Scott, works perfectly and definitely gets the job done.  Only problem is it doesn't
properly quit these processes:

7196 	nobody 	0.0 % 	21:07 	/bin/sh /usr/sbin/nbdswapd
7213 	nobody 	0.0 % 	21:07 	/bin/nbd-server 0 /tmp/fileEEyGZb

Is this a problem and should they be manually killed?  I've noticed if clients aren't
shut down with the shutdown button at the login screen these processes are left over. 
If it isn't a big deal I'll just let them clean themselves up when the server reboots.

I have made scripts and put them on my desktop in a folder called "Client Shutdown".  I
have a script for each of my labs.  Now I can just double click a file and the whole lab
shuts down......awesome!

Thanks,
Jim

Hello Fred,
I'm not sure if this is possible, but I have been experimenting:
1. If we unplug the network cable for a short time (less than 1 minute), the 
session resumes. If longer, it fails to resume (hang).
2. If we unplug the cable and restart (hard reboot) the client, it doesn't 
resume.
3. If we turn off the server while keep the client running, next time the 
server up, the client automatically resumes (logon screen), no need to 
restart the client.

Cheers,
--

check your /etc/hosts.allow.  You should have:

nbdswapd: ALL: keepalive

in there.  If you do, they'll exit quietly and clean up after themselves
after 2 hours, all by their lonesomes.

If not, add it :)

This is a great idea. One thing I would like to have for my network is a 
persistent "bittorrent" user, who would have only one program open, but 
have it going all the time, persistently. Any user with the password 
would be able to log in, check the status of torrents, add or remove 
torrents, and then log out and have the server be swarming day and night 
until their downloads were finished.

Is this possible?

inter-user messaging

What is the best way to implement an inter-user message system on a LTSP
server?  It's currently running Fedora Core 6 with Gnome desktops.

The objective is to allow pop-up messages between users, sort of a "private MSN
chat"  thing.

Frank,

I use jabber (ejabberd) and gaim

makes a great Instant messaging system.

Now that looks like the real McCoy!

Thanks, Jim.  Now I have a project for this weekend....

Re: Keeping sessions open?

Hello David...

Vnc is exactly what you need. It'll create a persistant session, bound
to a single user. And when you're done checking your torrents, just
close your vnc-client.

Re: Keeping sessions open?

Hi all,
We use nomachine NX client to make persistent sessions (i.e. whole
desktop is running in NX) but freeNX would work as well.
This is also much faster than VNC.
Note that plain X11 protocol can not be made persistent, this can only
be achieved via NX/VNC/Citrix ICA
