Our Cool Free Tools:

• Real-time NetFlow Analyzer - our newest FREE tool- a tool that captures and analyzes NetFlow data in real time to show you exactly what types of traffic are on your network, where that traffic is coming from, and where it is going.  Take the guesswork out of diagnosing network traffic spikes and troubleshooting bandwidth issues with this free network traffic monitoring tool.
• Exchange Monitor - a desktop dashboard that continuously monitors Microsoft® Exchange servers to deliver real-time insight into Exchange services, mail queue sizes, and host server health. Version 1.0.1, released on June 13, 2008, fixes an issue identified in a small subset of early deployments and includes a couple of enhancements.
• TFTP Server - a highly scalable, secure, and service-based TFTP Server that supports unlimited simultaneous transfers and extended option negotiation between client and server, including blocksize, transfer size, and timeout (as specified in RFCs 2347, 2348, 2349). Supports transfers sizes larger than 32MB.
• NetFlow Configurator – an easy-to-use tool for remotely and quickly configuring NetFlow v5 via SNMP on supported Cisco® devices. NetFlow Configurator also facilitates setting up collectors for Cisco NetFlow data, specifying the ports on which the collectors are listening, and enabling monitoring of inbound and outbound (ingress/egress) traffic data per interface.
• Advanced Subnet Calculator – an advanced IP address subnet calculator that supports forward and reverse DNS resolution, response time and address translation. It calculates subnets based on subnet mask, mask bits, host bits, number of subnets and hosts per subnet. It also supports classless inter-domain routing as well as printing and exporting to HTML or Excel.
• Wake-On-LAN – a tool that provides the ability to "power on" a PC remotely. This is accomplished by the generation of a "Magic Packet" to remotely power on PCs attached to networks. When the remote network adapter hears a "Magic Packet" created for its unique MAC address, the network adapter alerts the computer to power on. If Wake-On-LAN has been enabled in the computer’s BIOS settings, the system will power on as if the power button had been pressed.
• SNMP Assistant - a light-weight Windows System Tray utility that allows interaction with ipMonitor’s web-based MIB database repository called SNMP Center. The SNMP Assistant is designed to run in the background while you browse through SNMP Center, allowing you to scan and collect information from your SNMP-enabled network devices and applications. Once the data is gathered and returned, it is then displayed in HTML format within a new browser window.
