Nmap: —rate too high, packets dropped – слишком высокая скорость сканирования, пакеты теряются.

When using Nmap for network scanning, it is important to set the scanning rate appropriately to avoid packets being dropped. However, sometimes users may encounter the error message «—rate too high, packets dropped» which indicates that the scanning speed is causing packets to be lost.

There are several reasons why this error may occur. One common scenario is when the network being scanned is unable to handle the high rate of packets sent by Nmap. This can lead to packet loss and inaccurate scan results.

How to Resolve the Issue:

• Reduce the scanning rate: One way to fix this issue is to lower the scanning rate in Nmap. This can be done by adjusting the «—rate» parameter to a lower value, allowing the network to handle the scanning traffic more effectively.
• Use connection throttling: Another solution is to use connection throttling tools like Nsock to control the rate at which Nmap sends packets. This can help prevent packets from being dropped due to high-speed scanning.
• Optimize network settings: It is also important to ensure that the network being scanned is optimized for high-speed scanning. This may involve optimizing network configurations, increasing bandwidth, or improving network stability to prevent packet loss.

Conclusion:

By addressing the «—rate too high, packets dropped» error in Nmap, users can ensure more accurate and reliable scan results without experiencing packet loss. Taking the necessary steps to optimize scanning speed and network settings can help improve the overall scanning experience and enhance network security.
