Bootptab file entries
The following is an example of a
/etc/bootptab
file entry for
an HP JetDirect print server:
picasso:\
:hn:\
:ht=ether:\
:vm=rfc1048:\
:ha=0001E6123456:\
:ip=192.168.45.39:\
:sm=255.255.255.0:\
:gw=192.168.40.1:\
:lg=192.168.40.3:\
:T144=“hpnp/picasso.cfg”:
Note that the configuration data contains tags that identify the
various HP JetDirect parameters and their settings. The following
table describes these tags.
Tag
Description
nodename
The name of the peripheral. This is an entry point to a list of parameters for a
specific peripheral. This must be the first tag in an entry. (In the example, the
nodename
is
picasso
.)
hn
The host name tag. This tag does not take a value, but it causes the BOOTP
daemon to download the host name to the HP JetDirect print server. The
host name is printed on the HP JetDirect configuration page or a network
application returns the host name on an SNMP sysName request.
ht
The hardware type tag. For the HP JetDirect print server, set this tag to
ether
(for Ethernet) or
token
(for Token Ring). This tag must precede the
ha
tag.
vm
The BOOTP report format tag (required). Set this tag to
rfc1048
.
ha
The hardware address tag. The hardware (MAC) address is the HP JetDirect
print server’s link-level or station address. You can find this address on the
HP JetDirect configuration page as the Hardware Address. On
HP JetDirect external print servers, this address is also printed on a label
attached to the print server.

Using BOOTP 53
Use the following conventions for the bootptab file entries:
●
A colon (:) indicates the end of a field.
●
A backslash (\) indicates that the entry is continued on the
next line.
●
Spaces are 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 (for domain
names only), or hyphens.
●
The underscore character (_) is not allowed.
See your system documentation or online help for more
information.
ip
The IP address tag (required). This is the HP JetDirect print server’s IP
address.
gw
The gateway IP address tag. This is the IP address of the default gateway
(router) that the HP JetDirect print server uses to communicate with other
subnets.
sm
The subnet mask tag. The HP JetDirect print server uses the subnet mask to
identify the portions of an IP address that specify the network and
subnetwork number and the host address.
lg
The syslog server’s IP address tag. This is the address of the server where
the HP JetDirect print server sends syslog messages.
T144
A vendor-specific tag that specifies the relative path name of the TFTP
configuration file. You can truncate long path names. The path name must be
enclosed with quotes (for example, “pathname”). See
Using DHCP
for more
information about file formats.
Note
Standard BOOTP option 18 (extensions file path) also allows a standard tag
(
ef
) to specify the relative path name of the TFTP configuration file.
T150
The TFTP server’s IP address tag.
T151
A BOOTP-only tag. You must specify
BOOTP-ONLY
to ensure that other
dynamic configuration methods, such as DHCP, are not used.
