How to install an SFTP Server on Arduino Yùn

By default, Arduino Yùn’s Linino has Dropbear, an SSH server that procides basic SCP but has no SFTP capabilities, so you cannot connect to the Yún with client software such as Cyberduck.

You can solve this basic issue by installing OpenSSH’s SFTP Server running this command in the Arduino’s SSH console.

opkg update    opkg install openssh-sftp-server

The server will be installed in /usr/libexec/sftp-server, exactly where Dropbear will look for it.
