Note
BOOTP operation is similar to DHCP, but the resulting IP
parameters will be the same when powered off/on. In
DHCP, IP configuration parameters are leased and may
change over time.
When in its factory-default state and powered on, the HP Jetdirect projector
server will attempt to automatically configure itself using several dynamic
methods, one of which is BOOTP.
BOOTP/TFTP on UNIX
This section describes how to configure the projector server using BOOTP
(Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) services on
UNIX servers. BOOTP and TFTP are used to download network
configuration data from a server to the HP Jetdirect projector server over the
network.
Systems That Use Network Information Service (NIS)
If your system uses NIS, you may need to rebuild the NIS map with the
BOOTP service before performing the BOOTP configuration steps. Refer to
your system documentation.
Configuring the BOOTP Server
For the HP Jetdirect projector server to obtain its configuration data over the
network, the BOOTP/TFTP servers must be set up with the appropriate
configuration files. BOOTP is used by the projector server to obtain entries
in the /etc/bootptab file on a BOOTP server, while TFTP is used to
obtain additional configuration information from a configuration file on a
TFTP server.
When the HP Jetdirect projector server is powered on, it broadcasts a BOOTP
request that contains its MAC (hardware) address. A BOOTP server daemon
searches the /etc/bootptab file for a matching MAC address, and if
successful, sends the corresponding configuration data to the Jetdirect
projector server as a BOOTP reply. The configuration data in the
/etc/bootptab
file must be properly entered. For a description of entries,
