Hi Hackers,
I'm wondering about two things, how does the kernel detect that a
user logs on a tty, and what should I know if I was to write a kernel
module that detects it (And does something about it)? Must I
read the TCP in-packets for port 23 and detect if a user logged on?
I'm pretty unsure about this..
I know it could easier be implemented in userland by reading the
_PATH_UTMP file, but I'm more interested in doing it in kernel space.
Thanks in advance
