Which USB-Serial Adapter and driver for ElCap

when using the ftp option (needed now as https is not currently supported for cronmetar)
it uses FTP login (anynomous login)
and it uses the ftp port number that your normal ftp uses
i.e port 21
that could be where the problem is
what do you have set as the ftp port number in the connections setup in WD?

Port 21.

The connection is made fine. It’s when cronmetar and ftpdown tell the server to send the file. That’s when the Permission Denied error shows up. You can see it I the capture I posted. You see the IP address of the server with ftp appended to it since I’m using the standard ftp port.

At this point I can get the file myself. Does cronmetar do anything to the fore after it’s downloaded to the metar directory?

if it works here, and it does work for others (have not seen otherwise) , and you say you are getting a permission denied error, then that points to something on your end , I would think

nothing else is done to the file
