From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Use Rsync Daemon with SSH !? (lemmy.ml)

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 ?!

So... As long as you have ssh running open on the receiving server, you don't need the rsync daemon. Rsync client will ssh, then execute rsync recipient automatically.

The daemon is only for if you don't want to or cannot run ssh really.

Is there a specific reason you are looking at the daemon, or just unfamiliar?

Using the daemon also allows you to transfer faster by removing compression and encryption. It tends to hit the same rclone speeds without the data corruption issues.
