Bootptab file entries (IPv4)

Bootptab file entries (IPv4)


The following is an example of a /etc/bootptab file entry for IPv4 configuration of an HP Jetdirect print server:

HP Jetdirect Print Servers booptab Bootptab file entries (IPv4)

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.

Entries and tags supported by the HP Jetdirect print serer are listed in the following table:


Tags supported in a BOOTP/DHCP boot file
Item
RFC 2132 Option
Description
nodename
Peripheral name. Identifies an entry point to a list of parameters for a specific peripheral. Must be the first field in an entry. (In the example, nodename is picasso.)
ht
Hardware type. For the HP Jetdirect print server, set this to ether (for Ethernet). Must precede the ha tag.
vm
BOOTP report format (required). Set this to rfc1048.
ha
Hardware address. The media access control (MAC) address or hardware address, which is displayed on the HP Jetdirect configuration page as the HARDWARE ADDRESS. Must be preceded by the ht tag.
ip
IP address tag (required) of the HP Jetdirect print server.
sm
1
Subnet mask. Used by the HP Jetdirect print server to identify the portions of an IP address that set the network/subnetwork number and the host address.
gw
3
Gateway IP address. The IP address of the default gateway (router) that the HP Jetdirect print server uses for communication with other subnets.
ds
6
DNS server’s IP address. Specify only a single name server.
lg
7
The syslog server’s IP address. Specify the server that the HP Jetdirect print server sends syslog messages to.
hn
12
Host name. (This parameter does not accept a value.) When present in the file, 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 returned on an SNMP sysName request by a network application.
dn
15
Domain name. Specify the domain name for the HP Jetdirect print server (for example, support.hp.com). It does not include the host name, and is not the FQDN (such as printer1.support.hp.com).
ef
18
Extensions file. Specify the relative path name of the TFTP configuration file.
HP Jetdirect Print Servers note Bootptab file entries (IPv4) NOTE:

This is similar to the vendor-specific tag T144, described below.

na
44
NetBIOS-over-TCP/IP Name Server (NBNS) IP addresses. Specify a primary and secondary server in order of preference.
lease-time
51
DHCP IP address lease duration time. Specify the time in seconds.
tr
58
DHCP T1 timeout. Specify the DHCP lease renewal time in seconds.
tv
59
DHCP T2 timeout. Specify the DHCP lease rebind time in seconds.
T144
Relative path name of the TFTP configuration file. HP proprietary. Specify the path name using double quotes, for example “pathname”. Long path names are truncated. For file format information, see TFTP configuration file entries (IPv4).
HP Jetdirect Print Servers note Bootptab file entries (IPv4) NOTE:

Standard BOOTP option 18 (extensions file path) also allows a standard tag (ef) for specifying the relative path name of the TFTP configuration file.

T145
Idle timeout. HP proprietary. Specify the time, in seconds, that a print data connection can remain idle before being closed. The range is 1–3600 seconds.
T146
Buffer packing. HP proprietary. Set buffer packing for TCP/IP packets.
0 (default): Pack normal data buffers before sending to the printer.
1: Disable buffer packing. Data is sent to the printer when received.
T147
Write mode. HP proprietary. Set the TCP PSH flag for device-to-client data transfers.
0 (default): Disable.
1: Set the TCP PSH (all-push) in all data packets.
T148
IP gateway disable. HP proprietary. Control configuration of a Gateway IP address.
0 (default): Allow configuration of an IP address.
1: Prevent configuration.
T149
Interlock mode. HP proprietary. Require an acknowledgement (ACK) on all TCP packets before allowing the printer to close a port 9100 print connection. Specify a port number and option, as in the following example:
<Port Number> <Option>
<Port Number>: For supported HP Jetdirect print servers, the default port number is 1.
<Option>: Set to 0 (default) to disable interlock, or 1 to enable.
For example, setting this to “1 1” specifies port number 1 and enables interlock.
T150
TFTP server’s IP address. HP proprietary. Specify the IP address of the TFTP server where the TFTP configuration file is located.
T151
Network configuration. HP proprietary. Send either BOOTP-ONLY or DHCP-ONLY requests.
