PACKET SENDER FOR WINDOWS GENERATOR
Ostinato A network traffic generator that is open source, but charged for. It's Open Source, easy to use, and comes off as a professional application. Packet Sender A free, open-source packet generator that runs on Windows, Linux, and Mac OS. Packet Sender is what we live for here at MajorGeeks. Packet Sender has numerous uses, including testing automation, testing network APIs, malware analysis, testing network connectivity, firewalls, tech support, and security research.

You will want to download the portable version to use the command line. You can also use Packet Sender from the command line allowing you to automate or use scripts. Finally, the About tab has links to the documentation, about, and donate. The Tools tab has a subnet calculator as well. Under the File tab, you will find your settings, plus the ability to import or export packets. An information window is available below that, and the third window with a log of activity. Available fields include Packet Name, ASCII Representation, HEX Representation, Address (IPv4, v6, DNS lookup), Port, Resend Delay, and quite a bit more. The interface is relatively easy to use, especially for networking geeks, but it seems simple enough to use at any skill level. There are three primary windows to focus on when you get started.

Packet Sender can send and receive UDP, TCP, and SSL on the ports of your choice between a server and client computers.ĭocumentation is available after installation, and you will need to allow your firewall access.
