Service Management Facility

UNIX operating systems have traditionally included a set of services. Services can be described as a software programs not associated with any interactive user login that listen for and respond to request to perform certain tasks, such as webmin service, delivering email, responding to ssh request or permitting command execution.

These services are usually individual applications that executed as a single process that started at boot time and executed continuously while a system was up and running, servicing any request that were received.

Here, I'll show you some of services and how to enable it.
