I can ssh from local to remote with no issue and it's configured so authentication does not use passwords, but uses the RSA ID.  This works perfectly.  "ssh remote" gets me logged in immediately.

I think you are mixing/confusing the 2 rsync methods.  One is the rsyncd
daemon.  To rsync to an rsyncd daemon, you use two colons after the
hostname, like this

rsync localfile tnet-web::threshNet-Public

This tranfers everything in the clear.  Last I checked, there was no
built-in method to transfer over ssh using the daemon.  You could set up
an SSL or SSH tunnel to do that.


The other method of using rsync is with a single colon, like this

rsync localfile tnet-web:threshNet-Public

This automatically uses ssh for transfer, but it requires a few things.

1)  your user must have an account on tnet-web
2)  threshNet-Public is a folder inside your user's home directory on
tnet-web
3)  it does not require an rsyncd.conf file, and doesn't look at it even
if you have one.


Hope that helps.
