Solution to SIOCADDRT no such process on Ubuntu

Published: 22 Mar 2009

While configuring some Ubuntu servers to have a static IP address recently, I came across this error when I attempted to restart the network interfaces:

SIOCADDRT: no such process

I realized that I had invalid IP addresses for both my network and gateway entries in /etc/network/interfaces file:

# The primary network interface
auto eth0
iface eth0 inet static
  address 192.168.0.146
  netmask 255.255.255.0
  network 192.168.0.0
  broadcast 192.168.0.255
  gateway 192.168.0.1

Once you verify and correct the addresses, don’t forget to restart networking:

sudo /etc/init.d/networking restart
