To setup LAN on the RaspberryPi it's quite easy, when just having plugged in the cable and using DHCP; there is usually no additional setup to. With
ifconfig you are able to see your current IP.
But if you want to setup a static IP, modify the “/etc/network/interfaces”:
auto lo iface lo inet loopback auto eth0 allow-hotplug eth0 #iface eth0 inet manual #iface eth0 inet dhcp iface eth0 inet static address 192.168.0.219 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.254 dns-nameservers 192.168.0.254 220.127.116.11 auto wlan0 allow-hotplug wlan0 iface wlan0 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf auto wlan1 allow-hotplug wlan1 iface wlan1 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp
Here we have an easy working setup in a class C network setup for eth0.
Within Debian aka Raspian “Jessie” some things changed slightly. A static address cannnot that easy be setup with the procedure above, which is also mentioned at top in
/etc/network/interfaces. There it's now written:
# 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 [...]
So you have to be aware to make additonal changes in
/etc/dhcpcd.conf, when trying to setup a static IP for
eth0. When staying with
interfaces, adding eth0 to the auto line should be the preferred way, as this might ensure, the IP setup is coming from interfaces.
For using this, find this row:
…and replace it with…
auto lo eth0
…or simply add a new row as in the former example setup above:
Network should work as setup before.
For using WiFi aka wlan0, just create an auto-entry or add
wlan0 in addition:
auto lo eth0 wlan0
When decided to use
/etc/dhcpcd.conf, at the end of the file the following rows need to be added to add an equal entry as the one from the setup at the top:
interface eth0 static ip_address=192.168.0.219/24 static routers=192.168.0.254 static domain_name_servers=192.168.0.254 18.104.22.168
