* @defgroup rtems_ftpfs File Transfer Protocol File System

*
* You can mount the FTP file system with a call to mount() or
* mount_and_make_target_path() with the @ref RTEMS_FILESYSTEM_TYPE_FTPFS file
* system type.
*
* You have to add @ref CONFIGURE_FILESYSTEM_FTPFS to your application
* configuration.
*
* You can open files either read-only or write-only. A seek is not allowed.
* A close terminates the control and data connections.
*
* To open a file @c file.txt in the directory @c dir (relative to home
* directory of the server) on a server named @c host using the user name
* @c user and the password @c pw you must specify the following path:
* <tt>/FTP/user:pw@@host/dir/file.txt</tt>.
*
* If the server is the default server specified in BOOTP, it can be ommitted:
* <tt>/FTP/user:pw/dir/file.txt</tt>.
*
* The user name will be used for the password if it is ommitted:
* <tt>/FTP/user@@host/dir/file.txt</tt>.
*
* For the data transfer passive (= default) and active (= fallback) mode are
* supported.

* B. Schneier, Applied Cryptography: protocols, algorithms,

*
* Note that in that book's description of DES the lookups for the initial,
* pbox, and final permutations are inverted (this has been brought to the
* attention of the author). A list of errata for this book has been
* posted to the sci.crypt newsgroup by the author and is available for FTP.
*
* ARCHITECTURE ASSUMPTIONS:
* It is assumed that the 8-byte arrays passed by reference can be
* addressed as arrays of u_int32_t's (ie. the CPU is not picky about

* After start the net you can start this daemon.
* It uses the previously inited pseudo-terminales (pty.c)
* getting a new terminal with getpty(). This function
* gives a terminal name passing a opened socket like parameter.
*
* With register_telnetd() you add a new command in the shell to start
* this daemon interactively. (Login in /dev/console of course)
*
* Sorry but OOB is not still implemented. (This is the first version)
*
* Till Straumann <strauman@slac.stanford.edu>
* - made the 'shell' interface more generic, i.e. it is now
* possible to have 'telnetd' run an arbitrary 'shell'
* program.
