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

• apm-scripts/ — This directory contains the APM suspend/resume script. Do not edit the files directly. If customization is necessary, create a file called /etc/sysconfig/apm-scripts/apmcontinue which is called at the end of the script. It is also possible to control the script by editing /etc/sysconfig/apmd.

• 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.

• networking/ — This directory is used by the Network Administration Tool (system-config-network), and its contents should not be edited manually. For more information about configuring network interfaces using the Network Administration Tool, refer to the chapter called Network Configuration in the Red Hat Enterprise Linux System Administration Guide.

• 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 up and down network interfaces, such as ifup and ifdown.

  • Scripts used to bring up and down ISDN interfaces, such as ifup-isdn and ifdown-isdn.

  • Various shared network function scripts which should not be edited directly.

  For more information on the network-scripts directory, refer to Chapter 8 Network Interfaces.

• rhn/ — This directory contains the configuration files and GPG keys for Red Hat Network. No files in this directory should be edited by hand. For more information on Red Hat Network, refer to the Red Hat Network website online at https://rhn.redhat.com/.
