Hey folks,
I’ve got a nightly rsync data-backup running between Nethserver 1 and Nethserver 2. Data set looks complete, and I’m pretty happy with how it’s functioning, but I’m seeing some concerning things in the logs and I wanted to see if anyone had any insights on what might be causing them.
The internet connection between these two servers is VERY slow. So the backups frequently take a very long time.
As you can see in the logs below there are several “connection refused/timeout” and “no such file” messages. In case it matters, I have sanitized the logs a bit, and sshd is not running on port 22.
Thanks for having a look!
Ted
