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.
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.
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)
