       bprelay - BOOTP relay agent

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/bprelay  [-f]  [-d  n]  [-h hopcount] [-i interface,interface...]
 [-t minutes] [-w seconds] server...

OPTIONS    [Toc]    [Back]

       Foreground mode.  In this mode, bprelay does not run as  a
       daemon.   All  messages  are written to stdout and stderr,
       although warnings and errors are still sent to  syslog(3).
       Without  this option, bprelay listens on all interfaces on
       which the underlying protocol supports broadcasting.  With
       this  option,  bprelay  listens  only  to those interfaces
       specified.  Any non-existent or invalid interface name are
       ignored.  Sets debug level to the numeric value n.  Larger
       values  of  n   provides   more   debugging   information.
       Instructs  bprelay  to not forward packets if the value of
       the hops field  in  the  BOOTP  packet  exceeds  hopcount.
       Instructs  bprelay  to  terminate  if  minutes have passed
       without any packets being received.  This option  is  only
       honored  if  bprelay was started from inetd(8).  Instructs
       bprelay to not forward packets until the secs field in the
       BOOTP packet header exceeds this value.

DESCRIPTION    [Toc]    [Back]

       The  bprelay  daemon forwards DHCP or BOOTP packets to the
       specified list of servers (server).  Servers may be  identified
  either  by  their  IP addresses or by their names.
       The bprelay agent normally runs as a daemon  process,  and
       may  be  started either from the shell command line interface
 or by inetd(8).

       The purpose of bprelay is to provide the same  service  as
       that found in router hardware, but to run on UNIX workstations.
  The bprelay agent listens for  DHCP/BOOTP  packets
       on  each  of the interfaces specified in the command line,
       and relays each packet to the  servers  specified.   As  a
       rule,  bprelay  forwards  each  and  every packet to every
       server specified, but it omits servers whose IP address is
       found to be on the same IP network as the receiving interface
 since those servers will presumably hear the original
       broadcast.

RESTRICTIONS    [Toc]    [Back]

       Non-standard subnet masks for all networks administered by
       bprelay, must be available either through /etc/netmasks or
       NIS.
