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 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.
−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.
dhcp6c.conf
Contains DHCPv6 client configuration information.
dhcp6c_duid
Contains DHCPv6 client DUID.
client6_leasesXXXXXX
Contains DHCPv6 client assigned IPv6 addresses and prefixes.
Check /var/log/messages if there are errors.
