Ansible Network Technology Preview

One of the greatest strengths of Ansible is the tremendous community of individuals that have risen to the challenge of building Ansible into the top automation platform available. It is that community that has driven Ansible to focus on innovative solutions that are guided by simplicity. The community that makes Ansible great has pushed to expand the capabilities of Ansible even further to encompass more platforms and technologies that comprise today’s most complex IT infrastructures.

In response to the many asks from the Ansible community and enterprise customers, we are pleased to introduce Ansible network technology preview, which is available immediately. The Ansible network technology preview is built on the success of Ansible 2.0, and provides newly developed integrations for working with network devices. Developed in partnership with network vendors and the Ansible community, support for networking devices gives the Ansible community the opportunity to extend full stack automation efforts to include network devices as well.

Capabilities

Ansible’s network support augments, rather than replaces, network operations team capabilities. The network modules focus on three key areas where automation can revolutionize how organizations work with their network gear:

Configuration Management
Test-Driven Networking
Continuous Compliance

Background

We built a set of Continue reading

Don’t let DROWN get you down

If you’re maintaining services on the internet, you know about the importance of keeping up to date with security patches as they come available. Today is no exception with the release of CVE-2016-0800, describing the ‘DROWN’ vulnerability in OpenSSL.

The key points of DROWN are that it can allow for passive decryption of encrypted traffic, via vulnerabilities in the obsolete SSLv2 protocol. Merely using SSLv2 for one service could cause the compromise the traffic of other services, even if they aren’t using SSLv2. More information can be found at http://www.drownattack.com/.

The Red Hat specific announcement can be found in the Red Hat Knowledgebase.

Obviously, this is a big deal, but patching your systems for DROWN doesn’t have to be a big deal, thanks to Ansible.

Here’s a sample playbook for Red Hat/Fedora/CentOS and Debian/Ubuntu systems (link to source):

- hosts: all
  gather_facts: true
  sudo: true
  tasks:
	- name: update openssl from apt if available
  	  apt: name=openssl state=latest update_cache=yes
  	  when: ansible_os_family == 'Debian'
  	  notify: restart_system
  
	- name: update openssl from yum if available
  	  yum: name=openssl state=latest update_cache=yes
  	  when: ansible_os_family == 'RedHat'
  	  notify: restart_system
