.Os KAME
.Sh NAME
.Nm dhcp6ctl
.Nd DHCPv6 client and server control utility
.\"
.Sh SYNOPSIS
.Nm
.Op Fl C \(ba Fl S
.Op Fl k Ar keyfile
.Op Fl p Ar port
.Op Fl s Ar address
.Ic command
.\"
.Sh DESCRIPTION
.Nm
controls the operation of a DHCPv6 process,
which is either
.Nm dhcp6c
or
.Nm dhcp6s ,
a DHCPv6 client or a server.
By default,
.Nm
controls a client.
The type of the process can also be specified explicitly by the
.Fl C
or
.Fl S
options.
.Pp
.Nm
communicates with the DHCPv6 process over a TCP connection,
sending commands authenticated with digital signatures.
Currently,
the only supported authentication algorithm is
HMAC-MD5,
which uses a shared secret on each end of the connection.
.Pp
Command line options are as below:
.Bl -tag -width indent
.\"
.It Fl C
Control a DHCPv6 client.
This option is exclusive with the
.Fl S
option.
.It Fl S
Control a DHCPv6 server.
This option is exclusive with the
.Fl C
option.
.It Fl k Ar keyfile
Use
.Ar keyfile
to provide the shared secret to communicate with the process.
The default file name used when unspecified is
.Pa /etc/wide-dhcpv6/dhcp6cctlkey
with a client,
and
.Pa /etc/wide-dhcpv6/dhcp6sctlkey
with a server.
.It Fl p Ar port
Specify
.Ar port
as the listening port of the process.
The default port number used when unspecified is 5546 for a client,
and 5547 for a server.
.It Fl s Ar address
Specify
.Ar address
as the listening address of the process.
The default address used when unspecified is ::1.
.El
.\"
.Sh KEY FILE
Since the operation available with the
.Nm
command is powerful,
the communication between the command and
.Nm dhcp6c
or
.Nm dhcp6s
must be authenticated.
The supported algorithm for authentication is HMAC-MD5,
which requires a shared secret,
and the secret is stored in the key file.
The key file must consist of a single line, in which the secret value
is written in the form of BASE-64 encoding.
.\"
.Sh COMMANDS
Each
.Ic command
specifies a single control operation.
Supported commands are as follows:
.Pp
.Bl -tag -width Ds -compact
.It Xo
.Ic reload
.Xc
This command specifies the process to reload the configuration file.
Existing bindings, if any, are intact.
.It Xo
.Ic remove Ar arguments
.Xc
This command is only applicable to a server.
This specifies the server to remove a run-time object
specified by
.Ar arguments
from the server.
Currently, the only possible object is one particular IA_NA or IA_PD
binding, which is specified as
.Ql Ic binding IA Ic IA_NA Ar IAID Ar DUID
or
.Ql Ic binding IA Ic IA_PD Ar IAID Ar DUID
where
.Ar IAID
is a decimal number specifying the IAID of the IA,
and
.Ar DUID
is a DHCP Unique Identifier of the binding.
The format of
.Ar DUID
is the same as that specified in
.Xr dhcp6s.conf 5 .
.It Xo
.Ic start Ic interface Ar ifname
.Xc
This command is only applicable to a client.
It tells the client to release the current configuration information
(if any) on the interface
.Ar ifname
and restart the DHCPv6 configuration process on the interface.
.It Xo
.Ic stop Ic interface Ar ifname
.Xc
This command is only applicable to a client.
It tells the client to release the current configuration information
(if any) on the interface
.Ar ifname .
Any timer running for the interface will be stopped,
and no more DHCPv6 messages will be sent on the interface.
The configuration process can later be restarted by the
.Ic start
command.
.It Xo
.Ic stop
.Xc
This command stops the specified process.
If the process is a client, it will release all configuration
information (if any) and exits.
.El
.\"
.Sh FILES
.Bl -tag -width /etc/wide-dhcpv6/dhcp6cctlkey -compact
.It Pa /etc/wide-dhcpv6/dhcp6cctlkey
is the default key file to communicate with a client.
.It Pa /etc/wide-dhcpv6/dhcp6sctlkey
is the default key file to communicate with a server.

command first appeared in WIDE/KAME IPv6 protocol stack kit.
