dhcp6c - DHCPv6 client daemon
dhcp6c [-dDf] [-r all | <ipv6 addresses>] [-R <ipv6 addresses>] [-c
<configuration file>] [-I] interface
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.
-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.
Contains DHCPv6 client configuration information.
Contains DHCPv6 client DUID.
Contains DHCPv6 client assigned IPv6 addresses and prefixes.
Check /var/log/messages if there are errors.
