.SH Description
|
|
.PP
|
|
\&\fR\&\f(CWFloppyd\fR 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:
|
|
.PP
|
|
\&\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
|
|
\&\fIuser\fR] [\fR\&\f(CW-b\fR \fIipaddr\fR] [\fR\&\f(CW-x\fR \fIdisplay\fR] \fIdevicenames\fR
|
|
.PP
|
|
\&\fR\&\f(CWfloppyd\fR is always associated with an X server. It runs on the
|
|
same machine as its X server, and listens on port 5703 and above.
|
|
.PP
|
|
.SH Authentication
|
|
.PP
|
|
\&\fR\&\f(CWfloppyd\fR authenticates remote clients using the \fR\&\f(CWXauthority\fR
|
|
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.
|
|
\&\fR\&\f(CWDISPLAY\fR.
|
|
.PP
|
|
\&\fBCaution\fR: In order to make authentication work correctly, the
|
|
local host should \fBnot\fR be listed in the \fR\&\f(CWxhost\fR list of
|
|
allowed hosts.
|
|
Indeed, hosts listed in \fR\&\f(CWxhost\fR do not need a correct
|
|
\&\fR\&\f(CWXauthority\fR cookie to connect to the X server. As \fR\&\f(CWfloppyd\fR
|
|
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 \fR\&\f(CWlocalhost:0\fR and
|
|
\&\fR\&\f(CW:0\fR from the \fR\&\f(CWxhost\fR list, you can prevent floppyd from
|
|
probing those display names with the \fR\&\f(CW-l\fR option.
|
|
.PP

\&\fR\&\f(CWd\fR\
|
|
Daemon mode. Floppyd runs its own server loop. Do not supply this if

you start floppyd from \fR\&\f(CWinetd.conf\fR
|
|
.TP
|
|
\&\fR\&\f(CWs\ \ \fIport\fR\&\f(CW\fR\
|
|
Port number for daemon mode. Default is 5703 + \fIdisplaynumber\fR.
|
|
This flag implies daemon mode. For example, for display
|
|
\&\fR\&\f(CWhitchhiker:5\fR, the port would be 5708.
|

.TP

\&\fR\&\f(CWb\ \ \fIipaddr\fR\&\f(CW\fR\

Bind address (for multi homed hosts). This flag implies daemon mode

\&\fR\&\f(CWx\ \fIdisplay\fR\&\f(CW\fR\
|
|
X display to use for authentication. By default, this is taken from the
|
|
\&\fR\&\f(CWDISPLAY\fR variable. If neither the \fR\&\f(CWx\fR attribute is present
|
|
nor \fR\&\f(CWDISPLAY\fR is set, floppyd uses \fR\&\f(CW:0.0\fR.
|
|
.PP
|
|
\&\fIdevicenames\fR is a list of device nodes to be opened. Default
|
|
is \fR\&\f(CW/dev/fd0\fR. Multiple devices are only supported on mtools
|
|
versions newer than 3.9.11.
|
|
.PP
|
|
.SH Connecting\ to\ floppyd
|
|
.PP
|
|
In order to use floppyd, add the flag \fR\&\f(CWremote\fR to the device
|
|
description in your \fR\&\f(CW\(if~/.mtoolsrc\(is\fR file. If the flag \fR\&\f(CWremote\fR
|
|
is given, the \fR\&\f(CWfile\fR parameter of the device description is taken
|
|
to be a remote address. It's format is the following:
|
|
\&\fIhostname\fR\fR\&\f(CW:\fR\fIdisplaynumber\fR[\fR\&\f(CW/\fR[\fIbaseport\fR][\fR\&\f(CW/\fR\fIdrive\fR]]. When
|
|
using this entry, mtools connects to port
|
|
\&\fIbaseport\fR+\fIdisplaynumber\fR at \fIhostname\fR. By default
|
|
\&\fIbaseport\fR 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)
|
|
.PP
|
|
.SH Examples:

The following starts a floppy daemon giving access to \fR\&\f(CW\(if/dev/fd0\(is\fR,

listening on the default port 5703, tied to the default X servers:

Note that you need to supply the X display names for the second

|
floppyd. This is because the port is opened by inetd.conf, and hence

|
floppyd cannot know its number to interfere the display number.
|
|
.PP
|

On the client side, insert the following into your \fR\&\f(CW\(if~/.mtoolsrc\(is\fR

to define a drive letter accessing floppy drive in your X terminal:
