Services and daemons in Linux
In the realm of Linux operating systems, daemons are a fundamental component that runs quietly in the background, silently executing essential tasks without the direct involvement of an interactive user. These processes are traditionally identified by their names ending with the letter d, such as sshd for the Secure Shell (SSH) daemon and httpd for the web server daemon. They play a vital role in handling system-level tasks crucial for both the operating system and the applications running on it.
Daemons serve an array of purposes, ranging from file serving, web serving, and network communications to logging and monitoring services. They are designed to be autonomous and resilient, starting at system boot and running continuously until the system is shut down. Unlike regular processes initiated and controlled by users, daemons possess distinct characteristics:
- Background operation:
- Daemons operate in the background
- They lack a controlling terminal...
