Using GOPHER to obtain lecture notes and homework assignments.
GOPHER servers, running on the CAPA machines, will be used to distribute homework assignments, lab instructions, and other course information. These servers can be accessed from anywhere in the world. GOPHER is a document retrieval system that allows the users to retrieve documents from the server machine and store them on the client machine. You can retrieve these documents, save them on for example UHURA, and/or send them to one of the postscript printers. GOPHER is available on most campus machines (in case of doubt, please contact your system manager). To access the GOPHER server from UHURA you type:
lynx gopher://phobos.nsrl.rochester.edu/
If lynx is not installed on your machine try
gopher phobos.nsrl.rochester.edu.
In the following example I will assume you are a Physics 113 student. The retrieval of assignments and laboratory manuals for students in other courses will be identical. After the connection is established your screen might look something like this:
==============================================================================

The actual layout of your screen depends on the machine you are working on, and
the content on the screen might vary from semester to semester as different
courses use the GOPHER system. You see that there is a directory called
Physics_113. Use the cursor keys (up and down) to highlight to the Physics_113
directory. Hit the return or enter key to retrieve the contents of the
Physics_113 directory. Your screen will now change and look something like
this:
==============================================================================

==============================================================================
You see now that there are several different directories (and the number and
type of directories will be different for each course). To get your homework
assignment you select "Homework_Assignments" as the directory. Your screen
will now look something like this:
==============================================================================

The assignments are placed in the appropriate directories at the time announced
by your instructor. They will remain there until the end of the semester. Use
the cursor keys to point at the directory containing the assignment you want to
retrieve and hit the return or enter key. If you want to retrieve assignment
1, your screen will now look something like this:

Move the arrow to point at your assignment. (Note that the top right of the
screen indicates that this is page 1 of a total of 12, indicating that more
assignments are available on the next pages.) To move to the next page you can
use a space. When the your assignment is highlighted, hit P for print. Your

Note: since the postscript files are in general very large, it is best to directly print from the GOPHER menu (rather than first saving and then printing).
The GOPHER server is also used to download the lab manuals for the lab experiments associated with PHY113, PHY114, PHY121, PHY122/142, and PHY123/143. To download the lab manuals select Physics_Labs from the GOPHER menu:
