could these snippets be logs/reports regarding tweaking these devices for the use of other departments or persons?

I may have a systematic method for working these out.

Here is a completed chart for 'no zones'. The column gives the number of 'switch' commands in the sequence, the row gives the number of 'rotate' commands. (I mean no zones other than the one you need for zone-mount -- it's possible that one counts, in which case you'll likely max out at three extra zones. EDIT: I have now tested this. It appears once you have four (five if you're count the starting one) zones, the file system 'wraps around' and you're again dealing with the no zones area.)

Code:

   sw |     |     |     |     |
ro    |  0  |  1  |  2  |  3  |  4
------------------------------------
   0  |  x     x     x     x
      |
-------
   1  |master  TNI Suspic. Header Ioniser
      |
-------
   2  |unread  TNI  Yorke NanoImg Ioniser
      |
-------
   3  |master  TNI Suspic. Header Ioniser
      |
-------
   4  |  x     TNI  Yorke NanoImg Ioniser
      |
-------


pread, popen, and pwrite seem to be interchangable.

All of these end with 'cache'.

the rotate/switch commands can be added in any order
after the popen/pread/pwrite

One of these charts can be made for 'one zone', 'two zones', etc.

I stopped at four because I haven't been able to get anything to come up with more than four switches, rotates, or zones.

Just be very careful, it can be easy to mess up because of the directions being screwy. Bbuck gave f) ZO, MO, PO, RO, RO, CA as an 'approached by the master' message, but the actual sequence doesn't seem to give that. (I suspect he somehow went straight from the first rotate to the cache.)

EDIT: And pay special attention to the 'unread' ones compared to the ones that simply give invalid command grid (I give those an x). I think there may still be a way to do something special with those.

3 zones (4 zones if you count the starting one)

This time I didn't even bother with checking no rotates. It seems to be a requirement to have at least one.
Code:

   sw |     |     |     |     |
ro    |  0  |  1  |  2  |  3  |  4
------------------------------------
   1  |unread RNG    WHISK unread  ?
      |
-------
   2  |unread unread WHISK unread unread
      |
-------
   3  |unread RNG    WHISK unread unread
      |
-------
   4  |unread unread WHISK unread unread
      |
-------


Just for fun, checked 1 switch, 5 rotates-- got RNG again. I suppose it just alternates if you go past 4.

I couldn't work out a setup to check my ? spot, but I think it's a safe but that's also 'unreadable'.

I'm partway through 1 zone (2 counting the starting zone) but I need to head off. Can someone finish? I'm only checking rotate 1 and 2 now, based on the patterns of the previous charts.

1 zone (2 zones counting the starting zone)
Code:

   sw |     |     |     |     |
ro    |  0  |  1  |  2  |  3  |  4
------------------------------------
   1  |Camera Coffee Noise
      |              Control
-------
   2  |Camera Coffee Noise
      |              Control
-------

I've filled in the blanks on that. Still obviously lots more to do as there must be combos involving all the other commands - see the wiki for updates (including two new screens I found this morning)

Cheers jbd - well done Smile

Oh, and 1+4 zones appears to wrap back to 1+0, so that's all done I think..

Some background links

I've been doing some quick googling on some of the equipment, and there's a lot of particle physics going on. I should be doing some studying today Wink but here's some handy links to addle your brain with...

Quadropole (/Quadrupole) Magnets:
http://en.wikipedia.org/wiki/Quadrupole_magnet
These seem to be used in both particle accelerators and possibly Electron Optics, although no info on Wikipedia for the latter.

Plasma Wakefield Accelerators:
http://www.slac.stanford.edu/grp/arb/e164/OVERVIEW.htm
And see pages 2-4 of this PDF, which also mention Ionising Lasers (Reynolds Ionisers + High Power Laser?)
Although note the item mentioned from the crypto dept is actually a controller. Building an accelerator seems a possible option at this stage, although how that's related to the Cube I'm not sure...

Nuclear Delay RNG:
http://en.wikipedia.org/wiki/Hardware_random_number_generator
I can't work out how this fits in - everything else seems like measurement devices, etc. Oh, wait. RNGs, crypto. Duh. Maybe this a herring?

That's kind of as much investigation as I've done so far. Unfortunately(?), I'm not a particle physicist, so couldn't really say how these things really fit together, or what it could be used for. Wikipedia's page on particle accelerators mentions such joys as black hole production though.

Well it is an ancient artifact. It's probably only USB 1.0...

[UPDATE]

Caine has updated his blog. Not sure if I should be reposting what he said, or starting a new thread or what, but I thought the most logical thing to do would be post here. If a repost of Caine's blog entry is needed someone more knowledgable about these things than me could do it pretty please?

He gave us two new programs...one is another way to get to Big Nothing, and the other is a repeating loop that flips the system out. He said it goes funny and spews random files, but I didn't see any files. But the interface twisted and flickered, and that was kinda cool.

The overload program went as follows:
MO - - - - / - FL PR - - -/ - RO - - - / - - - - - / - - RU - - /

From the way Caine was inciting us to try and crash the system, I got an idea...perhaps if a lot of us tried something like this at once? When he first gave us the link, he did say for all of us to bombard it, maybe that was a clue? Obviously our answer is not going to be found playing "nice" by the system. (I just hope we don't lose Nev his job...or worse)

Oh yeah, and Caine seems a bit put out by our lack of response, I guess no one has emailed him to let him know what we have found so far?

I sent Caine the charts and my explanation. I'm not up for typing up all those messages we got right at the moment, though.

I just set up a really big infinite loop and got the logs thing again. I don't know if there's anything in infinite loops other than the logs. Maybe there's an alternate way to make it crash?

Had a theory that the position of "run" in the infinite loops dictated which message you got. Seemed to work for

Z CO - - - / RO CO - - - / Z Z - - -

But yielded nothing new anyway..

