this does not work either.
Code:
#!/usr/bin/env ruby

require 'resolv'

puts Resolv.getname("10.0.2.1").to_s


result:

/usr/lib/ruby/1.8/resolv.rb:128:in `getname': no name for 10.0.2.1
/(Resolv::ResolvError)
        from /usr/lib/ruby/1.8/resolv.rb:64:in `getname'
        from ./test.rb:6

so as I said before, I don't have reverse dns (e.g. to get in-addr.arpa
from dns) and host command works, rubys' commands dont. :-( I guess I will
have to use `host` insted of pure ruby code.
