Appendix H. Other Technical Documentation
anacondaand Red Hat Enterprise Linux systems use a common set of software components. For detailed information on key technologies, refer to the Web sites listed below:
- Boot Loader
- Red Hat Enterprise Linux uses the
GRUBboot loader. Refer to http://www.gnu.org/software/grub/ for more information.
- Disk Partitioning
- Red Hat Enterprise Linux uses
partedto partition disks. Refer to http://www.gnu.org/software/parted/ for more information.
- Storage Management
- 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.
- Audio Support
- 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/.
- Graphics System
- Both the installation system and Red Hat Enterprise Linux use the
Xorgsuite to provide graphical capabilities. Components of
Xorgmanage the display, keyboard and mouse for the desktop environments that users interact with. Refer to http://www.x.org/ for more information.
- Remote Displays
- Red Hat Enterprise Linux and
anacondainclude 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.
- Command-line Interface
- By default, Red Hat Enterprise Linux uses the GNU
bashshell 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/.
- Remote System Access
- 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
anacondamay use the
scpfeature of OpenSSH to transfer crash reports to remote systems. Refer to the OpenSSH Web site for more information: http://www.openssh.com/.
- Access Control
- 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
netfilterframework to provide firewall features. The Netfilter project website provides documentation for both
netfilter, and the
iptablesadministration facilities: http://netfilter.org/documentation/index.html.
- Software Installation
- Red Hat Enterprise Linux uses
yumto 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.
