ZOOHELP-1 Using Public Sun Workstations Page 1 This memo tells you step by step how to get on and off any of the workstations in the Public Sun Workstation Cluster once you have a registered username for the Public Sun Workstations. See section below BEFORE SIGNING ON if you need to know how to get to this point. If you have trouble with this procedure, see section below PROBLEMS DURING SIGN-ON, ask the consultant at the Public Sun Workstation Cluster (the consultants are sometimes available during working hours on weekdays), or call the Academic Computing Services HELP line (x2677). SIGNING ON A PUBLIC SUN WORKSTATION Here are step by step instructions to get onto a Public Sun Workstation. (1) If the workstation is off, turn it on. There are separate switches for the monitor and for the base unit: the monitor's switch is clearly visible just below the lower right corner of the screen (with a green power light and 0/1 markings: when "1" is depressed, the monitor is on); the base unit's switch is at the back of the base unit near the left-hand side, just underneath the power cord. After you turn on the device, it will display several pages of output, and finally display the prompt: Login:. The Login: prompt tells you that the workstation is ready for you to sign on. (2) After the Login: prompt, type your Public Sun Workstation username and press Return. The system prompts you with Password:. (3) After the Password: prompt, type your Public Sun Workstation password and press Return. Note that your password will not show up on the screen. The system will type a few lines of output and then will type the name of the particular workstation you are using followed by a percent sign (%). For example, on the machine called "sloth", it will type sloth% . (4) After you get the % prompt, type sunview and press Return. After a few seconds, the screen will clear and change to a gray pattern. Now you are ready to use the workstation, using Sunview. See A LITTLE ABOUT SUNVIEW below for some ideas about what to do next. For more information, refer to Sun Workstation manuals and other instructions. SIGNING OFF A PUBLIC SUN WORKSTATION Here is how to end your Sun Workstation session if you are using Sunview. (1) Place the mouse cursor in the background, then press and hold down the right mouse button. A menu (the background menu) will appear. (2) While holding down the mouse's right button, move the mouse cursor to the last line of the background menu marked Exit Sunview, so that the words Exit Sunview are highlighted. Let go of the button and wait. The menu will disappear and in a few seconds, you will get the percent-sign prompt, the name of your workstation followed by a percent sign (%). (3) At the percent-sign prompt, press D while holding down the Control key. The system will type a brief sign-off message, then will type the Login: JMW 5/89 ZOOHELP-1 Using Public Sun Workstations Page 2 prompt. You are now signed off and can safely allow someone else to use the workstation. The Public Sun Workstations are normally left on. PROBLEMS DURING SIGN-ON Now and then there's a problem at sign-on. Here are some problems and suggestions. You make a typing mistake: If you catch it while you are typing a line but haven't pressed Return, you can correct it immediately: Pressing the Delete key erases the last character that you typed. You do not get the Login prompt: If you see the message NFS server zookeeper.cns.syr.edu not responding still trying then the workstations are not presently working because their disk storage is not available. Login incorrect message. You may have mistyped your username or password: go back to step 2 under SIGNING ON A PUBLIC SUN WORKSTATION. If you made no mistake, see whoever gave you the username. BEFORE SIGNING ON Getting a username: You must have a username and password for the Public Sun Workstation Cluster in order to use one of its workstations. All Public Sun Workstation usernames are given out by Academic Computing Services: go to 116 Hinds Hall and ask for a Public Sun Workstation username. Finding Public Sun Workstations: Syracuse University has one cluster of 15 Public Sun Workstations located in room 1-211 of the Center for Science and Technology. A LITTLE ABOUT SUNVIEW The workstations run SunOS, which is Sun's version of Unix. Sunview is a window-managing system which makes using a workstation similar to using an Apple Macintosh computer, allowing you to get help and run some commonly-used programs using mouse-driven menus (most of the applications programs that we have added to the Public Sun Workstation Cluster are listed in the menus). It also lets you run more than one Unix program at the same time. Here are some tips on using Sunview: Windowing Terms: Following are definitions of some