Overwriting values is not going to stop many of the different detection methods. As mentioned - just one thingie.

Me? I just change banners.

Hello All:

Is there a PRACTICAL solution from PRODUCTION
environments that can be used to block OS detection
from tools like NMAP? I googled and read some notes
but couldn't find a real world solution to blocking
Windows & Linux OS detection.

I'm quite sure I'll get the right inputs here.

Thank you.
