Bootptab file entries
The following is an example of an
/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”:
A colon (:) indicates the end of a field, and a backslash (\) indicates that the entire entry is
continued on the next line—more fields. 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), and hyphens. The underline character (_) is not allowed. Refer
to your systems documentation for more information.
The configuration data contains tags that identify the various HP Jetdirect parameters and their
settings. The following table describes these tags:
116 8 Networking
EN
Tag
RFC 2132
Option
Description
nodename
_
Name of the peripheral device. Identifies an entry point to a list of
parameters for the specific peripheral device. Must be the first field in an
entry. (In the example above, the
nodename
is
picasso
.)
hn
12
Host name tag. This tag does not take a value but causes the BOOTP
daemon to download the host name to the print server. The host name will
be printed on the Jetdirect configuration page, or returned on an SNMP
sysName request by a network application.
ht
_
Hardware type tag. For this HP Jetdirect print server, set this to ether (for
Ethernet). Must precede the
ha
tag.
vm
_
The BOOTP report format tag (required). Set this tag to
rfc1048
.
ha
_
Hardware address tag. The hardware (MAC) address is the link-level or
station address of the HP Jetdirect print server. It can be found on the
Jetdirect configuration page as the Hardware Address, and also printed on a
label attached to the print server. The
ht
tag must precede this tag.
ip
_
IP address tag (required). This will be the print server's IP address.
sm
1
Subnet mask tag. The subnet mask will be used by the print server to
identify the portions of an IP address that specify the network/subnetwork
number and the host address.
gw
3
Gateway IP address tag. This address identifies the IP address of the default
gateway (router) that the HP Jetdirect print server will use for
communications with other subnets.
ds
6
DNS (Domain Name System) server’s IP address tag. Only a single name
server can be specified.
dn
15
Domain name tag. Specifies the domain name for the print server (for
example, support.hp.com). It does not include the host name—it is not the
Fully Qualified Domain Name (such as printer1.support.hp.com).
ef
18
Extensions file tag that specifies the relative path name of the TFTP
configuration file. This tag is similar to the vendor-specific tag T144.
na
44
Tag for IP addresses of the NetBIOS-over-TCP/IP Name Server (NBNS). A
primary and secondary server may be specified in order of preference.
lease-time
51
DHCP IP address lease duration time (seconds).
tr
58
DHCP T1 timeout, specifying the DHCP lease renewal time (seconds).
tv
59
DHCP T2 timeout, specifying the DHCP lease rebind time (seconds).
EN
Using BOOTP 117
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.
lg
7
syslog server’s IP address tag. It specifies the server to which the print
server sends syslog messages.
T144
_
An HP-proprietary tag that specifies the relative path name of the TFTP
configuration file. Long path names may be truncated. The path name must
be in double quotes (“pathname”). For file format information, refer to the
TFTP file entries below. Note that standard BOOTP RFC-2132 option 18
(extensions file path) also allows the standard tag ef to specify the relative
path name of the TFTP configuration file.
T145
_
Idle Timeout option. An HP-proprietary tag to set the idle timeout (seconds),
which is the amount of time that a print data connection may remain idle
before being closed. The range is 1–3600 seconds.
T146
_
Buffer Packing option. An HP-proprietary tag to set buffer packing for TCP/IP
packets:
0: (default) Normal, data buffers are packed before sending to the printer.
1: Disable buffer packing, data is sent to the printer when received.
T147
_
Write Mode option. An HP-proprietary tag that controls the TCP PSH flag
setting for device-to-client data transfers:
0: (default) Disables this option, flag not set.
1: All-push option. Push bit is set in all data packets.
2: EOI-push option. Push bit is set only for data packets that have an
End-of-Information flag set.
T148
_
IP Gateway Disable option. An HP-proprietary tag to prevent configuration of
a gateway IP address:
0: (default) Allows a gateway IP address.
1: Prevents a Gateway IP address from being configured.
T149
_
Interlock Mode option. An HP-proprietary tag that specifies whether an
acknowledgement (ACK) on all TCP packets is required before the printer is
allowed to close a Port 9100 print connection.
T150
_
TFTP server’s IP address option. An HP-proprietary tag to specify the IP
address of the server where the TFTP configuration file is located.
T151
_
Network configuration option. An HP-proprietary tag to ensure other
dynamic configuration methods are not used:
BOOTP-ONLY: Send BOOTP requests only, not DHCP.
DHCP-ONLY: Send DHCP requests only, not BOOTP.
