When using the demo images and attempting to use WinSCP or some other sftp application you may get an error like

“Cannot initialize SFTP protocol. Is the host running a SFTP server?” from WinSCP or

“Connecting
[SFTP] Host key accepted
[SFTP] Successfully authenticated
[SFTP] Error initialising sftp: Access denied. Authentication that can continue: publickey,password
Unable to connect”

from Notepad++

This is due to demo images not including the openssh-sftp-server package by default

To install login to the Beaglebone using SSH (via putty) and run

opkg update

opkg install openssh-sftp-server

Your WinSCP or Notepad++ or other SFTP application should now work nicely