The other theory is that the #echo... file was the start of inetd.conf on the machine. This is the file that decides what services a particular machine runs.. Thanks to MJ, we know crypto.perplexcityacademy.com runs the following:

22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
113/tcp open auth
135/tcp filtered msrpc
136/tcp filtered profile
137/tcp filtered netbios-ns
138/tcp filtered netbios-dgm
139/tcp filtered netbios-ssn
412/tcp filtered synoptics-trap
445/tcp filtered microsoft-ds
674/tcp open acap
993/tcp filtered imaps
995/tcp filtered pop3s
1720/tcp open H.323/Q.931
4444/tcp filtered krb524
6699/tcp filtered napster
7597/tcp filtered qaz
12345/tcp filtered NetBus
31337/tcp filtered Elite

3-dimensional file system

I think I've worked out how the filesystem behind this works now, mostly thanks to the various diagrams on the wiki and caine's new info. Spugmeistress posted this info to the wiki discussion page, but here it is again in case no-one's checking it...

First up, these are the directions that each comand moves in. If blocked (either by a side, or by a previously used square - see below), then it progresses to next listed direction. However, I haven't explored these latter moves extensively, so there are gaps. Directions in brackets are unconfirmed...

Mount - SE
Zone - W, N, E, NE, (NW?), SW
Switch - SE
Rotate - N, NE, (E?), S
Copy - S
Flush - S, SE (Seems to move BEFORE flushing - see below) doesn't seem to go upwards at all
PWrite - E, S
POpen - E, S
PRead - W
Cache - No direction
End - No direction

The filesystem can be thought of as a three-dimensional array, which seems to loop back on itself in all 3 directions. Each dimension is controlled by one of the ZONE, SWITCH or ROTATE commands, leading to the output we're seeing and why more than 1 configuration leads to the same file. Not all axes are the same length along the ROTATE axis, so sometimes you just get 1 file per SWITCH axis before wrapping around, sometimes you get 2.

N.B. This means that doing a ZONE keeps the SWITCH and the ROTATE pointers in the same place, i.e. if you've done 2 switches and 1 rotate, then do a zone, you'll be at the same position in the file system, but on a different zone.

Breaking the System:

Caine has given us one example, with an infinite loop, which we also found by accident. Usually, the execution of commands cannot loop as the executing program keeps track of which squares have been used already. If a command tries to enter a used square, it fails and moves to the next directionon its list. However, I think the FLUSH command clears out this "stack" of used squares, which means we can enter squares we have already been to and produce an infinite loop. For some reason, what should loop doesn't always get accepted by the "parser", i.e. only some loops work and crash the system.

The loops below (following some other commands) seems to "work" (i.e. break) but they may or may not be dependent on the precending commands. I think they may also need to be "inescapable" - e.g. Flush doesn't seem to move upwards at all, so is best placed at the right-hand edge, surrounded by other commands to the left and below.:

FL RO PR
RO PW FL ZO
RO FL (with Flush at edge, no other way down)

Other combos that should loop sometimes don't. Not sure why.

Finally, I think, judging from Caine's second posted excerpt from the inetd.conf file (#echo etc) we need to find the second way to break this thing.

The only thing I can think of right now is that you can position the ROTATE and SWITCH dimensions at a valid file, then increase ZONE to switch to a zone where that R/S position is no longer valid. This might break it, but I haven't got time to test it now.

Hope that helps a little anyway.

Hey I think i got another one...

Mo Zo Ro Sw -- / -- Ro -- -- Po / -- -- Sw Zo Zo / -- -- --Sw -- / -- -- Ca Pr Zo /

Gives:

Quote:
CRYPTO PARTS REF: 122C76-3S
EXTERNAL REF: 45442R

DESCRIPTION: Imaging/Klebold plates; networked in array for large-scale 3D spatial scanning. Double redundancy.


Can't see it on the wiki!

I'm maybe thinking that there's something to do with using Pread and not getting an error message... but thats just me thinking out loud Smile

Looks like it's related to the stolen Reynolds Ionizers and Klebold Plates.


Maybe this confirms that the Department of Cryptology has the stolen equipment...

I was wondering if the Big Nothing was going to get a mention at any point. Also, I didn't realise that the waviness we discovered was 'breaking' it!!

Still plugging away. Trying to create a big infinite loop.

Throw off the shackles of the first Zone!!

It also looks like you can start a Mount at any point on the left hand side (except the bottom of course)

I've made an interesting discovery...

I've made the grid

- Pw Po F -/M Ro Z F -/- Po Ro Co -/ - -Ro Z

Run anywhere except top left

Because it's a loop, the Operation in Progress appears and nothing happens.

What's even more interesting is that it continues to say Op in Progress after I have removed/shuffled the other commands.
Mebbe after inputting another command something juicy will happen... or not. I'll keep trying.

Yeh I got a similar thing with:

Mo Zo Ro Ro Pw / -- Ro FL Co FL / -- -- FL Ro Po / -- -- Ro Ro Ro / -- -- -- Ro Zo

with run anywhere... Interesting... I just thought I'd cocked it up Laughing

EDIT: If I put :

Mo Zo Ro Ro Pw / -- Ro FL Co FL / -- -- FL Ro Po / -- -- Ca Ro Ro / -- -- -- Ro Zo

(note the changed Ca) I get the smart dust but with three copies on the same page...

I'm starting to think this actually is my computer going wierd!

Umm, interestingly, I think you may actually have crashed the machine, well the script to be precise..

"Allowed memory size of 8388608 bytes exhausted (tried to allocate 136704 bytes) in /var/www/perplexcity-events/gateway/commandinterface/commands.php on line 261"

Hard to tell what's in game and what's out sometimes Smile
