The other options are rsyncd and rsh.

rsyncd means running another daemon on the server which is visible to the net (or at least 
the machines you want to be able to access it).  This is both a security risk (another 
possible attack vector) and unnecessary load on the server *grin*

rsh transmits usernames/passwords in clear text.


You can do a "ps -ef" on each end, and check to make sure that the two ends have ssh 
processes linked to the rsync ones.  On the server you should see an sshd running as you 
(IIRC) that has rsync as a child process.

On the client you should see an ssh process as a child of the rsync.  You can also check 
open ports between the two servers to make sure that the connection is on port 22.
