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.
JoomlaWatch allows you to watch your Web site visitors and bots in real-time from the administration menu, particularly their IP addresses, countries they come from, geographical location on a map, which pages they are viewing, and their browser and operating system. It creates daily and all-time stats from this information plus unique, pageload, and total hits statistics. Furthermore, you can block harmful IP addresses, see blocked attempts stats, evaluate the trend charts, and create goals based on many parameters. In the frontend, it can show the top countries, user, and visit information for certain periods of time.
JavaCrontab is a local area network scanning tool. It scans for operating systems, MAC address, IP address, open ports, et cetera for all devices in your LAN and saves the data in a local MySQL database. It is meant to be automatically started by the crontab software every evening.
Nmap Observer is a small application that shows the results of an nmap scan in a Web interface. You just need to specify the range of the network on which the scan is to be performed. Then the scan results are saved to an XML file. Nmap Observer parses the results, saves the results to a database, and shows them to you.
