floppyd(1)		    General Commands Manual		    floppyd(1)

Name
       floppyd	-  floppy daemon for remote access to floppy drive floppyd_in-
       stalltest - tests whether floppyd is installed and running

Note of	warning
       This manpage has	been automatically  generated  from  mtools's  texinfo
       documentation,  and  may	not be entirely	accurate or complete.  See the
       end of this man page for	details.

Description
       Floppyd is used as a server to grant access  to	the  floppy  drive  to
       clients	running	on a remote machine, just as an	X server grants	access
       to the display to remote	clients.  It has the following syntax:

       floppyd [-d] [-l] [-s port] [-r user] [-b ipaddr] [-x display]  device-
       names

       floppyd is always associated with an X server.  It runs on the same ma-
       chine as	its X server, and listens on port 5703 and above.

Authentication
       floppyd authenticates remote clients  using  the	 Xauthority  protocol.
       Xhost  authentication is	not supported. Each floppyd is associated with
       an X server.  When a remote client attempts to connect to  floppyd,  it
       sends  floppyd  the  X  authority  record  corresponding	to floppyd's X
       server.	Floppyd	in turn	then tries to open up a	connection  to	the  X
       server in order to verify the authenticity of the xauth record.	If the
       connection to the X server succeeds,  the  client  is  granted  access.
       DISPLAY.

       Caution:	In order to make authentication	work correctly,	the local host
       should not be listed in the xhost list of allowed hosts.
	Indeed,	hosts listed in	xhost do not need a correct Xauthority	cookie
       to  connect  to the X server. As	floppyd	runs on	the same host as the X
       server, all its probe connection	would succeed  even  for  clients  who
       supplied	a bad cookie.  This means that your floppy drive would be open
       to the world, i.e. a huge security hole.
	If your	X server does not allow	you to remove localhost:0 and :0  from
       the  xhost  list,  you  can  prevent floppyd from probing those display
       names with the -l option.

Command	line options
       d      Daemon mode. Floppyd runs	its own	server loop.   Do  not	supply
	      this if you start	floppyd	from inetd.conf

       s  port
	      Port  number  for	deamon mode.  Default is 5703 +	displaynumber.
	      This flag	implies	daemon mode.  For example, for display	hitch-
	      hiker:5, the port	would be 5708.

       b  ipaddr
	      Bind  address  (for  multihomed hosts). This flag	implies	daemon
	      mode

       r user
	      Run the server under as the given	user

       x display
	      X	display	to use for authentication. By default, this  is	 taken
	      from the DISPLAY variable. If neither the	x attribute is present
	      nor DISPLAY is set, floppyd uses :0.0.

       devicenames is a	list  of  device  nodes	 to  be	 opened.   Default  is
       /dev/fd0.  Multiple devices are only supported on mtools	versions newer
       than 3.9.11.

Connecting to floppyd
	In order to use	floppyd, add the flag remote to	the device description
       in  your	`~/.mtoolsrc' file.  If	the flag remote	is given, the file pa-
       rameter of the device description is taken  to  be  a  remote  address.
       It's    format	is   the   following:	hostname:displaynumber[/[base-
       port][/drive]]. When using this entry, mtools connects  to  port	 base-
       port+displaynumber  at hostname.	By default baseport is 5703. The drive
       parameter is to distinguish among multiple  drives  associated  with  a
       single display (only mtools versions more recent	than 3.9.11)

Examples:
	The following starts a floppy daemon giving access to `/dev/fd0', lis-
       tening on the default port 5703,	tied to	the default X servers:

	  floppyd -d /dev/fd0

	Each of	 the  following	 starts	 a  floppy  daemon  giving  access  to
       `/dev/fd1', tied	to the :1 local	X servers, and listening on port 5704.
       We assume that the local	host is	named hitchhiker.

	  floppyd -d /dev/fd0
	  floppyd -d -x	:1 -p 5704 /dev/fd0

	If you want to start floppyd by	inetd instead of running it as a  dae-
       mon, insert the following lines into `/etc/services':

	  # floppy daemon
	  floppyd-0    5703/tcp	   # floppy daemon for X server	:0
	  floppyd-1    5704/tcp	   # floppy daemon for X server	:1

	And  insert  the  following  into `/etc/inetd.conf' (assuming that you
       have defined a user named floppy	in your	`/etc/passwd'):

	  # floppy daemon
	  floppyd-0 stream  tcp	 wait  floppy  /usr/sbin/floppyd floppyd /dev/fd0
	  floppyd-1 stream  tcp	 wait  floppy  /usr/sbin/floppyd floppyd -x :1 /dev/fd0

	Note that you need to supply the X display names for the second	 flop-
       pyd.  This is because the port is opened	by inetd.conf, and hence flop-
       pyd cannot know its number to interfere the display number.

       On the client side, insert the following	into your `~/.mtoolsrc'	to de-
       fine a drive letter accessing floppy drive in your X terminal:

	  drive	x: file="$DISPLAY" remote

       If  your	 X  terminal has more than one drive, you may access the addi-
       tional drives as	follows:

	  drive	y: file="$DISPLAY//1" remote
	  drive	z: file="$DISPLAY//2" remote

Viewing	the texi doc
       This manpage has	been automatically  generated  from  mtools's  texinfo
       documentation.  However,	 this  process is only approximative, and some
       items, such as crossreferences, footnotes and indices are lost in  this
       translation process.  Indeed, these items have no appropriate represen-
       tation in the manpage format.  Moreover,	not all	information  has  been
       translated into the manpage version.  Thus I strongly advise you	to use
       the original texinfo doc.  See the end of this manpage for instructions
       how to view the texinfo doc.

       *      To  generate a printable copy from the texinfo doc, run the fol-
	      lowing commands:

		     ./configure; make dvi; dvips mtools.dvi

       *      To generate a html copy,	run:

		     ./configure; make html

	      A	 premade  html	can  be	 found	at   `http://www.gnu.org/soft-
	      ware/mtools/manual/mtools.html'

       *      To  generate  an	info  copy (browsable using emacs' info	mode),
	      run:

		     ./configure; make info

       The texinfo doc looks most pretty when printed or as html.  Indeed,  in
       the  info  version  certain  examples  are difficult to read due	to the
       quoting conventions used	in info.
