The goal for Facter is to have these facts eventually namespaced, though we probably will have to keep existing fact names for backwards compatibility. That is to say, I want to be able to use:nic::wlan0::mac_address and nic::eth0::ip_address, etc. ipaddress itself is not so predictable either in a multi NIC setup, so being explicit is good.Even virtual machines can be dual homed. --Michael -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Er, you noted that you "fixed" this elsewhere, but... The 'macaddress' "fact" is a load of random garbage with no meaningful connection to reality: it picks a random address from the output of ifconfig, rather than anything useful. The idea of an "active" MAC is meaningless: my laptop currently has two "active" MAC addresses: 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.45 metric 1 192.168.201.0/24 dev wlan0 proto kernel scope link src 192.168.201.109 metric 2 169.254.0.0/16 dev eth0 scope link metric 1000 default via 192.168.1.1 dev eth0 proto static macaddress_eth0 => 00:1c:25:1e:26:6f macaddress_wlan0 => 00:1d:e0:55:48:45 There is no meaningful way to talk about one of those being "active" to the exclusion of the other: both are active, have real routes, and are interacting with external devices. You can even fail-over traffic between the two. The right fix would be to put that poor, meaningless fact to sleep before someone mistakes it for something actually *significant*.

Re: [Puppet Users] macaddress fact
I figured it out. It is an oversight in the macaddress.rb file for facter. I've already fixed it on my computer and I will open a bug to have it fixed. This only affects darwin nodes. --- Thanks, Allan Marcus 505-667-5666 On Apr 29, 2010, at 11:46 AM, Marcus, Allan B wrote: > How does puppet determine the macaccess fact?
