1.	You can access details of services configured on your system from the Main Menu by choosing System Settings>Server Settings>Services.
2.	Use the ifconfig command with the -a option to determine the Ethernet address of the Ethernet card. Note that the Ethernet address is different from the IP address; the Ethernet address is the hardware address of the card and remains the same if you install the card on a different machine. The HWaddr field in the output of ifconfig displays the Ethernet address.
