Migrate to GRUB 2
The tools used to boot Linux are changing. Specifically, the Grand Unified Bootloader (GRUB) is now officially in maintenance mode only, and GRUB's developers have abandoned the original GRUB in favor of an entirely rewritten package, known as GRUB 2. Discover GRUB 2's new capabilities and how to use it.

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): NetBIOS and WINS
Naming is unusual in SMB/CIFS networks. Although modern clients can use Internet domain names to refer to each other, older clients relied on a Microsoft-specific system known as the Windows Internet Name Service (WINS) server, or the NetBIOS Name Server (NBNS); the two terms are synonymous. Configuring Samba properly for name resolution is therefore important. So is configuring browsing, which is the mechanism by which servers learn what shares are available on specific servers.

Learn Linux, 302 (Mixed environments): CIFS integration
In addition to, or instead of, functioning as a server on a Windows network, a Linux computer can function as a client. You can use an ftp-like program to transfer files and modify a server, or you can mount a share from a Samba or Windows Server machine on your Linux computer, giving normal programs the ability to access files directly on the server. When doing so, though, keep in mind the characteristics of the original SMB protocol and its newer CIFS variant, particularly when accessing a Windows Server machine: You may not have access to all the file system features that a Linux computer supports.

Recover from a failed Linux boot
If your Linux computer fails to boot after a kernel upgrade, disk swap, or other system change, you're not helpless. The Grand Unified Bootloader (GRUB) gives you ways to control the boot process and recover. Or, if necessary, emergency boot disks that you create with an external tool can come to the rescue. Learn procedures and GRUB commands that can help you boot in problem situations, and find out about a life-saving external tool for BIOS-based systems.

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.
