You are required to have completed the objectives in the Lab 0 before doing this lab.
From this lab, you will learn how to store on and retrieve files
from a remote computer named
For this course, you are required to publish all of your completed
assignments (homeworks, labs, and projects) on the web, with certain
exceptions. This means that you will be required to place all of your
dante and have your web publishing area
activated. If your web publishing area is not activated or if you do
not know if it is activated, complete
Lab 0 before continuing with this
In general, you should not use floppy disks for your assignments.
They are unreliable and have a tendency to become unreadable when you
need them the most! Instead, use a reliable remote computer (such as
dante) to store your important data. You have been given
100 MB of disk space on
dante, which should be more than
sufficient for this course.
A directory is often also called a folder or, less commonly, a catalog.
To be able to find directories and files on your local computer, you must understand how to navigate through the computer's directory structure. This section explains how to navigate through a Windows environment on the local computer.
The local computer is the computer your keyboard is attached to.
You can open Windows Explorer using one of the following methods:
C:\My Documentsor some other similar directory.
C:\Documents means a directory
Documents on a hard disk drive named
C:\Documentsby first clicking on the
Cdrive and then clicking on the
EraseMe. The directory should be empty.
C:\Documents\EraseMe\testFile.txton a local computer.

Desktopis actually a directory on the hard disk drive named
My Computeris not a directory and, therefore, can not be the root of a directory structure. It is Microsoft Windows method for grouping together the different parts of the local computer.) Other root directories on the local computer are
A:(for the floppy disk drive) and
D:, if it exists.
To be able to find directories and files on a remote
computer, you must understand how to navigate through the remote
computer's directory structure. This section explains how to navigate
through a UNIX environment on a remote computer named
dante, using a graphical SFTP program named SSH Secure File Transfer.
SFTP stands for Secure File Transfer Protocol, which is a standardized method (protocol) for transferring files between computers in a secure/encrypted manner.
A remote computer is a computer that you can access (e.g., through a computer network like the Internet), and is not the computer your keyboard is attached to.
dante.u.washington.eduand for the user name, enter your UW NetID. If your UW NetID was
smith, you would enter the following:
Enter your password in the next pop-up window to finish connecting
dante. In the smaller window on the right, you can see the entire directory path of your current location on the remote computer, e.g.,
/nfs/guido08/smith. (When you first connect, you will always start in your home directory, which should have the same name as your UW NetID.) There is a similar small window on the left, which corresponds to the directory path of your current location on the local computer. It should currently be empty.
The gray bar located at the bottom of the window is the status bar. It tells you if you are connected to a remote computer, which computer you are connected to, etc.
You can learn what an icon represents by positioning the mouse over the icon.
public_htmldirectory or your
student_htmldirectory on the remote computer by double clicking on it. If this directory is empty, the right window should become empty.
If you go down into the wrong directory, you can go up and out of it by clicking on the Up icon .
student_html) directory is a web accessible directory.
You see the contents of this directory when you go to
fit100inside of your
student_html) directory. You can use one of following methods:
fit100 directory is the
directory where you should put all of your assignments for this
fit100directory. You will need a directory for this lab, which should be named
lab1(since the lab is called Lab 1).
fit100 directory structure should be similar to
the following, minus the files:
To make your assignments web accessible, which is
required for all completed assignments in this course, you must place
them in your web accessible directory on
This section covers how to upload and download files and directories to and from a remote computer.
Upload means to transfer files/directories from your local computer to a remote computer (local –> remote). Download means to transfer files/directories from a remote computer to your local computer (remote –> local).
dante, which should be in your
dante. This can be done by using one of the following methods:
When you are done, close all SSH windows to log out from the remote computer. Finally, log off the local computer before leaving.
