Configuring and Managing MPE/iX Internet Services (MPE/iX 6.5)

BOOTP Service
The bootpd Configuration File
gw=ip address list Specifies the IP address of one or more gateways for the client’s
subnet. If you prefer one of multiple gateways, list it first.
ha=hardware-address Specifies the hardware address of the client in hexadecimal. You may
include periods and/or a leading 0x for readability. The ha tag must
be preceded by the ht tag either explicitly or implicitly; see tc below.
hd=home-directory Specifies an HFS directory name to which the bootfile is appended
(see bf tag above). The default value is (/).
hn Directs bootpd to send the client’s hostname in the boot reply. The
BOOTP daemon attempts to send the entire hostname as it is specified
in the configuration file. If this cannot fit into the reply packet, it
attempts to shorten the name to just the host field (up to the first
period, if present) and send that. In no case will bootpd send an
arbitrarily truncated hostname. If nothing reasonable can fit, it sends
nothing.
ht=hardware-type Specifies the hardware type code. The hardware-type can be an
unsigned decimal, octal, or hexadecimal integer corresponding to one
of the ARP Hardware Type codes specified in RFA1010. The HP 3000
implementation will support ether for ethernet networks and
ieee802 for IEEE 802.3 networks.
ip=ip address Specifies the IP address of the BOOTP client.
sm=subnet-mask Specifies the client’s subnet mask as a single IP address.
T
nnn
=generic-data A generic tag where
nnn
is an RFC1048 vendor field tag number. This
allows bootpd to immediately take advantage of future extensions to
RFC1048. The generic-data data can be represented as either a
stream of hexadecimal numbers or as a quoted string of ASCII
characters. The length of the generic data is automatically
determined and inserted into the proper fields of the RFC1048-style
boot reply.
tc=template-host Indicates a table continuation. Often many host entries share
common values for certain tags (such as domain servers) and, rather
than repeatedly specifying these tags, a full specification can be listed
for one host entry and shared by others.
The template-host is a dummy host (configuration file entry) for a
host that does not actually exist and never sends boot requests.
Information explicitly specified for a host always overrides
information implied by a tc tag symbol, regardless of its location
within the entry. The value of template-host can be the hostname or
IP address of any host entry previously listed in the configuration file.
If it is necessary to delete a specific tag after it has been inferred via
tc, enter tag@. For example, to undo an RFC1034 domain name
server specification, use :ds@: at an appropriate place in the
configuration entry. After canceling the tag this way, you may set it
again.
