FTP over SSH (aka SFTP / SCP)

[chotaire]

FTP over SSH can be accomplished by using SSH forwarding which is e.g. supported by the free client PuTTY. You can easily use PuTTY and FlashFXP together but keep in mind that this is very difficult with passive ftp connections because of random ports being in use. Active connections will work fine without much work.

If I am out of topic, forgive me ;-) I hope you were referring to FTP over SSH, not SFTP.
