  • home | Policyd – Policyd v2 (codenamed "cluebringer") is a multi-platform policy server for popular MTAs. This policy daemon is designed mostly for large scale mail hosting environments. The main goal is to implement as many spam combating and email compliance features as possible while at the same time maintaining the portability, stability and performance required for mission critical email hosting of today. Most of the ideas and methods implemented in Policyd v2 stem from Policyd v1 as well as the authors' long time involvement in large scale mail hosting industry.
  • Using ALIAS-type DNS records for CNAME functionality on naked domains, and an easier alternative – If you've ever wanted to set up domains using cloud hosting services like Heroku or Windows Azure, you've probably come across a limitation with their platforms in regards to using naked domains (the version without the 'www' part, which is also called zone apex or root domain).
  • the MUST HAVE – Puoi produrre elettricità, idrogeno per cucinare e l'acqua calda di cui hai bisogno. Raccogli e purifica la pioggia, irriga il tuo orto e molto altro ancora…

  • 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.

  • Keepalived for Linux – Keepalived is a routing software written in C. The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage loadbalanced server pool according their health. On the other hand high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for router failover. In addition, Keepalived implements a set of hooks to the VRRP finite state machine providing low-level and high-speed protocol interactions. Keepalived frameworks can be used independently or all together to provide resilient infrastructures.
  • The BIRD Internet Routing Daemon Project – BIRD is an Internet Routing Daemon designed to avoid all of these shortcomings, to support all the routing technology used in the today's Internet or planned to be used in near future and to have a clean extensible architecture allowing new routing protocols to be incorporated easily. Among other features, BIRD supports: * both IPv4 and IPv6 protocols * multiple routing tables * the Border Gateway Protocol (BGPv4) * the Routing Information Protocol (RIPv2) * the Open Shortest Path First protocol (OSPFv2, OSPFv3) * the Router Advertisements for IPv6 hosts a virtual protocol for exchange of routes between different routing tables on a single host a command-line interface allowing on-line control and inspection of status of the daemon soft reconfiguration[...]
  • How to make MaxScale High Available with Corosync/Pacemaker | MariaDB – MaxScale, an open-source database-centric router for MySQL and MariaDB makes High Availability possible by hiding the complexity of backends and masking failures. MaxScale itself however is a single application running in a Linux box between the client application and the databases – so how do we make MaxScale High Available? This blog post shows how to quickly setup a Pacemaker/Corosync environment and configure MaxScale as a managed cluster resource.
