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:

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