D.2. Directories in the /etc/sysconfig/ Directory

The following directories are normally found in /etc/sysconfig/.
This directory contains the configuration files needed to do Class Based Queuing for bandwidth management on network interfaces. CBQ divides user traffic into a hierarchy of classes based on any combination of IP addresses, protocols, and application types.
This directory is used by the Network Administration Tool (system-config-network), and its contents should not be edited manually.
This directory contains the following network-related configuration files:
  • Network configuration files for each configured network interface, such as ifcfg-eth0 for the eth0 Ethernet interface.
  • Scripts used to bring network interfaces up and down, such as ifup and ifdown.
  • Scripts used to bring ISDN interfaces up and down, such as ifup-isdn and ifdown-isdn.
  • Various shared network function scripts which should not be edited directly.
For more information on the /etc/sysconfig/network-scripts/ directory, refer to Chapter 7, Network Interfaces.
