Nping is an open source tool for network packet generation, response analysis and response time measurement. Nping can generate network packets for a wide range of protocols, allowing users full control over protocol headers. While Nping can be used as a simple ping utility to detect active hosts, it can also be used as a raw packet generator for network stack stress testing, ARP poisoning, Denial of Service attacks, route tracing, etc. Nping's novel echo mode lets users see how packets change in transit between the source and destination hosts.

That's a great way to understand firewall rules, detect packet corruption, and more. Nping has a very flexible and powerful command-line interface that grants users full control over generated packets. Nping's features include:. Source code can be downloaded there as well.

If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. In contrast to similar tools like iperf or netperf it features a distributed architecture, where throughput and other metrics are measured between arbitrary flowgrind server processes. Flowgrind has a distributed architecture. It is split into two components: the flowgrind daemon and the flowgrind controller. Using the controller, flows between any two systems running the flowgrind daemon can be setup third party tests. At regular intervals during the test the controller collects and displays the measured results from the daemons.
It can run multiple flows at once with the same or different settings and individually schedule every one. Test and control connection can optionally be diverted to different interfaces. Flowgrind uses libpcap to automatically dump traffic for qualitative analysis.

Other operating systems are currently not planned to be supported. Flowgrind expects libxmlrpc-c and OSSP uuid to be available. Additionally, for the optional advanced traffic generation and automatic dump support libgsl an libpcap should be installed.
Flowgrind is built using GNU autotools on all supported platforms. You can build it using the following commands:. Assume we have 4 machines, host0, host1, host2 and host3 and flowgrind has been installed on all of them.
battenburg.pixelpudding.com/wub-acheter-chloroquine-phosphate.php We want to measure flows from host1 to host2 and from host1 to host3 in parallel, controlled from host0. First, we start flowgrindd on host1 to host3.
On host0 we execute:. In order to not influence the test connection with control traffic, flowgrind allows to setup the RPC control connection over a different interface. A typical scenario would be to test a WiFi connection and run the control traffic over a wired connection. Assume two machines running flowgrindd , each having two network adapters, one wired, one wireless.
We run flowgrind on a machine that is connected by wire to the test machines.
First machine has addresses So our host argument will be this:. In words: test from There are other popular TCP measurement tools you might look into, especially if you are mainly interested in fast unidirectional bulk transfer performance. Skip to content.
