839 If you only intend to mount files from some other Unix over the
840 network using NFS, you don't need the System V file system support
841 (but you need NFS file system support obviously).
842
843 Note that this option is generally not needed for floppies, since a
844 good portable way to transport files and directories between unixes
845 (and even other operating systems) is given by the tar program ("man
846 tar" or preferably "info tar"). Note also that this option has
847 nothing whatsoever to do with the option "System V IPC". Read about
848 the System V file system in
849 <file:Documentation/filesystems/sysv-fs.txt>.
850 Saying Y here will enlarge your kernel by about 27 KB.

852 To compile this as a module, choose M here: the module will be called
853 sysv.

1193 SMB (Server Message Block) is the protocol Windows for Workgroups
1194 (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
1195 files and printers over local networks. Saying Y here allows you to
1196 mount their file systems (often called "shares" in this context) and
1197 access them just like any other Unix directory. Currently, this
1198 works only if the Windows machines use TCP/IP as the underlying
1199 transport protocol, and not NetBEUI. For details, read
1200 <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
1201 available from <http://www.tldp.org/docs.html#howto>.
1202
1203 Note: if you just want your box to act as an SMB *server* and make
1204 files and printing services available to Windows clients (which need
1205 to have a TCP/IP stack), you don't need to say Y here; you can use
1206 the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
1207 for that.

1219 Enabling this will make smbfs use nls translations by default. You
1220 need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
1221 settings and you need to give the default nls for the SMB server as
1222 CONFIG_SMB_NLS_REMOTE.
1223
1224 The nls settings can be changed at mount time, if your smbmount
1225 supports that, using the codepage and iocharset parameters.

1250 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
1251 used by Novell NetWare clients to talk to file servers. It is to
1252 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
1253 to mount NetWare file server volumes and to access them just like
1254 any other Unix directory. For details, please read the file
1255 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
1256 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

1272 help
1273 Coda is an advanced network file system, similar to NFS in that it
1274 enables you to mount file systems of a remote server and access them
1275 with regular Unix commands as if they were sitting on your hard
1276 disk. Coda has several advantages over NFS: support for
1277 disconnected operation (e.g. for laptops), read/write server
1278 replication, security model for authentication and encryption,
1279 persistent client caches and write back caching.
1280
1281 If you say Y here, your Linux box will be able to act as a Coda
1282 *client*. You will need user level code as well, both for the
1283 client and server. Servers are currently user level, i.e. they need
1284 no kernel support. Please read
1285 <file:Documentation/filesystems/coda.txt> and check out the Coda
1286 home page <http://www.coda.cs.cmu.edu/>.
