1.The client sends a boot request to the server over port 67. The request is handled by the bootpd daemon on the server. If the client is registered, the /etc/bootptab file is referenced for the boot IP address; if the client is anonymous, DHCP services are used to assign the boot IP address. The server then sends the networking information to the client on port 68. For more information on booting registered Itanium-based clients, see “Configuring the Ignite-UX server for Itanium-based clients” (page 35). For more information on booting anonymous Itanium-based clients, see “Configuring an Ignite server to boot anonymous Itanium-based clients” (page 44). For more information on bootpd, see bootpd(1M).

2.The client sends a boot request to the server over port 1067. The request is handled by the instl_bootd daemon on the server. The /etc/opt/ignite/instl_boottab file is referenced whether the client is registered or anonymous. The server then sends the networking information to the client on port 1068. For more information on booting registered PA-RISC clients, see “Configuring the Ignite-UX server for PA-RISC clients” (page 31). For more information on booting anonymous PA-RISC clients, see “Configuring an Ignite server to boot anonymous PA-RISC clients” (page 43). For more information on instl_bootd, see instl_bootd(1M).
