DESCRIPTION
dhcpv6db2conf
provides a means of translating the DHCPv6 client database,
/etc/dhcpv6client.data,
into a set of standard configuration file variables. The client database
consists of a series of records. Each record represents a unique
lan interface and a list of attributes, which
correspond to that interface. The attributes are configuration
parameters like: host's IP address, NTP server address, address of the
DHCPv6 server, NIS domain name etc for that interface.
With
dhcpv6db2conf,
you can list the contents of the database to
the screen, create a set of configuration staging files, or execute direct
edits on existing configuration files using the values contained in the client
database.
Options
dhcpv6db2conf
allows you to specify a list of lan interfaces on the command
line (e.g.
lan0 lan1...)
whose data needs to be translated to a
readable format. If no lan interface is specified,
dhcpv6db2conf
will process the entries of all interfaces which are UP. The
attributes can be selected for processing by
specifying a combination of one or more filter flags on the command line. If
no filter flag is specified, all
the attributes for that lan interface will be processed.
The following options are supported:
- -a
Using the results of the specified filter, directly apply the variable
definitions to the existing configuration files (for example,
/etc/rc.config.d/netconf-ipv6).
- -c
Create a set of staging files using the results of the selected filter(s).
Each variable processed will be applied to its corresponding staging configuration file.
Specifically,
dhcpv6db2conf
will generate a copy of the existing
configuration file. For example,
/etc/rc.config.d/netconf-ipv6
will be copied to
/etc/rc.config.d/netconf-ipv6.dhcpv6.
Once this staging file has been created,
the variable that is being processed will be applied to this newly created
file.
- -d
Process the DNS variable set:
[domain, nameserver ].
- -i
Process the
INTERFACE
variable set:
[IPV6_SECONDARY_INTERFACE_NAME,
IPV6_ADDRESS,
IPV6_PREFIXLEN,
DHCPV6_ENABLE].
- -n
Process the NIS variable set:
[NIS_DOMAIN,
YPSET_ADDR].
- -p
Print results to the screen (stdout), this is the default action if neither
-c
nor
-a
are specified.
- -t
Process the
NTPDATE_SERVER
variable.
- lan_interfaces
lan interfaces such as
lan0, lan1, etc.
whose data needs to be translated to a readable format.
If not specified,
dhcpv6db2conf
will process
the entries of all interfaces which are UP.
Configuration Files and Variable Names
The following files and variables can be processed:
- /etc/rc.config.d/netconf-ipv6
IPV6_SECONDARY_INTERFACE_NAME
IPV6_ADDRESS
IPV6_PREFIXLEN
DHCPV6_ENABLE
- /etc/rc.config.d/namesvrs
- /etc/rc.config.d/netdaemons
- /etc/resolv.conf
EXAMPLES

variable set for

WARNINGS
The NIS and NTP parameters are not IPv6-compatible.
Hence do not use
dhcpv6db2conf
to update them.
