Hi, [1] is the module I wrote for intercepting the system call fork(). I have taken the conventional way of hooking the system call. Firstly I found out the address of the sys_call_table from the System.map. Then I used it in the module to substitute for the original fork() with my own version of fork.My version does nothing more than printing a message and returning the original fork(). It didn't gave any errors when loaded to kernel using the insmod. However it seems that the module had no affect on the sys_call_table[] since the fork() is working perfectly after the insertion of module and it does not show me the message it was supposed to print. Can someone figure out the problem? I am using 3.2.0-4-686 version of kernel. [1] http://pastebin.com/aWN3jdQU -- *Regards,* *Paul Davies C* vivafoss.blogspot.com
