NAME

  jdbreg - Registers hosts in the DHCP dynamic databases.

SYNOPSIS

  /usr/sbin/jdbreg [-d]	[-e] [-f character] [-s] [-l  |	-n] [-o] [-w]
  filename...

OPTIONS

  -d  Deletes the records whose	keys are implied by the	input file(s).

  -f character
      Uses character as	the field separator.  The default is the pipe |	char-
      acter.

  -s  Display all currently registered hosts.

DESCRIPTION

  The jdbreg program registers (or removes) hosts for configuration by DHCP.
  When the registered_hosts_only policy	is in effect, the server configure
  only clients whose MAC addresses are so registered. When this	policy is not
  in effect, registering hosts has no effect.

  Each record to be loaded is terminated by a newline, and the fields within
  each record delimited	by default with	the pipe (|) character,	although this
  may be changed with the -f command line option.

  The fields within the	data file(s) to	be loaded are as follows:

    +  MAC address

    +  MAC address type

    +  MAC address length (octets)

RESTRICTIONS

  Because the database used by join does not support multiuser concurrently,
  applications that write to it, lock the entire database.  This means that
  you cannot use jdbreg	while joind is running.	The converse is	also true.

FILES

  /var/join/*.hsh

  /var/join/*.btr
