       dibbler-client - a portable DHCPv6 client


       dibbler-client  is  a  portable implementation of the DHCPv6 client. 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-client [ run | start | stop | status | install | uninstall ]


       run  - starts client in the console. Client can be closed using ctrl-c.

       start - starts client in daemon mode.

       stop - stops running clients.

       status - shows status of the client and server.

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

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


       Let’s start with simple configuration. We want receive one IPv6 address
       and  there  is  only  one  Ethernet  interface  present.  In  that case
       client.conf file might be completly empty. Dibbler client will  request
       for  one  IPv6  address  on  each  up,  running  and  multicast capable
       interface (except loopback).

       Now some real example. We want one IPv6 address and receive DNS servers
       and  domain  name.  We are also not interested in the details, so debug
       mode is disabled.

       log-mode short
       log-level 6
       iface eth0
         ia { }
          option dns-server
          option domain

       Next example: we want only NIS domain and NIS server information.  That
       information  should  be periodicaly renewed, so we use lifetime option.
       We don’t need any addresses so stateless mode is used.

       log-mode short
       iface eth0
         option nis-server
         option nis-domain
         option lifetime

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


       All files are created in the /var/lib/dibbler directory. Dibbler client
       reads  /var/lib/dibbler/client.conf  file.  During  operation,  Dibbler
       saves various file in  that  directory.  After  reception  of  the  DNS
       servers  or domain informations, they are added to the /etc/resolv.conf
       file. After shutdown, that  information  is  removed  from  that  file.
       Option  values  are  stored  in  the  option-* files. Log file is named


       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-server(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.
