration, the status of the virtual machine is: shut down.
2. NAT network realizes Linux Internet access
Virtual machine -> Settings, select NAT mode 
Click to open this virtual machine, the user name is root, and the initial password is 123456.
If the following figure is displayed, the login is successful.

following figure will be displayed if the login is successful
4. Use SecureCRT to log in to Linux via SSH
5. Use winscp to realize file transfer between hosts.
Upload a picture "13.3.jpg" on your computer to the virtual machine under "/root/desktop" through winscp
Open the root folder on the virtual machine desktop, find the picture '13.3.jpg', the file transfer is successful
6. Shut down the Vmware Linux virtual machine correctly.
Enter the'shutdown -h now' command in the terminal of the virtual machine
The status of the virtual machine is shown in the following figure: Shut down
