Worry-free Linux power-downs with Anacron
Linux ordinarily uses Cron to automatically perform routine system maintenance, such as rotating log files and updating spam filtering rules. This works well for servers and other systems that are powered on 24/7. If, however, you want to save power by shutting off the computer when it's not in use, as is common for desktop and laptop systems, Cron can't run. Not running Cron routinely can result in monstrously large log files and other problems. The Anacron utility provides a solution, enabling the computer to run regular maintenance jobs whenever the computer is powered on, even if those times are unpredictable.

Learn Linux, 302 (Mixed environments): Samba roles
Samba isn't a single program; rather, it's a series of interrelated servers and utilities, each of which has its own specific purpose. Understanding the differences between these servers and utilities will help you manage your Samba system. Furthermore, Samba implements a number of different security models, which you must understand to properly integrate Samba into an existing network or to set up a new network with Samba servers at its core.

Learn Linux, 302 (Mixed environments): Install and upgrade Samba
Like most software, Samba must be installed before it can be used. Several methods of doing this exist, but they fall into two broad categories: compiling and installing from source code and installing pre-built binary packages. The former is the more difficult but also more flexible option, while the latter is quite easy on most Linux distributions but locks you into the decisions your distribution maintainer has made concerning supported versions, patches applied, compile-time options enabled, and so on.

Learn Linux, 302 (Mixed environments): Domain control
In SMB/CIFS parlance, a domain is similar to a workgroup: It's a collection of related computers, typically existing on a single local network. A domain, however, features a special computer known as a domain controller that manages logons for all the servers in the domain. It also provides a few additional services. Samba can function as a domain controller, but you need to set several Samba options for it to do so.
