Hi there,

at [1], @MKO1640 outlined some problems connecting to his Synology Diskstation using rsync with SSH key-based authentication.

With kind regards,
Andreas.

In general, storing SSH passwords in plain text is considered very insecure. In turn, ssh does not provide such an option on its own.

However, those resources talk about the sshpass program which might still enable supplying the password to an SSH invocation in plaintext, in order to work around this.

Those resources, however, describe how to configure a Synology NAS to use SSH key-based authentication.

I believe following the second option would be the most promising way, because it a) will retain security by following general best practices and b) will not need any adjustments to the code of Saraswati.

Please let us know if this works for you, @MKO1640.

Hi again,

according to [1], I think @MKO1640 has been successful with this procedure, right? If so, I believe we can close this ticket.

With kind regards,
Andreas.
