I gave it a go and I can add a route for 0.0.0.0 but unfortunately it doesnt result in ohai picking up the eth1 address, because I've still got a default route for eth0. Seems like 0.0.0.0 isn't quite the same as default in this respect.

Default route is the same with 0.0.0.0, you could try it instead.

This problem has been bothering me too.

I fixed it in my case by changing the default IP route to eth1 rather than eth0. In ubuntu, the command was:

sudo ip route change to default dev eth1 via [gateway ip]

I hoped I might do this in a recipe using the route resource, but:

route "default" do

  device "eth1"

end

Didn't recognize "default" as a valid address. Having looked at the doc and code it looks like the route resource only supports specific IP addresses.

Hello

Understood. It’s very helpful hint.

I will check the ohai output again and also custom plugin.

Thank you.

Maybe instead of relying on node[:ipaddress] you can rely on node[:network][:interfaces][:eth0][:addresses] hash. It has all the network info you may need. To get the IPv4 address you need to check for value of "family":

node[:network][:interfaces][:eth0][:addresses].each do |addr|

  if addr[:family] == "inet"

    return addr # not sure if this var contains actual value..

  end

end

Here's relevant section from ohai output:

Not to say you "can't", you just need to determine why ohai is setting
it the way it is and possibly replace the offending behavior. You
could add a new ohai plugin to modify the behavior, or potentially
submit a patch if it's a bug in ohai.
