SFTP support for Real Time Targets?

Status: Completed

FTP is not installed by default on NI Linux RT cRIOs and it’s possible to securely transfer files over SSH using SFTP. 

As cRIO's are deployed in ever growing applications, it would sure be nice if there was an option to use SFTP (and disable FTP altogheter) on the controller. Ideally it would be supported at the OS level, i.e. the existing cRIO FTP server is upgraded or extended to include SFTP as well.

 

If this is already supported, try searching for "sftp" or "crio sftp" and you'll see only one 3rd party tool-kit, but I confirmed with that company (Labwerx.net) that it (labSSH) does not support cRIO/FPGA/RT targets and there are no concrete plans to add support to other targets.

 

NI: I call on you to either create the FTP toolkit I need to write my own SFTP server, or better yet, update the cRIO FTP server to include the "s". . . It is only one letter, how hard can that be!? 😉 Smiley LOL

 

If this is already possible through some (obscure?) way, please update your site-search engine to reckognize sftp and/or crio sftp, and/or link to a KB or Whitepaper on the topic as I did not find any.

(Note: cRIO safety and security IS covered in pretty good detail in the article series starting with Overview of Best Practices for Security on RIO Systems and the linked 3 articles.)
