21.3 Manual Network Conﬁguration

Manual conﬁguration of the network software should always be the last al-

ternative. Using YaST is recommended. All network interfaces are activated

with the script /sbin/ifup. To halt the interface, use ifdown. To check its

status, use ifstatus.

If you only use internal network cards, simply conﬁgure the interfaces by

means of their names. With the commands ifup eth0, ifstatus eth0,

and ifdown eth0, start, check, or stop the interface eth0. The respective

conﬁguration ﬁles are stored in /etc/sysconfig/network/ifcfg-

eth0. eth0 is the name of the interface and the name of the conﬁguration.

Alternatively, conﬁgure the network in relation to the hardware

address (MAC address) of a network card. In this case, use a

hardware-based conﬁguration ﬁle named in the format ifcfg-

<hardwareaddresswithoutcolons>. Use lowercase characters in the

hardware address, as displayed by the command ip link (ifconfig

shows uppercase letters). If ifup ﬁnds a conﬁguration ﬁle matching the

hardware address, a possibly existing ifcfg-eth0 ﬁle is ignored.

Things are a little more complicated with hotplug network cards, however.

If you do not use one of those cards, proceed directly to Section 21.3.1 on

page 433.
