Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It also supports TCP connections using SSL, intense traffic generation, HTTP(S) GET/POST requests, and panel generation. It is available for Windows, Mac, and Linux. It is licensed GNU General Public License v2 and is free software.[1] Packet Sender's web site says "It's designed to be very easy to use while still providing enough features for power users to do what they need.".[2]
Uses
Typical applications of Packet Sender include:
- Troubleshooting network devices that use network servers (send a packet and then analyze the response)
- Troubleshooting network devices that use network clients (devices that "phone home" via UDP, TCP, or SSL—Packet Sender can capture these requests)
- Testing and development of new network protocols (send a packet, see if device behaves appropriately)
- Reverse-engineering network protocols for security analysis (such as malware)
- Troubleshooting secure connections (using the SSL server and client).
- Automation (via Packet Sender's command line interface or resend feature)
- Stress-testing a device (using intense network generator tool)
- Sharing/Saving/Collaboration using the Packet Sender Cloud service
Packet Sender comes with a built-in TCP, UDP, and SSL server on multiple ports a user specifies. This remains running listening for packets while sending other packets.
