Build DHCP service on Linux system server, realize two basic functions: 1, automatically assign IP address, 2, specify IP address manually.First prepare two virtual machines as the experimental object, a Linux system as a server, a windows7 system as a client, both using the same virtual NIC Vmnet1, and using only host mode.Determine if the disc status on the server is connected,Use commands to view and Mou
