Unit 10: Servers

z z server_identifier [address]: This option defines the IP address of the server that is sent to Notes
clients. By default, the address of the server’s network interface is used, so this should be
used only if the server presents an incorrect address for some reason.
z z server_name [“name”]: This option defines the host name of the server.

z z use_host_dec1_name [true|false: This option defines whether the server will send the
name provided on the host statement to the client as its host name.
z z use_lease_addr_for_default_route [true|false]: This option sends the client its own address
as the default route instead of sending the true default route.
The previous statements deal with how the server operates; however, there are more configuration
options available for client operation. Some of the more common options are as follows:
z z option broadcast_address [address]: Defines the broadcast address.
z z option domain_name [“domain”]: Defines the domain name.
z z option domain_name_servers [address_list]: Lists the addresses of the DNS name servers.

z z option finger_server [address_list]: Lists the finger servers available to the client. Finger
servers are typically used on sites that block finger traffic at the firewall.
z z option host_name [“name”]: Defines the client’s host name.
z z option nis_domain [“name”]: Defines the name of the local NIS (Network Information
Services) domain.

z z option nis_servers [address_list]: Lists the addresses of the NIS servers.
z z option nntp_server [address_list]: Lists the addresses of the NNTP servers the client is to
use.
z z option ntp_servers [address_list]: Lists the addresses of the NTP (Network Time Protocol)
servers the client is to use.

z z option pop_server [address_list]: Lists the addresses of the POP3 servers the client is to use.
z z option routers [address_list]: Defines the default router.
z z option smtp_server [address_list]: Lists the addresses of the SMTP servers the client is to
use.

z z option subnet_mask [mask]: Defines the subnet mask. If this option is undefined, the
network mask from the subnet statement is used.
z z option time_offset [value]: Defines the offset from Coordinated Universal Time of your
time zone (i.e., _5 would mean Eastern Standard Time).

z z option www_server [address_list]: Lists the addresses of the Web servers available to the
client.
Classically, this would be used to define proxy Web servers the client is to use. There are many
more configurable client options than those listed, but these are the ones most commonly used.
For a full list of available options, please read the man pages for dhcpd.conf and dhcp_options.
