 NAME
      nisinit - NIS+ client and server initialization utility

 SYNOPSIS
      nisinit -r

      nisinit -p Y|D|N parent_domain host...

      nisinit -c -H host | -B | -C coldstart

 DESCRIPTION
      nisinit initializes a machine to be a NIS+ client or an NIS+ root
      master server.  It may be easier to use nisclient(1M) or nisserver(1M)
      to accomplish this same task.

    Options
      -r   Initialize the machine to be a NIS+ root server.  This option
	   creates the file /var/nis/root.object and initializes it to
	   contain information about this machine.  It uses the sysinfo()
	   system call to retrieve the name of the default domain.

	   To initialize the machine as an NIS+ root server, it is advisable
	   to use the -r option of nisserver(1M), instead of using nisinit
	   -r.

      -p  Y | D | N parent_domain host ...
	   This option is used on a root server to initialize a
	   /var/nis/parent.object to make this domain a part of the
	   namespace above it.	Only root servers can have parent objects.
	   A parent object describes the namespace ``above'' the NIS+ root.
	   If this is an isolated domain, this option should not be used.
	   The argument to this option tells the command what type of name
	   server is serving the domain above the NIS+ domain. When clients
	   attempt to resolve a name that is outside of the NIS+ namespace,
	   this object is returned with the error NIS_FOREIGNNS indicating
	   that a name space boundary has been reached. It is up to the
	   client to continue the name resolution process.

	   The parameter parent_domain is the name of the parent domain in a
	   syntax that is native to that type of domain. The list of host
	   names that follow the domain parameter are the names of hosts
	   that serve the parent domain. If there is more than one server
	   for a parent domain, the first host specified should be the
	   master server for that domain.

	   Y	Specifies that the parent directory is a NIS version 2
		domain.

	   D	Specifies that the parent directory is a DNS domain.

	   N	Specifies that the parent directory is another NIS+ domain.
		This option is useful for connecting a pre-existing NIS+
		subtree into the global namespace.

	   Note that in the current implementation, the NIS+ clients do not
	   take advantage of the -p feature. Also, since the parent object
	   is currently not replicated on root replica servers, it is
	   recommended that this option not be used.

      -c   Initializes the machine to be a NIS+ client.	 There are three
	   initialization options available: initialize by coldstart,
	   initialize by hostname, and initialize by broadcast.	 The most
	   secure mechanism is to initialize from a trusted coldstart file.
	   The second option is to initialize using a hostname that you
	   specify as a trusted host.  The third method is to initialize by
	   broadcast and it is the least secure method.

	   -C coldstart
		Causes the file coldstart to be used as a prototype
		coldstart file when initializing a NIS+ client.	 This
		coldstart file can be copied from a machine that is already
		a client of the NIS+ namespace.	 For maximum security, an
		administrator can encrypt and encode (with uuencode(1)) the
		coldstart file and mail it to an administrator bringing up a
		new machine.  The new administrator would then decode (with
		uudecode()), decrypt, and then use this file with the
		nisinit command to initialize the machine as an NIS+ client.
		If the coldstart file is from another client in the same
		domain, the nisinit command may be safely skipped and the
		file copied into the /var/nis directory as
		/var/nis/NIS_COLD_START.

	   -H hostname
		Specifies that the host hostname should be contacted as a
		trusted NIS+ server.  The nisinit command will iterate over
		each transport in the NETPATH environment variable and
		attempt to contact rpcbind(1M) on that machine.	 This
		hostname must be reachable from the client without the name
		service running.  For IP networks this means that there must
		be an entry in /etc/hosts for this host when nisinit is
		invoked.

	   -B	Specifies that the nisinit command should use an IP
		broadcast to locate a NIS+ server on the local subnet.	Any
		machine that is running the NIS+ service may answer.  No
		guarantees are made that the server that answers is a server
		of the organization's namespace.  If this option is used, it
		is advisable to check with your system administrator that
		the server and domain served are valid. The binding
		information can be dumped to the standard output using the
		nisshowcache(1M) command.

	   Note that nisinit -c will just enable navigation of the NIS+ name
	   space from this client.  To make NIS+ your name service, modify
	   the file /etc/nsswitch.conf to reflect that.	 See
	   nsswitch.conf(4) for more details.

 RETURN VALUE
      nisinit returns 0 on success and 1 on failure.

 EXAMPLES
      This example initializes the machine as an NIS+ client using the host
      freddy as a trusted server.

	   nisinit -cH freddy

      This example sets up a client using a trusted coldstart file.

	   nisinit -cC /tmp/colddata

      This example sets up a client using an IP broadcast.

	   nisinit -cB

      This example sets up a root server.

	   nisinit -r

 EXTERNAL INFLUENCES
    Environment Variables
      NETPATH	     This environment variable may be set to the transports
		     to try when contacting the NIS+ server (see
		     netconfig(4)).  The client library will only attempt to
		     contact the server using connection oriented
		     transports.

 FILES
      /var/nis/NIS_COLD_START
			  This file contains a list of servers, their
			  transport addresses, and their Secure RPC public
			  keys that serve the machine's default domain.
      /var/nis/hostname/root.object
			  This file describes the root object of the NIS+
			  namespace. It is a standard XDR-encoded NIS+
			  directory object that can be modified by
			  authorized clients using the nis_modify()
			  interface.
      /var/nis/hostname/parent.object
			  This file describes the namespace that is
			  logically above the NIS+ namespace. The most
			  common type of parent object is a DNS object.
			  This object contains contact information for a
			  server of that domain.
