I've got a data logger from Logic Beach "Intellilogger" that I will be using for a solar energy project. It has FTP capabilities. I have made a dummy data logger function that records date, time, and internal CPU temp.
On the Pi side, I've set up a vsftpd server. I chose a directory /home/pi/ftp to have write access. When I test my ftp connection through FileZilla, everything works fine. I can read/write to the directory. After configuring the data logger with the same connection details it doesn't work.
I spoke with an engineer at the manufacturer and sent him the log files, this is what he replied:
The logger is getting the following when attempting to connect to the server:
"SSH-2.0-OpenSSH_6.7p1 Raspbian-5+deb8u3" which is not a valid response.
The logger is expecting a 220 FTP response, something like:
"220-Cerberus FTP Server - Home Edition"
Manual to device: (choose the third option) http://www.logicbeach.com/manuals/
Can anyone help? It sounds like the RPI FTP isn't compatible. Can I change this 220 FTP response to this valid text? Will changing to another FTP server help?
