Resolve DNS MX host entry

How do i do it in Ruby?
Now i am using “host” command but that is not optimal.

def getMX(host)
srand()
e_mx = host -t mx #{host} # Should be done internally, but HOW?
mxhosts = []
i = 0
e_mx.each do |line|
s = line.split(/by /)
mxhosts[i] = s[1]
i+=1
end
return mxhosts[rand(mxhosts.length)].chop
end

You can use the ‘resolv.rb’ library that comes with Ruby:

res = Resolv::DNS.new.getresources(host, Resolv::DNS::Resource::IN::MX)

Ahhh, thanx! I am just in the first day of learning Ruby.
