I know this is out there already in the Googlesphere, this post is more for me in the future than it is for you. I have a few Raspberry Pies and I like to run static IPs. It just makes things easier and I like having my network “all fancy”.
I went to setup a static IP the other day and it wasn’t working. I rebooted a few times until I figured out something was up. In my Googling I found out that the standard linux way of assigning a static IP address won’t work with the new version of Jessie for a Raspberry Pi. They made some updates and the old configuration now gets ignored. So editing the interfaces at /etc/network/interfaces is a no go. I mean you can, but it’s pointless. Not to worry the new way is just as easy as before it is just located in a different file now. Now you need to edit /etc/dhcpcd.conf, and the way you set the address is slightly different.
The old way of doing things:
iface lo inet loopback
iface eth0 inet static
dns-nameservers 220.127.116.11 18.104.22.168
iface wlan0 inet manual
iface default inet dhcp
And the new way of doing things:
static domain_name_servers=22.214.171.124 126.96.36.199
It has become a little easier if you ask me, you just need to know where the new file to edit is.
