Now, I'm trying to figure out how to disable DES and 3DES for Pure-FTPd. I changed my TLS Cipher Suite to:
#sslyze --starttls=ftp --regular 162.209.0.20:21
When I test my server with SSLyze, I still see this weak cipher listed:HIGH:!SSLv2:!ADH:!DES:!3DES:!aNULL:!eNULL:!NULL
#sslyze --starttls=ftp --regular 162.209.0.20:21
TLS_RSA_WITH_3DES_EDE_CBC_SHA - 112 bits
