1) <b>FTPS</b> -- File Transfer Protocol Site... FTPs to work over port 990 on 2008 server... 2) <b>FTPES</b> -- File Transfer Protocol over explicit TLS/SSL... A client using FTPES connects to the standard FTP command port (port 21), and then makes an explicit request to the server to use SSL security. 3) <b>SFTPP</b> -- (SSH File Transfer Protocol) is not the same as FTPS (FTP-SSL). SFTP is intimately related to SSH, and has no relation, except in purpose and name, with FTP. Contrast with FTPS, which is simply the FTP protocol with SSL. The main difference is that SFTP only uses one stream, whereas FTPS, like FTP, uses at least two: a control stream, where the commands are issued, and another one for each data transfer. sathish...
