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.

How can i rsync over my network without using ssh? (discuss.tchncs.de)

I have 6 devices that i rsync to a central location to back them up. Ive been using ssh as the -e option. Problem is i use public key with passphrases, meaning to backup all six i need to go to each device and run the backup script. Since i typically backup /etc, /home, and /root this means entering sudo and the ssh passphrase 3x for each device.

I would much prefer a script that runs on back storage device that can pull the data from each device without having to use ssh (encryption is not necessary since all traffic is either local or going through a vpn connection).

I could then put this script in root's crontab or make it a systemd service running as root.

But i dont know how i can remote sync without ssh

You can create a second SSH key without passphrase, add that to the authorised keys, and specify to use that key instead, for example using an SSH config file.

Now this is a bit of a security flaw because anyone with access to the key can use it, so you can use rrsync to make sure that key only has access to rsync, so worst case scenario it can destroy your backup, but that's expected since you want write access to your backup without inputting a password.
