SSh is not parsing the port the way http does, it seems:

$ rsync -ah --stats root at 192.168.129.2:613:/etc/dhcp/ 
/home/rgm/data/htt/httnet/homebase/new/dhcp
ssh: connect to host 192.168.129.2 port 22: No route to host
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(226) [Receiver=3.1.1]

The reason why I change my SSH port is a simple way to keep port knocker 
robots away.  Different hosts use different ports...
