725 This setting allows you to specify a default value for which
726 codepage the server uses. If this field is left blank no

739 depends on IPX!=n || INET
740 help
741 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
742 used by Novell NetWare clients to talk to file servers. It is to
743 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
744 to mount NetWare file server volumes and to access them just like
745 any other Unix directory. For details, please read the file
746 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
747 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
748
749 You do not have to say Y here if you want your Linux box to act as a
750 file *server* for Novell NetWare clients.

753 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

755 To compile this as a module, choose M here: the module will be called
756 ncpfs. Say N unless you are connected to a Novell network.

763 help
764 Coda is an advanced network file system, similar to NFS in that it
765 enables you to mount file systems of a remote server and access them
766 with regular Unix commands as if they were sitting on your hard
767 disk. Coda has several advantages over NFS: support for
768 disconnected operation (e.g. for laptops), read/write server
769 replication, security model for authentication and encryption,
770 persistent client caches and write back caching.
771
772 If you say Y here, your Linux box will be able to act as a Coda
773 *client*. You will need user level code as well, both for the
774 client and server. Servers are currently user level, i.e. they need
775 no kernel support. Please read
776 <file:Documentation/filesystems/coda.txt> and check out the Coda
777 home page <http://www.coda.cs.cmu.edu/>.
778
779 To compile the coda client support as a module, choose M here: the
780 module will be called coda.
