	  Sun added support for registering RPC services at an IPv6

	  (RFC 1833).

	  This option enables support in the kernel RPC server for
	  registering kernel RPC services via version 4 of the rpcbind
	  protocol.  If you enable this option, you must run a portmapper
	  daemon that supports rpcbind protocol version 4.

	  Serving NFS over IPv6 from knfsd (the kernel's NFS server)
	  requires that you enable this option and use a portmapper that
	  supports rpcbind version 4.

config SMB_FS
	tristate "SMB file system support (OBSOLETE, please use CIFS)"

	select NLS
	help
	  SMB (Server Message Block) is the protocol Windows for Workgroups
	  (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
	  files and printers over local networks.  Saying Y here allows you to
	  mount their file systems (often called "shares" in this context) and
	  access them just like any other Unix directory.  Currently, this
	  works only if the Windows machines use TCP/IP as the underlying
	  transport protocol, and not NetBEUI.  For details, read
	  <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
	  available from <http://www.tldp.org/docs.html#howto>.

	  Note: if you just want your box to act as an SMB *server* and make
	  files and printing services available to Windows clients (which need
	  to have a TCP/IP stack), you don't need to say Y here; you can use
	  the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
	  for that.

	  General information about how to connect Linux, Windows machines and
	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

	  To compile the SMB support as a module, choose M here:
	  the module will be called smbfs.  Most people say N, however.

config SMB_NLS_DEFAULT
	bool "Use a default NLS"
	depends on SMB_FS
	help
	  Enabling this will make smbfs use nls translations by default. You
	  need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
	  settings and you need to give the default nls for the SMB server as
	  CONFIG_SMB_NLS_REMOTE.

	  The nls settings can be changed at mount time, if your smbmount
	  supports that, using the codepage and iocharset parameters.

	  smbmount from samba 2.2.0 or later supports this.

config SMB_NLS_REMOTE
	string "Default Remote NLS Option"
	depends on SMB_NLS_DEFAULT
	default "cp437"
	help
	  This setting allows you to specify a default value for which
	  codepage the server uses. If this field is left blank no
	  translations will be done by default. The local codepage/charset
	  default to CONFIG_NLS_DEFAULT.

	  The nls settings can be changed at mount time, if your smbmount

	  NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
	  used by Novell NetWare clients to talk to file servers.  It is to
	  IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
	  to mount NetWare file server volumes and to access them just like
	  any other Unix directory.  For details, please read the file
	  <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
	  the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

	  You do not have to say Y here if you want your Linux box to act as a
	  file *server* for Novell NetWare clients.

	  General information about how to connect Linux, Windows machines and
	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

	  To compile this as a module, choose M here: the module will be called

config CODA_FS
	tristate "Coda file system support (advanced network fs)"
	depends on INET
	help
	  Coda is an advanced network file system, similar to NFS in that it
	  enables you to mount file systems of a remote server and access them
	  with regular Unix commands as if they were sitting on your hard
	  disk.  Coda has several advantages over NFS: support for
	  disconnected operation (e.g. for laptops), read/write server
	  replication, security model for authentication and encryption,
	  persistent client caches and write back caching.

	  If you say Y here, your Linux box will be able to act as a Coda
	  *client*.  You will need user level code as well, both for the
	  client and server.  Servers are currently user level, i.e. they need
	  no kernel support.  Please read
	  <file:Documentation/filesystems/coda.txt> and check out the Coda
	  home page <http://www.coda.cs.cmu.edu/>.

	  To compile the coda client support as a module, choose M here: the
	  module will be called coda.

config AFS_FS

	  If you say Y here, you will get an experimental Andrew File System

	  If unsure, say N.
