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 BOOTREPLY. 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
BOOTREQUEST, the BOOTP server responds only if the server host can make the
file available.
