How to configure and use rsyncd?

I get the same error and when Im looking in the log file I get this message:

secrets file must not be other-accessible

So probably you have to change the permission of the file.

Look in /var/log/rsyncd.log. Maybe the perms in your "/etc/rsyncd.secrets " file are too wide.

The answer by schemanen is correct, however you have the option to disable strict modes in rsyncd.conf without removing read permissions from the secrets file from other users.

in your /etc/rsyncd.conf add:

strict modes = false

and finally restart the rsync daemon.
