HTTPS Post (sending data to a secure server which accepts only SFTP or HTTPS)


Eugen Nov 15, 2013 02:21 PM

Hi all,

We want to send data from a data logger (CR800, CR1000) directly to a server, which accepts only SFTP and HTTPS Post methods.

From what I understood, SFTP is based on ssh protocol. Is ssh implemented in any way on the data logger? Do you know of any attempts to implement SFTP on data loggers?

On the other hand, HTTPS is the same HTTP, but with a SSL/TLS encryption over-layer. I saw that TLS is already implemented in data loggers' OS, and it can be used in FTP transfer, Email or PakBus communications. However, it is not clear to me if I can use HTTPPost() using TLS. If I set the "TLS enabled flag" to true, will the HTTPPost() function also use TLS encryption when posting data?

Thank you.

Greetings.

The logger does not support sftp. To my knowledge there is no plan for implementing sftp or ssh. If you and others feel strongly that we should be working on sftp and ssh implementation please let it be known here. I can't promise anything but I do know we have gotten regular feedback about implementing openssh compatible methods.

The logger can be a https client. If your code includes a https destination in the http put/post/get instruction during compile time the logger will setup memory for that process correctly.

The two protocols FTP and SFTP are used to transfer data reliably between computers, and also secures connections with encrypted SFTP,FTPS or HTTPS. This allows you to configure the server to only accept encrypted FTP connections.

Sam, our university runs an FTP server for us to store data on, but they won't allow us to access it with dynamic IP addresses. They want us to use SFTP. So, yes, we'd be interested in an update to enable that to work.

Sam. We use CR1000s on our Australian oceanographic buoys. Unfortunately, government and university clients only permit data uploads to their servers via SFTP. SFTP support for CS loggers is now essential. Clive.
