sender: 2.5.7
<br>receiver: 3.1.2

command run
 $ '''rsync -avh -e ssh --progress --rsync-path=/usr/local/bin/rsync admin@remotehost:/home/johnsmith/bin/test.csv ./'''

 admin@remotehosts's password:
 protocol version mismatch - is your shell clean?
 (see the rsync man page for an explanation)
 rsync error: protocol incompatibility (code 2) at compat.c(62)
 rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
 rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.2]


==solution==

get the protocol number of sender
 $ '''rsync --version | grep protocol'''
 rsync  version 2.5.7  protocol version 26

set the protocol number to match the older version of the sender
 $ '''rsync -avh -e ssh --progress --protocol--rsync-path=/usr/local/bin/rsync admin@remotehost:/home/johnsmith/bin/test.csv ./'''
