![]() It has a lot going for it starting with its ease of use, cross-platform support, impressive documentation section (on the app's GitHub page), and ending with its immense set of advanced features. Packet Sender is one of the best apps of this sort out there. Last but not least, you can also automate your tests with the help of the app's command-line tools. You also get a quick single-button GET/POST request for control systems (testing HTTP), and the app can also be used for stress testing devices by "flooding" the network (generating intense traffic). by having 2 Packet Sender apps talk to each other). The app is also capable of testing network connectivity and firewall situations (i.e. The same feature can be used for malware analysis as well. Main usesĮven though it may not be obvious at first glance, Packet Sender has a lot of features that make it both stand out from the crowd and recommend it as a very competent network testing tool.įor example, you can test network APIs using the app's built-in UDP, TCP, and SSL clients. ![]() There are no guarantees whatsoever the receiver will receive all those packets, because of possible congestion/errors, or in the order they were sent, because of multiple factors, including multiple path routing, and varying degrees of congestion. With its help, you can effortlessly change between IPv4, IPv6, or even add your own custom IP. So into what touches the sender, as long it was able to dispatch the UDP packet, it was successful. Lastly, on the lower part of the window, there's the IP toggle section. This is triggered by the following command part of a code that listens on that specific port. When I receive the UDP packets, I get the message. The biggest section of the GUI is the middle one, and is the place from where you can choose and see the UDP, TCP, and SSL server status and ports. On my Linux machine, I am receiving UDP packets from another machine. On the upper right side of the GUI, you edit the fields of any saved packets. The section on the upper part of the main window displays the packet's name, destination address, port, and various data associated with it. Basic GUI presentationĭesigned with the Qt GUI framework, Packet Sender looks pretty much the same on all major platforms (of course, the app's theme will change slightly based on your system's theme). One very awesome aspect of Packet Sender is the fact that it can be used straight out of the box by most day-to-day users, while still providing enough "firepower" for advanced users. ![]() Packet Sender is a free, open-source, and cross-platform utility (works on Windows, macOS, and some Linux distributions) that provides all the necessary tools for sending and receiving TCP, UDP, SSL, as well as HTTP/HTTPS requests. Packet Sender is a very good place to start when testing and securing your networks. There's a lot that goes into testing a network's capabilities, hence the need for a specialized app for getting the job done as smoothly and as securely as possible.
