Hate OS X’s Integrated FTP?
Well, MacDevCenter has an alternative:
"Muscle Up Your Mac FTP by Glenn Fleishman
— Here's a much better and vastly safer way to FTP on the Mac than using the built-in FTP software in Jaguar or Panther, which is an Apple-modified version of FTP software that works fine with other Unix variants, but has its problems on the Mac. Glenn Fleishman explains." Check it out. Looks interesting, although it will take a little bit of set-up.
If your FTP needs aren't this robust, you just want to access remote servers without allowing others to FTP into your computer, and you're too lazy to be bothered with all the set up, you could just download
Cyberduck for free and let it handle the FTP / SFTP basics for you.
