I can't get the point in this problem ...
this code works fine ...
require 'resolv'
r = Resolv::DNS.new
puts r.getaddress("www.google.com")
r.each_resource("urubatan.com.br", Resolv::DNS::Resource::IN::A) { |mx|
puts mx
}
but if I change to this
require 'resolv'
r = Resolv::DNS.new
puts r.getaddress("www.google.com")
r.each_resource("urubatan.com.br", Resolv::DNS::Resource::CNAME) { |mx|
puts mx
}
ot this (that is what I want to do)
require 'resolv'
r = Resolv::DNS.new
puts r.getaddress("www.google.com")
r.each_resource("urubatan.com.br", Resolv::DNS::Resource::MX) { |mx|
puts mx
}
I get this error:
/usr/lib/ruby/1.8/resolv.rb:1171:in `pack': can't convert nil into

I think it is a bug in the ruby base library.
I'm using ruby 1.8, and I have tried this in tree different machines ...
Can some one help me with this please?
Thanks.
