DHCP6S(8)                 BSD System Manager’s Manual                DHCP6S(8)

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 speci‐
             fied.

     -k ctlkeyfile
             Use ctlkeyfile to store the shared secret to authenticate the
             communication with dhcp6ctl.  The default file name used when
             unspecified is /usr/local/etc/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
     /usr/local/etc/dhcp6s.conf  is the default configuration file.
     /var/db/dhcp6s_duid         is the default file to store the server’s
                                 DUID.
     /usr/local/etc/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 config‐
     uration file.

BUGS
     dhcp6s is incomplete and violates DHCPv6 protocol spec, in several
     aspects.  To name a few:

     1.   it does not assign temporary IPv6 addresses (nor will).
