[yocto] how to set static ip in linux

[Constantin, Costin C]

... or easier, you can directly use the poky_dir/meta/recipes-core/init-ifupdown/init-ifupdown-1.0/interfaces to
set up interfaces. An eg. would be:

auto eth0
iface eth0 inet static
        address 192.168.1.100
        netmask 255.255.255.0
        network 192.168.1.0
        gateway 192.168.1.1

I personally used the already mentioned method for convenience, because i had a lot to work with install script
lately ...

I'd install a custom /etc/network/interfaces file via a bbappend or
similar method. There is numerous examples in google of how to set up  a
static Ip via the interfaces file.
