          SCO, Xenix and Coherent are commercial Unix systems for Intel

          here would allow you to read from their floppies and hard disk
          partitions.

          If you have floppies or hard disk partitions like that, it is likely
          that they contain binaries from those other Unix systems; in order
          to run these binaries, you will want to install linux-abi which is
          a set of kernel modules that lets you run SCO, Xenix, Wyse,
          UnixWare, Dell Unix and System V programs under Linux.  It is
          available via FTP (user: ftp) from
          <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
          NOTE: that will work only for binaries from Intel-based systems;
          PDP ones will have to wait until somebody ports Linux to -11 ;-)

          If you only intend to mount files from some other Unix over the
          network using NFS, you don't need the System V file system support
          (but you need NFS file system support obviously).

          Note that this option is generally not needed for floppies, since a
          good portable way to transport files and directories between unixes
          (and even other operating systems) is given by the tar program ("man
          tar" or preferably "info tar").  Note also that this option has
          nothing whatsoever to do with the option "System V IPC". Read about
          the System V file system in
          <file:Documentation/filesystems/sysv-fs.txt>.
          Saying Y here will enlarge your kernel by about 27 KB.

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

          BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
          OpenBSD and NeXTstep) use a file system called UFS. Some System V
          Unixes can create and mount hard disk partitions and diskettes using
          this file system as well. Saying Y here will allow you to read from
          these partitions; if you also want to write to them, say Y to the
          experimental "UFS file system write support", below. Please read the
          file <file:Documentation/filesystems/ufs.txt> for more information.

          The recently released UFS2 variant (used in FreeBSD 5.x) is
          READ-ONLY supported.

          Note that this option is generally not needed for floppies, since a
          good portable way to transport files and directories between unixes
          (and even other operating systems) is given by the tar program ("man
          tar" or preferably "info tar").

          When accessing NeXTstep files, you may need to convert them from the
          NeXT character set to the Latin1 character set; use the program
          recode ("info recode") for this purpose.

          To compile the UFS file system support as a module, choose M here: the
          module will be called ufs.

          applications on NFS clients to manipulate POSIX Access Control
          Lists on files residing on NFS servers.  NFS servers enforce
          ACLs on local files whether this protocol is available or not.

          protocol extension and you want your NFS client to allow

          Choose Y here to enable Secure RPC using the SPKM3 public key
          GSS-API mechansim (RFC 2025).

          Secure RPC calls with SPKM3 require an auxiliary userspace
          daemon which may be found in the Linux nfs-utils package
          available from http://linux-nfs.org/.

          If unsure, say N.

        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
          supports that, using the codepage and iocharset parameters.

          smbmount from samba 2.2.0 or later supports this.

        help
          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.

config CODA_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.
