jdbdump(8)
NAME
  jdbdump - Dumps fields from the DHCP dynamic databases.

SYNOPSIS
  /usr/sbin/jdbdump [-a] [-f character] [-k key]
       [-s date] tag...

FLAGS
  -a  Dumps dates in a readable form.  The default is to dump all date-time
      fields as UCT (seconds since GMT 1/1/70 00:00).

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

  -k key
      This option requests that a specific record with the given key be
      dumped.  The key has three fields: the client's hardware type, hardware
      address, and IP address of its subnet.  These three components should
      be separated by whitespace and enclosed within quotes (otherwise the
      shell will create multiple words).

  -s date
      Dumps records timestamped since date.  The default is to dump all the
      records regardless of the date of last modification.

DESCRIPTION
  The jdbdump command reads the databases used by joind to store information
  on client IP address leases and dynamic names and prints selected fields.
  Each record 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.  Date fields are displayed in
  Universal Coordinated Time (UCT), seconds since 00:00 01/01/1970 GMT,
  unless the -a flag is given, which alters the format to a more readable
  form.

  The following fields are always dumped:

    ·  MAC address

    ·  MAC address type

    ·  MAC address length (octets)

    ·  IP address

    ·  Start of lease (UCT)

    ·  Lease expiration (UCT)

    ·  Time when lease may be extended (UCT)

    ·  Time when host last renewed or acquired this lease (UCT)

    ·  IP address of server "owning" the lease

    ·  Hostname (sans domain)

    ·  Domain name

  Following these fields are any fields given by the command line "tag"
  arguments. These tags identify DHCP configuration parameters.	 They may
  numeric, a two character symbol, or the parameter's long name.  Consult
  RFC1533 for the numerical values or see bootptab(4) for the symbolic or
  long names.
