There are two authorized_keys...
original: \system\etc\ssh\authorized_keys (ro)
and a copy : \data\ssh\authorized_keys (overwritten at every restart)
I had no idea how to get my key into the original \system\etc\ssh\authorized_keys,
so i add it to \data\ssh\authorized_keys on every restart with the entry in the start_rigol_app.sh
Both solutions work, but adding the key to the original \system\etc\ssh\authorized_keys is of course the better solution
