Peter,
Thanks, that's excellent work. I'm very interested to see how it works on a thin client. This could completely solve our NFS-Swap issue.
Progress Report, nbd works, on the client, fine. The patch which is meantioned on the website for nbdswap to work is I think needed. And strangly this seams to be a default part of the debian kernel on my computers, but is not in the ltsp kernel I'm using, which means recompiling the ltsp client kernel with the patch.
The comment on enbd. There is no reason why you can't use enbd instead you only need to install the right module on the client harddisk -image.
nbd seams to have very limited error reporting which is why this job is more difficult than it should be.

nbd has very limited error reports would be nice if it was able to connect for it to output an error if it is not going to work !!!Jim.

I've been looking at using nbd for swapping, but i've just not had the time to do it.
I've been trying to get this working, I've a load of thin clients that crash and I'm out of ideas why, I've noticed that nfs keeps dropping off for no reason on our network, So I thought nbd might be more stable especally for swap. I've been trying to get it working between two servers first. But the notes on the internet seam slighly terriable.
mkswap /dev/nbd/0
works fine which most of the comments say it should not. however
swapon /dev/nbd/0
says "swapon: /dev/nbd/0: Invalid argument"
Any ideas?

In answer to my own question, when creating the file with dd the bs must be specified to be a good value. |bs=1048576 works quite nicely. I'm going to try with a thin client tomarrow at work, I'll report back with my success and maybe a howto once its working.

inital tests show nbd to work fine on the server, its a matter of scripting it to work on startup now, and create the right files.
