The profile will be downloaded and saved in the “Profiles” folder of the application support directory right away. To install a connection profile simply enable the corresponding checkbox. You can either scroll through the list of profiles or use the Search function. This should make it much easier to connect to various hosting and cloud storage service providers without the need to lookup connection details other than credentials. Limiting the connections to '1' should force FileZilla to use one connection (and thus one authentication) for the entire transfer.Cyberduck 8 and Mountain Duck 4.8 introduce a new Profiles preferences tab that allows to install additional connection profiles on demand. When transferring multiple files, FileZilla tries to open multiple connections, and it's doing the interactive logon for each new connection it's opening. In FileZilla, under transfer settings, limit the number of simultaneous connections to '1'.To avoid this go to preferences > general > Transfer Files: 'User Browser Connection' then connect to the cluster via SFTP. Note: By default Cyberduck will ask for multi-factor authentication on every file copy transaction.If using a yubikey, you can touch it when prompted to complete the login.You should be prompted on you cell phone to allow the connection.In the 'Provide additional login credentials' box, enter 1 in the password field and hit enter if using the smartphone app.enter you username and password, then click connect.Cyberduck can be made to work with 2 factor.Type scp local_filename To copy files from the central cluster to your computer.

Type scp local_filename To copy files from to the central cluster to your computer.

To copy files from your computer to the central cluster.Start Terminal (Applications->Accessories->Terminal).There are implementations available for all common operating systems including Linux, Windows, and Mac OS X. SCP and SFTP both run over ssh and are thus encrypted. Using SSH/SCP Why use SSH/SCP/SFTP for file transfer?
