Purpose of work: to get practical skills on work with ORACLE Virtual Box virtualization environment, on network configuration in Microsoft Windows and Linux operating systems, to get acquainted with command line utilities intended for diagnostics and configuration of a network, to develop executable files configuring a network interface by the set parameters, to get acquainted with a format of record of a way to a network resource UNC.

Necessary:

• ORACLE Virtual Box virtualization environment installed on your computer.
• Windows and Linux virtual hard disk images

1. Start virtual machine and log on to the system under administrator account using user name and password specified by teacher. Check whether the following items are active in the properties of the network connection being used:

   • Client for Microsoft networks
   • File and printer access service Microsoft
   • TCP/IP protocol.

   Determine the purpose of these components.

2. Set the following parameters in the properties of the TCP/IP protocol:

   • IP 192.168.1.10
   • mask 255.255.255.0
   • gateway 192.168.1.1
   • DNS 192.168.1.254

3. Using the knowledge gained in point 1, configure the network interface so that external users could not access computer resources.

4. To understand the assignment of parameters and keys of the following utilities:

   • ping
   • ipconfig
   • net with directives use, view, stop, start, share, config, session, user, statistics, localgroup

5. Use the netsh utility to create command files for the CMD.exe interpreter, which could be used to configure the selected network interface in two ways:

   • obtain all settings through a DHCP server (automatically) (IP, mask, gateway, DNS)
   • manual input of all settings (statically)

   Note: use the settings from point 2 as network settings.

6. This task can be done in PowerShell.

1. Start the virtual machine and log on to the system under an administrator account.

2. Know how to assign parameters and keys to the ifconfig utility.

3. Create an executable file that configures the selected network interface in two ways:

   • obtain all settings through a DHCP server (automatically) (IP, mask, gateway, DNS)

   • manual input of all settings (statically)

     Use the following data as static settings:

     IP 172.16.10.50
     Mask 255.255.0.0
     Gateway 172.16.0.1
     DNS 172.16.255.254
