With the help of GFI.com’s Talk Tech To Me blog, we’ve compiled a list of 10 free software downloads designed to help router and IP administrators handle their tasks with as little cost as possible.
Net Tools 5
Net Tools is a set of host monitoring, network scanning, security and administration tools with an intuitive user interface. It is written in Microsoft Visual Basic 6, Visual C++, Visual C# and Visual Studio .NET, and among its features are IP address scanning, IP calculator, IP converter, port listening and scanning, traceroute and TCP/IP configuration.
Qcheck is a network troubleshooting utility from Ixia, the maker of network testing equipment. The software checks network response time, throughput, and streaming performance through a series of tests. It also runs “anywhere-to-anywhere” traceroute, Ixia claims. Qcheck runs on any computer running Windows 2000, NT or XP.
ManageEngine Free Ping Tool 2.0
The ManageEngine Ping Tool uses ICMP Ping to monitor the availability of servers, routers, switches and mail servers internally, and external websites. The tool collects parameters like round trip time and packet Time to Live, and presents them as graphs and reports on a dashboard. ManageEngine’s Free Ping Tool can monitor 10 servers and websites simultaneously.
Bitcricket IP Subnet Calculator
The Bitcricket IP Subnet Calculator from Wildpackets runs natively on both Windows and Mac OS X. It calculates subnets automatically, the company says, presenting bit-by-bit address visualisation and generating a table of subnets. The software also calculates CIDR routes, supports IPv6, discovers locally configured IPv4 and IPv6 addresses on both Windows and Mac, and enables cut-and-paste extraction on to a spreadsheet, word processor or e-mail.
Pinkie is a suite of network troubleshooting tools packaged in a single user interface. It is designed to reduce the number of applications and Windows administrators have opened at a time for tasks such as pinging hosts, forward and reverse DNS lookups, traceroutes, subnet calculations, port scanning, and file serving. It supports both IPv4 and IPv6 addresses.
Angry IP Scanner
Angry IP Scanner is a “very fast” open source IP address and port scanner, according to the angryip.org website. It can scan IP addresses in any range as well as any ports, and can be freely copied and used anywhere. It can also collect NetBIOS information and favorite IP address ranges, among other data, and supports Java plugins for extended functionality.
Ping Plotter (Freeware)
Ping Plotter Freeware runs on Microsoft Windows 98, ME, NT4, 2000, XP, 2003, Vista, 2008 and Windows 7. It features a multi-threaded trace engine and performs IP address to name lookups in a separate thread from traces. And if a route changes during a specific trace, Ping Plotter tracks the current route. The software’s graphical display shows route, hosts, packet loss percentage and latencies, and minimum and maximum response times for a range. Standard and Pro versions are also available for a charge.
IPplan is an IP address management and tracking application. IPplan performs DNS administration, configuration file management, customizable circuit management with templates, and template customizable hardware information storage. IPplan can support single or multiple networks, and customers with overlapping address space.
Blast v2.0 is a free TCP stress test tool from McAfee. It can help spot potential weaknesses in network servers. It allows users to monitor buffer sizes before sending data, and fixes the effect of HTTP timeouts when sending GET strings.
TCPView is a Windows program that displays listings of all TCP and UDP endpoints, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, and XP, TCPView also reports the name of the process that owns the endpoint. TCPView is a subset of the Netstat program that ships with Windows.
