klogger

klogger is a user space keylogger made to run on Linux, although it probably can run on other systems (I haven't tested yet). After doing much research on making a practical keylogger in Linux, I decided to make a user space keylogger rather then a kernel space keylogger. A user space keylogger has the advantages that it can be more portable (doesn't have to be built for a specific kernel) and has fast and easy access to the file system and network.

There are several modifications in the works to klogger which would be nice:

• A way to detect the current keymap (Standard US layout, dvorak, etc...) and choose an appropriate keymap from a set of corresponding keymaps. This would require modifying scancodes.c as it currently only considers a US layout.
• Better PS/2 mouse parsing. Because this program reads from the PS/2 port, it has to ignore the mouse. The logic to do this is currently simple and could definitely be improved.
• Network access. The ability for this program to send it's output to a remote network host would be nice.
• Testing on different operating systems. This program seems like it would be able to work on a variety of UNIX operating systems, but I haven't been able to test it. Any bug reports for other operating systems are welcome.
• Testing for non-PS/2 keyboards. I haven't tested this with USB keyboards so again, bug reports are welcome.
