I would recommend a different fun project. I'm just stumbling on that message, and did not follow the whole thread, sorry if I repeat things already discussed. My point is that Python is able to do surprising things, given the `fcntl' and `ioctl' modules. Surely on Linux, logging keys under X-Windows or under virtual terminals are quite different matters. Let me share a related experience for virtual terminals. I once had to rush the port on Linux a few QNX applications, written in C, which were using the QNX term library for input and display. In console mode, the QNX keyboard is richer than the Linux one. As users wanted to retain the _exact_ keyboard functionality, I saw no choice but reading raw scan codes on the Linux side. So, I wrote a term library emulator as a thin C layer, which was itself using a Python module (Python was to be transparently embedded by the emulated library) for doing the bulk of keyboard processing. It was something pretty heretic to do, I know. But Python was more than fast enough for handling the low-level keyboard reading, for applications otherwise all written in C. But it allowed the port to be done quickly. While debugging such a thing, you often loose the keyboard and with it, the capability of switching terminals, so you have to devise some extra machinery for restoring the keyboard into a usable state. -- François Pinard http://pinard.progiciels-bpi.ca -- http://mail.python.org/mailman/listinfo/python-list

You think this is a suitable beginner project? And for that matter, it doesn't sound like you were doing keylogging, as it is usually understood to mean globally logging keypresses, no matter the application being presented to the user. -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list
Re: keylogger in Python
[Michael Hoffman] You think this is a suitable beginner project? One surely learns a lot! :-) And for that matter, it doesn't sound like you were doing keylogging, as it is usually understood to mean globally logging keypresses, no matter the application being presented to the user. One possible avenue to keylogging might be to start a shell, over the keyboard processing layer, presuming the shell do only simple things over its standard input. But most likely, the shell is playing termios trickery and such things. So one might have to use pty's to get a working solution. Agreed, this is not all evident, and probably too much of a challenge for a beginner. -- François Pinard http://pinard.progiciels-bpi.ca -- http://mail.python.org/mailman/listinfo/python-list

Under AmigaOS, one would inject a key handler at high-priority into the OS input stream chain (a linked list of priority ordered programs that want to see input). The logger would receive, on its input port, an OS packet with the timestamp and key codes, could log it, and then return it to the OS to be passed to the next program in the chain (some programs consume the stream and don't pass it on). It was also easy to inject fake events -- a program could inject, for example, disk-change events that other programs would respond to. On Windows... I don't know for sure... Chapter 27 of Programming Applications for Microsoft Windows 4th Ed. might be of use (may also be a more up-to-date version available too). It shows some system call of AttachThreadInput() being used to link a program's input stream (queue in the book's terminology) to another program so both receive the same data (I think). You're logger would have to hook into the process start-up system so that it could link to every process that might be reading keys. I'd go to http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/windowing/hooks/abouthooks.asp?frame=true#wh_journalrecordhook for starters. Also, if you have a w32 sdk, you likely have the source for an old windows message spy program (in C), along with makefile and bits and pieces it needs. You could cannibalize to do specifically keyboard-oriented stuff, and differentiate alt-stuff from plain stuff etc. You can also monitor the activity of individual widgets and whatnot and copy the messages they receive to change text and resize and all manner of stuff. Try typing spyxx.hlp and see if spy++ help comes up. Or possibly run an older spy.exe for an example of interactively selecting what to monitor. Then you could write a C module to provide a python interface to those capabilities. Have fun ;-) Regards, Bengt Richter -- http://mail.python.org/mailman/listinfo/python-list
keylogger in Python
ok, i thought for 2 seconds i might have created a Keylogger in python but i still have one major think stopping me... PYTHON. when i run the program i have python create a file named keylog2.log and it then logs all keys pressed/typed in the python IDE into that file. All i want to know now is how do i hide or background python so that it will log all the keys pressed outside of Python. feel free to play around with my program... but please post ur findings on my post... # class keylogger: pass keylogging = keylogger() keylog = open(keylog2.log, w) text = raw_input() keylog.write(text) keylog.close keylog = open(keylog2.log, r) keylog.read -- http://mail.python.org/mailman/listinfo/python-list
