I already tried How do I set up networking/WiFi/Static IP but without success.

The IP address I would like to assign the pi would be 10.0.0.5. This worked well and at the time I am connected to it via SSH. But unfortunately I can not resolve any hostnames.

E.g. ping www.google.com results in unknown host but ping 8.8.8.8 works. I also cannot get any packages which is obvious because it cannot resolve the hostnames.

Below is my current /etc/network/interfaces file. The address, netmask and gateway are correct. I also disabled dhcpcd and enabled networking as mentioned in Network Interfaces method at the linked answer. I also tried the dhcpcd method but it is not working either. I am running Raspbian Jessie on it. 

# interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.0.0.5 netmask 255.255.255.0 gateway 10.0.0.138 allow-hotplug wlan0 iface wlan0 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf allow-hotplug wlan1 iface wlan1 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

I cannot find a way to get it working and I am hoping someone could help me to be able to resolve the hostnames again

  • You don't appear to have defined any dns servers Commented Aug 26, 2016 at 8:30
  • I had it in the config but it doesn't also if it is defined. Also Milliways said that it wouldn't be necessary to define one Commented Aug 26, 2016 at 8:33

    You probably HAVEN"T followed the tutorial (which still is sub-optimal). List the values you obtained in "Find the Settings of your local Network" Commented Aug 26, 2016 at 8:33

    No I said "this is generally not necessary", because this is often the same as gateway. Your gateway looks unusual. Also if you want to manually set IP you really need to understand what the settings mean. Commented Aug 26, 2016 at 8:36

You have not defined a DNS-server. You have to manually define that when you are setting a static IP in the /etc/network/interfaces file. If you instead have used to router (or DHCP-server) to assign an IP-address, defining a DNS-server would not be necessary.

Change the following lines:

auto eth0 iface eth0 inet static address 10.0.0.5 netmask 255.255.255.0 gateway 10.0.0.138

to

auto eth0 iface eth0 inet static address 10.0.0.5 netmask 255.255.255.0 gateway 10.0.0.138 dns-nameservers 8.8.8.8 8.8.4.4

where 8.8.8.8 and 8.8.4.4 is the DNS servers (in this case it is googles primary and secondary DNS)

  • Use 1.1.1.1 and 1.0.0.1 for CloudFlare DNS servers if you don't like Google (they're also 25% faster). Commented May 1, 2020 at 14:40
  • It was just an example, however - you should not give cloudflare your data either Commented May 5, 2020 at 6:17

You said:

I also tried the dhcpcd method but it is not working either

For anyone who uses this method (like me) by editing /etc/dhcpcd.conf, you should set the DNS servers accordingly:

interface eth0 # your static IP address: static ip_address=192.168.1.251/24 static routers=192.168.1.1 # CloudFlare DNS servers (faster than Google, and... it's not Google) static domain_name_servers=1.1.1.1 1.0.0.1

Reboot:

sudo reboot now

And confirm:

cat /etc/resolv.conf # Generated by resolvconf # nameserver 1.1.1.1 # nameserver 1.0.0.1

see this video for how to fix wifi instance on Rasbian Jessie 1.3.6 and OctoPi 0.14.0

https://www.youtube.com/watch?v=dZeJb6Jv-9E

From Wheezy to Jessie they changed the way that the wifi instance connects to router using a static ip address... (or something, Im not a developer...)
