Updating DNS settings on multiple devices

Imagine I have a list of RouterOS devices that all need primary and secondary DNS settings updated. Here's an

example Ruby script to do this:

#!/usr/bin/env ruby

require 'rubygems'

require 'mtik'

## List of devices (hostnames/IPs) to contact:

devlist = [

'10.0.0.4',

'10.0.0.5',

'10.0.0.22',

'10.1.44.22',

'10.1.44.79'

]

## Example assumes all devices use the same API user/pass:

USERNAME = 'admin'

PASSWORD = 'password'

## Set DNS to these IPs (if these were the name servers in question):

PRIMARYDNS = '10.20.30.2'

SECONDARYDNS = '192.168.44.2'

## Set to 1 to do each device serially, or greater to fork parallel processes

MAXFORK = 1

children = 0

devlist.each do |host|

Kernel.fork do

puts "#{host}: Connecting..."

mt = nil

begin

mt = MTik::Connection.new(

:host=>host,

:user=>USERNAME,

:pass=>PASSWORD

)

rescue Errno::ETIMEDOUT, Errno::ENETUNREACH, Errno::EHOSTUNREACH => e

puts "#{host}: Error connecting: #{e}"

exit

end

## The MTik::Connection#get_reply() method executes a command, then waits
