Drupal is a modular content management system, forum, blogging and community engine. It is database driven and can be used with MySQL, MariaDB, PostgreSQL, and SQLite. Its features include (but are not limited to) discussion forums, Web-based administration, theme support, a submission queue, content rating, content versioning, taxonomy support, user management with a fine-grained permission system based on user roles (groups), error logging, support for content syndication, locale support, and much more. It is considered to be an excellent platform for developers due to its clean code and extensibility, and it can also be used as a Web application framework.
The j661 project provides a generic CDS (or ARINC 661 Server) in order to facilitate the understanding of the ARINC 661 standard, prototype ARINC 661 concepts and architectures, and facilitate the reuse of ARINC 661 specifications and artefacts between projects. The CDS architecture is designed to allow defining the Server behavior to be easily modified or extended. This is achieved by a modular plug-in architecture, allowing customization at runtime without changing anything in the Server core itself.
Lynx is a fully-featured WWW client for users running cursor-addressable, character-cell display devices (e.g., vt100 terminals, terminal emulators running on PCs or Macs, or any other character-cell display). It will display HTML documents containing links to files on the local system, as well as files on remote systems running HTTP, HTTPS, gopher, FTP, WAIS, NNTP, finger, or cso/ph/qi servers, and services accessible via logins to telnet, tn3270, or rlogin accounts.
Tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress HTTP, WebDAV, PostgreSQL, MySQL, LDAP, AMQP, and XMPP/Jabber servers. It simulates user behavior using an XML description file, reports many measurements in real time (statistics can be customized with transactions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET, POST, PUT, and DELETE methods, cookies, and basic/digest authentication. It also has support for SSL, WebSocket, and BOSH.
GLPI (Gestion Libre de Parc Informatique) is an information resource manager with an administration interface. You can use it to build a database with an inventory for your company (computers, software, printers, etc.). It has functions to make the daily life of the administrators easier, including a job/request tracking system with mail notification and methods to build a database with basic information about your network topology. It provides a precise inventory of all the technical resources (all their characteristics are stored in a database) and management and history of the maintenance actions and the bound procedures. It is dynamic and is directly connected to the users, who can post requests to the technicians.
NetXMS is a network monitoring and management system with a modular architecture. It can be used for monitoring an entire IT infrastructure, starting with SNMP-capable hardware (like switches and routers) and ending with applications on servers. The system has a three-tier architecture; the information is collected by monitoring agents (either its own agents or SNMP agents) and delivered to the monitoring server for processing and storing, where it can be accessed by using the management console. It features centralized configuration and centralized agent upgrades.
