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.
