Can you do an sftp session with FileZilla?
Yes FileZilla (tested using Windows version 3.7.3.) will act as a sftp client. Type sftp://<destination IP address> in the “Host:” field. Example of that would be “sftp://192.168.1.120”. Next populate “Username:” and “Password:” field with your credentials. Press enter then click ok button to accept that security fingerprint will be saved for that destination. After that you use FileZilla as you normally would.
