[Puppet Users] buglet in ec2 facts in facter 1.5.9rc6
Hello...
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.
/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
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:
def has_euca_mac?
!!(Facter.value(:macaddress) =~ %r{^02:67:4[eE]:})
end

To the optimist, the glass is half full.
To the pessimist, the glass is half empty.
To the engineer, the glass is twice as big as it needs to be.

I''ve put this in as: http://projects.puppetlabs.com/issues/7559 and this will cause us to cut another RC for Facter 1.5.9> > > /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 > > > > Of the two VPC EC2 instances I''ve seen, the MAC address always start > with 02:67:4E.

EC2 instances than waiting for a fix for this buglet. VPC EC2 instances are probably not in use by very many people and the VPC EC2 servers I found this bug on are not production. <snip> p.s. I really like the Portland,OR train system. $2.35 from downtown to the airport beats a $20-$50 cab in LA anyday. -- Christopher McCrory To the optimist, the glass is half full.
