FTP

This page explains the use of File Transfer Protocol (FTP) for transferring your file(s) between a local computer and a remote computer (perhaps a web server).   FTP is supported in both MS-Windows and UNIX.  The GIS lab machines have a Secure Shell FTP client program that is very easy to use.  You can also run an FTP session from a UNIX command line or the Windows command prompt

To transfer files between your lab computer and UD's copland server, start the program, and in the Connect window specify copland.udel.edu as host name and enter your login name.  The next window will request your password.  Once you are connected, you get a window like this:

The left frame lists directory contents on your local computer, the right frame lists the directory contents on the remote computer.  Navigate to the appropriate source and target directories in the two frames, then simply drag and drop files or folders between them.

To change permissions on a file or folder, simply right-click its icon and change its properties:


The FTP client will also let you rename or delete files, create new directories, etc. on both the local and remote machines.

FTP has two transfer modes, binary and ASCII (notice these icons on the top row of the program window).  The client program is pretty smart about figuring out which mode to use, so you won't normally have to worry about this.  Binary mode transfers an exact copy of your file; it's appropriate for everything except plain text files such as HTML  ASCII mode automatically converts text file CR-LF codes which differ on PC and UNIX platforms.  If you copy an image file as ASCII, the image may be corrupted.  If you transfer a plain text file as binary, it may have missing line-feeds or extraneous line-feed characters.
