You might want to have a look at ansible (www.ansibleworks.com) for orchestration/configuration tasks like this. Very simple to set up and requires nothing but ssh and python on the target host. Takes care of all the ssh and sudo user transitions for you. For your case it would be as simple as. yum install ansible echo target_host > hosts ansible target_host -i hosts -s -m lineinfile -a 'dest=/etc/sudoers regexp="^username ALL=(ALL) NOPASSWD:"' replacing target_host and username as appropriate. You can even package that invocation in a playbook so you don't have to remember all the details next time. Hope this helps.
