       dhcpy6d - MAC address aware DHCPv6 server


       dhcpy6d [-c file] [-u user] [-g group] [-r yes|no] [-d duid] [-G]


       dhcpy6d is an open source server for DHCPv6, the DHCP protocol for IPv6.

       Its  development  is driven by the need to be able to use the existing IPv4 infrastructure
       in coexistence with IPv6.  In a dualstack scenario, the existing DHCPv4 most probably uses
       MAC  addresses  of clients to identify them.  This is not intended by RFC 3315 for DHCPv6,
       but also not forbidden.  Dhcpy6d is able to do so in local network segments and  therefore
       offers a pragmatical method for parallel use of DHCPv4 and DHCPv6, because existing client
       management solutions could be used further.

       dhcpy6d comes with the following features:
        * identifies clients by MAC address, DUID or hostname
        * generates addresses randomly, by MAC address, by range or by given ID
        * filters clients by MAC, DUID or hostname
        * assigns multiple addresses per client
        * allows one to organize clients in different classes
        * stores leases in MySQL or SQLite database
        * client information can be retrieved from database or textfile
        * dynamically updates DNS (Bind)
        * supports rapid commit
        * listens on multiple interfaces


       Most configuration is done via the configuration file.

       -c, --config=configfile
              Set the configuration file to use. Default is /etc/dhcpy6d.conf.

       -u, --user=user
              Set the unprivileged user to be used.

       -g, --group=group
              Set the unprivileged group to be used.

       -r, --really-do-it=yes|no
              Really activate the DHCPv6 server. This is a precaution to prevent  larger  network

       -d, --duid=group
              Set the DUID for the server. This argument is used by /etc/init.d/dhcpy6d.

       -G, --generate-duid
              Generate  DUID  to be used in config file. This argument is used to generate a DUID
              for /etc/default/dhcpy6d. After generation dhcpy6d exits.
