The BOOTPQRY program is a diagnostic tool used to check the
configuration of bootpd. It uses the supplied parameters to construct
a boot request to send to a BOOTP server. It prints the contents of
the boot reply, including the client's Internet address, the name of a boot
file, and the name and address of the server that sent the reply.
BOOTPQRY formats and prints RFC1048 or CMU-style vendor information
included in the reply.
The boot request packet is broadcast on the BOOTP server port.
Responding servers return a bootreply packet on the BOOTP client port.
BOOTPQRY 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 boot request are those of the host on which
BOOTPQRY is run.
To use the BOOTPQRY program to troubleshoot bootpd, do the
following:
- Open the bootpd configuration file and look for the entry
describing the network device you want to test.
- When you find the entry, add the ba tag to it. This will force
bootpd to broadcast the reply so that BOOTPQRY can
display it.
- Run the BOOTPQRY program by entering the BOOTPQRY
command followed by the hardware address of the network you are testing,
expressed in hexadecimal notation. For example, at the CI prompt you
would enter:
:BOOTPQRY.NET.SYS 08000902CA00
Or, from the POSIX shell, you would enter:
$/etc/bootpquery 08000902CA00
Diagnostic Options
The following options provide the information for the boot request:
- Option
- Purpose
- haddr
- The hardware address of the BOOTP client to use in the boot
request. A BOOTP server responds if it has configuration
information for a host with this link level address.
- htype
- The type of address specified as haddr, which may be
ether or ieee802. The default address type is
ether.
- -i<ipaddr>
- The Internet address of the BOOTP client <ipaddr>
to use in the boot request. If the BOOTP client doesn't know
its IP address, the BOOTP server supplies it in the bootreply.
Otherwise, the server returns the bootreply directly to
ipaddr.
- -s<server>
- The name of the BOOTP server <server> to which
the boot request should be sent directly. When the BOOTP server
is known, the boot request is not broadcast.
- -v<vendor>
- Request vendor information for <vendor>. The 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<bootfile>
- Specify a boot file needed by the BOOTP client. If a boot file
is specified in the boot request, the BOOTP server responds
only if the server host can make the file available via
TFTP.
