dhcp6c(8) -- Linux man page
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 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 <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.
