LKL Keylogger isn't creating the logfile.

Posted on 2008-10-08
Last Modified: 2013-11-15
I am using Ubuntu 8.04 Hardy Heron.

I have used the package manager to install LKL (-- Linux Key Logger vers 0.1.1 --

It is running, and I have managed to get the keymap to work also.

The problem I am having is that the log file, in this case - keylog.txt is not being created!!
The application shows no errors at all. My system resources even go up when I begin the logging and come down again when I kill it. Below's a copy of my terminal's output.

Any assistance would be LOVELY.

P.S. I'm not hellbent on using LKL, it just seems to be a popular choice.
root@Rambo:~# lkl;

-- Linux Key Logger vers 0.1.1 --
            -h this help
            -l start to log the 0x60 port (keyboard)
            -b Debug Mode.Perhaps it's usefoul :P
            -k <km_file> set a keymap file
            -o <o_file> set an output file
            -m <email> send logs to <email> every 1k
            -t <host> hostname for sendmail server. default is localhost

Example: lkl -l -k keymaps/it_km -o log.file

root@Rambo:~# lkl -l -k /usr/share/lkl/keymaps/us_km -o ~/tmp/keylog.txt

Started to log port 0x60. Keymap is /usr/share/lkl/keymaps/us_km. The logfile is /root/tmp/keylog.txt.

just out of interest, what do you want to log?

It only works with ps2 keyboards. Are you using a usb keyboard?

@ Jools: I want to log ALL keyboard strokes inputted into the workstations.

@Owensleftfoot: I have read that it only works on USB. This is painful. I am using USB throughout, however, if there's no other choice, I'll have to get USB to PS2 adapters so that it can monitor the correct port.

The issue is however, not that the log file's empty, it's simply not there..

Perhaps a better application is available?

We website certainly seems to indicate it logs the hardware port, perhaps it only creates the file once it has detected input...

If that's the case could someone just circumvent it by connecting the keyboard back into the usb port?

Anyway, I'm guessing that there is a security reason for doing this as opposed to using some sort of auditing. Who would have the time to check thru all the logs?? I was wondering if the use of `script` may help but it's a security thing then perhaps not.

It is a small environment with a handful of Estate Agents, so the margin for tampering's almost 0!

It does indeed monitor the hardware port, as apposed to it not being able to monitor the USB Device . I was thinking along the same lines as you with reguards to the lack of input, leading to the lack of the log file, but i've tried with both k/bs.

More and more, i'm thinking that another app is on the cards?

How about just restricting their use, I'm guessing they wont need root access, please god not estate agents!

You could give them a restricted account and use sudo configured for certain functions.

Is key logging a required function or are you just trying to think ahead for when they screw the system up!

Ah jools, I've been grafting at trying to get this to work all day, to say I am annoyed, is a light understatment! Your post, however, has made my day!!

Management are trying to catch people chatting using various IMs. I don't want to go into too much details, but at the end of the day - I need all keystrokes recorded and logged.

The environment is such that funds are not available for a Proxy Server or any sort of decent management system. The owners simply want to be able to read through a log and see who is generating sales and who isn't.

Its normally used to track the keystrokes/passwords/uploads/downloads of hackers on a honeynet

oh dear...I cant swear here but wot a complete bunch of illegitimate children....and you're kinda stuck, poor you!

So, are the PC's all linux based or are the ones the sales people have to use windows based?
Shame, there are a load of hardware options available, but on a bidget of £0 youre a bit stuck.

You could configure Linux to be the proxy.

Just some links...

I'll see if I can find out anything and do a bit of digging around...
