What I Learned in Computational Physics
You will be issued a username and a temporary password by the instructor of the course. The first thing to do is to change your temporary password. You can do this by logging in to one of the machines in the classroom using the username and temporary password. Once you are logged in, open a new terminal window,this can be done by clicking on the redhat on the menu bar, then click on the system tools, then click on "new terminal." Once you opened a new terminal type yppasswd to invoke the password changing program. It will first ask you for your old password, then will ask you for a new password. Try to choose a password that is easy for you to remember.
In case you would like to access your account from a remote location you can telnet to gauss, if you are using Windows this can be done by clicking on the Start menu and under Run type telnet gauss.pa.msu.edu, then enter your login name and password.the same can be done under the prompt for UNIX if using UNIX. If you prefer to work under a secure shell you can do that by typing: ssh BPS1240-xx [program] where xx is the PC number from 01 to 10. We should mention that this command will work only on the machines in the classroom and in case you have a computer that you use frequently to connect to the cluster then you should download and install the secure shell.
All the machines in the classroom are using RedHat 6.0 Linux, so if you are not familier with Unix, we advise you to read the Unix online manual first. Or if you want a quick reference for Unix, you can check my Unix Cheat sheet which contains the most common used commands in Unix. While worknig in Unix you will need to edit text, there are many text editors for Unix like Vi, emacs, pico editors, but the most common one is the Vi editor which will be found in any Unix system, so we prefer that you learn it and master it first. You can learn how to use the Vi text editor by referring to the Vi online manual. Or if you like a quick reference for Vi text editor, then you can check my Vi Cheat Sheet
