A. You need to set the PERSISTENT_DHCLIENT option by editing Ethernet configuration file. This option is turned off by default. Login as the root user Open /etc/sysconfig/network-scripts/ifcfg-eth0 file to set eth0 to persistently look for an IP address lease: # vi /etc/sysconfig/network-scripts/ifcfg-eth0 Append line PERSISTENT_DHCLIENT=1, at the end configuration should look as follows: DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp PERSISTENT_DHCLIENT=1 Save and close the file. Restart networking service or reboot laptop / desktop to test the changes: # /etc/init.d/networking restart Please note that your network switches and other protocol may need to configure properly to work with this option.
