Thanks...I tried echoing the output of 'whois' but that says root.

The thing is that rsync is being run - does it matter how?. I dug a bit
deeper though, and turned up the debug on sshd on the server, and diffed the output.
I see 'good' and 'bad' attempts are the same up to
"expecting SSH2_MGG_NEWKEYS received [preauth]"
but that then a login launched by NetworkManager says
"Connection closed by XXX.YYY.ZZZ.??? [preauth]"
while one from me logged in as root says:
"SSH2_MGG_NEWKEYS received [preauth]"
Does this give any clues?
