	DXF Import/Export Converter  License: Freeware
	Most CAD (computer aided design) systems and desktop publishing programs have the ability to read and write AutoDesk's DXF (Drawing Exchange Format) vector-based files. AutoCAD DXF is an open industry standard for the exchange of CAD drawings. DXF Converter allows to import DXF files to Pro Grapher format and vice versa export Pro Grapher documents to AutoCAD format. DXF Converter features: - Compatible with AutoDesk DXF Release 2000, 2002, 2004 / 2005; - All Pro Grapher's units are supported; - Easy and smart scaling; - Ability to invert Axe Y; - Ability to invert black and white colors; - Ability to convert contours only and contours with hatch and brush; - Royalty free licensing. Conversion process is fully automatic and needs no human intervention. Author: Stas Semenov| Date: 17-05-2005 | Size: 1431 KB

	PRTG - Paessler Router Traffic Grapher  License: Freeware
	PRTG Traffic Grapher is an easy to use Windows application for monitoring and classifying bandwidth usage. It provides system administrators with live readings and long-term usage trends for their network devices. PRTG is mainly used for bandwidth usage monitoring, but may also be used to monitor many other aspects of a network such as memory and CPU utilization. With PRTG Traffic Grapher the user receives comprehensive bandwidth and network usage data that helps to optimize the efficiency of the network. Understanding bandwidth and resource consumption is the key to better network management: Avoid bandwidth and server performance bottlenecks; Find out what applications or what servers use up your bandwidth; Deliver better quality of service to your users by being proactive; Reduce costs by buying bandwidth and hardware according to actual load. The Freeware Edition of PRTG Traffic Grapher is completely free for personal and commercial use and may be downloaded for free. PRTG Traffic Grapher is designed to run on a Windows machine in your network for 24 hours every day, and constantly records the network usage parameters. The recorded data is stored in an internal database for later reference. Using an easy to use Windows interface you can configure the monitored sensors as well as create usage reports. For remote access PRTG Traffic Grapher comes with a built-in web server to provide access to graphs and tables. All common methods for network usage data acquisition are supported: SNMP: Simple Network Management Protocol is the basic method of gathering bandwidth and network usage data. It can be used to monitor bandwidth usage of routers and switches port-by-port as well as device readings like memory, CPU load etc. Packet Sniffing: With its built-in Packet Sniffer PRTG can inspect all network data packets passing the network card to calculate the bandwidth usage. NetFlow: The NetFlow protocol is supported by most Cisco routers to measure bandwidth usage. Author: Paessler AG| Date: 11-07-2008 | Size: 26600 KB

	Paessler Netflow Tester  License: Freeware
	Paessler Netflow Tester dumps the data of all Netflow packets that a computer receives from a Cisco router. This can be useful when debugging bandwidth monitoring configurations based on Cisco's Netflow protocol. First the Netflow protocol must be enabled and configured on the router. Then the router must be given the IP address of the computer running Netflow tester so that the UDP data packets with Netflow data are sent to that computer. Just follow these simple instructions: 1) Download Paessler Netflow Tester and then start netflowtest.exe 2) Enter the IP and port number that you have configured as netflow packet target in your Cisco Router. Usually selecting "any IP" should work, in some cases the IP must be explicitly selected. 3) Enable "Start Netflow Collector". 4) You should now see a line in the logfile for each packet the computer receives. Each line shows the time, netflow version, number of flows and the IP of a packet (note: You need netflow version 5 for PRTG Traffic Grapher!) 5) Enable "Show Flow Data" to also show the corresponding flow data. 6) If you do not see any activity then the system does not receive any netflow data (e.g. due to misconfiguration of the router or a firewall blocking the packets, etc.) Author: Paessler AG| Date: 10-10-2005 | Size: 380 KB
