Editing Configuration Files
In this video we learn how to configure services, what kind of configuration files we find /etc, and how config files, subdirectories and include statements all fits together. We also get some first hands-on experience modifying a service. - Learn the difference between a configuration file and a unit file. We will also learn what we configure with the configuration files for the different services. - Add a warning messages to the SSH daemon, telling people what unauthorized access is prohibited. - Then, before we actually restart the SSH daemon we learn a very important lesson to not lock us out from our own server by mistake. We then restart the service and log back into the machine again.
