Example Configuration
- Raspberry IP: 192.168.0.123
- Router IP (Gateway): 192.168.0.254
- Subnet Mask: 255.255.255.0
List the network interface we currently have available:
| cat /etc/network/interfaces |
The output should look like this:
|
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 |
The line iface eth0 inet dhcp shows that it is currently getting out IP address via DHCP. We need to change this line to iface eth0 inet static.
Edit /etc/network/interfaces
| sudo nano /etc/network/interfaces |
Change iface eth0 inet dhcp to iface eth0 inet static and add the following settings just below it:
|
address 192.168.0.123
netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.254 |
Here is an example:
|
auto lo iface lo inet loopback allow-hotplug wlan0 |
Finally, reboot the Raspberry Pi.
Fixing DNS problems
DNS is the service that converts the website URL, i.e. www.goggle.com into the IP address (173.194.126.36) that is needed for actual communication.
Check your DNS entrie
| cat /etc/resolv.conf |
Here is an example of the output
| nameserver 192.168.0.254 |
The nameserver should same as your gateway (your modem IP). If the nameserver and the gateway is different, you should modify the /etc/resolv.conf file and change the nameserver to your gateway IP.
| sudo nano /etc/resolv.conf |
