How To: Servers and Relays

1. Select a server from the System Management console and start DHCP Manager.
   If the server has not been previously configured as either a DHCP server or as a BOOTP relay agent, the Choose Server Configuration dialog box is displayed. You can choose to configure a server as either a DHCP server or as a BOOTP relay agent, but not both.

2. Select Configure as DHCP Server.
   The DHCP Server Configuration Wizard starts.
3. Step through the configuration, providing the information requested.
   When the configuration is completed, the DHCP server starts.

To change any of the configuration parameters, you must first unconfigure the server and then use the Configuration Wizard to reconfigure the server.

To customize DHCP services, select Modify from the Services menu.

1. Select a server from the System Management console and start DHCP Manager.

2. Select Configure as BOOTP Relay.
   The Configure BOOTP Relay dialog box is displayed.
3. Enter DHCP servers.
   Enter the names or IP addresses of one or more DHCP servers to which to relay configuration requests.

When you first configure the DHCP server, the Configuration Wizard configures the first network. To add additional networks, follow these steps.

1. Choose Network Wizard from the Edit menu of the View Addresses window.

3. Click OK.

The DHCP server or BOOTP relay agent starts automatically when you have completed the initial configuration. You can stop or start the service by choosing Stop or Start from the Services menu. This is analogous to running the /etc/init.d/dhcp script with the stop or start command.

   The Unconfigure Service dialog box is displayed.
2. Choose one or both options.
   

   Remove dhcptab and all DHCP network tables	Use this option with caution. If you use NIS+, removing these tables may cause a problem for other DHCP servers that share these databases.
   Remove all hosts table entries for DHCP addresses	Check this box to also remove entries from the server's hosts table.

3. Click OK to confirm your actions.

Unconfigure a BOOTP Relay Agent
