On new QNAP devices Entware-3x is used instead Optware or Entware-ng.


In Download section you can find the install file.

On QNAP go to App Center and select manual install, browse install file and that's it, after the install, restart QNAP.

I connect with putty (ssh) and install what I need:

opkg install coreutils

opkg install findutils

opkg install bash

opkg install cron
