  • S3QL – nikratio – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
  • Using Foreman, an Opensource Frontend for Puppet – – The recent vulnerability in bash, got me running to update bash. It’s easy when you have maybe one or two Linux servers, but what do you do if you have 100’s or even thousands or servers? You need to use a server configuration and management tool like puppet. However, instead of using the command line, I wanted a GUI tool where I could select the servers or server group and select an action. That is where I found Foreman, A opensource tool which not only handles configuration of your servers but also does provisioning. Foreman is easy to install, opensource, has community based support and a good deal of documentation.
  • Power Up Your Authentication with Open LDAP and Puppet | DataCentred – When you’re busy automating your infrastructure, a recurring theme that causes questions and problems is this: how do you reliably integrate your data (which changes all the time) into your configuration? As a hosting company, we find ourselves needing to tend to an ever-increasing number of devices: servers, switches, routers, hypervisors, you name it. A staple mechanism for centralised authentication is the use of an LDAP server to manage a directory of users and groups and to perform authentication of credentials and privileges on behalf of other devices on the network.
  • Enterprise/Authentication/KerberosServices – Ubuntu Wiki – This article explains a little bit about the Kerberos protocol and how it can be used in Ubuntu. It's not a thorough manual, use more authoritative sources to get more accurate information and update if you see obvious mistakes.
