Before the lab in this week, i ever know there is a clever software “hide” in Macbook—Cyberduck.
It is a popular free and open source FTP client for the Mac. It is developed by David V. Kocher, and has been used extensively by Mac users since 2003. Cyberduck isn’t simply another knock-off FTP client, rather it takes a very Mac-like approach to file transfer.
All characteristics are here:
Secure file transfers with Secure FTP and FTP-SSL.
Easy file management with cut and paste as well as drag and drop.
File previews so you can view the files before you download them.
Password-less authentication with ssh keys.
Password integration with the Mac Keychain.
Futher more, this website has some extra links about this software.
