Is it possible to configure vsFTPd or other server to use (1) SFTP over port 22 (2) be encrypted but only require username and password. What is the "https" equivalent in the SFTP world. I don't want to copy a cert to every machine that needs to call into my server.
Is there a combination of settings that can achieve this? I thought I had done this before when I needed to copy files to a location and needed all the traffic to be over a single port for a picky firewall. I'm currently working on a vsFTPd server and can't seem to get this last piece of configuration correct.
