In Jessie (and other systemd OS's?), static IP and DNS have moved to /etc/dhcpd.conf. All I did to setup this machine was to add the following to the bottom of dhcpd.conf: interface eth0 static ip_address=192.168.0.8/24 static routers=192.168.0.1 static domain_name_servers=220.127.116.11 18.104.22.168 ...I hadn't tried "service networking restart", which generates a warning. While networking was fine at this point, I ran the suggested command which had no visible affect (networking still fine).
