Hi,

I need to setup a Rsync server to backup a 😡 NAS.

So I want to run it under SSH.

man rsync

Also note that the rsync daemon protocol does not currently provide any encryption of the data that is transferred over the connection. Only authentication is provided. Use ssh as the transport if you want encryption.

but when I do rsync --config=/etc/rsyncd.conf --rsh=ssh --dry-run
I get:

rsync: --rsh=ssh: unknown option (in daemon mode) So there no way to specify that rsync daemon should run under ssh ?

Also is this following A.I statement is correct ?

The rsyncd.conf file is only used when the rsync daemon is running on the remote host and the client connects to the daemon directly, without using an SSH connection.

So there is no way with Rsync (under ssh) to set settings (config file or other) that will apply to all clients !!??
So it’s the client that configure rsync and the server !? there is no way around ?!

    Given that you can already use rsync over ssh, I suspect you want to allow the rsync configuation options on the server side, but still use ssh to secure the transit. I would do it like this:

    • Configure rsync on receiving server to listen only on 127.0.0.1 (localhost).
    • Use ssh to create a tunneled port between your sender and receiving rsync server.
    • Rsync on the sender to [rsync defined user@]localhost:port (whichever port you set the tunnel up on) as your target.

    That would encrypt the traffic over your ssh tunnel, but still allow you to use the receiver’s rsyncd paths.
