Winsock Tester 1.0

Winsock Tester is a lightweight Windows utility for validating and troubleshooting socket connections. Built on the Windows Sockets (Winsock) API, it helps developers, testers, and network administrators open TCP or UDP sessions, act as a client or simple listener, send and receive data, and inspect responses in real time. It’s ideal for verifying open ports, reproducing connection scenarios, and diagnosing timeouts or malformed data.

Key features:

• TCP and UDP testing over the native Winsock stack
• Client and basic server/listener modes
• Connect, bind, and listen on custom IPs and ports
• Send/receive data in text or hex with selectable line endings
• Adjustable timeouts, buffer sizes, and retry behavior
• Real-time logging with timestamps for easier diagnostics
• IPv4 support (IPv6 when available in your environment)

Typical uses:

• Verifying service availability and port forwarding
• Debugging handshake, timeout, and message-framing issues
• Simulating simple client requests during development
• Capturing reproducible steps for bug reports and support tickets
