NAME

       dhcp6c - DHCPv6 client daemon



SYNOPSIS

       dhcp6c  [-dDf]  [-r  all  | <ipv6 addresses>] [-R <ipv6 addresses>] [-c
            <configuration file>] [-I] interface



DESCRIPTION

       dhcp6c is an implementation of the DHCPv6 client.

       Using DHCPv6 messages and DHCPv6 options, dhcp6c is used to request and
       configure  IPv6  addresses  and  host network configuration information
       (i.e. DNS) for a network interface from the DHCPv6 server. It can  also
       be  used as a requesting router to request and configure Prefix Delega-
       tion for a subnet.

       The   assigned   IPv6   addresses   and   prefixes   are    saved    as
       /var/lib/dhcpv6/client6.leasesXXXXXX;  this file is used to request the
       same addresses and prefixes from the DHCPv6 server. Each dhcp6c  client
       has  a  client DHCP Unique Identifier (DUID); the DUID file is saved as
       /var/lib/dhcpv6/dhcp6c_duid.   The  dhcp6c  client   configuration   is
       defined in /etc/dhcp6c.conf.



OPTIONS

       -c <configuration file>
              Specifies the configuration file for dhcp6c


       -d     Enables dhcp6c to print debug messages.


       -D     Enables dhcp6c to print verbose debug messages.


       -f     Enables dhcp6c to work as a foreground application.  This option
              is helpful for debugging.


       -I     Allows dhcp6c to request network information only.


       -r <all | ipv6 addresses>
              Allows dhcp6c to release the addresses.   This  option  is  used
              only when releasing addresses explicitly.


       -R <ipv6 addresses>
              Allows dhcp6c to request the specified addresses.



FILES

       dhcp6c.conf
              Contains DHCPv6 client configuration information.


       dhcp6c_duid
              Contains DHCPv6 client DUID.


       client6_leasesXXXXXX
              Contains DHCPv6 client assigned IPv6 addresses and prefixes.



ERRORS

       Check /var/log/messages if there are errors.
