Systems using network information service (NIS)
If your system uses NIS, you might need to rebuild the NIS map with the BOOTP service before
performing the BOOTP configuration steps. See your system documentation.
Configure the BOOTP server
For the HP Jetdirect print server to obtain its configuration data over the network, the BOOTP/TFTP
servers must have the appropriate configuration files. The print server uses BOOTP to obtain entries
in the
/etc/bootptab
file on a BOOTP server. It uses TFTP to obtain additional configuration
information from a configuration file on a TFTP server.
When the HP Jetdirect print server is turned 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 HP Jetdirect print
server as a BOOTP reply. The configuration data in the
/etc/bootptab
file must be correct. For a
description of entries, see Bootptab file entries (IPv4) on page 23 .
The BOOTP reply can contain the name of a configuration file that stores enhanced configuration
parameters. If the HP Jetdirect print server finds such a file, it uses TFTP to download the file and
configure itself using the parameters. For a description of the entries, see
TFTP configuration file
entries (IPv4) on page 25 . Configuration parameters retrieved through TFTP are optional.
NOTE: HP recommends that the BOOTP server be located on the same subnet as the printers it
serves. Routers that are incorrectly configured might not forward BOOTP broadcast packets.
Bootptab file entries (IPv4)
The following is an example of a
/etc/bootptab
file entry for IPv4 configuration of an HP Jetdirect
print server:
picasso:\
:hn:\
:ht=ether:\
:vm=rfc1048:\
:ha=0001E6123456:\
:ip=192.168.40.39:\
:sm=255.255.255.0:\
:gw=192.168.40.1:\
:lg=192.168.40.3:\
:T144="hpnp/picasso.cfg":
The configuration data contains tags to identify the various HP Jetdirect parameters and their
settings.
●
Colon (:): End of a field.
●
Backslash (\): Entry is continued on the next line.
●
Space: Not allowed between the characters on a line.
●
Names (such as host names): Must begin with a letter and can contain only letters, numbers,
periods (domain names), or hyphens.
●
Underline: Not allowed.
