Backdoor

Summary

After discovering that V called someone at the Academy's Crypto Department, Caine heads over to Crypto to investigate. He runs into his friend Neville Clark, who is talkative, if obfuscating. The Cube Hunters entice Nev into sharing more information by giving him a puzzle, designed by jbd, to solve. Nev takes the bait, and gives us a backdoor that leads to a gridded file system.

Dragging the commands onto the grid to create various configurations yields a series of log snippets. Some of the logs resemble the Perplex City Errorlogs that were found before the puzzle cards were released.

The interface can be accessed at the following URL:

http://events.perplexcity.com/gateway/commandinterface/index.html

As of 12:36, 1 July 2006 (PDT), the puzzle is still being worked on. Join us in #syzygy, or see the discussion on the Talk page or at Unforums.

Commands

Through the combined work of jalapenodude, pelrun, and jbd, #syzygy has determined that the commands appear to work as follows:

The program pointer starts in upper left corner.

Directions:

popen - east
pread - west
mount - se
pwrite - e
switch - se
copy - s
flush - s

'rotate' does something different depending on where it is executed:

 e  e  e  e  s
 s ne  n  n  s
 e  n ne  n  s
ne  n ne  n  s
ne  n ne  n  n

The same goes for 'zone':

e e e w s
s w w n n
e e e n w
n w w n n
n w w n n

'end' ends execution whenever it gets hit on a specific error message. It is very good for testing where the code is going. 'cache' seems to only work as an end point. 'run' can go anywhere that the program pointer isn't reaching.

Configurations

Here are the various configurations and logs that have been discovered.

Config 1: Smart Dust Cameras

Configuration: zone, mount, run, rotate, rotate/ - - popen, zone, cache/ - - pwrite pread -/ - - rotate - end/ - - end - -

Config 2: Approaching the Master

Configuration: zone, mount, run, rotate, rotate/ - - popen, rotate, cache/ - - end - -

Alternate Configuration: zone, mount, run, pwrite, cache/ - - popen, rotate, cache

Config 3: Neuro Scanner

Configuration: zone mount run switch switch/ - - popen rotate cache / - - end - -

Alternate Configuration: zone mount run switch rotate/ - - popen rotate cache / - - end - -

Alternate Configuration: zone mount run cache -/ - - popen rotate -

Alternate Configuration: zone mount run - -/ - - switch cache -/ - - - rotate -

Config 4: Laser

Configuration: zone mount run -- –/copy zone zone cache --/copy pwrite rotate -- --/copy rotate -- -- --/rotate -- -- -- --

Config 5: Sphere

Bookmore discovered this, but we have been unable to reproduce the configuration so far. Possible configuration: zone mount run -- / copy zone zone cache - / copy pwrite rotate -- / copy rotate --- / switch ----

(Reference numbers here, I don't have them) DESCRIPTION: Physics/Baker Spherical Magnetic Containment field; interfaced with dedicated fibre network. Tested at 120% maximum tesla strength to ensure no field leakage.

Config 6: Gatehouse 24

Configuration:' Zone Mount Run Flush -- / -- -- Copy Switch Flush / -- -- Pwrite Rotate Rotate

When this configuration is run, a message Operation in progress appears. The screen then distorts and wavers. Finally, a log appears. Discussion on Unforums suggests that the logs may rotate, or appear randomly.
