  • 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.
  • Wazuh | Augmenting OSSEC Host IDS – Wazuh contributes to Open Source Security developing and integrating new modules to extend OSSEC capabilities and functionality.

  • One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
  • Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via ]
  • Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

  • open.NASA – a collaborative approach to open, direct, and transparent communication about your space agency – is a collaborative platform for the open government community to share success stories and projects they are working on. The content on this site is written by NASA employees and contractors across the agency. We are excited to highlight the ways that transparency, participation, and collaboration are being embraced by NASA policy, technology, and culture – and the amazing future that becomes possible because of that commitment.
  • VirtuaLinux – Official WebSite – VirtuaLinux is a Linux meta-distribution that allows the creation, deployment and administration of virtualized clusters with no single point of failure. VirtuaLinux architecture supports disk-less configurations and provides an efficient, iSCSI based abstraction of the SAN. Clusters running VirtuaLinux exhibit no master node to boost resilience and flexibity.
  • tindie | For Sale – buy & sell homemade gadgets, kits, & parts. Raspberry Pi, Arduino, 3dprinting, and more! As seen on: hackaday, reddit, wired, treehugger, and hackaday (again)

    It's also a second generation wiki offering the ability to install and develop small applications inside wiki pages.
    Export wiki pages to PDF, ODT, RTF, XML or HTML. Easily turn Office documents (MS Office, Open Office, PDF, etc) into wiki pages.
    Use XWiki's RESTful and XML/RPC remote APIs to easily integrate XWiki with your application.
    Documents are stored in a relational database. Use your favorite database.
    Create applications by grouping several pages together. Import and export Applications to/from your wiki.
    various authentication mechanisms suported by XWiki (Form, Basic, LDAP, Custom, etc).
    Install/update/remove extensions in/from the wiki
    Allows creating XWiki macros through wiki pages
  • – Finding the open source solutions ready for the enterprise
  • Ring of Saturn Internetworking – These documents and tools were created by me while I worked at Verio as well as all the time since then. As such, there are still some references to "customers" and maybe even some procedures we used while I worked there. Since the content is just fine, just a bit weird to read, I haven't updated these and am focusing more on adding new content rather than fixing these "bugs".
