►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 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:
# 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.
The second column contains the default gateway or a gateway through which a host or
network can be accessed. The third column contains the netmask for networks or hosts
behind a gateway. For example, the mask is 255.255.255.255 for a host behind a
gateway.
The fourth column is only relevant for networks connected to the local host such as
loopback, Ethernet, ISDN, PPP, and dummy device. The device name must be entered
here.
