Log in

I am writing these instructions with the assumption that you are sitting at one of the SGIs in the Mudd Lab or the Schupf Lab. You can also log in from a Macintosh, Wintel or Linux machine, but I will assume if you are using one of those systems that you know how to create windows and connect remotely.

1.

Get a piece of paper from me that has your account name and password on it. The account names are in the form os1 through os25. These accounts exist on the SGI machines with the names iris4 and iris5 (the machines in the Mudd Lab), iris6 through iris11 (the workstations in the Schupf Lab) and iris12 (the Power Challenge in the Schupf Lab).

2.

Log in to the machine. The first time you log in, the window manager may tell you that you have no environment set up, and it will ask you if you want to create one. You do.

3.

The default environment will create a window with lots of icons in it. If you figure out what it's good for, let me know. Otherwise, just close it.

4.

From the desktop menu, select ``UNIX Shell.'' It will create a window with the standard UNIX command-line interface. Commands you execute in this window will run locally, on the machine you are sitting at.

5.

Also from the desktop menu, select ``iris12.'' This will create a remote login window, and automatically log you into iris12. You should not have to type your password; if you do, there is something wrong with the setup and you should let me know. Commands you run in this window will run on the Power Challenge, which means that they will run much faster, unless iris12 is very heavily loaded.

6.

Your home directory, which is where you will do all your work, is available from all the SGI machines. Thus, most of the time it does not matter whether you execute a command locally or remotely.

7.

In the local window, type netscape & to start a web browser in the background. After a few seconds, the browser window will appear. Load the following URL: http://rocky.colby.edu/cs357.

8.

Read the course information there, if you haven't already, and then go to the UNIX help index. You will probably want to bookmark this page.

9.

Find the documentation of the pwd command and read all about it. Run it to find out the complete path of your home directory. Make a note of it.