of the terminology of window-managing systems such as Sunview: background: The area of the screen not occupied by any window or icon. window: An area of the screen (usually rectangular) controlled by a particular running program. A window may be "closed", meaning the program continues to run as if the window were there, but instead of the window, there is a single icon on the background. You can open and close windows using the mouse. Windows may overlap each other without affecting the programs controlling them. JMW 5/89 ZOOHELP-1 Using Public Sun Workstations Page 3 frame: The thick lines around a window. icon: A small square area of screen, representing a closed window. You can "click on" an icon to open its window. mouse: An input device to let you move a cursor around the screen by sliding your hand in a similar motion across a desk-top. It is a small object that fits in your hand attached to the workstation with a wire. A mouse usually has one or more buttons on top. The mouse on a Sun Workstation has three buttons. button: A "mouse" button is one of the three buttons on top of the mouse. Sometimes a window has buttons: small areas of the window which you can click as input to the program controlling the window. cursor: A mark on the screen showing what input will affect. A Sun Workstation has a cursor usually shaped like an arrow controlled by the mouse which tells you what part of the screen will be affected if you press a button on the mouse. A window which uses keyboard input has another cursor for that purpose. click: To point the mouse cursor at some part of the screen, then press a button on the mouse. On a Sun Workstation, "clicking something" or "clicking on something" usually refers to pressing the left-hand mouse button. drag: To move a window or icon on the screen using the mouse. You drag an icon by pointing the mouse cursor at it, pressing the middle mouse button and holding it down while you move the mouse cursor to where you want the icon to be on the screen. You can drag a window by doing the same thing to the window's frame. open: To change a window from the "closed" to the "open" state. You do this by clicking its icon. close: To change a window from the "open" to the "closed" state. You do this by selecting the "close" command from its frame menu. Mouse Hints: The mouse for a Sun Workstation must be on a "mouse pad" to work. The Mouse Pad must be turned so that the longer direction is side-to- side. If you reach the edge of the pad while moving the mouse cursor, you can pick up the mouse and put it down in the middle of the pad to give yourself more room. Mouse Buttons: The right mouse button normally calls up a menu. Which menu it calls up depends upon where the mouse cursor is pointing. There are two standard windows: one invoked when the mouse cursor points to the background (the "background menu"), and one invoked when the mouse cursor points to an icon, or to the frame of a window (the "frame menu"). When the mouse cursor points to the interior of a window, the program controlling the window determines what sort of menu is called. Menus: A menu is a small special window that lists several programs or further menus that you may run. To use a menu, you "call it up and select a menu item", i.e. you hold down a mouse button (usually the right-hand button) and move the cursor to the line of the menu which you wish to run (the line will be highlighted) and let go of the button. If you decide not to use anything on the menu, move the cursor to the background before letting JMW 5/89 ZOOHELP-1 Using Public Sun Workstations Page 4 go of the button. A line of the menu marked with an arrow to the right (=>) indicates this line represents another menu. To display that menu, move the mouse cursor to the right arrow on the line. Help: The Public Sun Workstations have some help-explanations displayable with the mouse. Bring up the main menu and invoke the first line, marked HELP . An icon will appear with the words Don't Panic . Click this icon to open the Help window. The Help window has 11 labelled "window buttons" (e.g. "Introduction to the Cluster") which you can click for some help on a specific topic. Using Unix from Sunview: To use ordinary Unix commands, call up the main menu and select the Terminals menu, then select Shell Tool. A window will appear with the prompt for Unix. Point the mouse cursor anywhere in the window and the keyboard will now type to this window. You may use any Unix (SunOS) commands or programs. A Control-D will terminate that window, but you will still be signed-on and using Sunview. You may open a second Unix window, allowing you to run two programs at once. For example, you might edit a file in one window while compiling a program in a different window. JMW 5/89
