What is FTP ?
• FTP is the abbreviation for
File Transfer Protocol
• Used to copy files between computers
• You must have an FTP client on your
computer (such as WinSCP)
• The remote computer must be running an
FTP Server
What is sFTP and FTPS?
• Although still widely used, FTP is considered
insecure; usernames, passwords, and files
are sent unencrypted (plaintext) and easy to
“snoop” or even modify
• sFTP is a version of FTP built into SSH (along
with “scp”), and is widely supported
• FTPS is regular FTP through an encrypted
tunnel, and works similarly to HTTPS
• The HCC Student Webserver supports FTPS
What is WinSCP?
•

software; see osXdaily.com for
instructions

3. Enter the required information to connect to
the Student web server (figure 2)
4. Save the session information (figure 3)

Understanding the
Session Window
• On the left side of figure 5 are files on
your hard drive (local)
• On the right side of figure 5 are files on
the remote computer (remote)
• You need to change the local folder to
where your website files are. In figure 6 I
navigate to “My Website” folder on the
desktop. Figure 7 shows the result

Updating Your Web Site
• Start WinSCP, enter your user ID (folder
name) and password, and open your
folders as before
• Click on images or other files on your
computer (local) to select them
• Select updated and new files from the
left, and upload by dragging
• Right-click on a file to rename or delete
it
Updating Your Web Site (cont.)
• To modify a file that is already
uploaded, just upload the modified copy
and it will replace the original copy
• Download by dragging a file from the
remote (right) to the local system (left).
This file can then be modified and
uploaded again
• Always check your web site after
modifying it, by using your browser’s
refresh (or reload) button
Summary
• Upload just your files, not the folder containing your
files
• The top (main) web page must always be named
“index.htm” or the web server won’t find it
• Use URLs of just filenames (such as “foo.gif”) and
not pathnames (such as
“C:\Users\student\Desktop\folder\foo.gif”)
• Be sure to use the file’s full name, including the
extension
• Look in the feedback comments for the Web site
Concept project for your FTP username and
password
