Create the file /etc/dhcp/dhclient.conf, and add an
appropriate setting for each of the ten configuration settings which can be
obtained via DHCP. For each setting, do one of the following:
If the setting should not be configured remotely by the DHCP server,
select an appropriate static value, and add the line:
supersede setting value;
If the setting should be configured remotely by the DHCP server, add the lines:
request setting;
require setting;
For example, suppose the DHCP server should provide only the IP address itself
and the subnet mask. Then the entire file should look like:
supersede domain-name "example.com";
supersede domain-name-servers 192.168.1.2;
supersede nis-domain "";
supersede nis-servers "";
supersede ntp-servers "ntp.example.com ";
supersede routers 192.168.1.1;
supersede time-offset -18000;
request subnet-mask;
require subnet-mask;
