How to set a static IP in Ubuntu 14.04 server By default the Ubuntu 14.04 server sets the interface to use DHCP, here’s how to set a static IP address. Edit “/etc/network/interfaces”. In this example set-up we’ll use 192.168.1.50 as our server IP address: $sudo nano /etc/network/interfaces Find and comment the (default) DHCP entry. Your “interfaces” file should look like this: ——————————- # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 # DHCP not needed # iface eth0 inet dhcp iface eth0 inet static address 192.168.1.50 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 8.8.8.8 ——————————- Save and exit. $sudo nano /etc/resolv.conf Add: nameserver 192.168.1.1 nameserver 8.8.8.8 search mynetwork.local Save and exit. Edit /etc/hosts $sudo nano /etc/hosts Add: 192.168.1.50 u1404server.mynetwork.local u1404server Save and exit: Reload (start and stop) network $sudo ifdown eth0 && sudo ifup eth0 Note: There is a bug (feature?) in 14.04 where “service networking start|stop|restart” does nothing. This command/script worked in 13.10/13.04/12.04, however it doesn’t work in 14.04. To revert back to the 13.10 networking scripts go to: https://github.com/metral/restore_networking This will replace the 14.04 scripts with the one used in 13.10. $sudo apt-get install git $sudo git clone https://github.com/metral/restore_networking.git $cd restore_networking/ $sudo ./restore_networking.sh miguel@u1404server:~$ sudo service networking restart networking stop/waiting networking start/running
