-config SMB_FS
- tristate "SMB file system support (OBSOLETE, please use CIFS)"
- depends on INET
- 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
- supports that, using the codepage and iocharset parameters.
-
- smbmount from samba 2.2.0 or later supports this.
