[BlueOnyx:16233] Re: FileZilla unable to connect using implicit TLS

[Jim Scott]

Thanks Michael,

What threw me off is the help text when you hover over FTPS describes port 
990 which I believe is typically associated with implicit TLS? After reading 
the help text furhter I see it suggests using explicit, but I believe the 
port 990 should be removed as I believe with explicit it communicates still 
over port 21 ?

Also if I am correct in my understanding then these options should be 
commented out in /etc/proftpd.conf ?

TLSOptions UseImplicitSSL
Port 990

Also I wonder if SSLv3 should be removed by default since it has been 
identified that it contains a vulnerability (poodle attack) ?

Hi Jim,

> I can connect fine using explicit TLS, just not implicit.

Only explicit TLS is supported. That way people have the choice to use
"standard" FTP without encryption or explicitly ask for a secure TLS
connection.

If we would enforce implicit connections, all unsecure connections would
be dropped outright and only those who outright connect with the secure
protocol are allowed to proceed.
