Preparing for Linux memory acquisition

Since some commonly used Linux memory extraction tools require a kernel module to be loaded, you need to build this module in a similar environment to the real one. To do this, you can build the module on a prepared virtual machine. You can create such a machine using VMWare, VirtualBox, or other similar solutions. The most important thing is to have the same operating system distribution with the same kernel version as the target host installed on the virtual machine. Therefore, the first step in preparing a virtual environment is to determine the distribution and exact kernel version of the target host. To determine the distribution, run the following command in the terminal on the target host:

$ cat /etc/*-release

To get the exact kernel version, run the following command:

$ uname -r 

You should get the following output:

We now know that Ubuntu...
