![]() A command-line client (unsurprisingly called sftp) comes standard on every Apple OSX or Linux system. What’s required to use SFTP is some client software. Not a big issue with your "classroom" server - but it's an unacceptable risk if you're remotely administering production servers. Finally, while old-style FTP is still very commonly used, it sends login credentials "in clear", so that your flatmates, cafe buddies or employer may be able to grab them off the network by "packet sniffing". It's also very likely that restrictive firewall policies at a workplace will interfere with or block these protocols. Not only that, enabling extra protocols also increases the "attack surface" - and there's always a chance that you’ll mis-configure something in a way that allows an attacker in. If you’re successfully logging in via ssh from your home, work or a cybercafe then you'll also be able to use SFTP from this same location because the same underlying protocol is being used.īy contrast, setting up your server for any of the other protocols will require extra work.
