NAME
      ndc - name daemon control program
 


SYNOPSIS
      ndc [ -c channel ]  [ -l localsock ]  [ -p pidfile ]  [ -d ]
      [ -q ]  [ -s ]  [ -t ]  [ command ]
 


DESCRIPTION
      System administrators use the ndc  utility  to  control  the
      operation  of  a  name  server.  If the system administrator
      fails to list a command, ndc will prompt for  one  until  it
      reads EOF.
 


OPTIONS
      The ndc command supports the following options:
 
      -c channel
            Specify the rendezvous point for the control  channel.
            The  default value for channel is /var/run/ndc, a UNIX
            domain socket that is also the server's  default  con-
            trol  channel.  If  the  desired  control channel is a
            TCP/IP socket, then the format for the  channel  argu-
            ment   is   ipaddr/port.   For  example,  a  value  of
            127.0.0.1/54 would be TCP port 54 on the local host.
 
      -d    Turn on debugging  mode.  This  option  is  mainly  of
            interest to developers.
 
      -l localsock
            Bind the client side  of  the  control  channel  to  a
            specific  address. Servers can be configured to reject
            connections that do not come from specific  addresses.
            If  the  desired  control  channel is a TCP/IP socket,
            then  the  format  for  the  localsock   argument   is
            ipaddr/port.
 
      -p pidfile
             Use  for  backwards  compatibility  with  older  name
            servers.  It  enables ndc to use UNIX signals for con-
            trol  communications.  Optional   with   modern   name
            servers,  this  capability  may  not  be  supported in
            future releases.The command set that is  available  is
            narrower  when  the signal interface is used. A likely
            value for the pidfile argument is /var/run/named.pid.
 
      -q     Suppress prompt and result text.
 
      -s     Suppress non-fatal error announcements.
 
      -t     Turn on protocol and system tracing. Use this  option
            in installation debugging.

 COMMANDS
      The following commands are built into the ndc  utility.  The
      full  set  of  commands  that  the  name  server supports is
      dynamic. Use the help command for information on the  avail-
      able commands .
 
      /help Show help information for built in commands.
 
      /exit Exit from ndc command interpreter.
 
      /trace
            Toggle protocol and system tracing on and off. See -t.
 
      /debug
            Toggle debugging mode on and off. See -d.
 
      /quiet
            Toggle prompt and result information on and  off.  See
            -q.
 
      /silent
            Toggle announcement of non-fatal errors  on  and  off.
            See -s.

NOTES
      When the ndc utility is running in pidfile  mode,  pass  any
      arguments  to  start  and  restart  commands to the new name
      server on the command line. If the ndc utility is running in
      channel  mode,  there  is  no start command, and the restart
      command just tells the name server to execvp(2) itself.
