What it does
Packet Sender exchanges TCP, UDP, SSL and DTLS data, sends HTTP requests and supports scripted network testing.
Define the ASCII or hexadecimal payload and choose the target protocol and port for a controlled listener test. Packet Sender can act as client or server for TCP, UDP, SSL and DTLS; two instances can help investigate connectivity between endpoints. Its HTTP client supports GET/POST requests with authentication headers, and command-line or predefined-packet workflows help repeat a support check. Keep the payload and protocol with the result, since success only describes that exchange. The desktop utility is free and open source for Windows, macOS and Linux. Cloud save/share and panel generation add separate workflows; use them deliberately when packet definitions contain sensitive data.
