I turned on ftp in sharing (mac 10.3.4) but i can't login from my other machines. It complains that the login (password?) is incorrect. But i'm sure I typed it right.
Do a test. Turn on Personal File sharing and try to connect via that. They use the same password. If you are unable to log in that way, you're probably not typing your password right, or you're not using the proper short user name.
