Hi,
I am using Linux-krogoth over IMX6

I want the ethernet interface 'eth0' to have static ip address
for that i edit the file 
vi /etc/network/interfaces   

# The primary network interface auto eth0 iface eth0 inet static     address 0.0.0.0     netmask 255.255.255.0

i changed dhcp to static

I added 
ifconfig eth0 0.0.0.0
to the startup script of linux (rc.local)

still i am getting a dhcp address at eth0 interface
if there is no dhcp server available in network i get 
169.254.x.x ip address 
if dhcp server is available ,it gets an dhcp ip address

What might be the issue , do i need to change in any other file to keep eth0 interface ip as static ?? 
Please resolve


Regards
Sameer

This is a reply in case a user get into this thread using the search.

Network configuration can be done through systemd.

To stop using DHCP and define a static ip address:

1. Create a configuration file  with desired parameters under /lib/systemd/network

# cat >> /lib/systemd/network/10-eth0.network << EOF
[Match]
Name=eth0
[Network]
Address=10.0.0.100/24
Gateway=10.0.0.1
EOF‍‍‍‍‍‍‍

2. Restart systemd-networkd service

# systemctl restart systemd-networkd.service

3. Verify

# ifconfig
eth0 Link encap:Ethernet HWaddr 00:04:9f:04:a7:48
 inet addr:10.0.0.100 Bcast:10.0.0.255 Mask:255.255.255.0
 inet6 addr: fe80::204:9fff:fe04:a748/64 Scope:Link
 UP BROADCAST RUNNING MULTICAST DYNAMIC MTU:1500 Metric:1
