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 print 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 print 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 print 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 print server as a BOOTP reply. The configuration
data in the
/etc/bootptab
file must be properly entered.
For a description of entries, see " Bootptab File Entries ".
The BOOTP reply may contain the name of a configuration file
containing enhanced configuration parameters. If the HP
Jetdirect print server finds such a file, it will use TFTP to
download the file and configure itself with these parameters.
For a description of entries, see "
TFTP Configuration File
Entries ". Configuration parameters retrieved via TFTP are
optional.
Note HP recommends that the BOOTP server be located on
the same subnet as the printers it serves. BOOTP
broadcast packets may not be forwarded by routers
unless the routers are properly configured.
CAUTION Community names (passwords) for your printer
are not secure. If you specify a community name
for your printer, select a name that is different
from passwords used for other systems on your
network.
