* 2018-12-10 17:57:43.998 SFTP protocol violation: Invalid response message type (0).
The SFTP server violates SFTP specification by sending an invalid response to
SSH_FXP_REALPATH
request.
In turn, FileZilla is known to violate SFTP specification by not using
SSH_FXP_REALPATH
request, so it does not hit the server's bug.
