The Linux system provides a framework for loadable modules which can add or remove certain functionality without the need for a restart. In this lab, you will be tasked with installing and removing kernel modules, as well as displaying additional information about them.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Get a Count of the Current Installed Modules and Save It to /root/current_count.txt
Display all the loaded modules:
lsmodSave the count of all the loaded modules to
/root/current_count.txt:lsmod | wc -l > /root/current_count.txt- Remove the target_core_mod Module and All Its Dependencies
To remove the
target_core_module, theiscsi_target_moddependency must be removed (the-voption can be used to display additional information):modprobe -r iscsi_target_modValidate the modules have been removed:
lsmod | grep target- Install the nfsd Module
Install the
nfsdmodule using themodprobecommand (the-voption can be used to display additional information):modprobe -v nfsdValidate that the module was loaded:
lsmod | grep nfsd- Display the Dependencies for the nfsd Module and Save the Names to /root/dependencies.txt
Display information for the
nfsdmodule:modinfo nsfdSave the names of the dependencies to
/root/dependencies.txt:modinfo nfsd | grep depends > /root/dependencies.txt- Get a Final Count of the Modules and Save It to /root/updated_count.txt
Add the output from
lsmod | wc -lto the/root/updated_count.txtfile:lsmod | wc -l > /root/updated_count.txt
