Operation Manual

In the IPv6 Protocol Settings choose whether you want to use the IPv6 protocol. It is
possible to use IPv6 together with IPv4. By default, IPv6 is activated. However, in
networks not using IPv6 protocol, response times can be faster with IPv6 protocol dis-
abled. If you want to disable IPv6, uncheck the Enable IPv6 option. This disables au-
toload of the kernel module for IPv6. This will be applied after reboot.
In the DHCP Client Options congure options for the DHCP client. The DHCP Client
Identier must be different for each DHCP client on a single network. If left empty, it
defaults to the hardware address of the network interface. However, if you are running
several virtual machines using the same network interface and, therefore, the same
hardware address, specify a unique free-form identier here.
The Hostname to Send species a string used for the hostname option eld when dhcpcd
sends messages to DHCP server. Some DHCP servers update name server zones (forward
and reverse records) according to this hostname (Dynamic DNS). Also, some DHCP
servers require the Hostname to Send option eld to contain a specic string in the
DHCP messages from clients. Leave AUTO to send the current hostname (that is the
one dened in /etc/HOSTNAME). Leave the option eld empty for not sending any
hostname. If yo do not want to change the default route according to the information
from DHCP, uncheck Change Default Route via DHCP.
Changing the Conguration of a Network Card
To change the conguration of a network card, select a card from the list of the detected
cards in Network Settings > Overview in YaST and click Edit. The Network Card Setup
dialog appears in which to adjust the card conguration using the General, Address
and Hardware tabs. For information about wireless card conguration, see Section 32.5,
“Conguration with YaST” (page 519).
Conguring IP Addresses
You can set the IP address of the network card or the way its IP address is determined
in the Address tab of the Network Card Setup dialog. Both IPv4 and IPv6 addresses are
supported. The network card can have No IP Address (which is useful for bonding de-
vices), a Statically Assigned IP Address (IPv4 or IPv6) or a Dynamic Address assigned
via DHCP or Zeroconf or both.
If using Dynamic Address, select whether to use DHCP Version 4 Only (for IPv4),
DHCP Version 6 Only (for IPv6) or DHCP Both Version 4 and 6.
