This was another escapade on the ICL 4130 running KOS. By this time I was
a (supposedly responsible) postgraduate.

The 4130 was running out of disk space, but it was nearing the end of its
10 year funded life. It had four 2MB disks, but needed more; however, it
was not cost effective to buy more disks, and, I believe, an extra disk
controller. Indeed, I am not sure that they were even available.

Two members of staff (one being the big boss) thought up a cunning plan
for cheap disk space. This used a PDP-11 as a kind of file server. One of
the staff built a hardware interface between the 4130 and the PDP-11, and
the other wrote the link software. There was also a little extra software
in the PDP-11.

The basic idea was that the PDP-11 appeared as an extra disk - the current
disks had single digit numbers, and the disk on the PDP-11 became disk 99.
The PDP-11 ran its manufacturers' operating system - a pretty basic one
called DOS/BATCH. Filenames on the 4130 were a maximum of eight
characters, whereas they were 9 characters on the PDP-11. One could thus
directly map filenames from 36 users on the 4130 to a single user on the
PDP-11, by using the extra letter or digit to differentiate files for
different users (there were a limited number of user accounts in DOS/
BATCH).

This all worked surprisingly well. The disk on the PDP-11 was an RP02,
which was 20 megabytes; this was a vast improvement. A second disk was
added later.

Until I came along! One day, I had written a program to do something
pretty innocuous; I forget what it was. I accidentally got it into a loop
writing to a file, and managed to fill up the rest of the 20 megabytes. I
realised what I'd done, so I simply deleted the rather large output file.
This would have been OK, but ...

DOS/BATCH used the system of 'block chaining' to construct files in its
filing system. Essentially, files were linked lists of blocks, with a
bitmap or a free list recording free blocks. When I deleted my large file,
its deletion involved laboriously crawling down the very long chain of
blocks in the file, returning each one and marking it as free. This took a
long time - so long, in fact that the 4130 thought the PDP-11 had crashed.
The software was very simple - it did the easiest thing - it halted the
machine.

So I brought the University mainframe to a standstill by deleting a file.

If your computer's program counter is in low memory, there are
all sorts of fun ways to create loops, typically by copying
the instruction's own address into the PC. On the Univac 9300
(their answer to the IBM 360/20), this could be done by loading
a register with the address of an STH instruction (it only had
16-bit addressing) that stored the register into the program
counter. You could also use MVC to copy the address of the
instruction from an area in memory to the program counter.
For some addresses, MVN and MVZ would also work, as would
NC, OC, NI, and OI (it didn't have XC or XI, though).

The 9300 also had an Add Immediate instruction, which would
sign-extend the immediate operand and add it to the specified
halfword in memory. If this memory location was the location
of the program counter, adding -4 would back it up to the same
instruction for a one-instruction loop. I came up with a
fun variation on this one; I filled all of memory with copies
of an AI instruction that decremented the program counter by
8, rather than 4, and preceded them by an unconditional branch
to the end. The resulting loop would execute backwards.

I think the college (now university) I was at thought me "unworthy",
mostly because I feel they (central computing services) hated me,
but that's OK, I hated them, but had to tolerate them to get stuff done...

So after a holiday break when they had upgraded the Pr1me system (a
wretched overloaded and underpowered piece of shite that my Apple II
could better) to have some nicer scripting language (CPL?) I decided
to test the filing system to see how many levels of directory I could
create... I wrote a program to recursively create and descend, as you
do... I also put a bit into it to recursively descend and delete...

So I left it running, then realised I was late for a class or something,
stopped it and promptly forgot about it.

The next day I was summoned (again) to the head of computing service to
explain why I did it (because I could) and to be told that it caused
their shitty backup service to fail. (Because they were idiots who
couldn't code their way out of a paper bag).

I was told they had to manually go down several 100 levels and delete
the directories by hand and that if I were to do it again it would be
the end of my college life...

When I said why didn't they just write a program to do it, or look at
mine (they had a known history of looking at *all* my code as I was
under constant surveillance) I was just met with blank faces.

Morons, the lot of them. Biggest preventers of information entertainment
and I was glad to move out of computing and into Engineering where we had
real computers to use - more Apple IIs, CP/M and eventually BBC Micros,
all which exceeded the capabilities of the Primes at the time. Or felt
like it. (It could take over a day for a simple program to get through
their batch system, such was the overloaded service they tried to run).

So you deliberatly tried to sabotage the system.

I worked for the Computation Center in college and we
had a student like you (who ended up maliciously deleteing
a bunch of files out of spite). He was expelled.

It's not their job to clean up from your messes. They had
much better things to do with their time.

