138 Chapter 19. Network Configuration
By default, there is one profile called Common. To create a new profile, select Profile => New from
the pull-down menu, and enter a unique name for the profile.
You are now modifying the new profile as indicated by the status bar at the bottom of the main window.
Click on an existing device already in the list, and click the Copy button to copy the existing device
to a logical network device. If you use the New button, a network alias will be created, which is
incorrect. To change the properties of the logical device, select it from the list and click Edit. For
example, the nickname can be changed to a more descriptive name, such as eth0_office, so that
it can be recognized more easily.
In the list of devices, there is a column of checkboxes labeled Profile. For each profile, you can
check or uncheck devices. Only the checked devices are included for the currently selected profile.
For example, if you create a logical device named eth0_office in a profile called Office and
want to activate the logical device if the profile is selected, uncheck the device and check the
eth0
device.
eth0_office
For example, Figure 19-19 shows a profile called Office with the logical device eth0_office. It is
configured to activate the first Ethernet card using DHCP.
