Computer Use - basics

Computer Use for CS4984

Many computers will be of use in this course, in a variety of capacities.

Devices to Get Connected to Internet

• Your own computer may be on the Internet or may be connected using SLIP.


• Systems in labs are generally on the Internet.


• X terminals are on the Internet but must connect to some computer to be of use.

Computers to Run Mosaic From

• Your own computer may run Mosaic, if it is a Mac, PC, or UNIX type system. If not present, simply get the latest reliable version from NCSA.



• Most lab systems will run Mosaic.


• From an X terminal you can login to a computer running Mosaic and set the display to come to the X terminal. If you do not have a computer account for this purpose, you can use fox.cs.vt.edu or ccrd1.cc.vt.edu as long as not every student does so at once.

Principal Uses of Various Computers

• video.cs.vt.edu: is a server for Hyper-G and KMS or can be logged into. It runs xprcedit for viewing page images, and sqhm for editing HTML documents.

Using X Terminals

Then set the display to
   your terminal with:
   setenv DISPLAY name.cs.vt.edu:0.0
   In most cases you will use Mosaic (sometimes called xmosaic or mosaic).


3. To end your sessions: Log out of or close ALL windows and session managers. Choose the Quit option under the Session menu of the VXT V1.0 window. Verify that you want to quit.
