sshfs uses sftp-server to communicate with the server. with the optional flag -o sftp_server=SER I can define the path to the sftp-server on the server (in my case CuBox). But the problem is, that no sftp-server can be found
sh: /usr/libexec/sftp-server: not found
So my goal is to get a sftp-server on the CuBox. The easiest way is to install the package openssh-sftp-server but is not available.
