Packet Sender overview

Packet Sender is an open source utility to allow sending and receiving TCP, UDP, and SSL (encrypted TCP) packets. The mainline branch officially supports Windows, Mac, and Desktop Linux (with Qt). Other places may recompile and redistribute Packet Sender. Packet Sender is free and licensed GPL v2 or later. It can be used for both commercial and personal use.

Features:
  • Controlling network-based devices in ways beyond their original apps
  • Test automation (using its command line tool and/or hotkeys)
  • Testing network APIs (using the built-in TCP, UDP, SSL clients)
  • Malware analysis (using the built-in UDP, TCP, SSL servers)
  • Troubleshooting secure connections (using SSL ).
  • Testing network connectivity/firewalls (by having 2 Packet Senders talk to each other)
  • Stress-testing a device (using intense network generator tool)
  • Tech support (by sending customers a portable Packet Sender with pre-defined settings and packets)
  • Sharing/Saving/Collaboration using the Packet Sender Cloud service.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What’s new in version 8.0.9

Updated on Jul 05 2022

  • Packet Sender now has HTTP(S) POST/GET as first-class citizens! When doing persistent connections, it will render the HTML response.
  • When performing POST requests, you may specify data, and Packet Sender is smart enough to set the MIME type when making the request.
  • For developers of home automation and control systems (there are many of you!), and to support the very reasonable request of "How do I send multiple packets at once?", Packet Sender now has a Panel Generator feature.
  • See the updated README on how to use it. You can now create a button and list packet names inside the button. Click the button, and they all get sent out. You can also transition to a new panel or add delays. This allows very rapid prototyping of a complex control system.
  • The intense traffic generator GUI gets a lot of use, but it is also pretty primitive. It will stay that way. The command line now has its own Intense Traffic Generator with more control knobs.
  • Double-click either ASCII or HEX to bring up a new multi-line editor. The ASCII version is rendered in raw format for easy copy/paste.
  • The portable version only requires "portableversion.txt" to become portable. This makes migrating to the newest version a lot easier.
  • I hope everybody can find information they need easier. Stay tuned for much-requested tutorials, especially with the new panel generator feature.
  • Packet Sender is now built using Qt 5.15 but it has support up to the newest Qt 6 for those that want to compile using it. The AppImage is still using Qt5.9 via ifdef separators.
  • My dog Bruce passed away last year. May his Easter Egg, Ctrl+DOG, that has been in there since Day 1 live on. I have added Ctrl+PUP for my new new puppy companions, Iris and Marigold.
