SOLVED FTP Issues

[NoHesHere]

So, after having searched all over the place, I thought I might post here for some help. I have configured SSH access using keys, and it works without issue. I have enabled FTP, and connecting via SFTP does not work. I thought the issue might have been OpenSSH version related, as I was on 9.3, but even after upgrading to 9.10, I see the same issue. Here is the output, let me know if you can help, or if you need anything else from me.

Code:

Were you able to figure this out?

I have enabled FTP, and connecting via SFTP does not work.

Did you enable SSH? SFTP connects over SSH so make sure your connection credentials on the client are configured accordingly.

 

[NoHesHere]

Yea, it was exactly what Jailer said. Turns out, that even though you configure an FTP port in the service, if you connect over SSH, it has to use the SSH port. Makes sense really, but I wasn't expecting it for some reason.

 

[Robert Trevellyan]

Perhaps you don't realize that SFTP is a complete (and superior) replacement for FTP. In other words, if you have SSH set up, you already have SFTP, and you no longer need to think about FTP.

 

[NoHesHere]

I was aware that SFTP was a better option than FTP, but not that it was a replacement wrapped into SSH. I was under the impression that I needed to run the FTP service along with the SSH service, in order to get the functionality I was looking for. :)
