NAME    [Toc]    [Back]

       nd6hostd - Neighbor discovery and autoconfiguration daemon
       for IPv6 hosts

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/nd6hostd [-d] [-D] [-l logfile] [-u] [-n name]

OPTIONS    [Toc]    [Back]

       Enables additional  debugging  information,  such  as  bad
       packets  received,  to  be  logged.   The  nd6hostd daemon
       remains under control of the host that started it;  therefore,
  an  interrupt  from  the controlling host stops the
       nd6hostd process.  Same as the -d option, but does not run
       as  a  daemon.   Specifies  a log file into which nd6hostd
       writes information about its actions.   The  log  contains
       information  about any changes to the routing tables and a
       history of recent route change messages sent and  received
       that  are  related  to  changed  routes.   Enables dynamic
       updates to the Domain Name  System  (DNS)  database.  Only
       global  unicast  addresses are updated.  Specifies a fully
       qualified domain name to use for dynamic DNS updates.

DESCRIPTION    [Toc]    [Back]

       The nd6hostd daemon receives  and  processes  IPv6  Router
       Advertisement  (RA) packets of the Neighbor Discovery Protocol.
  This enables  a  system  to  autoconfigure  itself
       without manual intervention.

       The  daemon performs the following functions, based on the
       contents of IPv6 Router Advertisements it receives: Router
       discovery - Learns the IPv6 address of default routers and
       installs default routes in the kernel routing table.   Onlink
  prefix  discovery  -  Learns  IPv6  on-link prefixes
       (ranges of IPv6 addresses that are directly reachable on a
       given  link).  Stateless Address Configuration - Automatically
 creates and deletes interface addresses.  If the  -u
       option  is  specified, nd6hostd updates the global address
       information in the DNS automatically, using the name specified
  with  the -n option (or the host name if the the -n
       option is not specified).  Interface attribute  configuration
  -  Automatically configures datalink attributes such
       as hop limit, reachable time,  retransmit  time  and  link

   Signals    [Toc]    [Back]
       The  following signals have the specified effect when sent
       to the nd6hostd process using the  kill(1)  command:  Displays
   internal  routing  tables.   Terminates  nd6hostd.
       Before exiting, nd6hostd removes any system state that was
       autoconfigured,  including  default  routers, on-link prefixes,
  IPv6  addresses,  and  dynamically   updated   DNS


              Do not use SIGKILL to terminate nd6hostd.

RESTRICTIONS    [Toc]    [Back]

       Do  not  run  the nd6hostd and ip6rtrd daemons on the same
       host, as this may produce unpredictable results.

FILES    [Toc]    [Back]

       Specifies the command  path  Routes  through  distant  and
       external gateways Contains the network name database
