Viewing Current Network Interface Settings
Type /sbin/ifconfig and press to display the status of the currently
active network interfaces.
The value of inet addr, in the eth0 group of statistics, is the currently
assigned IP Address of your DeTOS terminal. If DHCP was used, this is
the IP address that your terminal acquired during bootup. If you
configured static network settings, then this address should match the
value you entered in the IP Address field.
