After i placed the script on the router in the "root" directory as adviced by the guide (via winscp) and tried to start it via PUTTY .. i already failed. Putty does not see any file. Putty tells me i am in the root directory .. but i wonder what "root" is meant. i put the file in the visible "root" dir .. and in the current visible folder that might be "root" as well.
i am aware this is a bloody beginner questions, but I did not find out the solution in my research in the forum. thank you
The file was not transferred (or if it was, it was put in the wrong place). This is not an openwrt issue, though. It would have to do with your winscp session.
Edit - it looks like it was transferred to the root, /, not /root/.
