NAME

dhcpv6client_ui — DHCPv6 client interface for requesting configuration parameters from the DHCPv6 server

SYNOPSIS

/usr/bin/dhcpv6client_ui -m interface_name -[t|T] [-R]

/usr/bin/dhcpv6client_ui -m interface_name -[t|T] [-I] [-o config_options] [-s vendor_specific_options]

/usr/bin/dhcpv6client_ui -r list_of_addresses

/usr/bin/dhcpv6client_ui -v

DESCRIPTION

dhcpv6client_ui is the interface through which a user contacts the client daemon, dhcpv6clientd, to obtain IPv6 addresses and other configuration parameters from the server. The default configuration parameters are specified as command line options when the DHCPv6 client daemon is invoked.

When dhcpv6client_ui requests for IPv6 addresses or other configuration parameters, the client daemon obtains them from the server and stores in the /etc/dhcpv6client.data file.

dhcpv6client_ui is executed on the same machine on which the client daemon is configured. Ensure that the client daemon is up and running before dhcpv6client_ui is executed.

Options

dhcpv6client_ui supports the following options:

-m interface_name

Request the client daemon to obtain IPv6 addresses for the named interface, interface_name, from the DHCPv6 server daemon if the -I option is not specified.

-o config_options

Specify the other configuration parameters that the client daemon must request from the server daemon.

This option must be used in conjunction with the -m option.

The configuration parameters that the client can request are listed below:

dns_sa: Obtain one or more DNS server addresses
dns_dl: Obtain the DNS domain list
sip_sa: Obtain one or more SIP server addresses
sip_dl: Obtain the SIP domain list
nis_sa: Obtain one or more NIS server addresses
nis_dl: Obtain the NIS domain name
nisp_sa: Obtain one or more NIS+ server addresses
nisp_dl: Obtain the NIS+ domain name
all: Obtain all the above listed parameters
default: Obtain all the default parameters configured in the dhcpv6 client daemon

-s vendor_specific_option_list

Specify the vendor-specific options that the client daemon must request from the server daemon.

This option must be used in conjunction with the -m option.

-r IPv6_Address_list

Release the specified IPv6 addresses.

-t

Get the temporary addresses from the dhcpv6 client daemon.

-v

Print the version information of the client daemon.

-I

Request only the other configuration parameters. Do not request IPv6 addresses.

-R

Notify the client daemon to utilize the IPv6 addresses already obtained for an interface instead of requesting new IPv6 addresses from the server.

This option must be used in conjunction with the -m option.

-T

Get both temporary and non-temporary addresses from the client daemon.

When there is no -t or -T option specified dhcpv6client_ui obtains only non-temporary addresses.

RETURN VALUES

dhcpv6client_ui returns 0 on success and 1 on failure.

EXAMPLES

dhcpv6client_ui obtains IPv6 address for the lan0 interface:

      dhcpv6client_ui -m lan0 

dhcpv6client_ui obtains IPv6 address for the lan0 interface and additional configuration parameters:

      dhcpv6client_ui -m lan0 -o dns_sa dns_dl

dhcpv6client_ui obtains only the DNS parameters for the lan0 interface:

      dhcpv6client_ui -m lan0 -I -o dns_sa dns_dl
