I am trying to get a folder on my computer (windows xp sp2) onto a linux server (fedora core 4). How do i do this? In the past i uploaded it to a web hosting site and used wget, but this file is too large to do that.

1) the target Linux must have FTPD running which will open ports 20,21
2) on your system, you FPT $target-ip-address (or domain-name)

you will need a login on the Linux system and need to give your user-id and password

upon logging in, issue passive as the first command.

be sure you're in the right transfer mode for the type of file being transported;
ascii for text files, and binary for all else

If both of these computers are yours, heck with it and just set up a samba share on the linux box. Not that hard to do and then you never have to worry about transfering with commands. Just drag and drop.
