11.2.1 Information for Network Setting
In the Raspberry Pi system, the basic settings for the network are stored in "/etc/network/interfaces" file.
When you check the file contents on the Terminal screen, the following is included.
| pi@raspberrypi ~ $ pi@raspberrypi ~ $ cat /etc/network/interfaces |
| auto lo
iface lo inet loopback iface eth0 inet dhcp |
| allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp |
If you check after the system is installed at first, the contents as above are normally stored. It means loopback and Ethernet are installed.
If you have configured with the Wi-Fi configuration tool in the window, you may see the the contents below. This means that Wi-Fi is not automatically connected, but is operated either manually or according to the method specified in the Wi-Fi configuration tool.
