Description
Ipswitch WS_FTP Server 5.0 introduced a new command
"CCC" ("Clear Command Channel") which is issued
immediately after authentication to signal that the
command channel should no longer be encrypted. This
allows for secure authentication via explicit FTPS,
while also allowing firewall FTP application
gateways/proxies to correctly handle passive
connections (as they can now see the passive response
from the FTP server behind them). Currently, only
Ipswitch's WS_FTP Pro client supports this command.
