titleDUO Dual Facter

Duo dual factor authentication is required for SFTP and SCP to work. Ensure that you have a default request method for duo to authenticate.


Note
titleNon-interactive shell output

Your client software will first try to establish a non-interactive session on the server. It will fail with an error if the non-interactive portion of your shell's startup prints anything. For the common case of bash, your ~/.bashrc configures non-interactive sessions, so make sure it contains no modifications which cause output. It's safe to place such modifications in ~/.bash_profile which only configures interactive logins.

This process is more involved in that one must create the directory remotely first and then transfer the contents from one to the other – wildcards are helpful for this.
