Ok, fair enough but it would solve a part of the problem without preventing other parts from being solved, right? I'm trying to fight the feeling I have that we're all aiming for a solution that's just a bit too perfect. ---------------------------------------- Feature #7559: Fact for identifying Amazon VPC instances. https://projects.puppetlabs.com/issues/7559#change-78404 Author: Nigel Kersten Status: Accepted Priority: Normal Assignee: Category: library Target version: Keywords: vpc ec2 arp Branch: Affected Facter version: 1.6.10 (From the list) I ran into a buglet in facter 1.5.9rc6 (from tmz repo). In normal AWS instances it works great. In VPC instances if doesn't work. This seems to be because VPC instances don't use the fe:ff:ff:... MAC addresses. <pre> /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 02:67:4E:E1:26:30 inet addr:172.17.129.24 ... /sbin/arp Address HWtype HWaddress Flags Mask Iface 169.254.169.253 ether 02:67:4E:C0:00:01 C eth0 172.17.128.1 ether 02:67:4E:C0:00:01 C eth0 /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 02:67:4E:DA:58:16 inet addr:172.17.128.126 /sbin/arp Address HWtype HWaddress Flags Mask Iface 169.254.169.253 ether 02:67:4E:C0:00:01 C eth0 172.17.128.1 ether 02:67:4E:C0:00:01 C eth0 </pre> Of the two VPC EC2 instances I've seen, the MAC address always start with 02:67:4E. I have only seen two instances, both in the same VPC, so I don't know if this holds for every VPC instance, YMMV. in ec2.rb , the following seemed to work: <pre> def has_euca_mac? !!(Facter.value(:macaddress) =~ %r{^02:67:4[eE]:}) end </pre> -- You have received this notification because you have either subscribed to it, or are involved in it.
