[Discuss] rsync issue

[jdm at moylan.us (dan moylan)]

i have two home computers: aldeberan and alphacent, as well
as a remote website moylan.us, aka 50.87.218.82.  some four
years ago (almost) dan ritter gave me instructions for
setting up passwordless rsync amongst the lot.  it's worked
like a charm ever since, except now.  alphacent is a new
thinkpad T470 and it seems not to work there.  i've set up
.ssh the same on all three:

-rw-------. 1 moylan moylan  539 221101:1436 authorized_keys
-rw-------. 1 moylan moylan 2.4K 221031:1623 known_hosts
-rw-------. 1 moylan moylan 1.8K 221031:1615 rsync.key
-rw-r--r--. 1 moylan moylan  521 221101:1518 rsync.key.pub

where the files are all identical, except for known_hosts.

i have a little command file, which downloads foo
passwordless on aldeberon, but not alphacent -- gotta put a
password in there.

#! /bin/bash
# downsync
  hml=/home3/moylanus
  hmr=moylanus at 50.87.218.82
  opt="-rlptgozE --delete"
  rsync $opt $hmr:foo $hml

and though this works fine on aldeberon itself, it doesn't
work passwordless on an ssh aldeberon window on alphacent.

i haven't a clue as to what's going on.  any suggestions?
