Hello,
if you want a simple trick to do OS fingerprinting, I
suggest you to use the initial window size of a TCP session
establishement.
If you use that, you can create a table for each OS I've
seen by parsing the file at:

Or better, use the database in SQLite format:
DB Schema:

DB:
http://www.gomor.org/files/sinfp.db
Or even better, use SinFP:
