+The set up requires two VMs connected by a private network. With VirtualBox, this can be
+done by going under its "Preferences" menu and setting up a private NAT network.
-1. "Preference", then select the "Network" tab;
-2. Clicking on the "+" icon to create a new NAT network. A new entry will appear in the NAT networks list;
-3. Double clicking on the new network to edit its details, including giving int a name such as "RICNetwork";
-4. On the next page, make sure to check: "Enable Network", uncheck the "Supports DHCP" box, and make a note of the "Network CIDR" (for this example, it is 10.0.2.0/24);
-5. Click on the "Port Forwarding" button to create the following rules:
+#. Pick "Preferences", then select the "Network" tab;
+#. Click on the "+" icon to create a new NAT network. A new entry will appear in the NAT networks list
+#. Double click on the new network to edit its details; give it a name such as "RICNetwork"
+#. In the dialog, make sure to check the "Enable Network" box, uncheck the "Supports DHCP" box, and make a note of the "Network CIDR" (for this example, it is 10.0.2.0/24);
+#. Click on the "Port Forwarding" button then in the table create the following rules:
- 1. "ssh to ric", TCP, 127.0.0.1, 22222, 10.0.2.100, 22;
- 2. "ssh to aux", TCP, 127.0.0.1, 22223, 10.0.2.101, 22;
- 3. "entry to ric", TCP, 127.0.0.1, 22224, 10.0.2.100, 32080;
- 4. "entry to aux", TCP, 127.0.0.1, 22225, 10.0.2.101, 32080.
+ #. "ssh to ric", TCP, 127.0.0.1, 22222, 10.0.2.100, 22;
+ #. "ssh to aux", TCP, 127.0.0.1, 22223, 10.0.2.101, 22;
+ #. "entry to ric", TCP, 127.0.0.1, 22224, 10.0.2.100, 32080;
+ #. "entry to aux", TCP, 127.0.0.1, 22225, 10.0.2.101, 32080.
-6. "Ok" all the way back to create the network.
+#. Click "Ok" all the way back to create the network.
Creating VMs
--------------
+^^^^^^^^^^^^
Create a VirtualBox VM:
-1. "New", then enter the following in the pop-up: Name it for example **myric**, of "Linux" type, and at least 4G RAM and 10G disk;
-2. "Create" to create the VM. It will appear in the list of VMs.
-3. Highlight the new VM entry, right click on it, select "Settings".
+#. "New", then enter the following in the pop-up: Name it for example **myric**, of "Linux" type, and at least 6G RAM and 20G disk;
+#. "Create" to create the VM. It will appear in the list of VMs.
+#. Highlight the new VM entry, right click on it, select "Settings".
- 1. Under the "System" tab, then "Processor" tab, make sure to give the VM at least 2 vCPUs.
- 2. Under the "Storage" tab, point the CD to a Ubuntu 18.04 server ISO file;
- 3. Under the "Network" tab, then "Adapter 1" tab, make sure to:
+ #. Under the "System" tab, then "Processor" tab, make sure to give the VM at least 2 vCPUs.
+ #. Under the "Storage" tab, point the CD to a Ubuntu 18.04 server ISO file;
+ #. Under the "Network" tab, then "Adapter 1" tab, make sure to:
- 1. Check "Enable Network Adapter";
- 2. Attached to "NAT Network";
- 3. Network name for what was created in the previous section: "RICNetwork".
+ #. Check "Enable Network Adapter";
+ #. Attached to "NAT Network";
+ #. Select the Network that was created in the previous section: "RICNetwork".
Repeat the process and create the second VM named **myaux**.
Booting VM and OS Installation
-------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Follow the OS installation steps to install OS to the VM virtual disk media. Make sure to install openssh server.
+Follow the OS installation steps to install OS to the VM virtual disk media. During the setup you must
+configure static IP addresses as discussed next. And make sure to install openssh server.
VM Network Configuration
--------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^
-Depending on the version of the OS, the networking may be configured during the OS installation or after. The network interface is configured with static IP address:
+Depending on the version of the OS, the networking may be configured during the OS installation or after.
+The network interface is configured with a static IP address:
- IP Address: 10.0.2.100 for myric or 10.0.2.101 for myaux;
-- Network: 10.0.2.10/24, or network mask 255.255.255.0
+- Subnet 10.0.2.0/24, or network mask 255.255.255.0
- Default gateway: 10.0.2.1
-- Name server: 8.8.8.8
+- Name server: 8.8.8.8; if access to that is is blocked, configure a local DNS server
-Accessing the VMs
------------------
+Accessing the VMs
+^^^^^^^^^^^^^^^^^
-Because of the port forwarding configurations, the VMs are accessible from the VirtualBox host via ssh.

- To access **myric**: ssh {{USERNAME}}@127.0.0.1 -p 22222
- To access **myaux**: ssh {{USERNAME}}@127.0.0.1 -p 22223
