- The Hackers Guide to RSTS-E 8.0
-
- Data Line. TWX 650-240-6356
-
-
- Rsts is one of the most versatile operating systems available for the PDP-11
- series of computers. It can emulate both RSX and RT-11 (though not fully),
- and is often a choice where multiple concurrent operating systems must be
- online. I was a system manager on an 11-23 for about a year and learned a
- fair amount about the OS (perhaps forgetting a good deal in the interim).
- This phile applies to release 8.0 and the entire 7 series. By the way,
- version 9.0 is it - DEC is discontinuing RSTS with that release and using 9.0
- as a bridge to VMS for the PDP-11 series. The logon will tell which version
- you are hacking.
-
- If the SYSTAT-before-logon has been disabled (It probably has), no big
- worry. Account 1,2 must be present on the system and contains most of the
- system utilities. On booting, the account is called at least 8 times to put
- batch processors and spoolers online. Changing [1,2]'s passwords in the
- command file is a tedious process - most system managers are too lazy, so it
- won't change often. Oh yes, the default PW for 1,2 is SYSLIB. This
- knowledge should cut hacking time considerably for many systems. When you
- get in, RUN $MONEY. This gives all accounts, KCT's (Billing units),
- accesses, time on system, and PASSWORDS, if you ask. Don't reset the system
- when it asks, it merely zeroes the program and not the hardware, but could
- tip someone off that he 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 Cluster size, I
- prefer 4. It's large enough to get fast disk access, but small enough so
- that little space is wasted for small files. Cluster size is shown (CLU or
- CLS) on MONEY and on DIR/FULL. Follow conventions and you'll stand less
- chance of 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 this
- from a privileged account or you'll miss about half of the best commands.
- HELP SYSTAT will give a thorough overview of the system setup & status
- program.
-
- RUN $SYSTAT (or just SYS if the Concise Command Language is set up
- normally). On the left is a report of te system users including all
- background jobs (print spoolers, batch processors and the like), their
- keyboard, and what state they are in (RN=run, ^C=waiting for input,
- DCL=logged on, no program running, DR=Disk Read, DW=Disk Write). To the
- right is a list of 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 the leftmost column. Simply type UT KILL # and he's totally gone,
- without so much as 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 gives the
- utilization readout on a 20 second basis, or whenever a key is struck. The
- program 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
- long text file (DIR [*,*]*.txt) and COPY LP1:=filename. Don't forget the
- colon when referring to keyboards or printers.
-
- Try DTR. If DATATRIEVE is online, you can set up a database of huge
- proportions. Again, full help is available. SET GUIDE (configure your
- terminal for VT-100) and it takes you through every step.
