Hi All,

Just came across this little tool for the Linux 2.4 Kernel, and it sound pretty good in theory.

Basically, this patch will fool nmaps OS fingerprinting feature.

The characteristics that can be changed are:

- TCP Initial Sequence Number (ISN)
- TCP initial window size
- TCP options (their types, values and order in the packet)
- IP ID numbers
- answers to some pathological TCP packets
- answers to some UDP packets
How can a hacker compromise what he thinks is a Win2K machine and launches his attack based on Win2K vulnerabilities, when in reality, it is a Linux machine?

I know that this wouldnt replace any other security tools like Firewalls and Antivirus, and it could be considered to some extent "Security by Obscurity", but I think that it could be a nice inclusion to your systems overall"Security Suite".
