Tiny TCP Relay

Minimal concurrent TCP server in Go using goroutines and channels. It listens on :3000, accepts connections, spins a goroutine per client, and echoes whatever bytes it reads back to the sender.

Incoming messages are also pushed into a buffered channel and printed with a timestamp and remote address in a separate goroutine.

Technical Details

• Goroutine per client
• Buffered message channel (size 10)
• Raw TCP socket communication
• Echo back of received bytes
• Message logging with timestamp and remote address
