Chapter 13. Appendix 6 – I.P. address configuration on PC or Laptop

With APIPA (Automatic Private I.P. Addressing), a laptop or PC can automatically configure itself with an I.P. address in the range 169.254.0.1 to 169.254.255.254. The default subnet mask is 255.255.0.0.

Connect the Minimus to the laptop or PC using the blue Ethernet cable and power it up.

13.1 On Linux

On your Linux computer, open the terminal and type the command

sudo bash

Key and provide the appropriate password. Then, enter the command

ifconfig

to identify the Ethernet network interface to which the Minimus is connected. Once you have identified the correct interface, connect the Minimus, power it up and enter the commands

ifconfig wlp2s0 down

ifconfig wlp2s0 up

replacing wlp2s0 with the name of the appropriate interface on your PC.

Enter the command ifconfig again to verify that the IPv4 address of the Ethernet adapter is now included in the network 169.254.0.0/16 - i.e. the address begins 169.154.…

In the example above, the interface has been allocated address 169.254.139.29, which is in the correct network.

13.2 On macOS

Click the Apple icon in the upper-left corner of the screen, and select "System Preferences."

• Click the "Network" icon to open the Network Preferences pane and select "Ethernet" from the list on the left side of the window.

  

• Click the gear button, , in the lower-left corner of the window, then click "Make Service Inactive." Click the "Apply" button to disable the NIC (Network Interface Card).

• With the Minimus connected and powered up, click the button again, click "Make Service Active" and click "Apply" to re-enable the NIC.

• Check that the interface has been assigned an address in the correct network:

  

  In the example above, the interface has been allocated address 169.254.56.230, which is in the correct network.

13.3 On Windows

On a Windows computer, key + to open the "Run" dialogue, enter ncpa.cpl and key .

Right-click on the network adapter which is connected to the Minimus and select “Disable” from the context menu. Right-click on the same adapter again and select “Enable”. Close the network settings window.

Key + and type cmd., then . This opens a command window. Type the command ipconfig and verify that the IPv4 address of the Ethernet adapter is included in network 169.254.*.*.

In the example above, the interface has been allocated address 169.254.56.230, which is in the correct network.
