|
.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

|
||
|
|
.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.

.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.

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)
