First introduce the environment:1. The host computer's operating system is scientific Linux, kernel version 2.6.18, hostname spvm02,ip address 135.100.101.102, and VMware Workstation 8 deployed.2. Guest (virtual machine) This side of the installed operating system is windows 7.3. Guest uses the VMNET8 network card to achieve Internet access through the NAT protocol.The feature that needs to be implemented is that other computers in the host network us
