Chapter 8: Linux Servers on the LAN. What Is Linux. Linux is a UNIX-like open source operating system. Open source software is software in which the source code is available.
A specific collection of Linux and programs that run on Linux is known as a distribution. Anyone can create their own Linux distribution with enough time and effort.
Several popular distributions are:
RedHat Enterprise Linux. Subscription-based, includes support. Targeted at large corporate LANs. Aims to replace traditional UNIX vendors.
RedHat Fedora. Development branch of Redhat Enterprise Linux used to test new software. Freely available, but less stable than the Enterprise version.
Debian. Freely available and highly stable Linux distribution. Does not include the very newest versions of software, only those versions that have proven stable.
Novell SUSE. Novell’s Linux distribution. Integrated closely with the Novell network operating system. Subscription based.
Mandrake. Popular beginner distribution of Linux. Freely available.
