NAME    [Toc]    [Back]

       bootpgw - Internet BOOTP Protocol gateway

SYNOPSIS    [Toc]    [Back]

       /usr/opt/obsolete/usr/sbin/bootpgw [-d level] [-t timeout]
       [-h hopcount] [-w waittime] server [server...]

OPTIONS    [Toc]    [Back]

       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 specified time.  The default value is 0.

OPERANDS    [Toc]    [Back]

       Specifies the name or IP address  of  a  BOOTP  server  to
       which the bootpgw forwards BOOTP requests.

DESCRIPTION    [Toc]    [Back]

       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

       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    [Toc]    [Back]

       You  cannot  run bootpgw and bprelay on the same system at
       the same time.

FILES    [Toc]    [Back]

       Defines the sockets and protocols used for  Internet  services.
