nas doesn't recognise login as authorised user
Turns out this was the issue - problem solved.For some reason the
interactive successful use of ssh must have used my non-root users key
even when run by (su) root in a graphical terminal. I needed to send a
root public key to the NAS to get it to accept the connection when run
from the daemon. /root/.ssh/authorized_keys in the NAS (running some
version of Linux) only had the normal user public key.
Thanks to all for the replies.
