Disabled Services
Ubuntu install a lot of services you might not need. These services take memory and disk space that you might need to use. This section of the guide will help you disable services that are not required to use.
Hardening systems by disabling or removing unnecessary services can enhance security and improve overall system performance. To find out which services are currently running, you can run this command:
sudo initctl list | grep running
To disable services, you can remove the startup script, use a command such as chkconfig, or simply removing it from the system. Most of the services can be disabled by running this command:
echo "manual" > /etc/init/service.override update-rc.d -f service_name remove
Some services can be disabled by overriding the execution:
or by removing it:
sudo apt-get purge service_name
