OK, I tried that and got a certain kind of result. An Nbd-Swap folder
gets created in /tmp, and it contains a file named with the IP address
of the terminal. It is a 500+ MB file occupying just 32KB on the hard
drive.
But it seems to be ignoring my nbdswapd.conf parameter of Size=128, so I
wonder if this is working.
Could your swap.conf file be part of an older approach?
I double-checked the Ubuntu NBD Swap documentation, and I seem to have
had it executed exactly before introducting swap.conf. I was following
https://help.ubuntu.com/community/UbuntuLTSP/EnableNBDSWAP, though that
explicitly references Ubuntu 8.04 to 10.04. I found no newer documentation.
The only doubt I had about my execution concerned the instruction:
"Create a /etc/ltsp/nbdswapd.conf file with the size of desired swapfile
for each client" and it offered the sample entry of SIZE=256.
So in my case I created nbdswapd.conf with a single line: SIZE=128.
But if nbdswapd.conf format mimics lts.conf, then when the instruction
says "size ... for each client," it may mean that nbdswapd.conf should
like more like:
[Default]
size=128
[Client 3 MAC Address]
size=256
[Client 12 MAC Address]
size=256
So I edited my file and tried:
[Default]
size=128
But it didn't seem to make any difference. No swap file appeared in \tmp.
Should the swap file get created even if the client does not have a
current need for swap space?

I'm putting a couple tweaks in place in my new Lubuntu LTSP test setup.
(E.g. I turned off SSH-encrypted sessions for better performance on
the terminal, and I was able to verify that this was in force.)
I also believe I have NBD Swap set up:
Edit LTS.CONF to add:
[Default]
nbd_swap=true
Then add the line:
nbdswapd: ALL: keepalive
to your /etc/hosts.allow file
Then create /etc/ltsp/nbdswapd.conf with just this content for a
128MB swap file:
Size=128
Swap files should show up as /tmp/tmp.* files, but despite loading up
a BUNCH of stuff on a 128MB terminal (including Chromium with *lots*
of tabs open), nothing appeared.
Is there another way to verify that NBD Swap is working?
When I set up a lubuntu ltsp server I needed to add the swap.conf file
as shown below.
Add the following swap.conf file to /etc/nbd-server/conf.d
===============================
[swap]
exportname = /tmp/nbd-swap/%s
prerun = nbdswapd %s
postrun = rm -f %s
================================
