NAME
bootpquery - send BOOTREQUEST to BOOTP server
SYNOPSIS
/usr/sbin/bootpquery
haddr [ htype ][options ]
DESCRIPTION
bootpquery is a diagnostic function used to check the configuration of the Internet Bootstrap Protocol
(BOOTP) server, bootpd(1M). This function can only be run by the superuser, since it uses reserved ports.
bootpquery constructs a boot request with the supplied parameters to send to the BOOTP server, and
prints the contents of the BOOTP server reply (as shown in EXAMPLES, below). Note that
bootpquery
formats and prints RFC-1048 or CMU-style vendor information included in the BOOTREPLY.
The BOOTREQUEST packet is broadcast on the BOOTP server port,
bootps. If a BOOTP server is
configured to respond to the request, it returns a BOOTREPLY packet on the BOOTP client port,
bootpc.
bootpquery can only display BOOTREPLY packets when the BOOTP server broadcasts the reply on the
client port or when the hardware address and IP address supplied in the BOOTREQUEST are those of the
host on which bootpquery is run.
The following options provide the information for the BOOTREQUEST:
haddr Hardware address of the BOOTP client; used in the BOOTREQUEST. A BOOTP server
responds if it has configuration information for a host with this link-level address.
htype Type of address specified as haddr; may be ether or
ieee802. The default address type
is
ether.
-iipaddr
Specify the internet address of the BOOTP client to be used in the BOOTREQUEST. If the
BOOTP client does not know its IP address, the BOOTP server supplies it in the BOOTRE-
PLY. Otherwise, the server returns the BOOTREPLY directly to ipaddr.
-sserver
Specify the name of the BOOTP server to receive BOOTREQUEST. When the BOOTP server
is known, the BOOTREQUEST is not broadcast.
-vvendor
Specify a vendor name to include vendor information in the BOOTREPLAY. vendor can be
specified as
rfc1048 or cmu. For any other vendor specification, the first four characters
of the parameter are used as the vendor magic cookie.
-f Specify that bootpd should broadcast the reply back. This option is only valid for bootpd
on the HPUX 10.0 (or later) release(s).
-bbootfile
Specify a boot file needed by the BOOTP client. If a boot file is specified in the BOOTRE-
QUEST, the BOOTP server responds only if the server host can make the file available.
