13.4.1.4 Conguring Hostname and DNS
If you did not change the network conguration during installation and the wired card
was already available, a hostname was automatically generated for your computer and
DHCP was activated. The same applies to the name service information your host needs
to integrate into a network environment. If DHCP is used for network address setup,
the list of domain name servers is automatically lled with the appropriate data. If a
static setup is preferred, set these values manually.
To change the name of your computer and adjust the name server search list, proceed
as follows:
1
Go to the Network Settings > Hostname/DNS tab in the Network Devices module in
YaST.
2
Enter the Hostname and, if needed, the Domain Name. The domain is especially
important if the machine is a mail server. Note that the hostname is global and applies
to all set network interfaces.
If you are using DHCP to get an IP address, the hostname of your computer will be
automatically set by the DHCP. You may want to disable this behavior if you connect
to different networks, because they may assign different hostnames and changing
the hostname at runtime may confuse the graphical desktop. To disable using DHCP
to get an IP address uncheck Change Hostname via DHCP.
Assign Hostname to Loopback IP associates your hostname with 127.0.0.2
(loopback) IP address in /etc/hosts. This is an useful option if you want to have
the hostname resolvable at all times, even without active network.
