NET 4000 Chapter Notes - Chapter 6.1.4: Superuser, System Administrator
Document Summary
User accounts control the ability to log on to a system, access resources, and perform certain actions. Groups provide a means of grouping users for administrative purposes such as assigning permissions to files. Be aware of the following types of users and groups: Standard user accounts can log into the system. Have friendly usernames (such as mary or bkaun). Have an id of 500 or more (on some distributions) or 1000 or more (on other distributions). System user accounts are created by default during the linux installation and are used by the system for specific roles. Have names that correspond with their roles, such as ftp and mail. Cannot be used to log into the system. Have an id of 500 or less (on some distributions), or 1000 or less (on other distributions). The id is automatically assigned by the system when the account is created.
