I am fairly new to command line and rPi, all previous experience has been desktop & web apps and have fallen at a major hurdle with my new Pi.

As the title suggests I am struggling to sftp into the rpi with the final intention of controlling GPIO via a web app. most importantly I can log into the pi successfully using SSH terminal for mac.

  1. Pi is connected to router via ethernet and I am running my laptop over wifi
  2. Pi has a static IP, this has been confirmed over router.
  3. Not sure if it was necessary at this stage but port forwarding has been setup on router.
  4. Ran pi updates/upgrades
  5. I have changed my password
  6. PasswordAuthentication yes in /etc/ssh/sshd_config
  7. connection via cyber duck gives this error: Interoperability failure: EOF while reading packet. Please contact your web hosting service provider for assistance.
  8. connection via filezilla gives me this error after previously saying connected: Received unexpected end-of-file from SFTP server.
  9. SFTP connection via terminal: asks me for my password then instantly says connection closed.
  10. Disabling router firewall made no difference so i reenabled.
  11. I was following this tutorial if that helps: tutorial

I have spent the most part of today searching the internet and so far no solutions have fixed my problem.

Being new to command line I am struggling to really delve into the debugging stage and not totally sure what I should be looking for.

edit: I have ran the sftp in terminal with -v

debug1: Authentication succeeded (password).

  • digitalocean.com/community/questions/… seems to describe the same problem and offers some potential fixes / workarounds. BTW: I don't have any problems with filezilla / sftp on a Windows machine. – Dirk Aug 20 '18 at 7:55

Thanks Dirk for pointing me in the right direction! For anyone else with this problem it was fixed by editing /etc/ssh/sshd_config.

Commenting out the line

# Subsystem sftp /usr/lib/openssh/sftp-server

And adding the line

Subsystem sftp internal-sftp

I then power cycled the pi for good measure and voila!
