Getting a DNS TXT record in Ruby

I need to get the txt field from the DNS record.

Is there any ruby api to do something like this?

nslookup -q=txt xxxx.com

Answer

Try installing the dnsruby gem.

The code is actively maintained, and used in some significant production systems.

require 'rubygems'
require 'dnsruby'
include Dnsruby

# Use the system configured nameservers to run a query
res = Dnsruby::Resolver.new
ret = res.query("google.com", Types.TXT)
print ret.answer

(Code tested on MacOS X - prints the Google SPF record)
