LogKeys: Monitor Keyboard Keystrokes in Linux

If you need to monitor keyboard activity on a Linux system, LogKeys is a go-to open-source solution. It’s lightweight, easy to use, and works across most Linux distributions. Here’s what you need to know about getting started with LogKeys, its features, and why you might use it.

What Is LogKeys?

LogKeys is a simple keylogger for Linux. It records every keystroke made on the system and saves the data to a log file. Unlike some commercial keyloggers, LogKeys is open source and designed for transparency. It works from the terminal and doesn’t bog down your system.

Why Monitor Keystrokes?

There are legitimate reasons to monitor keyboard activity:

• Parental controls: Keep tabs on what’s being typed and searched by minors.
• Security auditing: Track potential unauthorized activity on shared systems.
• Productivity monitoring: See how devices are being used in business or educational settings.

Warning: Logging keystrokes can collect sensitive personal information, including passwords. Always get proper permission before installing and running keyloggers. Unauthorized use is illegal and unethical.

Installing LogKeys

Getting LogKeys up and running is straightforward on most Linux distros.

1. Install required dependencies:
   sudo apt-get install g++ make autoconf automake pkg-config libtool
2. Clone LogKeys from GitHub:
   git clone https://github.com/kernc/logkeys.git
cd logkeys
3. Compile LogKeys:
   ./autogen.sh
./configure
make
sudo make install

How to Use LogKeys

Start logging keystrokes with a single command. You’ll need root permissions:

sudo logkeys --start --output /path/to/logfile.log

To stop logging:

sudo logkeys --kill

You can view the logged keystrokes by opening the output file:

cat /path/to/logfile.log

Features and Options

• Language layouts: Supports multiple keyboard layouts with the --layout option.
• Silent mode: Runs quietly in the background.
• Custom log file location: Choose where your logs are stored.
• Session-specific logging: Limit logging to specific sessions or times.

Check all available options with:

logkeys --help

Ethical Use and Privacy

Always inform users if you plan to monitor a device. Keyloggers like LogKeys should only be used for legitimate, ethical, and legal purposes. Misuse can result in severe consequences.

Conclusion

LogKeys offers a straightforward way to monitor keyboard activity on Linux. Whether you’re a system administrator, security professional, or a parent, LogKeys provides the transparency and control you need—without unnecessary bloat.
