This is an alpha release testing various development changes and new Qt version (v5.14.1) for Windows.

This version of Packet Sender was tested with Windows 7 32-bit. It should work with later versions of 32-bit Windows. This version will not run on Windows XP. Auto-update is disabled in the config.

For performance reasons, the standard 64-bit version is recommended for operating systems that support it.

Major additions

• IP-specific port binding. For those that have multiple NIC or other complicated IP setups, this should be very helpful.

• UDP flooding tool For when the normal send system is not enough, you can now hammer a target IP with packets to see if your device can handle it. This feature is experimental, but it is stable enough to be useful.

Minor enhancements

• Send UDP even if port is disabled.
• Append \r in persistent connections remembers last state.

Bug fixes

• Packet Sender Cloud is now UTF-8 to handle more characters.
• Bug fix in named packets for command line parsing.

No new features. Just good ole fashioned performance improvements:

• Traffic log is significantly faster
• The IPv4/IPv6 toggle is back.

I've given up on the trying to make the Qt "Any" bind work reliably. I wish I did not need a toggle button, but testing has shown "Any" to be unstable. The app now uses AnyIPv4 or AnyIPv6.

Each OS gets a big improvement.

Windows

• Windows builds is now fully 64-bit. This was the last holdout.
• Qt Version bump
• OpenSSL version bump
• Codesign extended to late 2019

Linux

• AppImage now targets Ubuntu 16 (instead of Ubuntu 18) and should have better support .
• Qt Version bump

Mac

• Significant dark theme improvement
• Qt Version bump

• Packet Sender now supports UDP multicast (Experimental, IPv4 only)
• Non-loopback IP addresses are now displayed in the title bar
• Mac dmg is now notarized by Apple

This is an update with mostly bug fixes.

Noteworthy changes:

• Unlimited servers (comma separate the ports)
• Dark theme is now usable for Mac (making it look nice will have to wait)
• Periodic TCP connection hang fixed in command line version
• Qt version update

Also new:

• Now using CI / CD support for more frequent and stable releases

Packet Sender Cloud!

Packet Sender Cloud allows saving/retrieving/sharing your packets with the public. Like your favorite network utility, this service is free.

Other changes.

• Major performance for larger packets.
• Command-line sending size increase
• Auto-update service
• Packet Sender is now owned by NagleCode, LLC

• This release was abandoned due to a UDP bind problem in Windows.

Memory bottlenecks were reworked so Packet Sender can now support sending up to 100 MiB files. The previous limit was 10 MiB.

The code that was edited is used everywhere. Please open an issue if problems are found.
