Just add to you config file (ex. ~/.ansible.cfg): [ssh_connection] pipelining=True Now run any playbook - you will see the difference 😄 Source (and extended info about): http://blog.ansibleworks.com/2014/01/15/ssh-connection-upgrades-coming-in-ansible-1-5/  external link

I was configuring GlusterFS on few servers using Ansible  external link and have a need to update /etc/hosts with hostnames for easier configuration. I found this one working: - name: Update /etc/hosts lineinfile: dest=/etc/hosts regexp='.*{{item}}$' line='{{hostvars.{{item}}.ansible_default_ipv4.address}} {{item}}' state=present with_items: '{{groups.somegroup}}' Source: http://xmeblog.blogspot.com/2013/06/ansible-dynamicaly-update-etchosts.html  external link
