       dibbler-server - a portable DHCPv6 server


       dibbler-server  is  a  portable implementation of the DHCPv6 server. It
       supports both stateful (i.e. IPv6 address granting) and stateless (i.e.
       options  granting)  autoconfiguration.  There  are  ports available for
       Linux 2.4/2.6 systems as well as MS  Windows  XP  and  2003.  They  are
       freely available under GNU GPL version 2 (or later) license.


       dibbler-server [ run | start | stop | status | install | uninstall ]


       run  - starts server in the console. Server can be closed using ctrl-c.

       start - starts server in daemon mode.

       stop - stops running server.

       status - shows status of the server.

       install - installs server as a service. This is not implemented yet.

       uninstall - uninstall server service. This is not implemented yet.


       Let’s assume simple case: server should provide clients located on  the
       eth1  link with IPv6 addresses from range 2000::100/120 and should have
       preference set to 7:

       iface eth0
         preference 7
           pool 2000::100-2000::1ff

       Here is exmaple of server configured to work in a stateless mode  (i.e.
       only  options,  not  addresses  are  served).  If client support option
       renewal, it should do so once in a 500 seconds:

       log-level 7
       log-mode short
       iface eth0 {
        option dns-server 2000::100,2000::101
        option domain,
        option ntp-server 2000::200,2000::201,2000::202
        option time-zone  CET
        option sip-server 2000::300,2000::302,2000::303,2000::304
        option sip-domain,
        option nis-server 2000::400,2000::401,2000::404,2000::405,2000::405
        option nis-domain
        option nis+-server 2000::501,2000::502
        option nis+-domain
        option lifetime 500

       More examples can be found in the User’s Guide.


       All files are created in the /var/lib/dibbler directory. Dibbler server
       reads  /var/lib/dibbler/server.conf  file.  During  operation,  Dibbler
       saves various file in that directory.  Log file is named client.log.


       This implementation aims at conformance to the following standards:

       RFC 3315 DHCP for IPv6

       RFC 3319 SIP options for DHCPv6

       RFC 3646 DNS server options for DHCPv6

       RFC 3736 Stateless DHCPv6

       RFC 3898 NIS options for DHCPv6

       Also options specified in following drafts are implemented:

       draft-ietf-dhc-dhcpv6-opt-timeconfig-03.txt NTP and timezone options.

       draft-ietf-dhc-dhcpv6-opt-lifetime-00.txt Option renewal.

       Dibbler was developed as master thesis on the Technical  University  of
       Gdansk by Tomasz Mrugalski and Marek Senderski. Currently Marek has not
       enough free  time,  so  this  project  is  being  developed  by  Tomasz
       Mrugalski.   Authors   can   be   reached  at  and


       There is dibbler-client(8) manual page. You are also advised to take  a
       look  at project website located at  As far
       as  authors  know,  this  is   the   only   Windows   DHCPv6   stateful
       implementation  available. It is also one of two freely available under
       Linux.   The   other   Linux    implementation    is    available    at,  but it is rather outdated and seems not
       being actively developed.
