Troubleshooting bootpd
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:
1. Open the bootpd configuration file and look for the entry
describing the network device you want to test.
2. 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.
3. 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.
-iipaddr The Internet address of the BOOTP client 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.
-sserver The name of the BOOTP server to which the boot
request should be sent directly. When the BOOTP
server is known, the boot request is not broadcast.
-vvendor 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.
-fbootfile 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.
