Simplified Interface

: Easy management of TCP/UDP connections. Netcat GUI v1

# Send/Receive self.text_area = scrolledtext.ScrolledText(root) self.text_area.pack(fill="both", expand=True) self.send_entry = tk.Entry(root) self.send_entry.pack() tk.Button(root, text="Send", command=self.send).pack() Memory leaks during long listening sessions

• Memory leaks during long listening sessions.
• GUI freezes when receiving large files (>500MB).
• No Unicode support – Broken characters in international logs.
• Antivirus false positives – Older versions were often quarantined.

Switching between TCP and UDP protocols in traditional Netcat requires using the -u flag and understanding the connectionless nature of UDP. The new GUI places a prominent, foolproof toggle switch at the top of the dashboard, ensuring you never accidentally try to force a TCP handshake over a UDP port.
