eBPF Port Knocking Tool
Knockles, is a port knocking tool based on eBPF. It allows you to remotely open a TCP connection while being completely invisible to port scanners.
A single SYN request is sent on an opened || closed port. It carries an OTP for authentication so you can be the only one to open a port. Once authentified, a random (HMAC based) port is opened for a TCP connection. Then, the port is closed as soon as a connection has been established.
