[SunHELP] How can I hide the type of the operating system from scanners?

[Takacs Istvan]

Hi,

Is there a way to hide the type of the operating system?
When I run nmap than it can detect that it's a Solaris 8
operating system;

"Remote operating system guess: Sun Solaris 8 
early acces beta through actual release"

Do you have any good trick to hide this information
from netcraft and the scanner programs?
Or should I change something in the IP stack of
the OS if I had the source?

Thanks in advance!

Regards;
