Hello,

I'm trying to use rsync over SSH without the "-e ssh" option. The idea 
is to make rsync --daemon bind on the loopback on the Cygwin box and to 
connect to this box with a tunnel:

ssh -L 873:localhost:873 user AT cygwin_box

On the Cygwin Box, the file /etc/rsync.conf contains:

[d_drive]
         read only = yes
         path = /cygdrive/d/
         hosts allow = 127.0.0.1

To backup the Cygwin box, this simple command should do the trick:

rsync -avz localhost::d_drive /path

This is a simple use of a SSH tunnel.

Unfortunately, on the cygwin box, rsync sees the loopback connection 
(from the SSH tunnel) from its own public IP address instead of "127.0.0.1".

So the /etc/rsync.conf should be:

[d_drive]
         read only = yes
         path = /cygdrive/d/
         hosts allow = <real_IP_address_instead_of_loopback_address>

It works but I'd like to backup a lot of Cygwin boxes and having to fill 
the "hosts allow" line with a non-generic static value is quite disturbing.

How can I make rsync seeing local/tunnel connections as "127.0.0.1"?

Regards,

Nicolas
