Unix - ISY & MAI
If you log on to a computer at ISY or MAI you will be presented with a graphical interface.
Behind the screen on the Linux systems (MAI/ISY) works CentOS.
Your personal files is located in your home directory.
Important to notice is the procedure when you log on to the MAI or ISY system. This can be done either by log on from a remote system or use the graphical interface. On the Linux system Gnome is one of the window managers. However, if you choose too login remotely, you will have to use ssh which is the only remote client allowed. Then you will be presented with the UNIX prompt and have to control the computer by using commands.
This happens when you:
Log on via the desktop
The system starts by reading your '.cshrc' file in your home directory. This file contains setup instructions for your computer. Then the computer reads your '.isy/csh/cshrc' file if you are on an ISY computer or '.mai/csh/cshrc' if you working from a MAI computer. The file '.login' is not read by default when you log on to the computer.
Log on remote
The computer starts up the system by reading your '.cshrc' file. It then continues by reading your '.login' file.
A word of warning is that you have to be very sure of what you are doing when you change your system files, if you're not, then don't. If your system files are not working properly this can result in difficulties when logging in.
If your system refuses logging in, an error in the system files can be suspected. Then choose the Options>>Sessions>>Failsafe item on the login-screen, login and correct the error.
