how to force accept only ssl connections in vsftpd?

ftp, linux, ssl, vsftpd

Solution

If you set "force_local_logins_ssl=YES" then your clients will be required to use an FTP client that supports AUTH TLS/SSL in order to connect. If you leave it at "NO" then people can connect securely or insecurely.

Source

All you need to do is change that setting in `/etc/vsftpd.conf` or in `/etc/vsftp/vsftpd.conf`; depending on your distro, the `.conf` file should be on of those 2 places. Then all you should need to do is restart `vsftpd` daemon as so:

vsftpd restart

EDIT

You may also need to set `ssl_enable=YES` for this to take effect (as pointed out by Tegran in the comments)

Problem

I did install and configure `vsftpd` with ssl using openssl. But I want to accept only ssl connections, or, in other words, deny non-ssl connections.
