Server under TLS FTP loose connection and error showed by WinSCP is:

Code
Using TLSv1.2, cipher TLSv1/SSLv3: ECDHE-RSA-AES128-GCM-SHA256, 2048 bit RSA, ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AESGCM(128) Mac=AEAD

Disconnessione dal server

Copia file lato remoto fallita.

Seems pure ftp is trying to use SSLv3?

FTP under TLS give so many disconnections to me.

Hi peopleinside,

It seems that pure-ftpd is using TLS 1.2v from your machine , but also accepts connections via SSLv3.

I suggest that you change your pure-ftpd conf located at
/usr/local/apps/pureftpd/etc/

Change the following line in the config file :

TLSCipherSuite HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3

to

TLSCipherSuite HIGH:MEDIUM:+TLSv1:!SSLv2:!SSLv3

The above setting will force Pure - FTPD to only use TLS cipher suite for connection and not accept connection from SSLv3 cipher suite.

Hope this helps

I have already disabled SSLv3 on pure-ftp.
Now I will try the new pure-ftp update made some day ago.
