TCP Timestamp Response

The GigaVUE‑OS does not respond to Transmission Control Protocol (TCP) timestamp requests.

The response to such a request is a TCP timestamp response. The response can be used to approximate the uptime of the GigaVUE node, which can then be used in is DoS attacks.

In addition, some operating systems can be fingerprinted based on the behavior of their TCP timestamps, therefore this is disabled.
