C++ keylogger

Po Googlu sem malo brskal o keyloggerjih za linux, pa sem naletel na tole:

Keylogging is very simple. It's all there in the kernel. You need to use module evbug (or evdev). If you modprobe evbug and do a dmesg you'll see something like this
Code:

[4298922.635000] evbug.c: Event. Dev: isa0060/serio0/input0, Type: 1, Code: 103, Value: 0
[4298922.635000] evbug.c: Event. Dev: isa0060/serio0/input0, Type: 0, Code: 0, Value: 0
[4298923.302000] evbug.c: Event. Dev: isa0060/serio0/input0, Type: 4, Code: 4, Value: 200
[4298923.302000] evbug.c: Event. Dev: isa0060/serio0/input0, Type: 1, Code: 103, Value: 1
[4298923.302000] evbug.c: Event. Dev: isa0060/serio0/input0, Type: 0, Code: 0, Value: 0

To zgleda da je nek log file v /var/log pa nevem kateri. Če bi tole našel, bi lahko naredil program v C++u program ki pretvori to obliko zapisa v berljivo. Kaj je tale modul evbug/evdev? Kako bi našel tole?

Samo za izobraževalne namene seveda

Hvala,
