1. Click the wired network card in the listing, then click the Edit button.
If the workstation has more than one wired network card, Ubuntu names
the cards in numerical order, starting at eth0 for the first card, eth1 for
the second card, and so on.
The Editing dialog box, shown in Figure 8-7, appears.

2. Configure the wired network card settings.
The Editing dialog box contains three tabs of information for the network
card:
• Wired: Sets the Media Access Control (MAC) address for the card
(which Ubuntu automatically detects) and the Media Transfer Unit
(MTU) size, set for automatic.
• 802.1x Security: Sets login details for connecting to a protected
wired network. Some network switches use this feature to restrict
access to a wired network. If your network uses 802.1x security,
consult your network administrator for the proper settings to use.
• IPv4 Settings: Determines how the IP address for the network card
is set. This can be either dynamically from a DHCP server, using
the zeroconf protocol to negotiate an address with other devices
on the network, or statically using a configured IP address.
