4 floppyd - floppy daemon for remote access to floppy drive
17 This manpage has been automatically generated from mtools's texinfo
18 documentation, and may not be entirely accurate or complete. See the
19 end of this man page for details.
23 \&\fR\&\f(CWFloppyd\fR is used as a server to grant access to the floppy drive
24 to clients running on a remote machine, just as an X server grants
25 access to the display to remote clients. It has the following syntax:
27 \&\fR\&\f(CWfloppyd\fR [\fR\&\f(CW-d\fR] [\fR\&\f(CW-l\fR] [\fR\&\f(CW-s\fR \fIport\fR] [\fR\&\f(CW-r\fR
28 \&\fIuser\fR] [\fR\&\f(CW-b\fR \fIipaddr\fR] [\fR\&\f(CW-x\fR \fIdisplay\fR] \fIdevicenames\fR
30 \&\fR\&\f(CWfloppyd\fR is always associated with an X server. It runs on the
31 same machine as its X server, and listens on port 5703 and above.
35 \&\fR\&\f(CWfloppyd\fR authenticates remote clients using the \fR\&\f(CWXauthority\fR
36 protocol. Xhost authentication is not supported. Each floppyd is
37 associated with an X server. When a remote client attempts to connect
38 to floppyd, it sends floppyd the X authority record corresponding to
39 floppyd's X server. Floppyd in turn then tries to open up a connection
40 to the X server in order to verify the authenticity of the xauth record.
41 If the connection to the X server succeeds, the client is granted
43 \&\fR\&\f(CWDISPLAY\fR.
45 \&\fBCaution\fR: In order to make authentication work correctly, the
46 local host should \fBnot\fR be listed in the \fR\&\f(CWxhost\fR list of
48 Indeed, hosts listed in \fR\&\f(CWxhost\fR do not need a correct
49 \&\fR\&\f(CWXauthority\fR cookie to connect to the X server. As \fR\&\f(CWfloppyd\fR
50 runs on the same host as the X server, all its probe connection would
51 succeed even for clients who supplied a bad cookie. This means that
52 your floppy drive would be open to the world, i.e. a huge security hole.
53 If your X server does not allow you to remove \fR\&\f(CWlocalhost:0\fR and
54 \&\fR\&\f(CW:0\fR from the \fR\&\f(CWxhost\fR list, you can prevent floppyd from
55 probing those display names with the \fR\&\f(CW-l\fR option.
57 .SH Command\ line\ options
60 Daemon mode. Floppyd runs its own server loop. Do not supply this if
61 you start floppyd from \fR\&\f(CWinetd.conf\fR
63 \&\fR\&\f(CWs\ \ \fIport\fR\&\f(CW\fR\
64 Port number for daemon mode. Default is 5703 + \fIdisplaynumber\fR.
65 This flag implies daemon mode. For example, for display
66 \&\fR\&\f(CWhitchhiker:5\fR, the port would be 5708.
68 \&\fR\&\f(CWb\ \ \fIipaddr\fR\&\f(CW\fR\
69 Bind address (for multi homed hosts). This flag implies daemon mode
71 \&\fR\&\f(CWr\ \fIuser\fR\&\f(CW\fR\
72 Run the server under as the given user
74 \&\fR\&\f(CWx\ \fIdisplay\fR\&\f(CW\fR\
75 X display to use for authentication. By default, this is taken from the
76 \&\fR\&\f(CWDISPLAY\fR variable. If neither the \fR\&\f(CWx\fR attribute is present
77 nor \fR\&\f(CWDISPLAY\fR is set, floppyd uses \fR\&\f(CW:0.0\fR.
79 \&\fIdevicenames\fR is a list of device nodes to be opened. Default
80 is \fR\&\f(CW/dev/fd0\fR. Multiple devices are only supported on mtools
81 versions newer than 3.9.11.
83 .SH Connecting\ to\ floppyd
85 In order to use floppyd, add the flag \fR\&\f(CWremote\fR to the device
86 description in your \fR\&\f(CW\(if~/.mtoolsrc\(is\fR file. If the flag \fR\&\f(CWremote\fR
87 is given, the \fR\&\f(CWfile\fR parameter of the device description is taken
88 to be a remote address. It's format is the following:
89 \&\fIhostname\fR\fR\&\f(CW:\fR\fIdisplaynumber\fR[\fR\&\f(CW/\fR[\fIbaseport\fR][\fR\&\f(CW/\fR\fIdrive\fR]]. When
90 using this entry, mtools connects to port
91 \&\fIbaseport\fR+\fIdisplaynumber\fR at \fIhostname\fR. By default
92 \&\fIbaseport\fR is 5703. The drive parameter is to distinguish among
93 multiple drives associated with a single display (only mtools versions
94 more recent than 3.9.11)
98 The following starts a floppy daemon giving access to \fR\&\f(CW\(if/dev/fd0\(is\fR,
99 listening on the default port 5703, tied to the default X servers:
113 Each of the following starts a floppy daemon giving access to
114 \&\fR\&\f(CW\(if/dev/fd1\(is\fR, tied to the :1 local X servers, and listening on port
115 5704. We assume that the local host is named \fR\&\f(CWhitchhiker\fR.
122 floppyd -d -x :1 -p 5704 /dev/fd0
130 If you want to start floppyd by \fR\&\f(CWinetd\fR instead of running it as a
131 daemon, insert the following lines into \fR\&\f(CW\(if/etc/services\(is\fR:
137 floppyd-0 5703/tcp # floppy daemon for X server :0
138 floppyd-1 5704/tcp # floppy daemon for X server :1
146 And insert the following into \fR\&\f(CW\(if/etc/inetd.conf\(is\fR (assuming that you
147 have defined a user named floppy in your \fR\&\f(CW\(if/etc/passwd\(is\fR):
154 floppyd-0 stream tcp wait floppy /usr/sbin/floppyd floppyd /dev/fd0
155 floppyd-1 stream tcp wait floppy /usr/sbin/floppyd floppyd -x :1 /dev/fd0
163 Note that you need to supply the X display names for the second
164 floppyd. This is because the port is opened by inetd.conf, and hence
165 floppyd cannot know its number to interfere the display number.
167 On the client side, insert the following into your \fR\&\f(CW\(if~/.mtoolsrc\(is\fR
168 to define a drive letter accessing floppy drive in your X terminal:
173 drive x: file="$DISPLAY" remote
181 If your X terminal has more than one drive, you may access the
182 additional drives as follows:
187 drive y: file="$DISPLAY//1" remote
188 drive z: file="$DISPLAY//2" remote
198 .SH Viewing\ the\ texi\ doc
199 This manpage has been automatically generated from mtools's texinfo
200 documentation. However, this process is only approximative, and some
201 items, such as crossreferences, footnotes and indices are lost in this
202 translation process. Indeed, these items have no appropriate
203 representation in the manpage format. Moreover, not all information has
204 been translated into the manpage version. Thus I strongly advise you to
205 use the original texinfo doc. See the end of this manpage for
206 instructions how to view the texinfo doc.
209 To generate a printable copy from the texinfo doc, run the following
215 ./configure; make dvi; dvips mtools.dvi
224 To generate a html copy, run:
229 ./configure; make html
235 \&\fRA premade html can be found at
236 \&\fR\&\f(CW\(ifhttp://www.gnu.org/software/mtools/manual/mtools.html\(is\fR
239 To generate an info copy (browsable using emacs' info mode), run:
244 ./configure; make info
252 The texinfo doc looks most pretty when printed or as html. Indeed, in
253 the info version certain examples are difficult to read due to the
254 quoting conventions used in info.
