NAME¶
dhcp6s
—
DHCPv6 server
SYNOPSIS¶
dhcp6s |
[ -c
configfile ]
[-Ddf ]
[-k
ctlkeyfile ]
[-p
ctlport ]
[-P
pid-file ]
interface |
DESCRIPTION¶
dhcp6s
replies to DHCPv6 client as DHCPv6
server.
dhcp6s
can give the following
information to clients.
- IPv6 prefixes for the requesting site
- Non-temporary IPv6 addresses
- A list of the DNS server addresses
- DNS Domain Search List
- A list of the NTP server addresses
- A list of the SIP server addresses
- SIP Server domain name
- A list of the NIS server addresses
- NIS domain name
- A list of the NIS+ server addresses
- NIS+ domain name
- A list of the BCMCS server addresses
- BCMCS Server domain name
Command line options are as below:
-c
configfile
- Use configfile as the configuration
file.
-d
- Print debugging messages.
-D
- Even more debugging information is printed.
-f
- Foreground mode (useful when debugging). Although
dhcp6s
usually prints warning,
debugging, or error messages to syslog(8), it
prints the messages to standard error if this option is specified.
-k
ctlkeyfile
- Use ctlkeyfile to store the shared secret
to authenticate the communication with
dhcp6ctl
. The default file name used
when unspecified is
/etc/wide-dhcpv6/dhcp6sctlkey. The
default name is intentionally same as that for
dhcp6ctl
so that the server and the
control command can share the file when
dhcp6ctl
controls the server on the
same node, which should be the typical case.
-p
ctlport
- Use ctlport as the port number listening
on to communicate with
dhcp6ctl
.
-P
pid-file
- Use pid-file to dump the process ID of
dhcp6s
.
FILES¶
- /etc/wide-dhcpv6/dhcp6s.conf
- is the default configuration file.
- /var/lib/dhcpv6/dhcp6s_duid
- is the default file to store the server's DUID.
- /etc/wide-dhcpv6/dhcp6sctlkey
- is the default key file to communicate with the control command. See
dhcp6ctl(8) for the file format.
- /var/run/dhcp6s.pid
- is the default file that contains pid of the currently running
dhcp6s
.

HISTORY¶
The
dhcp6s
command first appeared in
WIDE/KAME IPv6 protocol stack kit.
The
-n
dnsserv command-line option was obsoleted by
introducing a configuration file.
BUGS¶
dhcp6s
is incomplete and violates DHCPv6
protocol spec, in several aspects. To name a few:
- it does not assign temporary IPv6 addresses (nor will).
