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

The following directories are normally found in /etc/sysconfig/.

/etc/sysconfig/cbq/

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.

/etc/sysconfig/networking/

This directory is used by the Network Administration Tool (system-config-network), and its contents should not be edited manually.

/etc/sysconfig/network-scripts/

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.
