- Coderwall | Dump all variables – For debugging purposes it can be useful to not just dump hostvars but also all other variables and group information. You can do this using a jinja template which you could include in a debug task
- Using Ansible to create AWS instances | Tivix – Ansible is a great tool for enhancing productivity. With a vast array of modules to choose from, it can save you a lot of time by automating away common tasks. At Tivix we use it for single-command deployment, with the most common destination being Amazon EC2 instances created beforehand. Since Ansible is capable of managing EC2 resources, we can improve this setup by making a playbook to create an instance for us.
- Home | OpenSCAP portal – The OpenSCAP ecosystem provides multiple tools to assist administrators and auditors with assessment, measurement and enforcement of security baselines. We maintain great flexibility and interoperability, reducing costs of performing security audits.
The OpenSCAP project provides a wide variety of hardening guides and configuration baselines developed by the open source community, ensuring that you can choose a security policy which best suits the needs of your organization, regardless of its size.
SCAP is U.S. standard maintained by National Institute of Standards and Technology (NIST). The OpenSCAP project is a collection of open source tools for implementing and enforcing this standard, and has been awarded the SCAP 1.2 certification by NIST in 2014.

- Hardening Framework – […] Server hardening is a well-known topic with many guides out in the wild. Why this project? At Deutsche Telekom we need to manage thousands of servers for customers and ourselves. All servers need to be configured properly and maintained, which is difficult and time-consuming to get right. To answer these needs for security, compliance, and maintainability, we decided to launch this project as a common ground for requirements and their fulfillment.[…]

- LDAP org chart | bitcube.co.uk – For centralised authentication and authorisation, LDAP is the de-facto standard. Whether in its pure form on Unix or in Active Directory guise on Windows, everyone uses it. What many people don't realise is that you can store all sorts of useful (and not so useful) information in LDAP. One field which can be useful is the "manager" attribute. One of our customers use that and so we've written a small script to graph it using the excellent Graphviz tool. It will probably need customising for specific cases, however we hope that people find it useful nonetheless. If you want to alter the output, do have a look at the record format documentation.
- Puppet errors explained | bitcube.co.uk – Puppet is a wonderful system automation tool, however the learning curve can be a little steep. We've collected some of the errors messages and "strange" behaviour you may come across together with explanations to help overcome these hurdles and boost adoption of this fabulous tool. If you have any useful errors and explanations, please do send them in and we'll update this article.
- SCAP: Guide To The Secure Configuration of Red Hat Enterprise Linux 5 – This guide has been created to assist IT professionals, in effectively securing systems with Red Hat Enterprise Linux 5.
- DNS Load Balancing and Using Multiple Load Balancers in the Cloud – […] Load balancing in general is a complicated process, but there's some secret sauce in managing DNS along with multiple load balancers in the cloud. It requires that you draw from a few different sets of networking and “cloudy” concepts. In this second article in my best practices series (my first post covered how to use credentials within RightScale for storing sensitive or frequently used values), I'll explain how to set up load balancers to build a fault-tolerant, highly available web application in the cloud. Here's what you’ll need: Multiple A records for a host name in the DNS service of your choice Multiple load balancers to protect against failure […]
- gdnsd – gdnsd is an Authoritative-only DNS server which does geographic (or other sorts of) balancing, redirection, weighting, and service-state-conscious failover at the DNS layer. gdnsd is written in C using libev and pthreads with a focus on high performance, low latency service. It does not offer any form of caching or recursive service, and notably does not support DNSSEC. There's a strong focus on making the code efficient, lean, and resilient. The code has a decent regression testsuite with full branch coverage on the core packet parsing and generation code, and some scripted QA tools for e.g. valgrind validation, clang-analyzer, etc. The geographically-aware features also support the emerging EDNS Client Subnet draft for receiving more-precise network location information from intermediate shared caches.

- Hardening the Linux server – Summary: Servers — whether used for testing or production — are primary targets for attackers. By taking the proper steps, you can turn a vulnerable box into a hardened server and help thwart outside attackers. Learn how to tighten Secure Shell (SSH) sessions, configure firewall rules, and set up intrusion detection to alert you to possible attacks on your GNU/Linux® server.
