==Phrack Inc.== Volume One, Issue Two, Phile #8 of 9 The Hackers Guide to RSTS-E 8.0 Data Line. TWX 650-240-6356 Rsts is one of the most versatile operating systems available forthe PDP-11 series of computers. It can emulate both RSX and RT-11 (though notfully), and is often a choice where multiple concurrent operating systems mustbe online. I was a system manager on an 11-23 for about a year and learned afair amount about the OS (perhaps forgetting a good deal in the interim). Thisphile applies to release 8.0 and the entire 7 series. By the way, version 9.0is it - DEC is discontinuing RSTS with that release and using 9.0 as a bridgeto VMS for the PDP-11 series. The logon will tell which version you arehacking. If the SYSTAT-before-logon has been disabled (It probably has), no bigworry. Account 1,2 must be present on the system and contains most of thesystem utilities. On booting, the account is called at least 8 times to putbatch processors and spoolers online. Changing [1,2]'s passwords in thecommand file is a tedious process - most system managers are too lazy, so itwon't change often. Oh yes, the default PW for 1,2 is SYSLIB. This knowledgeshould cut hacking time considerably for many systems. When you get in, RUN$MONEY. This gives all accounts, KCT's (Billing units), accesses, time onsystem, and PASSWORDS, if you ask. Don't reset the system when it asks, itmerely zeroes the program and not the hardware, but could tip someone off thathe system had been hacked. Personally, I like running out of a new account, so RUN $REACT.Pick a new account #, making sure the first number (before the comma) is a "1"to get full privilege. Accept defaults for disk placement. As for Clustersize, I prefer 4. It's large enough to get fast disk access, but small enoughso that little space is wasted for small files. Cluster size is shown (CLU orCLS) on MONEY and on DIR/FULL. Follow conventions and you'll stand less chanceof being noticed. RSTS has some of the most complete HELP files short of a CDC mainframe.HELP HELP will give the forst screen of the nested menus. Be sure to do thisfrom a privileged account or you'll miss about half of the best commands. HELPSYSTAT will give a thorough overview of the system setup & status program. RUN $SYSTAT (or just SYS if the Concise Command Language is setup normally). On the left is a report of te system users including allbackground jobs (print spoolers, batch processors and the like), theirkeyboard, and what state they are in (RN=run, ^C=waiting for input, DCL=loggedon, no program running, DR=Disk Read, DW=Disk Write). To the right is a listof busy I/O devices. At the end is a full report of Disk names (DR:=Hard, DU:=floppy), and space allocated/free. To cause some havoc pick a target KB,preferrably one running a financial type program. Note the Job # in theleftmost column. Simply type UT KILL # and he's totally gone, without so muchas a logoff message. If done during a Disk Write - get out the backups!! If just tying up resources is more your game, RUN $VT50PY. It givesthe utilization readout on a 20 second basis, or whenever a key is struck. Theprogram itself uses a lot of CPU time, so when the Interval <20>? comes up,enter a 1 and watch the EXEC percent go through the roof. If wasting paper is more your style, find the KB: number of the printer(KB0: is the console) from SYSTAT when it's in use, or try LP1:. Find a longtext file (DIR [*,*]*.txt) and COPY LP1:=filename. Don't forget the colon whenreferring to keyboards or printers. Try DTR. If DATATRIEVE is online, you can set up a database of hugeproportions. Again, full help is available. SET GUIDE (configure yourterminal for VT-100) and it takes you through every step.
