I had to do some testing for a project that uploads its payload via SFTP. I wanted to setup a basic, no-frills SFTP server that could accept my files. I did a quick Google search and found Core FTP Server–a free download. After about 2 minutes of configuration, I had my SFTP server up & running; it was fantastic.
I also see that they have a free mini sftp server that’s available. It’s a no-install, one-user, one-directory SFTP server, and IT WORKS AWESOMELY! This might be my new favorite way to securely transfer files between sites!
