problem

rsync transfers are failing due to a version mismatch

sender: 2.5.7
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=26 --rsync-path=/usr/local/bin/rsync admin@remotehost:/home/johnsmith/bin/test.csv ./
