Key Logging<\/strong>\u00a0is the process of storing keystrokes with\/without the knowledge of user. Keylogging can be hardware based as well as software based. As clear from the name, a hardware based keylogger does not depends upon any software and keystroke logging is done at hardware level itself. Whereas a software based keylogger depends upon a special software for keylogging.<\/p>\n

There are number of keylogger software applications for almost all the platforms be it\u00a0Windows<\/strong>,\u00a0Mac<\/strong>,\u00a0Linux<\/strong>. Here we are throwing light on an application package called\u00a0Logkeys<\/strong>.<\/p>\n

What is Logkeys?<\/h3>\n

Logkey<\/strong>s is a Linux keylogger. It is more updated than any other available keylogger, Moreover logkeys don\u2019t crash the\u00a0X server,<\/strong>\u00a0and appears to work in all the situations. Logkeys creates a log of all characters and function keys. Moreover logkeys are aware of\u00a0Alt<\/strong>\u00a0and\u00a0Shift<\/strong>\u00a0and works well with serial as well as\u00a0USB<\/strong>\u00a0keyboards.<\/p>\n

There are a lot of keyloggers available for\u00a0Windows<\/strong>\u00a0but this is not the case with\u00a0Linux<\/strong>. Logkeys is not better than any other keylogger application for Linux but certainly it is more updated than other.<\/p>\n

Installation of Logkeys in Linux<\/h3>\n

If you\u2019ve ever installed a Linux tarball packages from source, then you can easily install logkeys package. If you haven\u2019t ever installed a package in Linux from source yet, then you need to install some missing packages like\u00a0C++<\/strong>\u00a0compilers and\u00a0gcc<\/strong>\u00a0libraries before proceeding for installation from source.<\/p>\n

$ sudo apt-get install build-essential\t\t[on Debian<\/strong> based systems]<\/pre>\n
# yum install gcc make gcc-c++\t\t\t[on RedHat<\/strong> based systems]<\/pre>\n
Let\u2019s proceed for the installation, first grab the latest logkeys source package using\u00a0wget command<\/a>\u00a0or use git to clone it as shown:<\/p>\n
-------------------- Download Source Package --------------------<\/strong> \r\n$ wget https:\/\/github.com\/kernc\/logkeys\/archive\/master.zip\r\n$ unzip master.zip  \r\n$ cd logkeys-master\/   \r\n\r\nOR\r\n\r\n-------------------- Use Git to Clone --------------------<\/strong> \r\n$ git clone https:\/\/github.com\/kernc\/logkeys.git\r\n$ cd logkeys\r\n<\/pre>\n
Now build and install logkeys.<\/p>\n
$ .\/autogen.sh\r\n$ cd build         \r\n$ ..\/configure\r\n$ make\r\n$ sudo make install \r\n<\/pre>\n
Now run the\u00a0locale-gen<\/strong>.<\/p>\n
$ sudo locale-\u00adgen<\/pre>\n
Sample Output<\/h5>\n

Usages of logkeys<\/h4>\n
    \n
  1. logkeys \u00ads<\/strong>\u00a0: Start logging keypress.<\/li>\n
  2. logkeys \u00adk<\/strong>\u00a0: Kill logkeys process.<\/li>\n<\/ol>\n
    For detailed information of logkeys usages option, you can always refer to.<\/p>\n
    # logkeys \u2013help\r\n\r\nor\r\n\r\n# man logkeys<\/pre>\n
    Starting the application logkeys using the following command.<\/p>\n
    $ sudo logkeys \u00ad-s<\/pre>\n
    Now running a lot of commands.<\/p>\n
    # ls\r\n# pwd\r\n# ss\r\n# ifconfig<\/pre>\n
    Terminate the process logkeys.<\/p>\n
    # logkeys -k<\/pre>\n
    Check the log file which by default is \u2018\/var\/log\/logkeys.log<\/strong>\u2018.<\/p>\n
    # nano \/var\/log\/logkeys.log<\/pre>\n
    \n
    \"Keyboard<\/a><\/p>\n
    LogKey Logs<\/p>\n<\/div>\n
    To uninstall logkeys, remove all scripts and manuals:<\/p>\n
    $ sudo make uninstall # in the same build dir\r\n<\/pre>\n
    Future Developments Planned<\/h4>\n
      \n
    1. To add support for sending logs via email<\/li>\n
    2. To add support for logging clipboard content<\/li>\n
    3. To add support for mouse event\/mouse click event<\/li>\n<\/ol>\n
