Gravacacher is very simple and lightweight caching server designed for one specific purpose: to cache avatar images from services like www.gravatar.com, which provide "globally recognized avatars". Typically, Gravacacher will be deployed on sites that host blogs or forums which depend on gravatars. Gravacacher supports a security mechanism that allows it to answer only queries made via URLs generated by your server software, such as blog or forum engines, permanent cached entities, and both positive and negative TTLs when caching.
IP Traffic Volume uses Linux kernel iptables to log incoming and outgoing bytes though your network device(s) and can dump summarized log statistics in ASCII to the console or display in HTML via the included CGI interface for displaying on a Web server. It is highly configurable as to what kind of traffic is counted, e.g. to and from specific ports and/or specific IP addresses or groups of ports and addresses. It uses a mininum of resources and doesn't need a database for the logged data.
The Machine Inventory Database (MID) is a Perl-based CGI interface to manage the machines on and off your network, both from the IP assignment perspective and the asset-tracking perspective. On top of acting as a frontend to a handful of MySQL tables, it handles IP assignment and acts as a frontend to the configuration files for BIND, YP, and DHCPD to reduce the chance for typos in the configuration files which tend to bring down service.
The Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.). It employs tag cleaning and paging so that Web pages it can access have far greater chances of being rendered on devices that cannot display overly large or complex pages. It is simple, but it seems to substantially extend the portion of the Web available from devices that otherwise display messages like "413: Page cannot be displayed."
Multi-router looking glass for PHP is a full rewrite of the Perl version of MRLG into PHP. It allows network administrators to execute commands on multiple routers via a nice Web interface. It is flexible, clear, and configurable. Default, per-router, and per-service options may be set. The Web-page layout and queries set are adjustable.
NetUP UTM is a universal billing system for internet service providers of any size. Its modern approach to traffic accounting makes the system compatible with all popular platforms and network devices. Its key features include realtime traffic processing, Cisco Netflow and IP Accounting data collection, support for RADIUS authentication, and cross-platform compatibility. The core of the system is a smart and reliable accounting engine working directly with network equipment. It supports up to 100,000 users at a total speed of up to 3 Gbps. A flexible ratings engine and efficient administration tools make UTM a complete solution for IP/VoIP/WiFi/dial-up billing.
Network and Service Monitoring System is a tool for assisting network administrators in managing and monitoring the activities of their network. It helps in getting the status information of critical processes running at any machine in the network. It can be used to monitor the bandwidth usage of individual machines in the network. It also performs checks for IP-based network services like POP3, SMTP, NNTP, FTP, etc., and can give you the status of the DNS server. The system uses MySQL for storing the information, and the output is displayed via a Web interface.
