NAME

     dhcp6s - DHCPv6 server

SYNOPSIS

     dhcp6s [-c configfile] [-Ddf] [-k ctlkeyfile] [-p ctlport] 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

     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 dhcp6sctl.  The default file name used when
             unspecified is /etc/dhcp6sctlkey.  The default name is
             intentionally same as that for dhcp6sctl so that the server and
             the control command can share the file when dhcp6sctl 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
             dhcp6sctl.

FILES

     /etc/dhcp6s.conf  is the default configuration file.
     /var/lib/dhcpv6/dhcp6s_duid
                       is the default file to store the server’s DUID.
     /etc/dhcp6sctlkey
                       is the default key file to communicate with the control
                       command.  See dhcp6sctl(8) for the file format.

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:

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

     2.   Some of useful option type values are still not officially assigned.
          The current implementation uses experimental values, which may cause
          interoperability problems with other implementations.
