Freeware In Network Tools

With this free software you can create local wireless communities where bulletin board, chat, and forums available locally with or without Internet service; Share your broadband service, split your ISP bill, control shared bandwidth; and Run your own free or commercial wireless hotspot network.

NetBrute allows you to scan a single computer or multiple IP addresses for available Windows File & Print Sharing resources. This is probably one of the most dangerous and easily exploitable security holes. It is common for your novice users to have their printers or their entire hard drive shared without being aware of it. This utility will help you to find these resources, so you can secure them with a firewall or by informing your users how to properly configure their shares with tighter security.

PortScan allows you to scan a single computer or multiple IP addresses for available Internet services. This will allow you to identify which TCP ports need to be blocked by your firewall, if you wish to secure them. Or it will allow you to identify unused services that are running, so they can be stopped.

WebBrute will allow you to scan your web directories that are protected with HTTP authentication, testing the security strength of your users passwords. This will allow you to better enforce your password maintenance policies to ensure that your users are not using easily guessed passwords, or passwords that match their username.

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.

Anonymity is not a boolean - we are not trying to make something "perfectly anonymous", but instead are working at making attacks more and more expensive to mount. I2P alone is what could be called a "low latency mix network", and there are limits to the anonymity offered by such a system, but the applications on top of I2P, such as Syndie, I2P mail, and I2PSnark extend it to offer both additional functionality and protection.
