To answer these needs for security, compliance, and maintainability, we decided to launch this project as a common ground for requirements and their fulfillment.[…]

  • Come suddividere il log di WordPress in file separati tramite Apache – Otherplus Tech – Quando usiamo WordPress su un server Apache siamo quasi sempre abituati ad avere un solo file di log per gli accessi del nostro sito e alcune volte due file per dividere gli accessi normali da quelli in errore. Ultimamente ho avuto un’esperienza da un cliente proprio su questo argomento specifico e abbiamo dovuto generare i file in maniera tale da dividere le informazioni che riguardavano la sezione classica da quella admin, ajax, wp-content etc.
  • Using AWS Virtual Tape Library as Storage for Bacula – CAPSIDE – In this article, we will set up a Storage Gateway virtual machine on-premises that will cache and buffer backup data from Bacula.
  • Tiny Puppet – Yet Another Puppet Abstraction Layer – Tiny Puppet is a Puppet module that allows management of virtually any application on any Operating System: It’s based on the assumption that its user knows and wants to control how to shape the managed application’s configuration file: It’s not a joke, it just works like that, as long as our application can be installed via a native package (Tiny Puppet can manage also additional repos) and we know how to configure it.

  • Configuring OpenLDAP pass-through authentication to Active Directory – Alex Tcherniakhovski – Security – Site Home – MSDN Blogs – This particular functionality of OpenLDAP should be of special interest for environments where long term co-existence between OpenLDAP and Active Directory is required. By establishing pass-through authentication the following advantages could be achieved: Great end-user experience. No need to remember multiple passwords Increased security, due to the reduction of the attack surface (one less password store in the environment) Single password policy The rest of the post will expand on the instructions provided by the OpenLDAP 2.4 Administration guide on establishing pass-through authentication from OpenLDAP to Active Directory. Specifically, will will leverage the capability of SASL to use LDAP as an authentication back-end. In our case, Active Directory will play a role of such authentication back-end.

  • 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.

  • Scaling PHP apps via PHP-FPM clustering | Jamie Alquiza – PHP-FPM is a way to move your busted PHP handling from one place to another. It's essentially a pool of processes ready for PHP interpretation through FastCGI. While Apache will service client connections and static content, PHP requests are pushed into PHP-FPM. PHP-FPM allows the creation of process pools, each pool having it's own spawning model (e.g. static number of processes, dynamic with min/max, etc.) and other configurations (what UID/GID to run as, listening socket, etc.). A typical setup would be to create a PHP-FPM pool per tenant in a shared hosting environment.
  • KERMIT – KermIT is an opensource IT management solution. KermIT integrates best of breed opensource components with a Web user interface and dashboard to provide a central management solution for IT systems and applications. It provides a consistent, secure framework and a scalable architecture. It manages Linux, Unix and Windows systems. 'Small picture' KermIT relies in the backend on Puppet and MCollective. The license of the developments is the GPL v.3 for the generic part of the source code.
  • Random Start Times For Cron Jobs With Puppet : mycfg.net – Periodic scripts which use a common resource can end up being configured to run at the same time for multiple hosts. The result is that tasks like puppet runs or backups can take longer since they are trying to run all at once instead of being staggered. One way to do this is to give each cron task unique times manually. Another way is to add a random sleep before the task runs. My preferred way is to use the fqdn_rand function in puppet. Here's how it works.

  • CloudInit – Community Help Wiki – cloud-init is the Ubuntu package that handles early initialization of a cloud instance. It is installed in the Ubuntu Cloud Images and also in the official Ubuntu images available on EC2. Some of the things it configures are: setting a default locale setting hostname generate ssh private keys adding ssh keys to user's .ssh/authorized_keys so they can log in setting up ephemeral mount points cloud-init's behavior can be configured via user-data. User-data can be given by the user at instance launch time. This is done via the –user-data or –user-data-file argument to ec2-run-instances
  • Tsunami UDP Protocol – Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks. The project is based on original Indiana University 2002 Tsunami source code, but has been significantly improved and extended. As such, large portions of the program today are courtesy by Aalto University Metsähovi Radio Observatory. Includes FTP-like client and server command line applications for normal file transfers. It has additionally been extended for high rate real-time data streaming in eVLBI radio astronomy and geodesy (VSIB, PCEVN DAQ). Licensed under the original IU open source license.
