Hi,
I don't know if I used a good subject because I am not
familiar with linux kernel programming. I heard it may
meet my need from someone.
                                                                                
I want to write a program which can filter (or just check)
internet packets before other applications. It is like
a guard which collects all internet traffic, even belonging
to other application, and then pass the packet to where it is
supposed to go (might be other high level application).
                                                                                
The main point is that these high level applications won't
notice the guard's existence. I heard programming in kernel
level can achieve this. After searching the internet, I found
some materials, but they are not specific enough for my requirement.
                                                                                
I have "Linux Device Drivers, 2nd Edition By Alessandro Rubini &
Jonathan Corbet". Still reading it. So far, didn't find things
about what I mentioned above.
                                                                                
Anyone knows good documents/toturial/material for me?
                                                                                
Thanks
