RSYNC

[Jose]

Hi

I want to send copy from raspberrypi to a remote server with rsync to update my website with last changes.

I have verified that I can connect via ssh passwordless using public and private keys with no problem to server (ssh user@server)

The problem comes when I try to do the same with rsync; an error message says that the remote host cannot be authenticated and connection fails.

I have modified the / etc / ssh / ssh_config file adding the Host, User and Identityfile (path to .ssh keys) but nothing changes.

What can I do?

Hi,

By default the WeeWX daemon runs as root, so unless you have changed this root needs passwordless ssh access to the server to which you wish to sync your files. Did you give root passwordless ssh access or was it some other account? If this is the problem you have two choices; either change WeeWX to run as the user you have given passwordless ssh access or keep WeeWX running as root and give root passwordless ssh access.

The wiki article ‘Run WeeWX as a non-root user’ (https://github.com/weewx/weewx/wiki/Run-as-a-non-root-user) provides instructions on how to run WeeWX as a user other than root.

Hi, 

remote hosting is updated with new files using RSYNC from WeeWX, thank you, but if I am having some problems when I try to do it with 

 rsync -a --delete -e ssh /home/pi/backup.tar.gz  user@ssh.hosting:/www/backup/ &> /dev/null

this command worked fine in the past but not now. When I run this command nothing happens, no updating remote hosting and even no error messages. so RSYNC with WeeWX is working fine but RSYNC in command line don't.

My apologies, I thought your problem involved WeeWX rsync not working.

I assume you are trying to execute the command below from the command line on your WeeWX machine. As I pointed out in my previous post a common issue is that passwordless ssh has been setup for a given user account that is different to the user account that is later used to execute the rsync command. Are you sure the correct user account (still) has passwordless ssh access? If you are convinced this is correct my only other suggest is to look at the logs on the target server to see if you can find any error/reason for rejection.

This works for me....

rsync -ruva --delete -e "ssh -l root -i /root/.ssh/id_rsa" ro...@192.168.2.2:/backups/ $FILELOCATION/dmz/

Just focusing on your statement that you see no errors with the above command.
It's doing exactly what you've told it to, that you want no feedback
from it, ever. It's dead to you.
Send whatever it has to say (&>) to the bit bucket (/dev/null)

Remove that redirect that you have on the end and it will probably
offer up a few clues.

rsync -a --delete -e ssh /home/pi/backup.tar.gz us...@ssh.hosting:/www/ backup/

hi Glenn

you are right. rsync -a --delete -e ssh /home/pi/backup.tar.gz  us...@ssh.hosting:/www/ backup/  it is working fine now. thanks.
