[chef] How to get an array of all IP addresses on a node?

[Chaim Keren-Tzion < >]

I've been using the following to get an array of all IP addresses on a node:

node.network.interfaces.map { |p, f| f[:addresses].keys }.flatten

Which I then clean up with the following to get rid of the mac addresses:

node.network.interfaces.map { |p, f| f[:addresses].keys }.flatten.delete_if{|x| x =~ /(.*):(.*)/ }

It works on CentOS 5 hosts and vserver guests on CentOS 5 hosts however it does not work on KVM guests or on RedHat 4 hosts. The output on those nodes is different so they can't use the "keys" method.

Anyone know of any reliable and consistent ways to get a list of all IP Addresses on a node?

Thanks,

Chaim
