  • Filtering Apache logs / conditional Logging – This can be very troublesome when trying to access certain web pages. The only way to get through is to make use of conditional logging (it is not the only way to control the contents of the logs) To do this, simply define an environment variable ,according to certain criteria, then request that the server does not write the file type within log when this variable exists

  • Ratuus – RATUUS is an easy to use, web based system for administration of POSTFIX virtual domains and users. Sounds good, but what does it really mean? Postfix mail server is able to work with non-system users, users which are not known to the operating system. This functionality is very useful since it gives you possibility to use one mail server for multiple domains without worrying that usernames will overlap. Like this you can have address [email protected] and also [email protected] and they can all point to different mailboxes. These kind of users are usually stored in some kind of a database, with MySQL database being most commonly used. And this is where RATUUS comes into play – it provides user friendly interface for managing these virtual users and domains. With RATUUS you can easily create, modify and delete domains, users and aliases and all your actions are immediately reflected to Postfix configuration. RATUUS is using the same database layout as famous PostfixAdmin so migration
  • Home · opensolutions/ViMbAdmin Wiki · GitHub – ViMbAdmin (pronounced vim-be-admin and meaning Virtual Mailbox Administration) is intended as an alternative to (and a near slot in replacement) for the popular but dated Postfix Admin application. It has been developed by Open Solutions, a company based in Dublin, Ireland specialising in PHP web application development, Linux and UNIX system administration and ISP grade networking and we are releasing it under a GPL V3 license. It is written in PHP using the Zend Framework, Doctrine ORM and Smarty with JQuery on the frontend.

  • Beleth – Security101 – Blackhat Techniques – Hacking Tutorials – Vulnerability Research – Security Tools – Beleth is a multi-threaded asynchronous SSH password auditing tool written in C. There are plenty of other password cracking programs out there that can do the job, but I wanted something small, fast, and custom as a proof of concept. After preliminary tests, Beleth was able to outperform both THC-Hydra and Ncrack. Beleth also allows you to run a remote command after successfully cracking a password.

  • Clustering with JBoss mod_cluster – jboss cluster – JBoss application server tutorials – Mod cluster is an http based load balancer which greatly simplify the setup of an http cluster. It ships as a set of modules which need to be installed on the httpd server and a Service Archive Library (.sar) which needs to be deployed on JBoss AS (It is built-in in JBoss AS 6/7).   Compared with the former mod_jk, the new mod_cluster has the great advantage to accept a dynamic configuration of httpd workers. This can be done through an advertise mechanism where all httpd workers communicate lifecycle events (like startup or shutdown) thus leveraging dynamic configuration of nodes.
  • How to configure mod_cluster with JBoss ? « JBoss – Like mod_jk, mod_cluster is also a httpd based load balancer which uses a communication channel to forward requests from the httpd to one of a set of application server nodes. So the question comes Why mod_cluster ? To answer this question we will let you know few advantages of mod_cluster over mod_jk and other httpd-based load balancers.

To use the SSL Checker, simply enter your server's hostname (must be public) in the box below and click the Check SSL button. If you need an SSL certificate, check out the SSL Wizard.
  • A Gentoo Linux Advanced Reference Architecture – The book "A Gentoo Linux Advanced Reference Architecture" is meant as a resource displaying the powerful features of many free software solutions that are supported on top of Gentoo Linux. It is a deep-dive approach in many aspects related to processes, supportability, maintainability based on Gentoo Linux system deployments. Unlike the existing, per-application documents that exist on the Internet (and which are a valuable resource to get into the gory details of many applications) and the per-distribution guides that provide information on using that particular distribution, this book will focus more on architecturing IT infrastructure for medium-sized enterprises. Smaller enterprises might find the reference architecture here too expensive or large – however, many services described in the book can be slimmed down into a smaller deployment as well.

  • WordPress › HyperDB « WordPress Plugins – HyperDB is a very advanced database class that replaces a few of the WordPress built-in database functions. The main differences are: * HyperDB can be connect to an arbitrary number of database servers, * HyperDB inspects each query to determine the appropriate database.
  • ClusterFoundry Blog Highly-Available and Load-Balanced WordPress Cluster – Part 1 – This article explains on how to setup a load-balanced WordPress cluster in a master-slave configuration. The load balancer(HAProxy) sits in front of 2 or more web server nodes (1 Master and 1 Slave) which has the same contents. HAProxy does not only distribute requests, but also checks the health of the services running on the node. If one of the nodes are down, all requests will be redirected to the remaining nodes.

  • Epoptes – Epoptes (ΕπÏŒπτης  – a Greek word for overseer) is an open source computer lab management and monitoring tool. It allows for screen broadcasting and monitoring, remote command execution, message sending, imposing restrictions like screen locking or sound muting the clients and much more! It can be installed in Ubuntu, Debian and openSUSE based labs that may contain any combination of the following: LTSP servers, thin and fat clients, non LTSP servers, standalone workstations, NX or XDMCP clients etc. Patches for other distros are welcome.
  • bcache – Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice if you could transparently get the advantages of both? With Bcache, you can have your cake and eat it too. Bcache patches for the Linux kernel allow one to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps even embedded.
