The list of default services that are enabled at boot can vary depending on the specific Linux distribution and version, as well as the system configuration. However, here are some common Linux services that are typically enabled at boot by default:
- systemd: Systemd is a system and service manager that is the default init system in most modern Linux distributions.
- sshd: The SSH daemon provides secure remote shell and file transfer services.
- cron: Cron is a time-based job scheduler that runs tasks at specific intervals.
- syslog/rsyslog: The syslog or rsyslog service is responsible for system logging.
- network: The network service is responsible for network configuration and management.
- ntpd/chronyd: Ntpd or chronyd is responsible for time synchronization with a time server.
- cupsd: The CUPS daemon provides printer services.
- udev: Udev is a device manager that creates device files in the /dev directory.
- dbus: D-Bus is a message bus system that enables inter-process communication.
- avahi-daemon: Avahi daemon provides zero-configuration networking services.
The exact list of services enabled at boot can be viewed by running the appropriate command for your Linux distribution. For example, on a system using systemd, the following command will show the status of all services:
systemctl status
This will display a list of all services that are currently enabled, along with their status. You can use the systemctl command to start, stop, enable, or disable services as needed.
