  751. This setting allows you to specify a default value for which
  752. codepage the server uses. If this field is left blank no
  753. translations will be done by default. The local codepage/charset
  754. default to CONFIG_NLS_DEFAULT.
  755. The nls settings can be changed at mount time, if your smbmount
  756. supports that, using the codepage and iocharset parameters.
  757. smbmount from samba 2.2.0 or later supports this.

  763. NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
  764. used by Novell NetWare clients to talk to file servers. It is to
  765. IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
  766. to mount NetWare file server volumes and to access them just like
  767. any other Unix directory. For details, please read the file
  768. <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
  769. the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
  770. You do not have to say Y here if you want your Linux box to act as a
  771. file *server* for Novell NetWare clients.
  772. General information about how to connect Linux, Windows machines and
  773. Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
  774. To compile this as a module, choose M here: the module will be called
  775. ncpfs. Say N unless you are connected to a Novell network.

  780. help
  781. Coda is an advanced network file system, similar to NFS in that it
  782. enables you to mount file systems of a remote server and access them
  783. with regular Unix commands as if they were sitting on your hard
  784. disk. Coda has several advantages over NFS: support for
  785. disconnected operation (e.g. for laptops), read/write server
  786. replication, security model for authentication and encryption,
  787. persistent client caches and write back caching.
  788. If you say Y here, your Linux box will be able to act as a Coda
  789. *client*. You will need user level code as well, both for the
  790. client and server. Servers are currently user level, i.e. they need
  791. no kernel support. Please read
  792. <file:Documentation/filesystems/coda.txt> and check out the Coda
  793. home page <http://www.coda.cs.cmu.edu/>.
  794. To compile the coda client support as a module, choose M here: the
  795. module will be called coda.
