Ubuntu is a popular open-source distribution of the Linux operating system. Often you need to transfer files from one computer to another but don't have a traditional network or external drive to use. In these instances, it can be practical to use a crossover cable to connect the two computers. A crossover cable is a specially wired network cable designed to network two computers without using routers, hubs or switches.

Power on the Ubuntu computer. If you prefer, plug cables into your computers while they are off. You may do this after Step 3 instead.
Connect one end of the crossover cable to the ethernet port on the network card in your Ubuntu computer. The ethernet port looks like an oversized phone jack usually located on the rear of your computer. On a laptop, it may be on the side instead.
Plug the other end of the crossover cable into the ethernet port of the other computer in the same manner as Step 1.
Right-click on the network manager icon in the upper right-hand corner of the desktop on the taskbar. Left-click on "Edit Connections" to bring up the Network Connections window.
Select the "Wired" tab and push the "Add" button. Name the connection in the "Connection Name" field. Uncheck the box that says "Connect automatically." Check the box to make it available to all users.
Click the "IPv4 Settings" tab and change the drop-down box that indicates the Method to "Manual." Press the "Add" button and add an IP address such as 192.168.2.24 under the "Address" column. This is the address you are assigning to your computer. Under the Netmask column, type "255.255.255.0" and press the "Enter" key. Click "Apply." Make sure the other computer is using the same IP address scheme as your Ubuntu computer. In this example, it should be 192.168.2.x with "x" being a different number than 24. The netmask for it should also be 255.255.255.0.
Enter the administrative password when you are prompted to authorise the changes. Close the Network Connections window.
Left-click on the network connections icon in the taskbar and click the name of the connection you just created from the list. Your crossover connection is now set up.
Tips and warnings
- If you are using the other computer as an Internet gateway for your Ubuntu computer, use the network scheme set-up already on that computer, and enter that computer's gateway address as well on your Ubuntu computer.
