Appendix H. Other Technical Documentation

Red Hat Enterprise Linux uses the GRUB boot loader. Refer to http://www.gnu.org/software/grub/ for more information.

Red Hat Enterprise Linux uses parted to partition disks. Refer to http://www.gnu.org/software/parted/ for more information.

Logical Volume Management (LVM) provides administrators with a range of facilities to manage storage. By default, the Red Hat Enterprise Linux installation process formats drives as LVM volumes. Refer to http://www.tldp.org/HOWTO/LVM-HOWTO/ for more information.

The Linux kernel used by Red Hat Enterprise Linux incorporates PulseAudio audio server. For more information about PulseAudio, refer to the project documentation: http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/.

Both the installation system and Red Hat Enterprise Linux use the Xorg suite to provide graphical capabilities. Components of Xorg manage the display, keyboard and mouse for the desktop environments that users interact with. Refer to http://www.x.org/ for more information.

Red Hat Enterprise Linux and anaconda include VNC (Virtual Network Computing) software to enable remote access to graphical displays. For more information about VNC, refer to the documentation on the RealVNC Web site: http://www.realvnc.com/support/documentation.html.

By default, Red Hat Enterprise Linux uses the GNU bash shell to provide a command-line interface. The GNU Core Utilities complete the command-line environment. Refer to http://www.gnu.org/software/bash/bash.html for more information on bash. To learn more about the GNU Core Utilities, refer to http://www.gnu.org/software/coreutils/.

Red Hat Enterprise Linux incorporates the OpenSSH suite to provide remote access to the system. The SSH service enables a number of functions, which include access to the command-line from other systems, remote command execution, and network file transfers. During the installation process anaconda may use the scp feature of OpenSSH to transfer crash reports to remote systems. Refer to the OpenSSH Web site for more information: http://www.openssh.com/.

SELinux provides Mandatory Access Control (MAC) capabilities that supplement the standard Linux security features. Refer to the SELinux Project Pages for more information: http://www.nsa.gov/research/selinux/index.shtml.

The Linux kernel used by Red Hat Enterprise Linux incorporates the netfilter framework to provide firewall features. The Netfilter project website provides documentation for both netfilter, and the iptables administration facilities: http://netfilter.org/documentation/index.html.

Red Hat Enterprise Linux uses yum to manage the RPM packages that make up the system. Refer to http://yum.baseurl.org/ for more information.

Virtualization provides the capability to simultaneously run multiple operating systems on the same computer. Red Hat Enterprise Linux also includes tools to install and manage the secondary systems on a Red Hat Enterprise Linux host. You may select virtualization support during the installation process, or at any time thereafter. Refer to the Red Hat Enterprise Linux Virtualization documentation available from https://access.redhat.com/documentation/en/red-hat-enterprise-linux/ for more information.
