745 help
746 Sun added support for registering RPC services at an IPv6
747 address by creating two new versions of the rpcbind protocol
748 (RFC 1833).
749
750 This option enables support in the kernel RPC server for
751 registering kernel RPC services via version 4 of the rpcbind
752 protocol. If you enable this option, you must run a portmapper
753 daemon that supports rpcbind protocol version 4.
754
755 Serving NFS over IPv6 from knfsd (the kernel's NFS server)
756 requires that you enable this option and use a portmapper that
757 supports rpcbind version 4.
758
759 If unsure, say N to get traditional behavior (register kernel
760 RPC services using only rpcbind version 2). Distributions
761 using the legacy Linux portmapper daemon must say N here.

806 SMB (Server Message Block) is the protocol Windows for Workgroups
807 (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
808 files and printers over local networks. Saying Y here allows you to
809 mount their file systems (often called "shares" in this context) and
810 access them just like any other Unix directory. Currently, this
811 works only if the Windows machines use TCP/IP as the underlying
812 transport protocol, and not NetBEUI. For details, read
813 <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
814 available from <http://www.tldp.org/docs.html#howto>.
815
816 Note: if you just want your box to act as an SMB *server* and make
817 files and printing services available to Windows clients (which need
818 to have a TCP/IP stack), you don't need to say Y here; you can use
819 the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
820 for that.

837 The nls settings can be changed at mount time, if your smbmount

886 Coda is an advanced network file system, similar to NFS in that it
887 enables you to mount file systems of a remote server and access them
888 with regular Unix commands as if they were sitting on your hard
889 disk. Coda has several advantages over NFS: support for
890 disconnected operation (e.g. for laptops), read/write server
891 replication, security model for authentication and encryption,
892 persistent client caches and write back caching.
893
894 If you say Y here, your Linux box will be able to act as a Coda
895 *client*. You will need user level code as well, both for the
896 client and server. Servers are currently user level, i.e. they need
897 no kernel support. Please read
