 451           To compile the SMB support as a module, choose M here:
 452           the module will be called smbfs.  Most people say N, however.
 453
 454 config SMB_NLS_DEFAULT
 455         bool "Use a default NLS"
 456         depends on SMB_FS
 457         help
 458           Enabling this will make smbfs use nls translations by default. You
 459           need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
 460           settings and you need to give the default nls for the SMB server as
 461           CONFIG_SMB_NLS_REMOTE.
 462
 463           The nls settings can be changed at mount time, if your smbmount
 464           supports that, using the codepage and iocharset parameters.
 465
 466           smbmount from samba 2.2.0 or later supports this.
 467
 468 config SMB_NLS_REMOTE
 469         string "Default Remote NLS Option"

 471         default "cp437"
 472         help
 473           This setting allows you to specify a default value for which
 474           codepage the server uses. If this field is left blank no
 475           translations will be done by default. The local codepage/charset
 476           default to CONFIG_NLS_DEFAULT.
 477
 478           The nls settings can be changed at mount time, if your smbmount
 479           supports that, using the codepage and iocharset parameters.
 480
 481           smbmount from samba 2.2.0 or later supports this.

 487         depends on IPX!=n || INET
 488         help
 489           NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
 490           used by Novell NetWare clients to talk to file servers.  It is to
 491           IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
 492           to mount NetWare file server volumes and to access them just like
 493           any other Unix directory.  For details, please read the file
 494           <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
 495           the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
 496
 497           You do not have to say Y here if you want your Linux box to act as a
 498           file *server* for Novell NetWare clients.

 501           Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
 502
 503           To compile this as a module, choose M here: the module will be called
 504           ncpfs.  Say N unless you are connected to a Novell network.

 510         depends on INET
 511         help
 512           Coda is an advanced network file system, similar to NFS in that it
 513           enables you to mount file systems of a remote server and access them
 514           with regular Unix commands as if they were sitting on your hard
 515           disk.  Coda has several advantages over NFS: support for
 516           disconnected operation (e.g. for laptops), read/write server
 517           replication, security model for authentication and encryption,
 518           persistent client caches and write back caching.
 519
 520           If you say Y here, your Linux box will be able to act as a Coda
 521           *client*.  You will need user level code as well, both for the
 522           client and server.  Servers are currently user level, i.e. they need
 523           no kernel support.  Please read
 524           <file:Documentation/filesystems/coda.txt> and check out the Coda
 525           home page <http://www.coda.cs.cmu.edu/>.
 526
 527           To compile the coda client support as a module, choose M here: the
 528           module will be called coda.

 535           If you say Y here, you will get an experimental Andrew File System
 536           driver. It currently only supports unsecured read-only AFS access.
