Forwards BOOTP and DHCP packets off the local network.
startsrc -s dhcprd [ -a Argument ] [ -a Argument ] ...
dhcprd [ -f ConfigurationFile ]
The dhcprd daemon listens for broadcast packets, receives them, and forwards them to the appropriate server. This keeps broadcasts from having to be propagated to other networks. The DHCP Relay Agent handles the forwarding the DHCP and BOOTP client broadcast packets off of the local network and on to a set of servers. The initial packets sent by a BOOTP or DHCP client are broadcasts on the local interface of the client machine. These packets are not allowed to be passed through network gateways and routers. So, a BOOTP/DHCP relay agent, the dhcprd daemon, sends these packets to the appropriate servers.
The DHCP Server reads /etc/services file to determine which port it should use for receiving requests. The default service is dhcps. Since this is the same port that the bootpd daemon uses, you can only have one (either dhcprd or bootpd) daemon running. If you choose the dhcprd daemon, you will need to uncomment bootp from the /etc/inetd.conf file, then enter refresh -s inetd on the command line.
Note: If bootpd is running, this program needs to be stopped before starting the daemons.
| -f ConfigurationFile | Specifies the configuration file to be used. The default is the /etc/dhcprd.cnf file. |
