NAME
       dhcp6c - DHCPv6 client daemon


SYNOPSIS
       dhcp6c  [-dDf]  [-r  all | ] [-R ] [-c
	    ] [-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 informa-
       tion (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
       Delegation 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 
	      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 
	      Allows dhcp6c to release the addresses.  This  option  is	 used
	      only when releasing addresses explicitly.


       -R 
	      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.
