- Phamm – PHP LDAP Virtual Hosting Manager – Postfix MTA Fronted – Phamm is a front-end written in PHP to manage virtual services using a OpenLDAP directory back-end. A couple of scripts and tools included help you to set up services.
- WP-Cli Tutorial – How to Use WP-Cli with Your WordPress Site – WP-Cli is a command line interface which allows the users to manage their WordPress web sites from the command prompt. Upgrades can be performed, backups can be generated, new posts can be published and most of the regular admin actions can be performed with a set of commands. In this tutorial we will explain how to use the WP command line interface in order to complete regular administrative tasks like upgrades, database backup creation, plugins and themes installations and removals, publishing and deleting posts, changing site's URL settings and getting help on chosen commands. Note that WP-Cli requires an SSH access.
- WordShell – WordPress from the command-line | WordPress from the CLIWordShell – WordPress from the command-line – WordPress from the command-line (Linux, Mac, Windows, BSD, Solaris, etc.) Don't log in to the dashboard on 20 sites one after the other; just type one command. Automate everything and use many bonus tools (e.g. automated backups, maintaining custom patches and version control). This is the time-and-money saver that WP admins have been waiting for.

- 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.

- 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.
