  1090. SMB (Server Message Block) is the protocol Windows for Workgroups
  1091. (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
  1092. files and printers over local networks. Saying Y here allows you to
  1093. mount their file systems (often called "shares" in this context) and
  1094. access them just like any other Unix directory. Currently, this
  1095. works only if the Windows machines use TCP/IP as the underlying
  1096. transport protocol, and not NetBEUI. For details, read
  1097. <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
  1098. available from <http://www.tldp.org/docs.html#howto>.
  1099. Note: if you just want your box to act as an SMB *server* and make
  1100. files and printing services available to Windows clients (which need
  1101. to have a TCP/IP stack), you don't need to say Y here; you can use
  1102. the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
  1103. for that.
  1104. General information about how to connect Linux, Windows machines and
  1105. Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
  1106. To compile the SMB support as a module, choose M here:
  1107. the module will be called smbfs. Most people say N, however.

  1111. help
  1112. Enabling this will make smbfs use nls translations by default. You
  1113. need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
  1114. settings and you need to give the default nls for the SMB server as
  1115. CONFIG_SMB_NLS_REMOTE.
  1116. The nls settings can be changed at mount time, if your smbmount
  1117. supports that, using the codepage and iocharset parameters.
  1118. smbmount from samba 2.2.0 or later supports this.

  1124. This setting allows you to specify a default value for which
  1125. codepage the server uses. If this field is left blank no
  1126. translations will be done by default. The local codepage/charset
  1127. default to CONFIG_NLS_DEFAULT.

  1136. NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
  1137. used by Novell NetWare clients to talk to file servers. It is to
  1138. IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
  1139. to mount NetWare file server volumes and to access them just like
  1140. any other Unix directory. For details, please read the file
  1141. <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
  1142. the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

  1153. help
  1154. Coda is an advanced network file system, similar to NFS in that it
  1155. enables you to mount file systems of a remote server and access them
  1156. with regular Unix commands as if they were sitting on your hard
  1157. disk. Coda has several advantages over NFS: support for
  1158. disconnected operation (e.g. for laptops), read/write server
  1159. replication, security model for authentication and encryption,
  1160. persistent client caches and write back caching.
  1161. If you say Y here, your Linux box will be able to act as a Coda
  1162. *client*. You will need user level code as well, both for the
  1163. client and server. Servers are currently user level, i.e. they need
  1164. no kernel support. Please read
  1165. <file:Documentation/filesystems/coda.txt> and check out the Coda
  1166. home page <http://www.coda.cs.cmu.edu/>.
  1167. To compile the coda client support as a module, choose M here: the
  1168. module will be called coda.
