==================== THE IBM VMSSP SYSTEM ==================== PART ONE BY THE MOTORHEAD INTRODUCTION ------------ IBM's VMSSP mainframe operating system is for one of the most sophistocated computers available today, the IBM 303x and 308x families of processors. These computers can handle vast quantities of memory, handle hundereds of users logged in at one tim e, plus access many high-volume hard disks at once. To someone who has only used an Apple, a VMSSP computer would definitely fit the title 'supercomputer'. This series of tutorial text files will attempt to give the reader enough knowledge about the sys tem to perform some usefulddestructivewwhatever tasks on hishher own. LOGGING IN ---------- Logging onto the computer is, of course the first and most important step. The first thing you have to find is a valid username. This can be hard to do, because there is, to my knowledge, no way of seeing who is on a system before you have logged in . Very clever for security, but not too friendly for the average userhhacker. If you need to hack out a username, they are from 1 to 8 characters long, and have a 1-to-8 character password associated with them. Start out by trying such common first and last names like 'Jones', etc. The login command on a VMSSP system is, quite simply, LOGIN (or LOGON). You would issue the login command like this: .LOGIN [] (The '.' is the prompt, and is optional; if you don't supply a password, the system will prompt you for one.) If the username you have tried isn't valid, you will get the message: DMKLOG053E NOT IN CP DIRECTORY If the password you've tried is wrong, this message will appear: DMKLOG050E PASSWORD INCORRECT If there is already somebody logged in on the account you've tried, you will get this message: DMKLOG054E ALREADY LOGGED ON {LINE|GRAF|LUNAME} raddr Once you've gotten a correct usernameppassword combination, you will be greeted with this line: LOGMSG- hh:mm:ss mmdddyyy This indicates when the system logon message was most recently revised. Then the system logon message will be displayed, and you will be told if you have any files waiting for you in your 'reader' (which will be explained later). This message will look like this: FILES: {nnn|NO} RDR, {nnn|NO} PRT, {nnn|NO} PUN One important thing to look for is one of the following messages: LOGON AT hh:mm:ss zone weekday mmdddyyy RECONNECTED AT hh:mm:ss zone weekday mmdddyyy RECONNECTED means that you have ben re-connected to a session that was stopped using the 'DISC' command instead of just logging out. You should get off this as soon as possible, as the person who disconnected probably will be wanting to get back onto the ir account. Now that you know how to log into the system, you are ready for some of the more basic commands of the operating system. QUERY ----- The QUERY command is used to get various bits of information about your session on the machine, and various other system statistics. There are many options associated with this command, and only a few of them will be described here. (Note: the QUER Y command can be abbreviated to just 'Q') Q TIME - display the current time and date on the screen Q Reader|PRinter|PUnch - displays on the screen files, if any, in the reader. Q DISK [mode] - Gives information about the various 'minidisks' attached to the session at one time. Q SEARCH - Similar to Q DISK. Q USERS - Tell how many users are logged on to the system. Q NAMES - give the usernames and terminal addresses of all users logged onto the system. LISTFILE [ []] --------------------------- The LISTFILE will give a list of all or some of the files on one of the minidisks attached. The wildcard character '*' can be used to search for groups of files with a certain filenameffiletype. GIME
