DHCP Server Configuration

You configure the DHCP server the first time you run DHCP Manager on the system where you want to run the DHCP server. DHCP Manager server configuration dialogs prompt you for essential information needed to enable and run the DHCP server on one network. Some default values are obtained from existing system files. If you have not configured the system for the network, there will be no default values. DHCP Manager prompts for the following information:

• Role of the server, either DHCP server or BOOTP relay agent

• Data storage method, either local files or NIS+

• Length of lease time and whether clients should be able to renew leases

• DNS domain name and IP addresses of DNS servers

• Network address and subnet mask for the first network you want to be configured for DHCP service

• Network type, either LAN or point-to-point

• Router discovery or the IP address of a particular router

• NIS domain name and IP address of NIS servers

• NIS+ domain name and IP address of NIS+ servers

You can also configure the DHCP server using the dhcpconfig command. This utility gathers information from existing system files automatically in order to provide a useful initial configuration. Therefore, you must ensure that the files are correct before running dhcpconfig. See dhcpconfig(1M) for information about the files dhcpconfig uses to obtain information. To make configuration changes after the initial configuration, you must make changes to the system files and rerun dhcpconfig so that it picks up the changes.
