Does anyone have a reference on how to write them - the reductive labs docs seem a little broken today. Or better still, has someone already written such a thing :)
As a matter of fact, yes, I have. :-) In my "nsc-puppet-utils" module, I have a function resolve_ipnets() which does that. (It does have some additional features as well. For example, it resolves names on the form "foo.example.com/24" to "10.20.30.17/24", and it handles lists of hostnames as well.) Do a 'git clone http://www.nsc.liu.se/~bellman/nsc-puppet-utils.git' to get my module. There is documentation inside the file plugins/puppet/parser/functions/resolve_ipnets.rb. A little note, though. If you use this to populate /etc/hosts from DNS, and you do so on your Puppetmaster, you won't be able to change the address of that name. The next time resolve_ipnets() is called, it will find the address in /etc/hosts, and then you're stuck. (You can of course remove that entry from /etc/hosts manually, and then you'll be OK again, but that's cheating. :-) /Bellman -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
