Hi Charles and thanks for your help.
1. I just re-started the Ubuntu/Android system. This runs a root script
including "service nut-server start" followed by the same for
nut-client. I can check the status on both and they show as running. I
can see expected results running "upsc belkinusb".
2. When I check the results from "netstat -t -n" I am NOT finding
anything on 3493. Hmmm. I then tried "netstat -l" since there should be
a server socket listening on 3494, right? There is nothing of 3493. But
I do see an entry with local address = localhost:nut. When I "cat
/etc/services" I find nut listed on 3493.
3. So I run "netstat -l | grep nut" and I see the socket and I see an
entry for what looks like a stream listener tied to
/var/run/nut/blazer_usb-belkinusb.
4. I did not know of the -DD option on upsmon and likely would not have
thought of this anyhow. In the output I almost immediately see a
connection failure to belkinusb@localhost for the socket saying
permission denied. That doesn't look right. But not exactly what that
means or how to fix it.
This seems to be progress of a sort, at least for my understanding of
all this. Any further comments/tips?
Cheers

Thanks Roger for all your help here. I hope the 2 attachments come through. The
.sh is my doctored version of the script and the .report is its output. I
welcome any suggestions or ideas about what might be causing my problems with
monitoring to the Belkin UPS. Cheers
Hi David,
Nothing looks out of order in your configuration files. (They are fairly
similar to a configuration I am currently running on Ubuntu 18.04.)
You mentioned in the other thread that Ubuntu is running in a chroot in
Android. There is a chance that the Android kernel configuration is messing
with things here, and you may need to use strace to watch some of the system
calls.
In the mean time, what if you stop the nut-client service, and run upsmon in
debugging mode?
sudo /sbin/upsmon -DD
Also, what do you get from "netstat -tn | grep -w 3493"?
