BOOTP Service

The bootpd Conﬁguration File

Tag Description

ba or ba=address Tells bootpd to broadcast the boot reply to the client. If you specify

no value for ba, bootpd sends the boot reply on the conﬁgured

broadcast address of each network interface on the server’s system.

If you specify an IP-address for its value, bootpd sends the boot

reply to a speciﬁc IP or broadcast address. Use the ba tag only for

diagnostic purposes, for example when debugging boot replies with

BOOTPQRY.

bf=filename Speciﬁes the ﬁlename, in Hierarchical File Structure (HFS) syntax,

of the bootﬁle that the client should download. The client’s boot

request, and the values of the hd and bf tags, determine the

contents of the bootﬁle ﬁeld in the boot reply packet.

bs=size or bs Speciﬁes the size of the bootﬁle in 512-octet blocks, expressed as a

decimal, octal, or hexadecimal integer. Or, if you omit the value,

bootpd will automatically calculate the bootﬁle size at each

request.

ds=ip address list Speciﬁes the IP address of one or more RFC1034 Domain Name

servers.

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.
