Hi All, Here are my scripts to provide transparent floppy acces to ltsp workstations. I wrote the scripts after an ideia from R. Stanford to provide floppy access to ltsp workstation using nbd. They are working stable after some testing. Users are able to mount and umount local floppy as any other device and my users using KDE do get a correct floppy icone independent of the workstation they are sitting at.
If anyone is interest, please try it and let me know if I forget something. Cicero

Transparent Floppy Access to LTSP Terminals

This document describes a way to provide transparent floppy access to
on a ltsp workstation. Other removable block devices should work as
well (CD, Zip Drive) but is not tested.
The main features are:
1) Users can mount and umount floppy as any other filesystem he
permission to;
2) Users using a graphical desktop like kde or gnome can have a floppy
icone that behaves as expected.
HOWTO
1) Install the ltsp_local_apps package. You doesn't need to configure NIS
if you doesn't need it for another reasons.
2) Include the line
floppy:x:509:100:/home:/bin/bash
in LTSROOT/etc/passwd and the line
users:x:100:
in LTSROOT/etc/group. Add a user with the same name to your ltsp server.
3) Copy nbd-server, nohup, nice, fuser to LTSROOT/bin and make
nbd-server setuid and owned by the floppy user.
copy rc.floppy to /LTSROOT/etc/rc.d/
copy mount.sh umount.sh to /bin in you ltsp server.
rename mount and umount to mount.system and umount.system
link mount.sh to mount and umount.sh to umount.
4) In the [Default] section of lts.conf include the line
RCFILE_10 = "rc.floppy"
4) For each workstation you want to provide floppy access, create a
network block device /dev/ltsp/wsname. For example, if you want to
provide access for workstations named ws01 and ws01
mkdir /dev/ltsp
mknod /dev/ltsp/ws01 b 43 1
mkdno /dev/ltsp/ws02 b 43 2
Create a directory to hold the mount points. For example
mkdir /ltspmedia
mkdir /ltspmedia/ws01
mkdir /ltspmedia/ws02
Then add
FLOPPY = Y
To the workstation section in lts.conf
5) Include the device you created in your ltspserver fstab. For
example add
/dev/ltsp/ws01 /ltspmedia/ws01 auto noauto,user 0 0
/dev/ltsp/ws02 /ltspmedia/ws02 auto noauto,user 0 0
6) Configure you ltspserver to network block devices
modprobe nbd
7) Allow you users to run fuser under the directory /dev/ltsp/ and run
rsh as the user floppy. Using sudo add the lines to the
/etc/sudoers file
Host_Alias TERMINALSERVER = 192.168.0.1
%users TERMINALSERVER = NOPASSWD: /bin/fuser /dev/ltsp/*
%users TERMINALSERVER = (floppy) NOPASSWD: /usr/bin/rsh * *
It's is done. Your users should be able to mount and umount
/dev/ltsp/ws0X
8) If you use KDE, your users will get a correct icone for floppy
any time they log in any workstation you if add the following lines
to their HOME/.profile file
