This is Task 19 of the Eudyptula Challenge
|
|
------------------------------------------
|
|
|
|
Handling delayed work is easy now, right? So, time to move on to
|
|
something totally different. How about networking? We have been
|
|
ignoring that part of the kernel, so let us now focus on the network
|
|
side of the kernel, as that is a huge reason for why Linux has taken
|
|
over the world.
|
|
|
|
For this task, write a netfilter kernel module that does the following:
|
|
- monitors all IPv4 network traffic that is coming into the machine
|
|
- prints the id to the kernel debug log if the network traffic stream
|
|
contains your id.
|
|
- properly unregisters you from the netfilter core when the module
|
|
unloads.
|
|
|
|
Test this by sending yourself an email with your id in the subject, much
|
|
like the email you need to send back to me.
|
|
|
|
Send in the proof and the .c file for the module.
