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.
►zseries: IBM System z do not support USB. The names of the interface files and
network aliases contain System z-specific elements like qeth. ◄
/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. Some of the variables
from /etc/sysconfig/network/config can also be used in ifcfg-* files,
where they are given a higher priority. The /etc/sysconfig/network/ifcfg
.template file lists variables that can be specified in a per interface scope. However,
most of the /etc/sysconfig/network/config variables are global and cannot
be overriden in ifcfg-files. For example NETWORKMANAGER or NETCONFIG_* vari-
ables are global.
/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:
# Destination
#
127.0.0.0
204.127.235.0
default
207.68.156.51
192.168.0.0
The route's destination is in the first column. This column may contain the IP address
of a network or host or, in the case of reachable name servers, the fully qualified network
or hostname.