So transition from Rev 18 to Rev 19. In addition to CPL and other
things, that's the boundary where the password on a top level UFD
quit being the whole login authentication mechanism, and a database
of users and rights sprang into existence.

PRIMOS had pathname length limits, and parts of the system had directory
depth limits. I'd be astonished if they wrote their own backup tool,
but MAGSAV was one of the places I think I recall fixes for on the
pathname depth thing.

The PRIMOS filesystem _also_ had the chained disk record concept for
files. Our application had really large MIDAS (think ISAM) data files
-- some sites had several that were over 40 MB each. Us deleting those
files during file rebuilds was part of the cause of them making the OS
not just take the lock and do the whole chain in one go, basically
hanging the system for several minutes.

My favorite bit of CPL was the &args directive for parsing the command
line. Very accurate, sometimes. :)

No. I was a curious student who wanted to know more about the system. Nothing
I did on that system was ever an act of deliberate sabotage.

And I'll leave the rest at that.

Yeah, sounds like some people I had to deal with at university to. I
wasn't under surveillance, but simple suggestions would turn the main
campus computer department into a tizzy of denial of reality.

I had requested newsgroups. They said it was impossible. A professor
on main campus set it up on a x86 system under ms-dos. And I tested
it. This was in 1990.

Main campus computer department freaked out. But the professor had
tenure. Slowly they eventually gave newsgroup access to the rest of
the university.

I got this group via digest back then. My email address back then had
cp6.bitnet in it.

I always say Morris owes me for hernia surgery! When the worm started
hitting, one of the first things that became clear was it targeted
BSD Vax & Sun boxes. So we had a clunky Apple Mac II running A/UX
that I hoiked around the computer room to put it up as a UUCP relay
in front of our network so we could still have email on an immune
system to track worm news & fixes.

Turns out I shouldn't have lifted that Apple box..

That reminds me... wasn't there a worm hitting Microsoft IIS around 2000
or so? I remember watching apache logs on my well performing trusted
OpenBSD web server at work seeing copies of the worm trying to infect it.
It made a real mess out of my log files, but that was about it! ;)

Thank you. :)

Speaking of which, one April 1 at the university's student terminal
one of the staff posted a sign warning that they were having trouble
with the FORTRAN compiler. Everyone's WATFOR jobs came out printed
right to left, with a banner at the bottom of the report saying
"*** LOOF LIRPA STRIKES AGAIN ***". (They offered a free re-run
the right way around for students desperately trying to get an
assignment handed in.)

Some years later at a PPOE, I inserted a bit of code into the
machine's print routine to do the same thing. I even added a
boustrophedon option

so that people's
stuotnirp
would come out
gnihtemos gnikool
like this.

Sorry for the mispelang.

So when it hit, I was at an inter-agency facility for
several days of meetings.

It was populated with employees from the Community. Day 0, we
were standing in the hallway BS'ing as to WTF was going on.

I have a very sardonic sense of humor, so with a dead-pan voice
said "Wonder if the gang at DOCKMASTER launched it to help
justify their budget?"

The people from DOCKMASTER's parent Agency wanted to lynch me
right then and there. But the facility Leader type knew me well,
and while standing in his nearby office door said "Hey, that's
right, NCSC's budget comes up this FY." Group silence.

The next day, or was it the day after that, word got out about
RTM. Suddenly I was confronted with "How the %%*%^& did you
know about this?" I just said "Sorry, Need to Know..." [ALWAYS a
good answer...]

Year later, I was introduced to his father by a mutual friend
while at the Crypto Museum. I didn't bring the Worm up....

My filling-up-disk-space story involves, not something my code did, but
something the vendor’s compiler did.

This was DEC’s COBOL compiler on a PDP-11/70 running RSTS/E, during my
undergrad days. It was such a resource hog (280K-byte executable, as I
recall, heavily overlaid to run on a machine with a 16-bit address space)
that it was kept chained up in its own batch queue, to prevent students
running more than one instance of it at a time.

One day, we noticed the system disk filling up. A COBOL compile had
created a log file that had grown to 15,000 blocks, repeating the same
message over and over, something like “INVALID SECTION HEADER. SECTION
HEADER IGNORED.”. Basically, the lack of disk space was making the system
quite sick indeed.

What happened was, a student had made a typo: “IDENTIFICATION DIVISON”.
The compiler barfed on that, but somehow instead of recovering by skipping
to the next statement, it kept trying to parse that same statement over
and over.

(I studiously avoided COBOL during my entire student days. And the first
job I got after graduating involved--you guessed it--spending much of my
time writing COBOL.)

It still works.
