30.6.1 Configuration Files

This section provides an overview of the network configuration files and explains their
purpose and the format used.
/etc/syconfig/hardware/hwcfg-*
These files contain the hardware configurations of network cards and other devices.
They contain the needed parameters, such as the kernel module, start mode, and script
associations. Refer to the manual page of hwup for details. Regardless of the existing
hardware, the hwcfg-static-* configurations are applied when coldplug is started.
/etc/sysconfig/network/ifcfg-*
These files contain the configurations for network interface. They include information
such as the start mode and the IP address. Possible parameters are described in the
manual page of ifup. Additionally, all variables from the files dhcp, wireless,
and config can be used in the ifcfg-* files if a general setting should be used for
only one interface.
/etc/sysconfig/network/{config,dhcp
,wireless}
The file config contains general settings for the behavior of ifup, ifdown, and
ifstatus. dhcp contains settings for DHCP and wireless for wireless LAN
cards. The variables in all three configuration files are commented and can also be used
in ifcfg-* files, where they are treated with higher priority.
/etc/sysconfig/network/{routes,ifroute-*}
The static routing of TCP/IP packets is determined here. All the static routes required
by the various system tasks can be entered in the /etc/sysconfig/network/
routes file: routes to a host, routes to a host via a gateway, and routes to a network.
For each interface that needs individual routing, define an additional configuration file:
/etc/sysconfig/network/ifroute-*. Replace * with the name of the inter-
face. The entries in the routing configuration files look like this:
