Yes and no. Try running "facter | grep ipaddress" on the client. This will give you the names of variables you should be using instead that are listed by interface. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I'll have to put some effort on my nagios module to provide for an override for the ip address, then. -- Gabriel Filion -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hi,
I was wondering *when* would this part of the ipaddress.rb fact code
would be used:
--(0)> tail -20 /usr/lib/ruby/site_ruby/1.8/facter/ipaddress.rb
Facter.add(:ipaddress, :timeout => 2) do
setcode do
if hostname = Facter.value(:hostname)
# we need Hostname to exist for this to work
host = nil
if host = Facter::Util::Resolution.exec("host #{hostname}")
list = host.chomp.split(/\s/)
if defined? list[-1] and
list[-1] =~ /[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/
list[-1]
end
else
nil
end
else
nil
end
end
end
--(naresh.ve@puppet)-(~)--
--(0)> irb -rfacter
irb(main):001:0> Facter::Util::Resolution.exec("host puppet.domain.com")
=> "puppet.directi.com has address a.b.c.d"
irb(main):002:0> host = Facter::Util::Resolution.exec("host puppet.domain.com")
=> "puppet.directi.com has address a.b.c.d"
irb(main):003:0> list = host.chomp.split(/\s/)
=> ["puppet.directi.com", "has", "address", "a.b.c.d"]
irb(main):004:0> if defined? list[-1] and list [-1] =~
/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/
irb(main):005:1> list[-1]
irb(main):006:1> end
=> "a.b.c.d"
irb(main):007:0>
(masked my IP with a.b.c.d)
If this part were the default/first piece of code that'd be used to
produce the ipaddress fact, setting the right A record for the fqdn
should solve the problem?

hmm this fact looks like it won't work for any host that doesn't
resolve, which would be problematic for something like a test setup with
virtual machines.
