bootpgw(8)bootpgw(8)NAMEbootpgw - Internet BOOTP Protocol gateway
SYNOPSIS
/usr/opt/obsolete/usr/sbin/bootpgw [-d level] [-t timeout] [-h hop‐
count] [-w waittime] server [server...]
OPTIONS
Sets the debug-level variable that controls the number of debugging
messages generated. For example, -d 4 sets the debugging level to 4.
Sets the maximum hop count a BOOTP request can contain for this bootpgw
daemon to forward the packet. The default is 4. Specifies the timeout
value (in minutes) that the bootpgw process waits for a BOOTP packet
before exiting. If no packets are received for timeout minutes, the
program exits. A timeout value of zero means run forever. When the
bootpgw daemon is not started using the inetd daemon, this option is
forced to 0. Specifies the minimum wait time in seconds. Requests are
forwarded only if the client has been waiting for at least the speci‐
fied time. The default value is 0.
OPERANDS
Specifies the name or IP address of a BOOTP server to which the bootpgw
forwards BOOTP requests.
DESCRIPTION
The bootpgw daemon implements a simple BOOTP gateway that can be used
to forward requests and responses between clients and BOOTP servers
(for example, bootpd) on different subnets. In order to use the bootpgw
daemon, you must install the Obsolete Commands and Utilities subset
(OSFOBSOLETExxx).
The bootpgw can be started by the /usr/sbin/inetd daemon by specifying
the following line in the /etc/inetd.conf file: bootps dgram udp wait
root /usr/sbin/bootpgw bootpgw server
Note that server specifies the name or IP address of a bootp server to
which the bootpgw forwards bootp requests.
You may not have the bootpd daemon and the bootpgw daemon running on
the same system because they listen on the same bootps port.
When the bootpgw daemon is started, it determines the address of a
BOOTP server whose name is provided as a command line parameter. When
the bootpgw daemon receives a BOOTREQUEST packet, it sets the gateway
address and hop count fields in the packet and forwards it to the BOOTP
server at the address determined earlier.
Then the bootpgw daemon looks in the /etc/services file to find the
port numbers it should use. The following two entries are extracted:
The bootp server listening port. The destination port used to reply to
clients. If the port numbers cannot be determined this way, they are
assumed to be 67 for the server and 68 for the client.
RESTRICTIONS
You cannot run bootpgw and bprelay on the same system at the same time.
FILES
