This example configures a machine named capture.my.domain that retrieves its network information through DHCP on interface eth0.

File /etc/hosts contains the following line to ensure a hostname/IP-address mapping for the machine:

127.0.0.1 capture.my.domain capture localhost.localdomain localhost

File /etc/sysconfig/network contains the following line:

HOSTNAME=capture.my.domain

File /etc/sysconfig/network-scripts/ifcfg-eth0 contains only the following lines:

BOOTPROTO=dhcp
DEVICE=eth0
ONBOOT=yes
